    MEMORANDUM OPINION
    Plaintiff Keith B. Diggs is an African-American male
    formerly employed by the United States Postal Service (“the
    Postal Service,” “USPS,” or “the agency”).   He claims that his
    employer discriminated against him on the basis of his race,
    gender, age, and disability, retaliated against him for
    complaining about that discrimination, and subjected him to a
    hostile work environment in violation of Title VII of the Civil
    Rights Act of 1964,   42 U.S.C. § 2000e et seq. (“Title VII”).
    Defendant has moved for summary judgment on all of plaintiff’s
    claims.   Upon consideration of the motion, the response and reply
    thereto, the applicable law, and the entire record, the Court
    GRANTS defendant’s motion for summary judgment.
    I.   BACKGROUND1
    Plaintiff began working for the Postal Service on February
    14, 1987.   He was working as a Tractor-Trailer Operator, Full
    Time, Motor Vehicle Craft before he sustained an occupational
    injury that rendered him incapable of performing the duties of
    that position.     From May 20, 1997 until April 20, 1998, plaintiff
    was on leave due to this injury, and he received workers’
    compensation through the U.S. Department of Labor Office of
    Workers’ Compensation Programs (“OWCP”).    (Pl. Opposing Facts
    [“Pl. Facts”] at 3.)    In March, 2008, he provided USPS with
    documentation from his health care provider that he could return
    to work subject to certain limitations.    As a result, on April
    17, 1998 the USPS offered plaintiff a limited duty rehabilitation
    1
    Unless otherwise noted, these facts are drawn from
    defendant’s statement of material facts and were not disputed by
    plaintiff. The Court notes that plaintiff has not complied with
    Local Civil Rule 7(h). While plaintiff provides a few record
    citations in his statement of material facts, he overwhelmingly
    fails to include “references to the parts of the record relied on
    to support the statement” as required by Rule 7(h). See generally
    Pl. Opposing Facts [Doc. 56-2]. A district court “is under no
    obligation to sift through the record . . . in order to evaluate
    the merits of [a] party's case.” Jackson v. Finnegan, Henderson,
    Farabow, Garrett & Dunner, 
    101 F.3d 145
    , 154 (D.C. Cir. 1996).
    Rather, consistent with Rule 7(h), a court determining whether to
    grant summary judgment may rely on the parties’ separate
    statements of material facts and the record material they
    reference, and may “treat as admitted all facts not controverted”
    by competent evidence in the statement of genuine issues filed in
    opposition to the motion. See Waterhouse v. District of Columbia,
    
    298 F.3d 989
    , 992 (D.C. Cir. 2002).

    job offer.2   (Pl. Att. 1, Ex. 7 (Memo from K. McGovern to K.
    Diggs.))
    Plaintiff accepted the rehabilitation job offer.   He
    returned to work on April 25, 1998 in the position of full-time
    Modified Mail Processor at the Curseen-Morris Processing and
    Distribution Facility (“P&DC”) in Washington, D.C..
    Plaintiff’s second amended complaint alleges multiple claims
    arising from eight years of alleged discrimination and harassment
    by his superiors from 1998, when he returned to work at the
    Postal Service, until his employment was terminated in 2006.
    Pending before the Court are the events underlying five separate
    administrative complaints, two decisions from an EEO
    Administrative Judge, and three decisions from the EEO’s Office
    of Federal Operations.   This opinion considers, and resolves, all
    of plaintiff’s underlying claims.
    A.    Plaintiff’s Medical Conditions
    As set forth above, plaintiff suffered an occupational
    injury in May 1997 that rendered him incapable of performing his
    2
    As this Court has explained, “for workplace injuries, the
    Postal Service offers ‘limited duty’ assignments . . . because
    the Federal Employees Compensation Act (“FECA”), 
    5 U.S.C. § 8101
    et seq., requires that federal employees injured on the job be
    compensated for their injuries, and the Secretary of Labor
    requires that the Postal Service make special efforts to employ
    those injured employees, who will otherwise be compensated for
    doing nothing. The [OWCP] administers the FECA and is required
    to provide for limited duty jobs to accommodate employees with
    compensable job-related injuries.” Franklin v. Potter, 
    600 F.Supp.2d 38
    , 58 n.7 (D.D.C. 2009) (internal citations omitted).

    duties as a motor vehicle operator.    On March 13, 1998,
    plaintiff submitted to USPS a Duty Status Report (Form CA-17).
    This form is used by OWCP “to assess whether an employee who has
    suffered a work-related injury can be accommodated with limited
    duties that do not interfere with the employee’s medical
    restrictions.”   Smith v. U.S. Postal Service, 
    36 Fed. Appx. 440
    ,
    444 (Fed. Cir. 2002).   On or about March 27, 1998, he submitted a
    Work Restriction Evaluation Form (Form OWCP-5).   Both forms were
    signed by Barbara A. Shaver, CRNP (Certified Registered Nurse
    Practitioner).   Nurse Shaver diagnosed plaintiff with a herniated
    disc.   (Pl. Att. 1, Ex. 19d (CA-17, Mar. 11, 1998).)   She
    described her clinical findings as “pain in back radiating to
    right leg.”   (Id.)   Nurse Shaver also diagnosed plaintiff with
    degenerative joint disease in his right knee.   (Id.)   She stated
    that plaintiff had been totally disabled until March 16, 1998,
    and that he was able to resume work, but would have a partial
    disability from March 16, 1998 to September 16, 1998.   Nurse
    Shaver further determined that plaintiff could resume work for
    eight hours per day subject to, inter alia, the following work
    restrictions: intermittently sit and walk eight hours, squat,
    kneel and stand four hours, lift up to 20 pounds, climb and twist
    two hours, push and pull up to 30 pounds.   Nurse Shaver concluded
    that plaintiff was permanently unable to drive a tractor trailer.
    4
    (Pl. Att. 1, Exs. 19d and 19o (Shaver Evals. Mar. 11, 1998 and
    Mar. 27, 1998).)
    As a result of his workplace injury and the documentation
    plaintiff presented, the Postal Service offered plaintiff a
    limited duty assignment.    Specifically, on April 17, 1998, the
    USPS extended plaintiff a Rehabilitation Job Offer with the
    following duties: “employee will be required to start equipment,
    clear jams that don’t require hand tool, and notify maintenance
    of machinery malfunction.   Employee will clear mail from bins,
    and place in trays, and load letter mail onto ledge to be
    processed through machinery.”   (Pl’s Att. 1, Ex. 7.)   This job
    offer was determined to be “within the following medical
    limitations: Employee is able to intermittently sit and walk
    eight hours, squat, kneel and stand four hours.   Employee is able
    to lift up to 20 pounds, climb and twist two hours.”    (Id.)
    Later in 1998, Dr. Steven Taub evaluated plaintiff following
    a flare-up of symptoms after he stooped to light fireworks on
    July 4, 1998.   (1998 Report on Investigation (“1998 ROI”) Exs.
    19A-C (Taub Consult Oct. 6, 1998).)3   He diagnosed plaintiff
    “with known . . . disc disease causing low back problems,” and
    advised that “bending, stooping, lifting, twisting, and excessive
    3
    The record in this case contains three EEO Reports on
    Investigation (“ROI”): 1998, 2000 and 2006. The ROIs contain the
    EEO’s case files for plaintiff’s EEO complaints. They are
    referenced throughout as “1998 ROI”, “2000 ROI”, and “2006 ROI”.
    5
    sitting can exacerbate the condition.”      (Id.)   Dr. Taub advised
    plaintiff to “try to change his posture frequently with sitting
    no longer than 15 minutes at a time and no excessive bending,
    twisting or lifting.”   (Id.)    Dr. Taub did not evaluate plaintiff
    for specific functional capabilities. (Id.)
    Plaintiff submitted a Duty Status Report (CA-17) to the USPS
    EEO Office in May 2003.   (Pl. Att. 4, Ex. 6 (Form CA-17, Exam
    Date Mar. 25, 2003, signed May 20, 2003).)      He was specifically
    evaluated for his ability to perform the qualifications of
    Automation Mail Processor.    Form CA-17 lists the usual work
    requirements for the position, and requires the employee’s
    medical provider to state whether the employee can perform these
    duties.   Plaintiff could perform most, but not all, of the usual
    work requirements for Automation Mail Processor.      He could (1)
    lift 20 pounds intermittently for eight hours; (2) stand
    intermittently for four hours; (3) walk intermittently for four
    hours; (4) perform simple grasping continuously for eight hours;
    and (5) perform fine manipulation, including keyboard skills, as
    required by the position.     (Id.)    He could only sit
    intermittently for four hours, however, while the position calls
    for eight, and he could not perform any above-the-shoulder work
    while the position calls for four hours of intermittent reaching
    above the shoulder.   (Id.)
    6
    The 2003 CA-17 form also indicated that plaintiff could
    perform a number of tasks in addition to those required for the
    Automation Mail Processor position.   Specifically, plaintiff
    could climb, kneel, bend/stoop, twist, pull/push, drive a
    vehicle, operate machinery, work in temperature extremes and high
    humidity, and work with chemicals, solvents, fumes, dust, and
    noise for some or all hours during the workday.   (Id.)
    Plaintiff submitted one additional Form CA-17 to USPS on
    December 1, 2005.   (Pl. Att. 3, Aff A. p. 27 of 39 (Duty Status
    Report, signed Nov. 21, 2005, date-stamped Dec. 1, 2005).)    The
    2005 CA-17 indicates that plaintiff could return to work as of
    May 20, 2003. (Id.) The 2005 CA-17 also cleared plaintiff to lift
    20 pounds intermittently for eight hours per day, to climb,
    perform simple grasping, fine manipulation, driving a vehicle,
    operate machinery, work in temperature extremes and high
    humidity, and work with chemicals, solvents, fumes, dust, and
    noise.   (Id.)   The form contains no information regarding
    plaintiff’s ability to, inter alia, stand, sit, walk, kneel,
    twist, push, or pull.4   (Id.)
    4
    The only other evidence in the record regarding
    plaintiff’s medical condition appears in plaintiff’s EEO
    Investigative Affidavit dated June 27, 2006. The plaintiff
    describes his physical condition as of June 2006 (after the
    events at issue in his Complaint) as follows:
    My disabilities are two permanent partial impairments
    Left Foot Great Toe, Right Knee [...] severe arthritic
    condition, same as toe left foot, which affects my

    B.   Plaintiff’s Workplace Complaints
    1.   Events of 1998: Sick leave or Leave Without Pay,
    the Snow Arbitration Award.
    From approximately April through December 1998, plaintiff
    was assigned to the position of a Modified Mail Processor at the
    PD&C.    Plaintiff did not, however, work this entire time; he was
    absent from work from June 30 through July 20, 1998.     During that
    time he received payment of $1,448.83 for work related injuries
    from OWCP.    These payments were intended to cover plaintiff’s
    entire absence in June and July.       Both USPS and OWCP prohibit
    employees from receiving sick leave payments from the Postal
    Service while accepting payments from OWCP.
    Plaintiff contacted USPS on at least two occasions during
    this period to notify the Agency he would be absent from work.
    On July 5, 1998, plaintiff called in and requested 40 hours of
    leave for the week of July 5 - 11, 2008.     Plaintiff states that
    he requested leave without pay (“LWOP”) for the week, however his
    request was noted as “sick leave” on the leave slip the Postal
    Service generated for his absence.     (Pl. Att. 1, Ex. 1 (Form
    walking, running . . . I cannot work above my head and
    shoulders, walking, running I can’t run anymore, I
    can’t lift any weight greater than at least 25 pounds.
    Nor can I play Football, Basketball, swing baseball
    bats because of injuries. Walking and sitting are my
    major problems, for any extended time.
    (Pl. Att. 4 (Aff. A pp. 11-12 of 39.))
    8
    3971, Request for or Notification of Absence, Jul. 5-11, 1998).)
    Several USPS employees signed the request and John Grier, an
    Attendance Control Supervisor at the P&DC, ultimately approved
    it.   (1998 ROI p. 17, Aff. of John Grier.) Grier did not
    personally take plaintiff’s July 5, 1998 phone call. (Id.)      He
    believed that plaintiff had requested sick leave, and approved
    the request, “based on the information given on the Form 3971,
    leave slip, that was taken when [plaintiff] called in.”     (Id.)
