    v.                                              (D.C. No. 98-WM-1651)

    UNITED AIRLINES, a corporation,
    Defendant-Appellee.
    ORDER AND JUDGMENT           *
    Before TACHA , EBEL , and BRISCOE , Circuit Judges.
    After examining the briefs and appellate record, this panel has determined
    unanimously that oral argument would not materially assist the determination of
    this appeal.   See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is
    therefore ordered submitted without oral argument.
    Plaintiff-appellant Mina Lundien appeals from the district court’s order
    granting summary judgment in favor of defendant United Airlines (United) in her
    *
    This order and judgment is not binding precedent, except under the
    doctrines of law of the case, res judicata, and collateral estoppel. The court
    generally disfavors the citation of orders and judgments; nevertheless, an order
    and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.
    action claiming that United demoted her on the basis of gender in violation of
    Title VII and in retaliation for her complaint of disparate treatment. We affirm
    the district court’s grant of summary judgment on plaintiff’s retaliation claim.
    Because the record indicates that plaintiff made a prima facie showing of gender
    discrimination under Title VII and offered sufficient evidence of pretext to create
    a genuine dispute of material fact as to the validity of United’s articulated reason
    for demoting her, however, we reverse the grant of summary judgment on her
    Title VII discrimination claim.
    I. Background
    The evidence and all reasonable inferences derived therefrom are presented
    here in a light most favorable to the plaintiff, as the nonmoving party.   See
    Bullington v. United Air Lines   , Inc ., 
    186 F.3d 1301
    , 1313 (10th Cir. 1999).
    Plaintiff was hired by United in 1991 as a part-time ramp serviceworker. One
    year later, she was promoted to ramp team leader at United’s Denver terminal, a
    management position. Her responsibilities included supervising the loading and
    unloading of baggage onto airplanes. Only three of United’s thirty-six ramp team
    leaders in Denver were women. Plaintiff informally complained to supervisors on
    at least two occasions that she believed she was being treated less favorably
    because she was a woman; however, she never filed formal complaints with
    United alleging discrimination.
    -2-
    Plaintiff was demoted from her job and precluded from all management
    positions with United after an August 13, 1997 incident. Plaintiff was called to
    investigate two packages that had been loaded on a flight from Houston to
    Colorado Springs, and were now stopped-over in Denver. One package, a bucket,
    had opened during the flight, spilling its contents of shotgun shells. The
    passenger who had checked the bucket had also checked a forty-two pound box.
    The box had two warning labels on it, one stating it contained flammable
    explosives, the other stating it contained black powder, but this second label was
    crossed out with black marker. Plaintiff asked one of her employees, William
    Peterson, to find out what the rules were concerning the handling of these two
    packages. She also asked that the passenger be brought to the boarding gate in
    the terminal so that she could speak with him about the packages.
    The passenger was waiting inside the gate when plaintiff arrived to
    interview him. He confirmed the packages were his, and explained that he was a
    member of the United States Olympic shooting team. The passenger told plaintiff
    that the box was mislabeled and contained more shotgun shells, not flammable
    explosives or black powder. United usually allowed passengers to check only
    eleven pounds of ammunition. In December 1995, however, United had granted a
    variance to the U.S. Olympic shooting team, effective until January 1998,
    allowing team members to check up to two fifty-pound boxes of shotgun shells.
    -3-
    This variance was on file with United at the time, applied to this passenger, and
    was noted on his passenger name record (PNR) in United’s computer.      See
    Appellant’s App., Vol. II, 226-28, 235. Plaintiff told the passenger the open
    bucket had to be removed from the flight because it was improperly packaged.
    Based on the passenger’s statements, however, plaintiff determined that the
    second package could remain on board.
    In the meantime, Peterson had called United’s training department, which
    advised him to hold both packages off the flight for further inspection. It appears
    from the record that neither Peterson nor the training department were aware at
    that time that the passenger was a member of the Olympic shooting team with a
    variance allowing him to check up to 100 pounds of ammunition. When plaintiff
    returned and told Peterson the box could remain on the flight, he protested.
    Believing that the package violated United’s usual eleven-pound limit, Peterson
    instructed the gate crew not to load either package. However, when plaintiff
    returned to the gate, she removed the flammable explosive label from the box
    based on the passenger’s representations, and ordered the crew to load it. When
    Peterson heard about this, he called the pilot and told him that the package
    exceeded United’s weight limit for ammunition.    