    Plaintiff contacted USPS again to request 48 hours of leave
    without pay for the following week -- July 12 - July 19, 1998.
    (Pl’s. Att. 1. Ex. 1 (Form 3971 Jul. 12-19, 1998).) This time,
    because the USPS recorded his request as LWOP, it was routed to
    the Postal Service’s Injury Compensation office instead of
    Attendance Control.5   Injury Compensation Specialist Toni Grier
    approved plaintiff’s July 12 - 19 application for LWOP.     (Id.;
    see also 1998 ROI, p. 14, Aff. of Toni Grier.)   Toni Grier has
    handled all of plaintiff’s OWCP claims since 1997.   (Pl. Facts at
    4.)
    Plaintiff returned to work on July 22, 1998.   (Pl. Facts at
    3.)   Upon his return, plaintiff “saw the [July 5] slip[] was
    5
    Sick and annual leave is based on approval from a
    supervisor, whereas leave for a work-related injury “has to be
    either leave without pay, IOD [injured on duty] or COP
    [continuation of pay]. Those are the only . . . forms of leave
    that the injury compensation office handles.” (Def. Deposition
    Excerpts (“Def. Deps.”) Toni Grier Dep. 43-44, Mar. 28, 2008.)
    9
    wrong, [and] indicated in his own handwriting ‘comp injury’ on
    the leave slip for July 5, 1998.”      (Id.)   He did not, however,
    change the two instances on his Form 3971 which indicated that he
    had taken sick leave for that week.      (Pl. Ex. 1 (Form 3971 Jul.
    5-11, 1998).)    Plaintiff signed the July 5 leave slip on July 22,
    1998, and was paid for 40 hours of sick leave for that week.       On
    December 10, 1998, the OWCP notified plaintiff that he had been
    overpaid because he had been compensated for sick leave during
    the week of July 5, 1998 while he was also being compensated by
    OWCP.    (1998 ROI, Ex. 2, p. 26.)     Accordingly OWCP sought return
    of its money.
    Two days after returning to work, on July 24, 1998, USPS
    changed plaintiff’s job status from full-time regular to part-
    time flexible, with an effective date retroactive to April 25,
    1998.    This change in status was the result of the settlement of
    an arbitration decision (the “Snow Arbitration Award”) between
    the American Postal Workers Union (“APWU”) and USPS management.
    The settlement agreement, dated July 18, 1998, provided that all
    employees who were reassigned when they were partially recovered
    from an on-the-job injury after 1994 would be converted to part-
    time flexible employees.    Therefore, on July 24, 1998,
    plaintiff’s status was changed to part-time flexible along with
    all other employees in this group.
    10
    A few months later, the APWU and the Postal Service agreed
    to amend their settlement agreement and remove the requirement
    converting full time employees to part-time flexible status.
    Accordingly, on December 1, 1998, plaintiff was returned to full-
    time status retroactive to April 25, 1998.   Plaintiff was
    credited for any salary and leave diminutions while he was in
    part-time status.
    Plaintiff requested EEO counseling on August 31, 1998.     He
    alleged that the agency placed him on sick leave instead of LWOP
    from July 5 - 11, 1998 and changed his status from full-time to
    part-time flexible based on race, sex, age, retaliation, and
    disability discrimination.6   He filed a formal EEO complaint on
    November 2, 1999.   (1998 ROI p. 90 (Partial Acceptance/Partial
    Dismissal of a Formal Complaint, Mar. 28, 2000).)
    2.   The Events of 1999: Disputes over Sick Leave and
    Limited Duty Status.
    Plaintiff continued to work in a “limited duty” assignment
    in 1999, however, he was reassigned to work as a Mail Processor
    in the V Street Annex, Return to Sender Unit (a different
    facility than the P&DC).   Plaintiff’s new duties were described
    6
    Plaintiff previously filed several discrimination claims
    against the Postal Service regarding events not encompassed in
    this case. (Pl. Facts at 3.) Toni Grier knew about plaintiff’s
    prior complaints because he told her about them in a meeting on
    April 20, 1998. (Id.) Grier was not involved in plaintiff’s
    leave request for the week of July 5, 1998, however, nor was she
    involved in changing his job status from full-time regular to
    part-time flexible. (1998 ROI p. 14 (Aff. of T. Grier).)
    11
    as manual distribution of letters within restrictions, including:
    “no bending, twisting or stooping, no sitting longer than 15
    minutes.    Needs to sit at a low case.”   (2000 ROI p. 11 (Aff. of
    Deborah Boston (“Boston Aff.”)).)
    Plaintiff’s limited duty assignment stemmed from his on-the-
    job injury in 1997, which, as discussed above, was approved by
    OWCP and the USPS and assigned claim number XX-XXXXXXX.      In
    August 1998, plaintiff filed an additional claim with OWCP
    seeking a determination that he sustained another compensable on-
    the-job injury: a mental and emotional injury caused by stress
    due to harassment at work.   (1998 ROI, Ex. 12 p. 53 (Jun. 10,
    1999 letter from OWCP to plaintiff.))      This claim was assigned
    number 25-50529977.
    On June 10, 1999, the Department of Labor issued a ruling
    denying plaintiff’s stress and harassment claim - number 25-
    50529977.   (Id.)   The USPS Injury Compensation office received a
    copy of OWCP’s denial and, as it does with all denied claims,
    informed the appropriate operations managers of the denial.
    Specifically, on July 13, 1999, Senior Injury Compensation
    Specialist Natalia Goddard sent a memo to Operations Managers
    Darryl Martin and Edgar Gramblin entitled “Denied Claim by the
    Department of Labor”.    (Pl. Att. 11 (Jul. 13, 1999 Memorandum to
    D. Martin and E. Gramblin from N. Goddard.))     Goddard’s
    memorandum stated “the attached ruling from the Department of
    12
    Labor is provided for your information and or action . . . The
    following actions may be necessary: [...] Ensure that employee is
    not on limited duty. . . . If you have any questions please
    contact Toni Grier.”    (Id. (emphasis in original))   The
    memorandum contained no mention of plaintiff’s existing worker’s
    compensation claim for his back injury, claim number XX-XXXXXXX.
    Upon notification that plaintiff’s OWCP claim had been
    denied, Operations Manager Gramlin believed that plaintiff was
    able to perform his regular clerk duties and no longer needed
    limited duty assignment.   (Pl. Att. 1, Aff. D (Aff. of Edgar
    Gramblin, Oct. 31, 2000 (“Gramblin Aff.”)).)   Gramblin did not
    know that plaintiff had more than one OWCP claim and plaintiff
    did not immediately inform him otherwise.   Indeed, at that time
    Gramblin did not know plaintiff, nor was he aware of his previous
    EEO activity.   (Id.)
    Believing plaintiff was no longer eligible for limited duty,
    Gramblin reassigned plaintiff from his limited duty position at
    the V Street Annex to a regular duty assignment at the P&DC.
    (Id.)   Plaintiff refused to perform his regular duty assignment.
    As a result, he was suspended and advised he could provide
    information to request a light duty assignment, which employees
    may receive for non-workplace injuries.   (Id.)   After
    approximately two days, plaintiff returned with documentation to
    show he had two OWCP claims, only one of which had been denied.
    13
    He was immediately returned to his limited duty job.     Plaintiff
    filed a grievance with his union over his suspension.     He
    prevailed in his grievance, and about a month after his
    suspension, the Agency paid him for the 19.42 hours he had been
    suspended.
    Notwithstanding OWCP’s June 10, 1999 denial of plaintiff’s
    on-the-job injury related to stress (claim number 25-50529977),
    in August 1999 plaintiff submitted three requests for LWOP
    because of stress and cited the already-denied claim number –
    25-50529977.   (Pl. Att. 1, Exs. 14, 15a, 15b (Forms 3971, Aug.
    11, Aug. 12 and Aug. 13, 1999).)      None of these requests were
    approved.    (Id.)
    On September 9, 1999, plaintiff submitted a request for
    three hours of sick leave (not LWOP, as he had in August) and
    cited his other OWCP claim number - XX-XXXXXXX - which related to
    his back injury and had been approved in 1997.     This leave
    request form was initially received, as all leave slips are, by
    the USPS office of absence control.     (Pl. Att. 10 (T. Grier Dep.
    at 31.))    The absence control office routed the leave slip to the
    injury compensation office where it was handled by Toni Grier,
    who handles all injury compensation claims for employees whose
    last names begin with D through I.     (Id.)   Grier checked the
    “disapproved” box on the leave request, and wrote “no meds on
    file.”   (Pl. Att. 1, Ex. 15e (Form 3971, Sept. 12, 1999).)
    14
    However, because plaintiff requested sick leave, the Injury
    Compensation Office should not have processed the leave request
    in the first instance.   “To request sick leave, an employee
    merely had to have the leave available and make the request on
    the appropriate form . . . .   There is no requirement that any
    employee have any medical information on file in order to qualify
    for or request sick leave.”    (Pl. Opp. at 20.)   Grier admitted
    her error, explaining:   “I should never have signed the sick
    leave slip.   Sick leave . . . should be approved or disapproved
    by the supervisor, not by injury comp . . . leave for an injury
    has to be either leave without pay, IOD, or COP.    Those are the
    only [] forms of leave that the injury compensation office
    handles.”   (Def. Deps., T. Grier Dep. at 43-44; see also Pl. Ex.
    1, p. 14 (T. Grier Aff. Oct. 11, 2000) (“I do not normally take
    action on leave requests of this nature; it was an oversight that
    I did in this instance.”).)
    Once Grier had processed her “batch” of leave slips,
    including the slip for plaintiff, she “put them back in the
    envelope and sent them to Time and Attendance [or] absence
    control.    And then . . . someone else would disburse them to the
    supervisors.”   (Pl. Ex. 10, (Grier Dep. at 31-32).)   Because
    Grier denied plaintiff’s request for sick leave, the agency
    treated it as a request for annual leave.    Plaintiff did not
    have any annual leave accrued, thus, the Agency placed him in
    15
    LWOP status for three hours.    As a result, he lost three hours’
    pay.
    Plaintiff requested EEO counseling on September 28, 1999,
    alleging that both the two-day suspension in July and the sick
    leave denial in September constituted unlawful discrimination
    based on retaliation for his prior EEO activity and disability.
    He filed a formal complaint on December 14, 1999.   (1998 ROI p.
    96 (Partial Acceptance/Partial Dismissal of a Formal Complaint,
    Feb. 22, 2000).)
    On June 3, 2003, the EEO consolidated plaintiff’s two claims
    regarding the events of 1998, as set forth in Section A above,
    with his two claims regarding the events of 1999.   On March 31,
    2004, an EEO Administrative Judge (“AJ”) granted the Agency’s
    motion for summary judgment on all four of the claims, finding
    that plaintiff “failed to adduce any evidence that the conduct
    complained of was based on . . . his race, sex, age, disability
    or prior protected activity.”   (Def. Att. 2a.)   The AJ further
    found that “the Agency articulated a legitimate, non-
    discriminatory reason for its action[s],” which plaintiff “failed
    to rebut [or] . . . proffer any evidence of pretext.”   (Id.)
    USPS issued its final agency decision on May 25, 2004
    implementing the decision of the A.   (Def. Att. 2b.)   Plaintiff
    appealed to the EEO Office of Federal Operations (“OFO”).   On
    December 5, 2005, the OFO issued a decision affirming the
    16
    Agency’s final action.    The OFO found that no “reasonable fact
    finder could draw an inference of race, sex, age and disability
    determination or reprisal regarding the actions of the agency,”
    and that plaintiff “failed to present evidence that any of the
    agency’s actions were motivated by discriminatory animus toward
    [plaintiff’s] protected classes.”      (Def. Att. 3, p. 6.)
    3.   The Events of 2000: May 3, 2000 Overtime Dispute.
    Plaintiff’s complaint contains one allegation of unlawful
    treatment in 2000: denial of an overtime opportunity on May 3,
    2000.
    The Postal Service awards overtime “when employees are
    needed to work before or after their work schedule and also when
    employees are needed to work on the[ir] non-schedule[d] workdays
    based on the mail volume.”    (Pl. Att. 2, Aff. C (Aff. of William
    Darryl Martin (“Martin Aff.”).) Employees desiring to work
    overtime put their names on a voluntary ‘overtime desired’ list.
    (Id.)    When overtime is necessary, management reviews the
    overtime desired list and schedules overtime “among qualified
    employees doing similar work in the work location where the
    employees normally work.”    (2000 ROI Ex. 7b, p. 41 (Collective
    Bargaining Agreement Between the USPS and the American Postal
    Workers Union, AFL-CIO, Article 8.5).)     In the Washington, D.C.
    area, employees may sign an overtime desired list to work on
    their non-scheduled workdays as well as their scheduled workdays.
    17
    (Martin Aff.; see also Pl. Att. 6 (Local Mem. of Understanding
    Between the Washington, D.C. Post Office, Air Mail Center, and
    American Postal Workers Union AFL-CIO).)   However, “those absent
    or on leave shall be passed over.”   (2000 ROI Ex. 7b, p. 41.)
    Limited duty employees such as plaintiff are not precluded
    from working overtime.   (Martin Aff.)   However, in order to be
    “qualified” to perform the overtime as set forth in the
    Collective Bargaining Agreement, “the employee must be able to
    perform the duties in the operation where the overtime is
    required.   If the limited duty employee can work in automation he
    will be allowed to work any overtime called in automation . . .
    if he is on the overtime desired list for automation but he/she
    is physically unable to perform the duties on automation he would
    not be selected for overtime in automation.”   (Id.)
    In the spring of 2000, plaintiff was still working in the
    return-to-sender unit under the direct supervision of Deborah
    Boston.   William Darryl Martin was the Senior Manager for
    Distribution Operations.   Plaintiff put his name on overtime
    desired lists for both his scheduled and non-scheduled days, to
    perform any work for which he was qualified in his location.
    (Def. Deps., Keith Diggs Dep. at 55.)
    The return-to-sender unit moved from the V Street Annex to
    the P&DC during the first week in May, 2000.   (2000 ROI Aff B.
    (Boston Aff.).)   On Wednesday, May 3, 2000 plaintiff worked from
    18
    4:00 p.m. until 10:00 p.m.   He took annual leave for the hours he
    did not work.   Wednesdays were one of plaintiff’s regularly
    scheduled workdays; his regularly scheduled hours were 4:00 p.m.
    to midnight.    (2000 ROI Ex. 3, p. 19 (Limited Duty Job Offer Dec.
    19, 1998); Ex. 1, p. 17 (Time Summary).) Plaintiff was not
    offered overtime on May 3, 2000, nor was overtime awarded in the
    return-to-sender unit on that day.
    Plaintiff sought EEO counseling to complain that he was
    unlawfully denied overtime based on race and disability.    (ROI
    2000 p. 55 (EEO Counselor’s Report Jun. 13, 2000).)   He filed a
    formal complaint alleging race and disability discrimination on
    October 3, 2000 (2000 ROI p. 52 (EEO Complaint of Discrimination
    in the Postal Service, Oct. 3, 2000).)   In the investigative
    affidavit he provided to the EEO, plaintiff alleges employees in
    Operations 030, 040 and 150 at the P&DC – only 100 feet from his
    work location once the return-to-sender unit moved to the P&DC
    facility – performed overtime work that “was within [his]
    physical restrictions . . . [he] could have performed the work in
    overtime status.”7 (2000 ROI Aff A., p. 8, (Diggs Aff. Mar. 1,
    2001).) In response, manager Boston explained to the EEO
    Counselor that during the approximately five years she supervised
    7
    The numbers 030, 040 and 150 refer to pay locations.
    Plaintiff worked in pay location 396. The parties point to no
    evidence in the record, and this Court is unable to find any,
    specifying the type of work performed at pay locations 030, 040
    and 150.
    19
    the return-to-sender unit, “there was no overtime given to the
    employees [in the return to sender unit] . . . because of the low
    priority of the mail that was being worked . . . It did not
    warrant paying employees premium overtime pay to process it.”
    (Boston Aff.)   She also asserted that plaintiff would not have
    been able to work overtime outside the return to sender unit
    because “his physical limitations would not allow him to work in
    other sections.”   (Id.)
    An EEO AJ heard plaintiff’s formal complaint.    She found
    that no discrimination occurred, and dismissed the claim on
    September 3, 2003.   (Def. Att. 4.)   On September 17, 2003, the
    Postal Service issued a final order implementing the AJ’s
    decision, which plaintiff appealed to the EEO’s OFO.     (Def. Att.
    5.)   The OFO issued a decision on March 3, 2005, which found that
    there was no “overtime available within [plaintiff’s] pay
    location” on May 3, 2000, and that “even if there was overtime
    available on the day in question, [plaintiff] was on annual
    leave, and therefore ineligible for overtime.”   (Id.)    The OFO
    upheld the A’s decision and the Postal Service’s final order that
    “construing the evidence to be most favorable to [plaintiff] . .
    . [plaintiff] failed to present evidence” that his failure to
    receive overtime was “motivated by discriminatory animus toward
    [his] protected classes.”   (Id.)
    20
    4.    The Events of January 2002 - February 2006:
    Plaintiff’s Departure and Ultimate Removal from
    the Postal Service.
    In 2001, the P&DC (also known as “Brentwood”) was targeted
    in an anthrax terrorist attack.     As a result, the Post Office
    closed the P&DC in October 2001, and its employees were
    transferred to other postal facilities.     (Pl. Att. 10, Grier Dep.
    83.)    Plaintiff was reassigned to the Calvert Development and
    Design Center for a short time following the anthrax attack.
    (Id. at 84.)      There was no work, however, for plaintiff to
    perform.    Plaintiff and at least 30 other relocated employees
    “sat in a room . . . [doing] nothing.”     (Id. 83-84.)   In January
    2002, Postal Service management decided that plaintiff and these
    other employees for whom the Agency had no work should be sent
    home.
    On January 23, 2002, Julie E. Szarek, USPS Human Resources
    Manager, sent plaintiff a letter stating, in relevant part:
    Due to the closure of the Brentwood facility and its
    relocation to other offices, Plant Operations has
    indicated it is no longer able to accommodate your
    restrictions. Effective Friday, January 25, 2002, you
    should no longer report to the Calvert worksite.
    Since the agency cannot provide suitable duties within
    your restrictions, the injury compensation office is
    issuing CA-7 forms for your use. This form should be
    completed and submitted to this office to ensure that
    you are compensated through the Department of Labor,
    Office of Worker’s Compensation Programs.
    If you have further concerns please contact Toni Grier,
    Manager, Injury Compensation, at [phone number].
    21
    (Pl. Att. 3, p. 4 (Letter from J. Szarek to K. Diggs, Jan. 23,
    2002).)      As indicated by Szarek’s letter, the CA-7 form is used
    by the Department of Labor OWCP to process Claims for
    Compensation due to, in this case, medical restrictions that
    precluded the USPS from finding suitable work for plaintiff.
    Plaintiff was among a group of “30 people or more . . . who were
    sent home and given CA-7s to complete and be compensated through
    the [OWCP] until the agency was able to provide them with work.”
    (Pl. Att. 10 (Grier Dep. 83-84).)        The letter instructs plaintiff
    to file his CA-7 forms with “this office” – the injury
    compensation office.      (Id. at 91-93.)
    The record contains no Form CA-7s for plaintiff between
    January 2002 and May 2003.      Plaintiff “turned in the CA-7s –
    which [USPS] say[s] they never received – to get paid.       I didn’t
    get paid.”      (Diggs Dep. 64.)   The Injury Compensation office did
    not receive any CA-7s from plaintiff.       (Pl. Att. 10 (Grier Dep.
    91).)
    On January 23, 2003, Helen T. Jackson, Attendance Control
    Supervisor for Tour 3,8 sent plaintiff a memorandum via certified
    mail.       The memorandum states, in relevant part:
    8
    “Tour” is another word for shift. At all times relevant
    in this action, plaintiff was assigned to Tour 3 (sometimes
    referred to as Tour III), which is 4:00 p.m. to midnight. (2000
    ROI Exs. 3-4, pp. 19-20 (Limited Duty Job Offers Apr. and Dec.
    1998).)
    22
    A review of your record reflects an unsubstantiated
    absence from duty. Therefore, you are instructed to
    submit the following documents within five calendar
    days of the receipt of this letter:
    •    PS Form 3971 (Request for or Notification of
    Absence) and
    •    Medical Certificate covering your absence from
    the beginning through the present.
    The Medical Certificate must provide an explanation
    of the nature of your illness sufficient to indicate
    you have been, or will be, unable to perform your
    normal duties for the time period of your absence . . .
    In addition, you are instructed to submit a PS Form
    3971 and a Medical Certificate every thirty days that
    you are absent thereafter to your supervisor at the
    address listed below:
    Southern Maryland Processing & Dist. Ctr.
    Deborah I. Boston, ACS, Tour 3
    [Address]
    If you fail to provide the required documentation
    and/or fail to respond to this notice as outlined
    above within five calendar[] days, the absence will
    be charged to AWOL. AWOL MAY RESULT IN DISCIPLINARY
    ACTION, UP TO AND INCLUDING REMOVAL FROM THE POSTAL
    SERVICE.
    (Pl. Att. 3 (Jan. 27, 2003 letter from H. Jackson to K.
    Diggs)(emphasis in original).)
    Plaintiff did not provide his supervisor with the
    information requested in the January 23, 2003 letter.    Instead,
    he sought EEO counseling on January 29, 2003.   Plaintiff claimed
    that he “was the only person from [the] Tour 3 injured section to
    receive such a letter,” and accused the Postal Service of
    retaliation based on his prior EEO activity.    (Def. Att. 12
    (Information for Pre-Complaint Counseling).) Plaintiff and the
    23
    Postal Service entered into a settlement on March 7, 2003,
    resolving his claim.   The settlement states, in relevant part:
    (1)   [Plaintiff] shall provide to Injury Compensation
    [address], to the attention of Ms. Toni Grier,
    copies of documentation relating to the CA-7's
    filed following January 25, 2002, the date he was
    sent home following the unavailability of work. . .
    (2)   [Plaintiff] shall also provide written notice to
    Ms. Grier of his doctor’s appointment to have his
    medical restrictions updated.
    (3)   Ms. Grier shall contact [plaintiff’s] assigned
    office to have a CA-17 sent to him for submission to
    the medical provider at the scheduled appointment.
    (4)   Items 1-3 shall be completed by March 14, 2003.
    (5)   [Plaintiff] shall provide Ms. Grier with an updated CA-
    17 following his doctor’s appointment. This letter
    shall be accompanied by a letter of job
    responsibilities that he feels he can perform in
    accordance with his restrictions.
    (Pl. Att. 3, p. 9-11 (Settlement Agreement Mar. 7, 2003).)
    Plaintiff failed to meet the March 14, 2003 deadline.     He
    “attempted to confer with [] Grier . . . to inform [her] that he
    could not meet the provisions of . . . the Agreement on time, but
    he could not reach her.”   (Pl. Facts at 2.)   Plaintiff eventually
    submitted a Form CA-17 dated May 20, 2003 to the EEOC office, but
    not to Grier or the Injury Compensation Office as required by
    paragraph (5) of the settlement agreement.     He also failed to
    submit copies of the CA-7s to either the EEOC office or the
    Injury Compensation Office, as required by paragraph (1).
    24
    On April 17, 2003, plaintiff filed a timely EEO Complaint
    alleging that the Agency breached paragraph (3) of the settlement
    agreement by not contacting him before March 14, 2003.    The
    Agency issued a final decision denying the breach-of-contract
    claim on October 29, 2004.   (Def. Att. 6.)    Plaintiff appealed
    the final agency decision to EEO’s OFO, which issued its decision
    on April 27, 2005.   The EEO found that the Postal Service “had
    not breached the agreement because its own actions were
    contingent on [plaintiff] first taking certain actions of his
    own,” namely, sending CA-7s to Grier as required by paragraph (1)
    of the settlement agreement, and providing Grier with written
    notice of his doctor’s appointment as required by paragraph (2).
    (Def. Att. 7.)   The EEO further found that plaintiff breached
    paragraph (5) of the agreement by sending his CA-17 to the EEO
    office, not “to the Injury Compensation office, as explicitly
    stated in the settlement agreement.”   (Id.)