    Id. Vol. I
    at 148. The pilot
    instructed Peterson to remove the package. Peterson filed a report the next day
    with United claiming that plaintiff had violated United’s eleven-pound weight
    -4-
    limit. United concedes that the box was, in fact, properly packaged and did not
    contain any hazardous materials.   
    Id. Vol. I
    I, at 289.
    United’s Ramp Manager, Deborah Garner, investigated this incident.
    Plaintiff testified that during the investigation she repeatedly asked what rule or
    policy she was alleged to have violated, but United did not cite any. Plaintiff
    testified that all of Garner’s questions focused on the eleven-pound weight
    limitation for ammunition. A ramp team leader who was involved in the
    investigation, Rich Feller, testified that the only reason he heard given to plaintiff
    as to why her actions were wrong was the claimed violation of United’s eleven-
    pound weight limitation. However, Garner was informed about United’s variance
    for Olympic team members during the investigation.        
    Id. at 230.
    At the conclusion of the investigation, Garner recommended to Rodney
    Gonzales, a manager in United’s “People Services” department, that plaintiff be
    removed from all safety-related management positions. Plaintiff then spoke with
    Gonzales and said she hoped “that this [was] not an example of disparate
    treatment.” 
    Id. at 269.
    Gonzales determined that plaintiff should be removed
    from all management positions with United. In Garner’s letter demoting plaintiff
    she stated only that plaintiff had exercised “poor judgment” and that her actions
    were “inappropriate.”   
    Id. at 222.
    The letter did not explain how plaintiff had
    exercised poor judgment, nor did it claim that plaintiff had violated any of
    -5-
    United’s rules or policies. Plaintiff was placed on thirty-days’ paid administrative
    leave and told that she would be terminated if she was unable to secure a
    nonmanagement position with United within ninety days. Plaintiff applied for
    two jobs with United during this period, but was not hired for either and,
    therefore, was terminated from employment in December 1997.
    Plaintiff filed a discrimination claim with the Equal Employment
    Opportunity Commission, which issued plaintiff a right-to-sue letter. Plaintiff
    then filed a timely complaint in federal court alleging that United demoted and
    terminated her based on gender discrimination and in retaliation for her
    complaints of disparate treatment. Plaintiff’s complaint also asserts pendent state
    law claims for discrimination, breach of contract, and promissory estoppel, but
    plaintiff has not raised these claims on appeal; thus, they are deemed waived.    See
    Headrick v. Rockwell Int’l Corp.    , 
    24 F.3d 1272
    , 1277-1278 (10th Cir. 1994).
    The district court granted United’s motion for summary judgment, ruling that
    plaintiff had failed to present evidence that her demotion was motivated, at least
    in part, by her gender. Appellant’s App., Vol. IV at 684.
    -6-
    II. Analysis
    A. Standard of Review
    “We review the district court’s grant of summary judgment de novo,
    applying the same legal standard as the court below.”       Munoz v. St. Mary-Corwin
    Hosp ., 
    221 F.3d 1160
    , 1164 (10th Cir. 2000). Summary judgment is appropriate
    “if the pleadings, depositions, answers to interrogatories, and admissions on file,
    together with the affidavits, if any, show that there is no genuine issue as to any
    material fact and that the moving party is entitled to a judgment as a matter of
    law.” Fed. R. Civ. P. 56(c). “In applying this standard, we examine the factual
    record and draw reasonable inferences therefrom in a light most favorable to the
    nonmoving party.”      Munoz , 221 F.3d at 1164.
    B. McDonnell Douglas
    Plaintiff relies on indirect evidence to support her claim of unlawful
    discrimination. Thus, we analyze her claim using the three-step, burden-shifting
    framework first articulated in    McDonnell Douglas Corp. v. Green     , 
    411 U.S. 792
    (1973). Kendrick v. Penske Transp. Servs., Inc.       , 
    220 F.3d 1220
    , 1226 (10th Cir.
    2000) .
    Under the McDonnell Douglas framework, the plaintiff must carry
    the initial burden under the statute of establishing a prima facie case
    of racial discrimination. Once the plaintiff has established a prima
    facie case, the burden then must shift to the employer to articulate
    some legitimate, nondiscriminatory reason for its employment action.
    -7-
    If the defendant makes this showing, the plaintiff must then show
    that the defendant’s justification is pretextual.