    The next correspondence between plaintiff and the Postal
    Service did not occur until September 27, 2004.    During that
    time, following the expiration of his state unemployment benefits
    in early 2003, plaintiff had obtained employment as a delivery
    driver for “My Florist, Exclusively Roses,” and delivered floral
    arrangements.    At some point thereafter, plaintiff left the
    florist position for a “better job” working for “Liberty
    Transportation Incorporated” as a “yard jockey” and remained
    25
    there until May 31, 2007 when the company relocated.9   (Diggs
    Dep. 71-72.)
    On September 27, 2004, Helen Jackson-Baker (formerly Helen
    Jackson), the attendance control supervisor for Tour 3, sent
    plaintiff another letter.   She acknowledged that plaintiff had
    been sent home on January 23, 2002, and that the Agency’s action
    was the genesis of his absence from work.   (Pl. Att. 3, p. 6
    (Sept. 27, 2004 Letter from H. Jackson-Baker to Plaintiff).)     The
    letter explained:
    Since the agency could not provide suitable duties
    within your restrictions, the Injury Compensation
    Office issued CA-7 forms for your use. The form
    should have been completed and submitted to that
    office to insure that you were compensated through
    the Department of Labor, Office of Workers’
    Compensation Programs.
    The Injury Compensation Office indicated that you
    currently do not have an active open claim. There
    are no records indicating that you requested
    compensation from the Department of Labor. All of
    the employees who submitted claims for compensation
    due to ‘no available work’ were compensated through
    the Department of Labor.
    You have an obligation to notify your employer of your
    status. Failure to do so puts you in AWOL status.
    It is incumbent upon you to submit acceptable evidence
    to cover your absence from January 25, 2002 through
    your return to duty . . . [Y]ou are to submit supporting
    ACCEPTABLE EVIDENCE showing why you are unable to

    Plaintiff explains that: “[a] yard jockey is the tractor
    [that] hooks up to loaded trailers, puts them to the dock, and
    then they unload them. Then he comes back, gets the unloaded
    trailer, puts it back in the lot. That’s what I did all day
    long. I was moving trailers back and forth.” (Id.)

    report, within five (5) calendar days from the date of
    receipt of this letter, and for every thirty (30) days
    thereafter that you are absent from duty.
    HELEN JACKSON-BAKER, ACS, Tour 3
    [Address]
    Acceptable evidence for medical reasons is defined as
    medical documentation signed and furnished by your
    attending physician or other attending practitioner.
    The documentation must provide an explanation of the
    nature of the illness or injury causing your absence
    from work . . .
    Should you fail to comply with these instructions, you
    will be considered in an Absence Without Official Leave
    Status since January 25, 2002 and action may be taken
    to remove you from the United States Postal Service.
    (Id. (emphasis in original).)
    By letter dated October 7, 2004, plaintiff responded to
    Jackson-Baker, stating that “my absence from the Postal Service
    is not directly related to Illness or Injury, my absence is
    directly related to Toni Grier, Compensation Unit.   Ms. Grier has
    not abided by the [settlement] agreement.”   (2006 ROI (Pl. Aff.
    A, p. 31 of 39 (emphasis in original)).)   Plaintiff attached a
    copy of the January 25, 2002 letter from the Postal Service and a
    copy of the March 7, 2003 settlement agreement to his letter.
    (Pl. Att. 4, (Pl. Aff. A., p. 9 of 39).)   He did not send medical
    documentation.   (Id.)
    Jackson-Baker replied to plaintiff on October 20, 2004.      She
    wrote:
    You have not been to work since January 23, 2002
    nor have you sent any documentation to substantiate
    27
    your absence. You are required to submit acceptable
    documentation immediately and every thirty (30) days
    until your return to duty.
    If documentation is not sent by October 27, 2004 and
    you do not respond to the letter sent to you, the next
    step may be taken to remove you from the Postal Service.
    This letter is being sent to you to afford you the
    opportunity to come in for a Pre-Disciplinary Interview.
    This interview gives you the chance to tell ‘your side
    of the story’.
    The interview is being set up for October 29, 2004 at
    the [...] P&DC.
    (2006 ROI Aff. A, p. 32 of 39 (Oct. 20, 2004 Letter from H.
    Jackson-Baker to plaintiff).)
    Plaintiff met with Jackson-Baker at the P&DC.    He “went over
    verbally with [] Baker all of the evidence [he] submitted,”
    namely, the January 25, 2002 letter and the 2003 mediation
    agreement. (Pl. Att. 4 (Aff. A., p. 9 of 39).)   Plaintiff
    “awaited further response,” but “received no further input about
    this matter.”   (Id.)
    In May 2005, the Post Office again requested that plaintiff
    provide medical documentation addressing his ability to work
    between 2002 and “the present”.    (2006 ROI, Ex. 7 (Letter to
    plaintiff from F. Mitchell, absence control office supervisor,
    Tour 3 dated May 19, 2005.))    Like the previous letters from
    Baker-Jackson, the May 2005 letter from Mitchell requested past
    and present medical information and updates every 30 days
    thereafter, and closed with the warning that if plaintiff did not
    28
    promptly respond, “the absence will be charged to AWOL. AWOL MAY
    RESULT IN DISCIPLINARY ACTION, UP TO AND INCLUDING REMOVAL FROM
    THE POSTAL SERVICE.” (Id.) (emphasis in original.)
    Hearing no response from plaintiff, Mitchell (sometimes
    referred to as “Bears-Mitchell”) sent plaintiff a notice of
    another pre-disciplinary interview.   (2006 ROI Ex. 8 (Letter to
    plaintiff from F. Bears-Mitchell dated June 16, 2005.))
    Mitchell’s letter states in relevant part: “Discipline is being
    considered.   However, during the interview, you will be given the
    opportunity to tell your side of the story relative to why you
    did not respond to my notice for you to support your absence with
    documentation and any other information you wish to share that
    might prevent disciplinary action.”   (Id.)   Bears-Mitchell,
    plaintiff, and plaintiff’s union shop steward met for the pre-
    disciplinary interview on June 24, 2005.   During the interview,
    plaintiff told Bears-Mitchell about his prior EEO activity.     (Pl.
    Att. 4 (Aff. A. p. 10 of 39).)   He also discussed his then-
    current employment driving a tractor-trailer for Liberty
    Transportation.   (Id.)   Plaintiff did not provide documentation
    regarding his medical restrictions during the period of May 20,
    2003 to June 2005 at or prior to the interview.   He told Bears-
    Mitchell that he “is ready to come back to work,” asked “what
    medical document is needed to return to work,” requested that the
    Postal Service “mail it” to him, and stated that he “is working
    29
    now.”    (2006 ROI Ex. 9 (Mitchell’s notes of Pre-Disciplinary
    Interview Jun. 24, 2005).)
    Bears-Mitchell did not receive the requested medical
    documentation from plaintiff.    (Def. Deps. (Bears-Mitchell Dep.
    116).)    On October 25, 2005, she wrote to plaintiff again,
    explaining “our records do not indicate that you are unable to
    perform work.    Therefore you are instructed to report for duty as
    scheduled or provide acceptable medical evidence that denotes
    your inability to work . . . You are being allotted five (5) days
    from the receipt of this letter to respond.    Failure to [respond]
    will result in corrective action up to and including removal from
    the Postal Service.”    (2006 ROI Ex. 10 (Oct. 25, 2005 Letter from
    Bears-Mitchell to Plaintiff).)    Plaintiff did not respond to the
    letter.    Instead, he wrote a letter dated November 9, 2009 to his
    shop steward, acknowledging receipt of the October 25, 2005
    letter and advising that he was filing a grievance with his
    union.    (2006 ROI (Aff. A., p. 39 of 39).)
    On December 1, 2005, plaintiff delivered one Form CA-17 to
    the USPS’ Medical Unit.    (Pl’s. Att. 3 (Aff. A. 15 of 39 and 27
    of 39).) The CA-17 form, dated November 21, 2005, indicates that
    plaintiff’s health practitioner advised him to return to work,
    with restrictions, as of May 20, 2003.    (Id.)
    By letter dated January 12, 2006, Mitchell advised plaintiff
    she was “in the process of determining what, if any,
    30
    administrative action shall be taken in regard to your current
    work status.”   (2006 ROI Ex. 12.)      Mitchell directed plaintiff to
    report for a pre-disciplinary interview on January 18, 2006, and
    advised plaintiff that his “failure to report . . . will result
    in [Mitchell] making a decision without any input [plaintiff] may
    have to offer for [] consideration.”      (Id.)
    Plaintiff, his union shop steward and Mitchell met for the
    pre-disciplinary interview as scheduled.      In her notes of the
    meeting, Mitchell listed among the “Nature of Infractions” to be
    discussed as “(1) unacceptable medical documentation; (2) where
    have you been since 2003".    (2006 ROI Ex. 13 (F. Mitchell’s Pre-
    Disciplinary Interview notes, Jan. 18, 2006).)      Mitchell’s notes
    also recount plaintiff’s answers.       In response to question (1)
    plaintiff stated “every time he goes to the doctor there’s a co-
    payment,” and he “did not know” the USPS wanted documentation of
    his “diagnosis and prognosis.”10     (Id.)   In response to question
    (2), he “was sent home because there was no work for him” in
    2002, and he never received “anything in writing telling him to
    come back to work.”   (Id.)   Plaintiff also “explained in detail
    about [his] EEO cases . . . and also the fact of [his] employment
    elsewhere.”   (Pl. Att. 4, (Aff. A. p. 10 of 39).)     Plaintiff did
    10
    Mitchell explains “prognosis and diagnosis . . . might
    state that Mitchell was seen in my office on so and so date for a
    broken leg; therefore, her expected return time to work might be
    three months . . . It might say anything like that. It’s just a
    prescription pad.” (Pl. Att. 9 (Mitchell Dep. p. 147).)
    31
    not, however, provide any medical documentation at the Pre-
    Disciplinary Interview.
    Mitchell recommended plaintiff’s removal from the Postal
    Service in a letter to Labor Relations dated February 1, 2006.
    (ROI 2006, Aff. C p. 9 of 9.) Mitchell advised removal “for the
    following reason.” (Id.)   Her letter goes on:
    Mr. Diggs was absent without approved leave (AWOL)
    from May 20, 2003 until June 24, 2005. He has not
    provided us with acceptable medical documentation.
    He was given a Pre-Disciplinary Interview on January
    18, 2006, [during] which [Mitchell] informed him of
    his unacceptable medical documentation. To this date
    [Mitchell has received] no response.
    (Id.)   John W. Cooke, Distribution Operations Manager, concurred
    with Mitchell’s recommendation.    (Id.)
    The Postal Service issued plaintiff a Notice of Removal
    based on the “charge” of “absence without leave” dated February
    21, 2006.   He was terminated effective March 31, 2006.   The
    Notice of Removal states, in relevant part, “a review of your
    attendance record from May 20, 2003 through June 24, 2005
    reflects your unscheduled absence from work and failure to
    provide acceptable documentation to justify your absence.
    Accordingly, you have been charged with Absence Without Official
    Leave (AWOL).”   (2006 ROI Ex. 14.)
    On May 19, 2006, plaintiff filed an EEO complaint alleging
    that his January 18, 2006 pre-disciplinary interview and
    subsequent removal constituted discrimination based on sex, age,
    32
    physical disability, and retaliation.   (Compl. ¶ 10a.)   Plaintiff
    had originally requested that an AJ hear his formal EEO
    complaint, but on March 7, 2007, he chose instead to add the
    allegations in his 2006 EEO complaint to the instant case, which
    was already pending before this Court. (Def. Att. 9 (Amended
    Notice of Intention to File Suit).)    The following week, on March
    14, 2007, the EEO dismissed his complaint and remanded it to the
    Postal Service for the issuance of a final agency decision. (Def.
    Att. 8a.)   On April 1, 2007, the agency issued its final agency
    decision, which found that plaintiff “failed to establish that
    [he was] subjected to sex, age, disability or retaliation
    discrimination,” that “the Agency met its burden of demonstrating
    legitimate, non-discriminatory reason for the actions it took,”
    and that plaintiff “failed to show these reasons were pretext for
    intentional discrimination.”   (Id.)
    II.   STANDARD OF REVIEW
    Under Federal Rule of Civil Procedure 56, a motion for
    summary judgment shall be granted if the pleadings, depositions,
    answers to interrogatories, admissions on file and affidavits
    show that there is no genuine issue of material fact, and that
    the moving party is entitled to judgment as a matter of law.
    Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 246 (1986).     To be
    material, the factual assertion must be capable of affecting the
    outcome of the litigation; to be genuine, the issue must be
    33
    supported by sufficient admissible evidence that a reasonable
    fact finder could find for the nonmoving party.      Anderson, 
    477 U.S. at 248
    ; see also Lanningham v. U.S. Navy, 
    813 F.2d 1236
    ,
    1242-43 (D.C. Cir. 1987).
    In determining whether a genuine issue of material fact
    exists, the Court must view all facts in the light most favorable
    to the non-moving party.     See Matsuhita Elec. Indus. Co. v.
    Zenith Radio Corp., 
    475 U.S. 574
    , 587 (1996).      The non-moving
    party’s opposition, however, must consist of more than mere
    unsupported allegations or denials and must be supported by
    affidavits or other competent evidence setting forth specific
    facts showing that there is a genuine, material issue for trial.
    Fed. R. Civ. P. 56(e); see Celotex Corp. v. Cattrett, 
    477 U.S. 317
    , 322 (1986).
    III. ANALYSIS
    A.   Discrimination and Retaliation Claims
    In his second amended complaint, plaintiff claims he
    suffered eight adverse actions which he presented in his
    underlying EEO complaints.    (See generally Second Amended
    Complaint “Compl.”)   Plaintiff alleges that the Postal Service
    discriminated against him based on race, age, sex, disability,
    and/or retaliated against him by:
    (1)   changing plaintiff’s request for leave without pay to sick
    leave (Compl. ¶ 17);
    34
    (2)   changing plaintiff’s job duty status from full-time regular
    to part-time flexible (id. ¶ 18);
    (3)   denying plaintiff’s request for sick leave, resulting in
    plaintiff taking leave without pay (id. ¶ 19);
    (4)   denying plaintiff a limited duty assignment, which caused
    him to be suspended for 19.42 hours (id. ¶¶ 22-23);
    (5)   denying plaintiff overtime (id. ¶¶ 24-26);
    (6)   denying plaintiff discovery in his administrative complaints
    (id. ¶ 10);
    (7)   conducting a pre-disciplinary interview of plaintiff in June
    2005 (id. ¶ 31); and,
    (8)   removing plaintiff from the Postal Service. (id. ¶ 39.)
    Defendant argues that some of these actions were not
    adverse, and also offers legitimate, non-retaliatory explanations
    for its actions.   The Court finds that some of the challenged
    actions were not adverse or materially adverse, and further finds
    that plaintiff failed to show defendant’s explanations for its
    adverse actions were pretexts for discrimination or retaliation.
    Accordingly, the Court grants summary judgment for the defendant
    based on plaintiff’s discrimination and retaliation claims.
    1.   Governing Law
    Under Title VII, the ADEA, and the Rehabilitation Act, the
    two essential elements of a discrimination claim are that (I) the
    plaintiff suffered an adverse employment action (ii) because of
    the plaintiff's race, sex, age, or disability. See 42 U.S.C. §
    2000e-16(a); 29 U.S.C.§§ 621 et seq.; 
    29 U.S.C. §§ 701
     et seq.;
    Adeyemi v. District of Columbia, 
    525 F.3d 1222
    , 1226 (D.C. Cir.
    35
    2008); Brady v. Office of Sergeant at Arms, 
    520 F.3d 490
    , 493
    (D.C. Cir. 2008); see also Brown v. Brody, 
    199 F.3d 446
    , 455
    (D.C. Cir. 1999) (race discrimination under Title VII); Barnette
    v. Chertoff, 
    453 F.3d 513
    , 515 (D.C. Cir. 2006) (age
    discrimination under the ADEA); Breen v. Dep’t of Transp., 
    282 F.3d 839
    , 841 (D.C. Cir. 2002) (disability discrimination under
    the Rehabilitation Act).   “A plaintiff must prove both elements
    to sustain a discrimination claim.”     Baloch v. Kempthorne, 
    550 F.3d 1191
    , 1196 (D.C. Cir. 2008).     To prove retaliation under
    these statutes, the plaintiff generally must establish that he
    suffered (I) a materially adverse action (ii) because he or she
    had brought or threatened to bring a discrimination claim.      See
    
    id.
     at 1198 (citing 42 U.S.C. § 2000e-3(a); 
    29 U.S.C. §§ 621
     et
    seq.; 
    29 U.S.C. §§ 701
     et seq.; Burlington N. & Santa Fe Ry. Co.
    v. White, 
    548 U.S. 53
    , 68 (2006)).     Although the tests for
    proving discrimination and retaliation both contain the term
    ‘adverse action,’ “the concept [] in the retaliation context is
    broader than in the discrimination context, and can encompass
    harms unrelated to employment or the workplace ‘so long as a
    reasonable employee would have found the challenged action
    materially adverse.’”   Franklin, 
    600 F. Supp. 2d at
    66 (citing
    Baloch, 
    550 F.3d at
    1198 n.4).
    Traditionally, courts have analyzed discrimination and
    retaliation claims under Title VII, the ADEA, and the
    36
    Rehabilitation Act using the three-step burden shifting framework
    set forth in McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
    (1973).   However, where an employer has asserted legitimate, non-
    discriminatory reasons for the actions being challenged,
    the district court need not – and should not – decide
    whether the plaintiff actually made out a prima facie
    case under McDonnell Douglas. Rather, in considering
    an employer’s motion for summary judgment . . . the
    district court must resolve one central question: Has
    the employee produced sufficient evidence for a
    reasonable jury to find that the employer’s asserted
    non-discriminatory reason was not the actual reason and
    that the employer intentionally discriminated against
    the employee on the basis of race, color, religion,
    sex, or national origin?
    Brady, 
    520 F.3d at 494
     (citation omitted; emphasis in original).
    This framework applies to discrimination    claims under Title VII,
    the ADEA, and the Rehabilitation Act.11    See, e.g., Baloch, 
    550 F.3d at
    1197 n.2, 1200 (applying Brady principle to Title VII and
    ADEA discrimination claims); Kersey, 586 F.3d at 17 n.1-2 (Brady
    analysis applies to discrimination claims under the
    11
    In its motion for summary judgement Defendant argues that
    plaintiff does not have a disability as defined by the
    Rehabilitation Act. (Def. Mem. at 18-22.) Defendant further
    argues that the Court should apply the standard for determining
    disability as it existed before the ADA Amendments Act of 2008.
    (Id.) The Court concludes that it need not consider these issues
    in this case. As this Circuit recently explained, once the
    defendant has proffered a nondiscriminatory and non-retaliatory
    rationale “it is unnecessary to consider whether the plaintiff
    has actually made out the elements of a prima facie case” of
    discrimination or retaliation based on disability. Kersey v.
    Washington Metro. Transit Auth., 
    586 F.3d 13
    , 17 n.1-2 (D.C. Cir.
    2009). As discussed throughout, the Postal Service has proffered
    these rationales; accordingly, the Court need not consider
    whether plaintiff is, in fact, disabled.
    37
    Rehabilitation Act.)     The Brady framework also applies to
    retaliation claims under these statutes.      Baloch, 
    550 F.3d at
    1197 n.2, 1200; Kersey, 
    586 F.3d at 17, n.1-2
    .      Thus, where the
    employer has proffered a legitimate, non-retaliatory reason for a
    materially adverse action, the Court makes the same functional
    inquiry as it does in a discrimination claim: “whether plaintiff
    has produced sufficient evidence for a reasonable jury to find
    that the employer’s asserted non-retaliatory reason was merely a
    pretext for retaliating against the employee for his prior
    opposition to an unlawful employment action.”      Franklin, 660 F.
    Supp. 2d at 66.
    2.      The Challenged Actions
    (I)       Leave Request for the Week of July 5,
    1998
    Plaintiff contends that the Postal Service discriminated
    against him on the basis of race, sex, age, and disability, when
    “his request for sick leave was changed to LWOP for the week of
    July 5-12, 1998.”12     (Pl. Opp. at 19.)   Defendant has proffered a
    legitimate, non-discriminatory reason for the challenged action
    12
    In his complaint, plaintiff appeared to allege that the
    Agency’s designation of his leave request as sick leave was also
    retaliatory. (Compl. ¶ 17.) However, in his opposition, he
    fails to respond to defendant’s argument as to this issue. (See
    Pl. Opp. at 1-2, 19.) It is therefore proper to treat
    defendant’s argument as conceded. See Sewell v. Chao, 
    532 F. Supp. 2d 126
    , 136 n.5 (citations omitted), aff’d Slip Copy, No.
    08-5079, 
    2009 WL 585660
     (D.C. Cir. Feb. 25, 2009).
    38
    and disputes “both the existence of an adverse action and whether
    the action occurred because of discrimination.” Franklin, 
    600 F. Supp. 2d at 63
     (emphasis in original).    “In such instances,
    courts may first determine the existence of an adverse action.”
    
    Id.
     (citing Baloch, 
    550 F.3d. at 1196-97
    ).
    An “employment decision does not rise to the level of an
    actionable adverse action” sufficient to sustain a discrimination
    claim “unless there is a tangible change in the duties or working
    conditions constituting a material employment disadvantage.”
    Stewart v. Lewis, 
    275 F.3d 1126
    , 1134 (D.C. Cir. 2002)(internal
    citations omitted).     Defendant argues that plaintiff was
    initially paid twice for his week of leave from July 5 - 12,
    1998: once by the USPS for 40 hours of sick leave and once by
    OWCP for disability leave during the same time period.    (Def.
    Mem. at 9-10.)    Thus, the Agency argues, plaintiff “initially
    received a windfall” by getting two paychecks for the same time
    period.    (Id.; see also Def. Reply at 10.)   Eventually OWCP sent
    him a notice of overpayment and he was required to return the
    money he received from OWCP; however, he kept his paycheck from
    USPS.    Because Plaintiff received full pay for the week of leave,
    the Agency argues, he did not suffer an adverse action.
    Plaintiff concedes that he did not lose pay for the week, but
    argues that his “leave balance was affected as a result of the
    39
    [Agency’s] conduct,” and the impact on his leave balance
    “constitutes an adverse action.”      (Pl. Opp. at 19.)
    The Court is not persuaded that plaintiff suffered an
    adverse employment action.    Plaintiff cites no case law, and the
    Court is not aware of any, that processing an employee’s leave
    request where the only consequence was that he had to take sick
    leave instead of workers compensation leave, constitutes an
    adverse employment action.    But cf. Kline v. Springer, 
    602 F. Supp. 2d 234
    , 243 (D.D.C. 2009) (changes to leave balance not
    adverse action “where the only consequence was that plaintiff had
    to use annual leave instead of sick leave on, at most, two
    occasions”).
    Even assuming the existence of an adverse action, plaintiff
    has not “produced sufficient evidence for a reasonable jury to
    find that the employer’s asserted non-discriminatory reason” for
    treating plaintiff’s leave request as one for sick leave “was not
    the actual reason and that the employer intentionally
    discriminated against” him.    Brady, 
    520 F.3d at 494
    .    The
    plaintiff theorizes that John Grier or Toni Grier deliberately
    tampered with his leave request for the week of July 5-12, 1998,
    changing it from a request for LWOP to a request for sick leave.
    (Compl. ¶ 17; Pl. Facts at 3.)   Toni Grier, however, denies any
    involvement in receiving, processing or approving his claim for
    that week.   (Pl. Att. 1, p. 14 (T. Grier Aff.).)    John Grier also
    40
    denies that he was responsible for any changes to plaintiff’s
    leave request.    He states that he did not take plaintiff’s
    telephone call in which he requested leave for the week of July
    5; another employee in the absence control unit took the call and
    recorded plaintiff’s request as one for sick leave.     (Pl’s Att.
    1, p. 17 (John Grier Aff.).)    Grier’s “approval of the request
    was based on the information given on the Form 3971, leave slip,
    that was taken when he called in.”     (Id.)   John Grier also points
    out that plaintiff signed the leave slip, which clearly stated
    that he had been approved for 40 hours of sick leave.     (Id.)    In
    other words, the USPS asserts that it processed plaintiff’s leave
    request as a request for sick leave because its manager believed
    plaintiff asked to be granted sick leave, and because plaintiff
    did nothing to disabuse him of that belief.