    
    Id. (quotations omitted).
    1. Prima Facie Case and
    Legitimate, Nondiscriminatory Explanation
    To establish a prima facie case of discriminatory discipline or demotion, a
    plaintiff must show that she was (1) a member of a protected group, (2) qualified
    for the job, (3) despite her qualifications, she was demoted from the position, and
    (4) the job was not eliminated after her demotion.    See Perry v. Woodward ,
    
    199 F.3d 1126
    , 1135 (10th Cir. 1999),     cert. denied , 
    120 S. Ct. 1964
    (2000).
    United does not dispute that plaintiff established a prima facie case of
    discrimination.
    The burden then shifted to United to articulate a legitimate,
    nondiscriminatory reason for demoting plaintiff. United’s proffered justification
    is that plaintiff “made a series of highly questionable decisions with potentially
    very serious safety ramifications, causing Ms. Garner to lose confidence in her
    ability to lead her workforce.” Appellant’s App. Vol. I, at 99. Plaintiff does not
    dispute on appeal the district court’s conclusion that United’s explanation
    satisfies its second-stage burden.   See EEOC v. Flasher Co. , 
    986 F.2d 1312
    , 1316
    (10th Cir. 1992) (defendant need only articulate through some proof a facially
    -8-
    nondiscriminatory reason; it need not litigate the merits of the reasoning at this
    stage of the proceeding).
    2. Evidence of Pretext
    If a plaintiff “presents evidence that the defendant’s proffered reason for
    the employment decision was pretextual-i.e. unworthy of belief, the plaintiff can
    withstand a summary judgment motion and is entitled to go to trial.”        Randle v.
    City of Aurora , 
    69 F.3d 441
    , 451 (10th Cir.1995);      see also Reeves v. Sanderson
    Plumbing Prods., Inc ., 
    120 S. Ct. 2097
    , 2109 (2000) (holding that “a prima facie
    case and sufficient evidence to reject the employer’s explanation may permit a
    finding of liability”). Plaintiff contends, correctly, that the district court applied
    an incorrect legal standard at the third stage of the    McDonnell Douglas analysis
    in evaluating her evidence of pretext. Citing an Eleventh Circuit articulation of
    the standard, the district court ruled that even if plaintiff had presented evidence
    that her actions on August 13, 1997, complied with United’s rules and
    regulations, and that her demotion was based on erroneous facts, she failed to
    establish pretext because she did not present “evidence indicating that her
    demotion was motivated, at least in part, by her gender.” Appellant’s App.
    Vol. IV, at 684. This is a “pretext-plus” test, which the Supreme Court recently
    rejected in Reeves , 120 S. Ct. at 2109, and which this court previously rejected in
    
    Randle, 69 F.3d at 451-53
    & 452 n.16 (citing        St. Mary’s Honor Ctr. v. Hicks , 509
    -9-
    U.S. 502, 507 (1993)). Because a showing of pretext, in itself, is all that is
    required to raise the inference of discriminatory intent, and no additional showing
    of actual discriminatory animus is necessary, the district court incorrectly
    evaluated plaintiff’s evidence.
    Plaintiff further contends she presented sufficient evidence of pretext to
    withstand summary judgment. We agree. She presented evidence that United’s
    proffered justification for demoting her is suspect because it gave only a vague
    and subjective explanation for its action, and never specified what plaintiff did
    wrong. She also showed that after she filed her complaint, United gave
    explanations that were not the subject of the disciplinary investigation and were
    not consistent with its standard policies and procedures. After reviewing the
    admissible evidence plaintiff presented in response to United’s motion for
    summary judgment, we conclude that plaintiff has shown that a jury could reject
    United’s proffered explanation.   Hicks , 509 U.S. at 511.   1
    1
    United contends that much of the evidence presented by plaintiff is
    insufficient to withstand summary judgment because it is inadmissible hearsay;
    generalized, unsupported opinions; speculation and conjecture; or states legal
    conclusions. Some of plaintiff’s evidence, particularly her evidence that female
    ramp team leaders were treated less favorably than their male counterparts, is
    hearsay or general opinions unsupported by facts. In assessing plaintiff’s
    evidence, we have considered only that evidence which we have concluded to be
    admissible in a summary judgment proceeding.     See Gross v. Burggraf Constr.
    Co. , 
    53 F.3d 1531
    , 1541 (10th Cir. 1995) (describing admissible evidence under
    Rule 56).