    Plaintiff has provided no evidence that either John Grier or
    Toni Grier was responsible for any unauthorized change to his
    July 5 - 12 leave request.    The evidence is uncontroverted that
    he signed the slip without changing the leave designation, nor
    did he “bring any discrepancy on the Form 3971 to his
    supervisor’s attention prior to signing the document.”     (Def.
    Mem. at 29; see also Def. Mem. at 9, Def. Reply at 10.)     He also
    concedes that both John and Toni Grier were involved with the
    accurate processing of his leave request for LWOP the following
    week.    (See Pl. Opp. at 19.) In short, plaintiff “has produced no
    41
    direct evidence of discriminatory animus by the decision maker
    and failed to produce any other evidence that discredits the
    underlying reason for” the Agency’s treatment of his leave
    request as a request for sick leave.     Baloch, 
    550 F.3d at 1198
    .
    “Therefore, even assuming [plaintiff] had suffered an adverse
    employment action, he did not produce evidence sufficient to
    overcome summary judgment on the question whether he suffered
    impermissible discrimination.”   
    Id.
    (ii)      Change in Status from Full-Time Regular
    to Part-Time Flexible
    In the Postal Service’s motion for summary judgment,
    defendant argues that plaintiff’s change in status from full-time
    regular to part-time flexible was neither an adverse action nor
    was it discriminatory/retaliatory.     (Def. Mem. At 10, 38-39, 42.)
    Plaintiff failed to respond to either of these arguments. His
    opposition to the motion for summary judgment contains no
    argument or any reference to record evidence regarding his change
    in status.   Given plaintiff’s utter disregard for his own claim,
    it is proper to treat defendant’s argument as conceded.     See
    Lytes v. D.C. Water and Sewer Auth., 
    572 F.3d 936
    , 943 (D.C. Cir.
    2009).13
    13
    Even if plaintiff had responded to defendant’s argument -
    which he did not - the Court finds it unlikely that plaintiff
    would be able to succeed on the merits of this claim.
    Specifically, defendant presented uncontroverted evidence that
    the USPS returned plaintiff to full time regular status
    retroactive to April 25, 1998, the first day his status was
    42
    (iii)     Denial of Request for Sick Leave
    In his Complaint, plaintiff alleges that “on several
    occasions in 1999 his request for sick leave was disapproved and
    changed to leave without pay.”   (Compl. ¶ 19.)   However, his
    argument in opposition to defendant’s motion for summary judgment
    is limited to a single date: he contends that the Postal Service
    discriminated against him based on his disability and retaliated
    against him when it denied his request for three hours of sick
    leave on September 9, 1999.   (Pl. Opp. at 7-8, 19-20.) This
    action, which resulted in plaintiff losing three hours of pay,
    may well constitute an adverse or materially adverse action.     See
    Franklin, 
    600 F. Supp. 2d at 72
     (being sent home without pay
    satisfies prima facie case for a materially adverse action)
    (citations omitted).
    The defendant has consistently explained that plaintiff was
    denied leave in error. (Def. Mem. at 23-34, 38; Def. Reply at
    11.)   Plaintiff’s sick leave request was mistakenly routed to the
    injury compensation office, which does not handle sick leave.
    Injury compensation specialist Toni Grier told the EEO office as
    changed, and credited him for any salary and leave adjustments.
    Accordingly, no adverse action occurred. (Def. Mem. at 11; Def.
    Facts at ¶ 32.) Defendant also presented uncontradicted evidence
    that as a result of the Snow Arbitration Award and Settlement,
    many employees’ job status changed at precisely the same time and
    in precisely the same way as plaintiff’s did. Defendant thus
    presented a legitimate, non-discriminatory reason for its action,
    which plaintiff has failed to rebut.
    43
    far back as 2000 that she does “not normally take action on
    [sick] leave requests . . . it was an oversight that I did in
    this instance.”   (Pl. Att. 1, p.14 (T. Grier Aff. Oct. 11,
    2000).)   In her deposition in 2008, nearly eight years after her
    initial affidavit, Grier offered the same explanation of mistake.
    She explained that she “should never signed the sick leave slip.
    Sick leave . . . should be approved by the supervisor, not by
    injury comp . . . leave for an injury has to be either leave
    without pay, IOD or COP.   Those are the only [] forms of leave
    that the injury compensation office handles.”   (Def. Deps., T.
    Grier Dep. at 43-44.)   While plaintiff claims Grier’s action “was
    not error or mis-communication but purposeful,” (Pl. Opp. at 7,)
    he offers no evidence to support this accusation, or to refute
    the Postal Service’s assertion of error.   On the contrary,
    plaintiff provides additional support for USPS’ claim of mistake
    by his assertion that Grier “mixed claim numbers and injuries.”
    (Pl’s Att. 1 p. 11, (Aff. A, Dated Jul. 6, 2000).)14   This
    evidence further supports defendant’s argument that Grier
    14
    As set forth more fully in Section I.B.2 above, plaintiff
    had filed a second workers compensation claim, which was assigned
    a different claim number and alleged different injuries than his
    original claim. The OWCP found no compensable injury and denied
    the second claim in July 1999; nevertheless, plaintiff continued
    to submit requests for leave without pay based on the invalid
    workers’ compensation claim after it had been denied. Indeed, in
    August 1999, plaintiff submitted three improper leave requests
    based on the already-denied workers’ compensation claim, none of
    which were granted. (Pl’s Ex. 1, Form 3971 dated 8/11/99,
    8/12/99, 8/13/99; Def. Mem. at 23-24, 38; Def. Reply at 11.)

    mistakenly construed his valid sick leave request as an improper
    request for leave without pay.
    As this Circuit has held, once the employer has articulated
    a non-discriminatory explanation for its action, as the Postal
    Service did here,
    the issue is not the correctness or desirability
    of [the] reasons offered, but whether the employer
    honestly believes in [the] reasons it offers . . .
    It is not enough for the plaintiff to show that a
    reason given for a job action is not just, or fair,
    or sensible. He must show that the explanation given
    is a phony reason.
    Fishbach v. D.C. Dep’t of Corr’s, 
    86 F.3d 1180
    , 1183 (D.C. Cir.
    1996) (internal quotations omitted); see also George v. Leavitt,
    
    407 F.3d 405
    , 415 (D.C. Cir. 2005) (“[A]n employer’s action may
    be justified by a reasonable belief in the validity of the reason
    given even though that reason may turn out to be false.”); Oates
    v. District of Columbia, 
    824 F.2d 87
    , 93 (D.C. Cir. 1987)(“[A]n
    ill-informed motivation, or even an illegal motivation, is not
    necessarily a discriminatory one.”).
    The Court concludes that plaintiff has failed to present the
    evidence necessary to rebut defendant’s explanation that Grier
    made an administrative error by denying plaintiff’s sick leave
    request.   Plaintiff himself acknowledged in his EEO affidavit
    that such a mistake may have occurred.   More important, he has
    not produced any evidence to show that the Agency’s actions were
    dishonest or otherwise a pretext for discrimination or
    45
    retaliation.       The Court therefore grants summary judgment for
    defendant on this claim.
    (iv)      Suspension
    During the summer of 1999, the Postal Service suspended
    plaintiff for approximately two or two and one-half days based on
    an incorrect determination that he was not eligible for limited
    duty.        As set forth more fully in section I.B.2 above, this error
    arose out of OWCP’s rejection of plaintiff’s second workers’
    compensation claim; specifically, when plaintiff’s operations
    manager received notice of the rejection, he believed,
    incorrectly, that plaintiff was no longer entitled to limited
    duty status.       This error was corrected later the same summer when
    plaintiff prevailed in a grievance his union filed on his behalf
    and the Postal Service paid him for 19.42 hours of pay he lost as
    a result of the suspension.15       (1998 ROI Ex. 16, 17, 18, pp. 61-
    63, and p. 133 (Info. for Precomplaint Counseling).)       Plaintiff
    argues that these circumstances amount to illegal disability
    discrimination and retaliation under the Rehabilitation Act.         The
    15
    Plaintiff claims, without support, that he received 19.41
    hours of pay when the grievance settled. (Pl. Facts at 4.)
    Plaintiff’s unsupported allegations are insufficient to withstand
    summary judgment. See, e.g., Fed. R. Civ. P. 56(e); Celotex, 
    477 U.S. at 322
     (non-moving party’s opposition must consist of more
    than mere unsupported allegations or denials). Even assuming
    that plaintiff only received 19.41 hours’ pay, plaintiff provides
    no evidence that his suspension lasted longer than 19.41 hours.
    Accordingly, the Court finds the one one-hundredth of an hour
    dispute between the parties irrelevant to plaintiff’s claim.
    46
    Postal Service responds that plaintiff did not suffer an adverse
    employment action or a materially adverse action.   The Court
    agrees with defendant.
    It is well settled in this Circuit that “absent some
    consequential harm or injury, a delay does not affect the terms,
    conditions or privileges of employment and does not constitute an
    adverse employment action.”   West v. Potter, 
    540 F. Supp. 2d 91
    ,
    95 (D.D.C. 2008)(citations omitted); see also Runkle v. Gonzales,
    
    391 F. Supp. 2d 210
    , 224-25 (D.D.C. 2005) (delay does not
    constitute materially adverse action for purposes of retaliation
    claim).   Plaintiff does not deny that when he prevailed in his
    grievance, he was paid for the entire length of his suspension.
    Because plaintiff does not show that he suffered any
    consequential harm from the delay in paying him for approximately
    two and one-half days of lost time, he fails to show he was
    subject to an adverse or materially adverse action.    Accordingly,
    the Court will grant defendant’s motion for summary judgment on
    plaintiff’s claim.
    (v)       May 3, 2000 Denial of Overtime
    Although the complaint alleges that plaintiff was unlawfully
    denied overtime throughout 1999 and 2000, (Compl. ¶¶ 24-26),
    plaintiff’s sole contention now is that he was discriminated
    against on the basis of race and disability when he was denied
    voluntary overtime on single occasion - May 3, 2000.   (Pl. Opp.
    47
    20-22.)   Defendant has proffered a legitimate, non-retaliatory
    reason for why plaintiff did not get overtime: he was ineligible
    for overtime on May 3, 2000 because he took two hours of annual
    leave during his regular shift that day.16   (2000 ROI, Ex. 1,
    p.17; Def. Mem. at 24, Def. Reply at 14; Def. Facts ¶¶ 40, 42.)
    Plaintiff does not dispute the factual basis for defendant’s
    denial of overtime: he did not work all of his regularly
    scheduled shift on May 3, 2000 because he elected to take annual
    leave.    Nor does he dispute that he is covered by the Collective
    Bargaining Agreement between the Postal Service and the American
    Postal Workers Union, which provides, in relevant part, “those
    16
    Defendant proffered two other non-discriminatory reasons
    for the overtime denial: (1) plaintiff was ineligible for
    overtime at the P&DC facility because he worked at the V Street
    Annex at the time, and overtime is only offered to employees who
    regularly work at the same location the overtime is offered; and
    (2) plaintiff’s physical limitations made him ineligible to
    perform the overtime offered at the P&DC that day. The Court
    finds defendant has not met its burden of production for either
    of these asserted reasons. With respect to the first reason,
    plaintiff argues that the return to sender unit moved to the P&DC
    the first week in May 2000, and plaintiff’s supervisor Deborah
    Boston admits in her affidavit that the unit may have moved to
    the P&DC by May 3. (2000 ROI p. 11, Boston Aff. Mar. 19, 2001.)
    With respect to the second reason, plaintiff asserts that the
    overtime work offered “was casing mail. The work that was
    performed by Plaintiff [sic] at his pay location was casing
    mail.” (Pl. Opp. at 21.) While the Postal Service claims
    plaintiff’s physical limitations precluded him from performing
    the overtime, the Agency has provided no evidence showing either
    the nature of the overtime work performed or how that work fit
    within plaintiff’s restrictions. Accordingly, defendant has
    failed to satisfy its burden of production to “offer admissible
    evidence sufficient for the trier of fact to conclude,” that
    plaintiff was denied overtime for these reasons. Reeves v.
    Sanderson Plumbing Prods., Inc., 
    530 U.S. 133
    , 142 (2000).
    48
    absent or on leave shall be passed over,” for overtime work.
    (2000 ROI Ex. 7b.)   His sole response to this argument is that
    the collective bargaining agreement permits individuals to work
    overtime on their non-scheduled days.   (Pl’s. Facts p. 2.)      This
    provision, however, is inapposite here.   Plaintiff does not claim
    the Postal Service denied him overtime on one of his non-
    scheduled workdays, which are Mondays and Tuesdays.   (2000 ROI
    Exs. 1, 3, and 4, pp. 17, 19, 20.)   Rather, he claims defendant
    refused to allow him overtime on a Wednesday, when the evidence
    shows that he took annual leave during part of his regularly
    scheduled shift.   The CBA prohibits the award of voluntary
    overtime under these circumstances.17   Accordingly, the Court
    finds that the Postal Service has met its burden and proffered a
    legitimate, non-retaliatory reason for its decision not to offer
    plaintiff voluntary overtime.   The Court further finds that
    plaintiff has “failed to introduce any evidence that would permit
    17
    This provision dovetails with the general policy goals of
    awarding voluntary overtime work. There is “clearly a tangible
    monetary advantage to those who are assigned overtime work.”
    Bell v. Gonzales, 
    398 F.Supp.2d 78
    , 97 (D.D.C. 2005). The Fair
    Labor Standards Act, which covers eligible USPS employees,
    requires employers to pay overtime compensation for employees
    working more than 40 hours per week “at a rate not less than one
    and one-half times the regular rate.” 
    29 U.S.C. § 207
    (a)(1). In
    other words, premium overtime pay is intended to compensate
    employees for working hours in addition to those regularly
    assigned. It is not intended to reward employees who take
    vacation time during their regularly scheduled working hours, and
    who then seek to avail themselves of significantly higher
    overtime rates by pursuing voluntary overtime opportunities.

    a trier of fact to believe that defendant’s proffered rationale
    for its decision . . . was pretextual or that its decision was
    motivated by a retaliatory animus.”   Franklin, 
    600 F. Supp. 2d at 71
     (citations omitted).
    (vi)     Lack of Opportunity for Discovery in
    Administrative Proceedings
    Plaintiff’s fifth EEO complaint alleges that the Agency
    breached the settlement agreement it entered into with plaintiff
    in 2003. (Def. Atts. 6-7.)   However, his complaint before this
    Court does not contain a breach of contract claim or a
    discrimination or retaliation claim relating to the breach of
    contract.   The sole allegation in the complaint which mentions
    the settlement reads, in relevant part:
    In January 2003, plaintiff filed a final [sic]
    complaint with the USPS EEO Office alleging
    retaliation based on the USPS’ decision to
    terminate plaintiff. The parties entered into
    a settlement agreement. When the USPS did not
    meet the terms of the settlement agreement,
    plaintiff filed an appeal with the EEOC Office
    of Federal Operations . . . Throughout the admini-
    strative process involving the complaints filed
    in 1998, 1999, 2000 and 2003, the Plaintiff was
    not allowed to engage in any discovery.
    (Compl. ¶ 10.)   The defendant correctly points out that “there is
    no cause of action” for federal employees to bring retaliation or
    discrimination claims based on “complaints of delay or
    interference in the investigative process.”   (Def. Mem. at 15
    (quoting Keeley, 
    391 F. Supp. 2d at 45
    ).) Rather, plaintiff’s
    50
    “sole remedy for complaints about the administrative
    investigative process is to bring a de novo action in federal
    court” against the party allegedly engaged in the underlying
    discrimination, and to seek discovery relating to his claims in
    court.    (Id. (quoting Keeley, 
    391 F. Supp. 2d at 45
    ).)   Plaintiff
    does not dispute defendant’s arguments, nor does his opposition
    brief contain any argument with respect to the settlement, its
    alleged breach, or his opportunity to take discovery in the
    administrative proceedings.   It is therefore proper to treat
    defendant’s argument as conceded, although, as just described, it
    succeeds on its merits in any event.     See Lytes, 
    572 F.3d at 943
    .
    (vii)     Pre-Disciplinary Interview on January
    18, 2006
    In its motion for summary judgment, defendant argues that
    plaintiff’s pre-disciplinary interview was neither an adverse
    action nor was it discriminatory/retaliatory.    (Def. Mem. at 16,
    25-29, 41-44.)   The Court agrees.    See, e.g., Franklin, 
    600 F. Supp. 2d at 68-69
     (holding plaintiff’s pre-disciplinary interview
    for poor attendance not an adverse action) (citing McDaniel v.
    Potter, Nos. 06-CV-0803 & 06-CV-1371, 
    2007 WL 3165807
    , *6, *8-9
    (N.D. Ohio Oct. 26, 2007) (same)).
    As set forth above, the Court finds that defendant’s
    argument regarding the pre-disciplinary interview succeeds on its
    merits.   In addition, plaintiff failed to respond to defendant’s
    arguments.   His opposition to the motion for summary judgment
    51
    contains no argument or record evidence that the pre-disciplinary
    interview constitutes adverse action.    Accordingly, the Court may
    also treat claim seven as conceded.     See Lytes, 
    572 F.3d at 943
    .
    (viii)    Removal from Postal Service
    The Court now turns to plaintiff’s most significant claim:
    his removal from the Postal Service in 2006.    At the outset, the
    Court notes that the Agency’s actions toward the plaintiff during
    the four years from when he was initially sent home, in 2002, to
    his ultimate removal in 2006, were far from unassailable.
    Indeed, the Postal Service took positions during that time which,
    in this Court’s view, were both confusing and contradictory.
    However, the relevant inquiry is not whether the Postal Service
    treated plaintiff justly, fairly, or sensibly.    It is whether the
    Agency asserted a legitimate, non-discriminatory reason for the
    termination, and if so, whether plaintiff has shown that the
    employer’s reason was not the actual reason, but was pretext for
    discrimination or retaliation.   See Brady, 
    520 F.3d at 494
    ;
    Baloch, 
    550 F.3d at
    1197 n.2; Kersey, 
    586 F.3d at
    17 n.1-2.    For
    the reasons that follow, the Court concludes that plaintiff has
    not met his burden.
    Defendant argues that “plaintiff’s employment was terminated
    because he failed to report to work as directed, and he failed to
    provide updated medical documentation showing either an inability
    to work or an ability to work with certain restrictions.”    (Def.
    52
    Mem. at 35.)   These two reasons are factually inseparable.
    Defendant sent plaintiff home in the first instance because it
    could not provide him with work assignments consistent with his
    medical restrictions.   (2006 ROI, Aff. A. p. 33 of 39(Jan. 23,
    2002 letter from J. Szarek to plaintiff); p. 35 of 39 (Sept. 27,
    2004 letter from H. Jackson-Baker to plaintiff).)   Accordingly,
    in the view of Agency management, plaintiff had the
    responsibility to provide the Postal Service with updated
    documentation of his restrictions, so the Agency could make an
    informed decision about whether, and in what capacity, he could
    return to duty.18   (Def. Facts ¶¶ 47-57; Def. Reply at 15-16; Def.
    Deps., Bears-Mitchell Dep. 50, 114-116.)
    As Defendant correctly notes in its motion for summary
    judgment, “the record is replete with examples of plaintiff’s
    failure to provide requested documentation, and in those
    instances when he did provide such information, he did not
    provide it to the appropriate person.”   (Def. Mem. at 35.)
    Specifically, the USPS clearly requested or demanded plaintiff to
    provide updated medical documentation on at least eight separate
    occasions:
    18
    This position is generally consistent with federal law
    and policy. As explained supra at footnote 2, the Federal
    Employees Compensation Act requires that federal employees
    injured on the job be compensated for their injuries, and the
    Secretary of Labor requires that the Postal Service make special
    efforts to employ those injured employees, who will otherwise be
    eligible for compensation for doing nothing.

    (id., Ex. 10.); and
    •    January 18, 2006 pre-disciplinary interview with Bears-
    Mitchell, plaintiff, and plaintiff’s shop steward. (id., Ex.
    13.)
    The record is undisputed that plaintiff failed to comply
    with six of these requests altogether, and that his response to
    the other two fell far short of the Postal Service’s requests.
    As set forth in more detail in Sections I.A and I.B.4 above,
    although he provided one CA-17 form in response to the March 2003
    settlement agreement, he produced it two months after it was due,
    and to the wrong office at the Agency.   And while he provided one
    additional CA-17 form, dated November 21, 2005, to the Agency,
    54
    this belated and minimal documentation was an obviously deficient
    response to the Agency’s multiple requests that he provide
    immediate evidence, updated every 30 days, regarding his medical
    restrictions.
    Plaintiff provides no evidence that he responded to the
    Postal Service’s repeated requests for medical documentation
    beyond these two isolated instances.   Rather, he argues that the
    requests themselves were absurd because he was sent home by the
    Postal Service in 2002 and was never recalled to duty.   (Pl. Opp.
    9-10.)   Plaintiff’s anger is clear.   In response to defendant’s
    January 2003 letter demanding documentation of his medical
    restrictions, plaintiff declines to provide documentation as
    requested, then states that the documents he “will provide along
    with this cover letter, will no doubt explain” his
    “unsubstantiated absence.”   He continues, “[t]hese documents will
    also demonstrate beyond a reasonable doubt, the stupidity,
    Incompetance, [sic] and illogical reasons for [the] request”
    because on January 23, 2002 he received a letter from the Postal
    Service telling him not to report for duty.   (Pl. Att. 3, p. 5
    (Jan. 29, 2003 Letter from Plaintiff to USPS).)
    While plaintiff’s subsequent reactions to the defendant’s
    request for documentation are marked by less colorful language,
    his disdain for the Postal Service’s position remains evident.
    After receiving defendant’s third request for documentation in
    55
    September 2004, plaintiff responded, not by providing the
    requested information, but by stating “my absence from the Postal
    Service is not directly related to Illness or Injury, my absence
    is directly related to Toni Grier, Compensation Unit.     Ms. Grier
    has not abided by the [settlement] agreement . . . I’m quite sure
    these documents will answer your questions.”    (2006 ROI, Aff. A.
    P. 31 of 39 (Oct. 7, 2004 letter from Plaintiff to Jackson).)      By
    “these documents,” plaintiff refers to the January 2002 letter
    sending him home and the March 7, 2003 Settlement Agreement,
    which itself required plaintiff to update his medical
    restrictions and with which plaintiff did not comply.    Plaintiff
    did not provide any documentation updating his medical
    restrictions with his October 2004 submission to the Postal
    Service.
    Plaintiff continued to refuse to provide updated medical
    documentation throughout the balance of 2004 and nearly all of
    2005.    He attended pre-disciplinary meetings, produced other
    documents, and even filed a grievance with his union, but did not
    provide a single piece of evidence relating to his work
    restrictions until December 2005.
    Finally, on February 1, 2006, Bears-Mitchell drafted a
    recommendation for removing plaintiff from the Postal Service.
    The recommendation states that plaintiff was “AWOL from May 20,
    2003 to June 24, 2005.    He has not provided us with acceptable
    56
    medical documentation.   He was given a pre-disciplinary interview
    on January 18, 2006, [at] which I informed him of his
    unacceptable medical documentation.    To date I have had no
    response.”   (2006 ROI, Aff. C p. 9 of 9.)   Plaintiff was
    terminated effective March 31, 2006.
    The Court is not unsympathetic to plaintiff’s position.       It
    is seemingly illogical that the Postal Service, which sent
    Plaintiff home in the first instance, would demand continuing
    justification from Plaintiff to remain involuntarily out of work,
    and would judge him “absent without leave” without ever summoning
    him to return to duty.   However, plaintiff’s claims do not rise
    and fall on the logic of the employer’s action.    “The question is
    never whether the employer was mistaken, cruel, unethical, out of
    his head, or downright irrational in taking the action for the
    stated reason, but simply whether the stated reason was his
    reason: not a good reason, but the true reason.”     Forrester v.