    -10-
    A plaintiff can show pretext by revealing “such weaknesses,
    implausibilities, inconsistencies, incoherencies, or contradictions in the
    employer’s proffered legitimate reasons for its action that a reasonable factfinder
    could rationally find them unworthy of credence.”     Morgan v. Hilti, Inc. , 
    108 F.3d 1319
    , 1323 (10th Cir. 1997) (quotations omitted).
    [T]he evidence which a plaintiff can present in an attempt to
    establish that a defendant’s stated reasons are pretextual may take a
    variety of forms. . . . A plaintiff may not be forced to pursue any
    particular means of demonstrating that a defendant’s stated reasons
    are pretextual. A plaintiff typically makes a showing of pretext in
    one of three ways: (1) with evidence that the defendant’s stated
    reason for the adverse employment action was false; (2) with
    evidence that the defendant acted contrary to a written company
    policy prescribing the action to be taken by the defendant under the
    circumstances; or (3) with evidence that the defendant acted contrary
    to an unwritten policy or contrary to company practice when making
    the adverse employment decision affecting the plaintiff.
    Kendrick , 220 F.3d at 1230 (citations, quotation and alterations omitted).
    Plaintiff’s evidence indicates that the explanation proffered by United for
    the discipline is subjective and vague. The only explanation given by United at
    the time of the discipline was its statement that plaintiff exercised poor judgment
    and acted inappropriately, and that Garner had lost confidence in her. There is
    nothing in the record to indicate that United told plaintiff how it is that she
    exercised poor judgment or acted inappropriately or why Garner lost confidence
    in her. Rich Feller, the ramp team leader who participated in the investigation,
    testified that plaintiff was told the basis of the demotion was that the ammunition
    -11-
    weighed too much; that there was a “safety issue” with the shipment; and that
    plaintiff had “broken the trust.” Appellant’s App., Vol III at 396-98. Months
    later, when plaintiff applied for unemployment benefits after her termination, the
    Colorado Department of Labor and Employment was unable to obtain from United
    any explanation as to why plaintiff was discharged, and made a finding in
    February 1998 that plaintiff was discharged “without being given a reason.”        
    Id. Vol. I
    I at 224.
    The use of subjectivity in the decision-making process can create a “strong”
    inference of bias if the plaintiff shows a significant disparity in the representation
    of a particular group.   Bauer v. Bailar , 
    647 F.2d 1037
    , 1045 (10th Cir. 1981).
    Here, only three of United’s thirty-six ramp team leaders in Denver were women,
    clearly a significant disparity in representation. United does not contend that
    plaintiff actually violated any of its rules. Appellee’s Br. at 32. Without its
    subjective explanations that Garner “lost confidence” in plaintiff because she
    exercised “poor judgment,” United cannot account for why it demoted and
    ultimately terminated plaintiff.
    Plaintiff presented evidence indicating that United gave shifting
    explanations for what plaintiff did wrong.      See Cole v. Ruidoso Mun. Sch. , 
    43 F.3d 1373
    , 1380-81 (10th Cir. 1994). Plaintiff testified that during the
    investigation, all Garner implied that she had done wrong was allow a passenger
    -12-
    to board more than eleven pounds of ammunition. Appellant’s App. Vol. II
    at 214-15. Similarly, Rich Feller testified that the only reason he heard given to
    plaintiff for the disciplinary action related to the claimed weight violation.       
    Id. Vol. I
    II at 396. Garner was made aware of the Olympic team variance only days
    after the incident. Yet, even during her deposition, Garner first stated it was a
    safety violation for plaintiff to allow the forty-two pound box to remain on board
    because of United’s eleven-pound weight limit for ammunition.            
    Id. Vol. I
    I at
    286-87. Under further questioning, however, Garner conceded that the box was
    permitted on board under United’s Olympic team variance, and that there was no
    violation of the weight limit.    
    Id. at 297.
    Although the evidence indicates that United focused exclusively on the
    package’s weight during its investigation, and never gave plaintiff a specific
    reason for her demotion, Garner gave new, specific reasons for demoting plaintiff
    after plaintiff filed her complaint. Garner testified during her deposition that
    plaintiff failed to ask the passenger for identification or to get documentation of
    United’s weight variance; failed to obtain “hazardous material” paperwork for the
    box; was required to verify that the box did not contain hazardous materials by
    some means other than simply asking the passenger--such as by opening it and
    visually inspecting its contents or by asking the passenger to open it; and that she
    lacked authority to remove the hazardous material sticker from the box.
    -13-
    Appellant’s App. Vol. II at 287, 290-92. Yet, United’s motion for summary
    judgment did not claim that any of these specific explanations offered by Garner
    during her deposition were, in fact, why United demoted plaintiff. United cited
    these reasons for the first time in its reply brief to the motion for summary
    judgment. Even on appeal, United never claims these specific explanations
    constitute its legitimate nondiscriminatory reason for demoting plaintiff.
    Although United states in its recitation of the facts that plaintiff failed to obtain
    verification of the passenger’s identification and did not open the box to verify its
    contents before removing the hazardous material sticker, it does not claim that
    these actions violated any of United’s rules or policies. A rational factfinder
    could conclude from United’s subjective and shifting explanations that its
    proffered justification for demoting plaintiff is false.
    Moreover, plaintiff presented additional evidence that Garner’s
    explanations are false and that all of plaintiff’s actions with respect to loading the
    second package were permitted under United’s rules and normal practices. With
    respect to the claim that plaintiff was required to check the passenger’s
    identification and verify that he was a member of the Olympic shooting team,
    Feller testified that this issue never came up during the investigation.   
    Id. Vol. I
    II
    at 396. Further, United does not dispute that the passenger had already been
    identified by other United employees when plaintiff arrived at the boarding gate
    -14-
    to interview him. United does not dispute that the weight variance was on file
    with United and listed on the passenger’s PNR on United’s computer, nor does it
    claim plaintiff was required by any rule or policy to verify independently the
    passenger’s identification.
    With respect to verifying the contents of the box and removing the
    hazardous material label, Garner conceded during her deposition that there is no
    United rule requiring plaintiff to have opened the box in order to verify its
    contents. 
    Id. Vol. I
    I at 290-91. Although Garner claimed that plaintiff was not
    permitted to remove the sticker from the box herself, and that only the shipper can
    remove the label, she was unable to point to any rule in support of this claim and
    acknowledged that United’s rules state that items offered as baggage with a
    hazardous material label are required to have the label removed if the contents are
    not dangerous.   
    Id. at 307-08.
    United’s safety policies provide that a hazardous
    material label should be removed if the contents are not dangerous.           
    Id. at 232-33;
    Vol. III at 448-49. Plaintiff testified that she was taught that it was a ramp team
    leader’s responsibility to remove a hazardous material label if the contents were
    not hazardous.   
    Id. Vol. I
    I at 216-17.
    Rich Feller testified that it is normal practice for ramp team leaders to
    ascertain the contents of a package by simply asking the passenger what is inside,
    and that it is not normal practice to open a package to check its contents.        
    Id. -15- Vol.
    III at 374-75. He testified that if a package has a hazardous materials label
    on it, United’s rules do require a ramp team leader to ascertain what is in the
    package, but permit any number of methods for doing so, including interviewing
    the passenger and asking him or her what is inside the box, checking with the
    terminal where the package was originally boarded, or opening the box.         
    Id. Vol. I
    at 135-36, Vol. III at 375-76, 379-81. Walt Harris, an operating ramp manager
    since 1984 and a ramp team leader since 1974 testified that, to his knowledge, a
    team leader could verify the contents of a package marked with a hazardous
    materials label by verbal discussion with the passenger and that there is no
    requirement that the team leader open the box.       
    Id. Vol. I
    II at 435, 438-39.
    Michael Pijanowski, a ramp safety instructor for six years, testified that he
    was trained that a ramp team leader was supposed to remove a hazardous
    materials label if the package was verified as not being dangerous, and that he
    teaches ramp team leaders that they can remove the label if they discuss the
    contents of the box with the customer.    
    Id. at 456-58.
    He testified that it is
    regular, everyday practice to take the passenger’s word for what is in a package.
    
    Id. at 459-60.
    Pijanowski testified that he has never been instructed that a ramp
    team leader must open such a package in order to verify its contents; indeed, that
    he has been instructed not to open such a package.       
    Id. Thomas Hushion,
    a ramp
    team leader for fourteen years, testified that it was routine procedure for ramp
    -16-
    team leaders to remove a sticker on a package if the passenger said the sticker did
    not match the contents, and that he was not aware of any United requirement that
    ramp team leaders open a package to verify its contents unless he or she was
    suspicious of the passenger’s answers.     