    Rauland-Borg Corp., 
    453 F.3d 416
    , 418 (7th Cir. 2006).       The
    record evidence in this case demonstrates that over a period of
    three years, the Postal Service repeatedly, consistently and
    clearly told plaintiff to provide updated medical documentation
    and warned him that failure to do so could result in discipline
    up to and including termination.     Plaintiff failed to comply with
    these requests.   Accordingly, the Court finds that the Postal
    Service has carried its burden by demonstrating that it
    57
    terminated plaintiff for a legitimate, non-discriminatory reason:
    failing to provide updated medical documentation.
    Plaintiff makes several arguments that the Agency’s reason
    for terminating him was pretextual.   He argues that (1) the
    notice of removal listed other reasons for his termination, which
    are illegitimate; (2) the Postal Service advanced yet another
    illegitimate reason for termination - plaintiff’s refusal to
    accept a job offer from the Agency; and (3) plaintiff was treated
    less favorably than a similarly-situated woman.   After careful
    consideration, and for the reasons set forth below, the Court
    finds that none of plaintiff’s arguments discredits defendant’s
    asserted non-discriminatory reason for his termination.
    In his Opposition, plaintiff states: “the Postal Service put
    forth two reasons for terminating [him]: 1) being AWOL from May
    20, 2003 to June 24, 2005; 2) failure to provide a document to
    support his statement that he was sent home on January 25, 2002.
    The Plaintiff can rebut both these reasons.”   (Pl. Opp. at 13,
    (citing Notice of Removal).)   The Court agrees that plaintiff has
    rebutted the second reason; however, he has failed to rebut the
    first.
    Plaintiff clearly demonstrates that he repeatedly documented
    the Postal Service’s decision to send him home, and that the
    Agency knew it.   He correctly points out that in both 2003 and
    2004 he provided the Agency with copies of its own letter of
    58
    January 23, 2002, which states, in relevant part, “due to the
    closure of the Brentwood facility . . . Plant Operations has
    indicated it is no longer able to accommodate your restrictions.
    Effective Friday, January 25, you should no longer report” for
    work.    (Pl. Att. 3, Jan 23, 2002 Letter.)   Moreover, he correctly
    notes that in 2004 the Postal Service acknowledged, in writing,
    that it had sent him home in 2002. (Pl. Opp. at 13-14, (citing
    Sept. 27, 2004 Letter from H. Jackson-Baker to Plaintiff).)
    Defendant provided no evidence to counter plaintiff’s clear
    and convincing evidence that the Postal Service instructed him to
    go home in 2002, and that he repeatedly documented that fact to
    the Postal Service.    Indeed, defendant did not even mention this
    “reason” for his termination in its motion for summary judgment.
    The Court thus has no trouble concluding that any alleged doubts
    defendant had about the circumstances of plaintiff being sent
    home in 2002 were not a true reason for his termination.
    However, the Court cannot find that the plaintiff has
    rebutted the other reason for removal stated in his Notice of
    Termination: the fact that he was AWOL.    In his opposition,
    plaintiff argues that he did not go to work because he “was told
    not to report to work, effective January 25, 2002.    He never
    received a call nor letter to return to work,” accordingly, he
    could not have been AWOL. (Pl. Opp. at 14.)    This argument misses
    the mark.    As set forth above, the issues of plaintiff’s failure
    to report to work and his failure to provide medical
    59
    documentation are in fact one and the same.   Defendant sent
    plaintiff home in 2002 because it could not provide him with work
    consistent with his medical restrictions.   The Postal Service
    took the position that from that point on, it was plaintiff’s
    burden to regularly update his medical documentation.    Without
    such continuing documentation, Agency managers claimed, they had
    no way to know whether plaintiff had any restrictions and no way
    to assess whether and in what capacity plaintiff could return to
    work.   And the Agency further took the position – clearly,
    repeatedly, and often in ALL CAPITAL LETTERS, that without
    medical evidence demonstrating that plaintiff did have
    restrictions, the Agency would assume that he had none, and
    accordingly, was AWOL.   The record demonstrates that Postal
    Service management clearly and consistently communicated its
    position to plaintiff, who chose to provide little to no
    information responsive to its requests.   Plaintiff offers no
    evidence that the USPS selectively enforced the medical
    documentation requirements against males, African-Americans,
    employees with disabilities or plaintiff in particular.    Rather,
    as already described, plaintiff takes the position that the
    Agency’s demands for continuous medical updates were foolish and
    unnecessary.   The Court does not necessarily disagree with the
    substance of that position.   However, this Court does not sit as
    a “super-personnel department that [re]examines an entity’s
    60
    business decisions”, even in termination cases.    Kelly v. Mills,
    –- F.Supp.2d –-, 
    2010 WL 22669
    , *18 (D.D.C. Jan. 6,
    2010)(internal quotations omitted).   Accordingly, the Court finds
    that “plaintiff’s disagreement with USPS policy on [the need to
    submit updated] medical documentation would not cause a
    reasonable jury to find that defendant’s stated reason for
    plaintiff’s” termination – failure to submit the required
    documents - “is a pretext for . . . discrimination.”    Franklin,
    
    600 F. Supp. 2d at 73
     (quoting Lawson v. Potter, 
    463 F.Supp.2d 1270
    , 1286 (D. Kan. 2006)).
    Plaintiff next argues that his termination is unlawful
    because he can rebut yet another reason proffered by the Postal
    Service for termination: its claim that the Agency offered him a
    job in 2003 and/or 2005, which he turned down.    (Pl. Opp. at 15-
    16.)   Assuming arguendo that plaintiff has rebutted this reason,
    the Court’s analysis does not change; as discussed above, the
    Court has already found that defendant has proffered one
    legitimate, non-retaliatory reason for terminating plaintiff, and
    plaintiff has failed to show that reason is pretext for
    discrimination or retaliation.   As plaintiff concedes in his
    opposition brief, the employer only needs one good reason to
    succeed on summary judgment.   (Pl. Opp. at 6, citing Aka v.
    Washington Hosp. Ctr., 
    156 F.3d. 1284
    , 1292 (D.C. Cir. 1998) (“if
    the only explanations set forth in the record have been rebutted,
    61
    the jury is permitted to search for others, and may, in
    appropriate circumstances draw an inference of discrimination.”))
    See also Furnco Const. Corp. v. Waters, 
    438 U.S. 567
    , 577 (1978)
    (It is only when “all legitimate reasons for [an adverse action]
    have been eliminated as possible reasons for the employer’s
    actions” that the fact finder can infer that “the employer, who
    [the fact finder] generally assume[s] acts only with some reason,
    based [its] decision on an impermissible consideration.”)
    (emphasis in original).
    Finally, plaintiff’s evidence regarding a purportedly
    similarly situated female co-worker is insufficient to show that
    defendant’s termination of plaintiff was merely a pretext for
    gender based determination.   To show that employees are similarly
    situated, “plaintiff . . . must demonstrate that all of the
    relevant aspects of [his] employment situation were ‘nearly
    identical’ to those of [his comparables].”   Bolden v. Winter, 
    602 F. Supp. 2d 130
    , 140 (D.D.C. 2009) (citations omitted).
    Plaintiff has failed to meet his burden.   In his opposition,
    plaintiff states that Ms. Thomas was injured on the job, laid off
    in January 2002, and called back to work at the P&DC in 2004.
    (Pl. Opp. at 18.)   He then declares, without any evidentiary
    support or citation to the record, that “Ms. Thomas was never
    judged AWOL and she was never subjected to any pre-disciplinary
    hearings or asked for additional medical information or subject
    62
    to removal.”   (Id.)
    To defeat a motion for summary judgment, the non-moving
    party’s opposition must consist of more than mere unsupported
    allegations or denials and must be supported by affidavits or
    other competent evidence setting forth specific facts showing
    that there is a genuine issue for trial.   Fed. R. Civ. P. 56(e);
    Celotex Corp., 477 U.S. at 322.    Plaintiff’s allegations are
    wholly without support, and are thus insufficient to establish a
    genuine issue of material fact and defeat defendant’s motion for
    summary judgment.
    B.   Hostile Work Environment
    Plaintiff argues that he “has made out a claim for hostile
    work environment based on race and retaliation.”   (Pl. Opp. at
    22.)   He does not specify what alleged conduct he bases his claim
    upon, but states generally that “the conduct of which the
    plaintiff complains were [sic] not so isolated or discrete but
    consisted of several actions which were ongoing at the same
    time.” (Opp. at 23.)   In the absence of any other indication from
    the plaintiff, the Court infers from this statement that
    plaintiff bases his hostile work environment claim on the same
    acts upon which he bases his discrimination/retaliation claims.
    Plaintiff cannot rely on the discrete acts upon which he
    bases his claims of discrimination and retaliation claims to
    establish he was subject to a hostile work environment.    To
    63
    prevail on a hostile work environment claim, “a plaintiff must
    show that his employer subjected him to discriminatory
    intimidation, ridicule, and insult that is sufficiently severe or
    pervasive to alter the conditions of the victim’s employment and
    create an abusive working environment.”   Baloch, 
    550 F.3d at 1201
    (citations omitted.)   Another judge on this Court has
    persuasively explained the distinction between disparate
    treatment and hostile work environment claims, in addition to the
    perils of permitting plaintiff to conflate the two:
    The dangers of allowing standard disparate treatment
    claims to be converted into a contemporaneous hostile
    work environment claim are apparent. Such an action
    would significantly blur the distinctions between both
    the elements that underpin each cause of action and
    the kinds of harm each cause of action was designed to
    address. A hostile work environment [claim]. . . must
    be based on one unlawful employment practice of
    pervasive, insulting, discriminatory conduct that makes
    the plaintiff's day-to-day work environment severely
    abusive. Therefore, cobbling together a number of
    distinct, disparate acts will not create a hostile work
    environment. For example, if an employee is discrimin-
    atorily denied ten promotions over a period of time, that
    pattern of conduct may give rise to ten separate claims
    under Title VII, but it would not create a hostile work
    environment claim based on pervasive intimidation,
    insult and ridicule.
    Rattigan v. Gonzales, 
    503 F. Supp. 2d 56
    , 82 (D.D.C. 2007)
    (alterations, citations, and internal quotation marks omitted)
    (Huvelle, J.).
    The Rattigan court’s reasoning applies with equal force in
    this case, and clearly demonstrates why plaintiff's attempt to
    raise a hostile work environment claim is unavailing.    Plaintiff
    64
    has done nothing more than reassert his disparate treatment and
    retaliation claims - all of which are discrete employment actions
    – and baldly claim that these same actions constitute a hostile
    work environment.   The conclusory invocation of the term “hostile
    work environment” is insufficient to transform the nature of his
    claims. See Rattigan, 503 F. Supp. 2d at 81 (“Plaintiff should
    not be permitted to ‘bootstrap’ his alleged discrete acts of
    discrimination and retaliation into a broader hostile work
    environment claim.” (quoting Keeley, 
    391 F. Supp. 2d at 51
    ;
    Lester v. Natsios, 
    290 F. Supp. 2d 11
    , 31-33 (D.D.C. 2003)
    (rejecting the plaintiff's argument that “the specific alleged
    incidents of discrimination she has raised collectively
    constitutes a hostile work environment”; noting that “it is not
    at all clear that mere reference to alleged disparate acts of
    discrimination against plaintiff can ever be transformed, without
    more, into a hostile work environment claim.”)).
    Even assuming arguendo that plaintiff could “simply
    regurgitate his disparate treatment claims in an effort to flesh
    out a hostile work environment claim,” his effort fails given the
    facts of this case.   Smith v. Jackson, 
    539 F. Supp. 2d 116
    , 138
    (D.D.C. 2008).   Plaintiff’s claims in this case constitute eight
    discrete instances of alleged discrimination/retaliation over a
    period of eight years.   Some of the acts alleged are as
    temporally minute as missing three hours’ sick leave or losing an
    overtime opportunity on a single day.   The alleged conduct simply
    65
    does not translate into “pervasive, insulting, discriminatory
    conduct that makes the plaintiff's day-to-day work environment
    severely abusive,” which is the standard he must meet to sustain
    a hostile work environment claim.     Rattigan, 503 F. Supp. 2d at
    82 (citing Nat’l R.R. Passenger Corp. v. Morgan, 
    536 U.S. 101
    ,
    117 (2002); Oncale v. Sundowner Offshore Services, Inc., 
    523 U.S. 75
    , 81 (1998).)    Accordingly, the Court grants summary judgment
    on plaintiff’s hostile work environment claim.
    IV.   CONCLUSION