    Id. at 417-20.
    Even Peterson, who filed
    the report on the August 13 incident, testified it was his understanding that ramp
    team leaders could remove labels if they did not match the contents.       
    Id. Vol. I
    I at
    349.
    Plaintiff also presented evidence that it was not United’s normal practice to
    demote a ramp team leader for a safety violation. It is undisputed that no ramp
    team leader has ever been demoted for a safety-related violation. Peterson
    testified that in his experience, ramp team leaders improperly load radioactive or
    hazardous material onto a plane approximately once every two weeks, and that
    United’s only discipline is to talk to the ramp team leader about the problem.       
    Id. at 341-43.
    Feller testified that United’s demotion of plaintiff was the most severe
    discipline he had ever seen during his employment for a violation of this nature,
    compared to many similar incidents of which he was aware.         
    Id. Vol. I
    II at
    391-92. Feller testified that he was aware of numerous ramp team leaders who
    had exercised poor judgment with respect to safety-related matters and that it was
    United’s normal practice to simply talk to the ramp team leader about the
    problem, or require them to take additional retraining.     
    Id. at 385-86,
    400-01.

    Pijanowski, the ramp safety instructor, testified that he filed a safety report and
    brought to United’s attention, on “almost a daily basis for a long time,” the fact
    that numerous male ramp team leaders were parking motorized vehicles directly
    under the vents in the wings of aircraft during the refueling operation.    
    Id., Vol. III
    at 463-64. He testified that is a very serious safety violation that could
    result in an explosion, but that Garner told him she was ordering the ramp team
    leaders be briefed about the problem, and that none of the ramp team leaders were
    ever disciplined for this violation.   
    Id. at 463-65.
    In sum, contrary to the standard applied by the district court in evaluating
    plaintiff’ s evidence, a jury may infer discriminatory animus from “the simple
    showing of pretext,” and it may find illegal discrimination upon a prima facie
    case and pretext.   Randle , 69 F.3d at 451. Further, plaintiff produced sufficient
    admissible evidence of “weaknesses, implausibilities, inconsistencies,
    incoherencies, [and] contradictions” in United’s proffered reasons for demoting
    her and excluding her from all management positions for a reasonable factfinder
    to reject United’s explanation for demoting her, and hence infer that United did
    not act for the asserted non-discriminatory reasons.      Morgan , 108 F.3d at 1323;
    see also Reeves , 120 S. Ct. at 2109. Thus, the district court erred in granting
    summary judgment in United’s favor on plaintiff’s Title VII claim of gender
    discrimination.

    C. Retaliation Claims
    Plaintiff also claims that she was demoted from all management jobs in
    retaliation for her complaints of gender discrimination. Title VII retaliation
    claims are analyzed under the same   McDonnell Douglas burden-shifting analysis,
    and, thus, to establish a prima facie case of retaliation, plaintiff must show that:
    1) she was engaged in protected opposition to Title VII discrimination, 2) she was
    subject to adverse employment action, and 3) there is a causal connection between
    the protected opposition and the adverse employment action.      Kelley v. Goodyear
    Tire & Rubber Co ., 
    220 F.3d 1174
    , 1179 (10th Cir. 2000).
    We conclude that plaintiff has failed to make out a prima facie case of
    retaliation. As support for her retaliation claim, plaintiff points to her remark to
    Gonzales during the ammunition package investigation that she hoped the
    proposed disciplinary action was not an example of disparate treatment. Her
    statement was immediately followed by Gonzales’ decision to demote plaintiff not
    just from safety-related management positions, as recommend by Garner, but from
    all management positions. Complaints to management, even informally, can
    under some circumstances be sufficient to invoke the participation clause.
    Jeffries v. Kansas , 
    147 F.3d 1220
    , 1231 & n. 9 (10th Cir. 1998). Plaintiff’s
    isolated remark that she hoped this was not an example of disparate treatment
    falls short, however, of being considered protected conduct. Her statement was
    -19-
    simply a conclusory remark, without sufficient detail for Gonzales or United to
    know what to investigate. Thus, the district court correctly granted summary
    judgment in favor of United on plaintiff’s Title VII retaliation claim.
    AFFIRMED in part, REVERSED in part, and REMANDED for further
    proceedings consistent with this order and judgment.
