    No. 19-1268
    MARK BRADER,
    Plaintiff, Appellant,
    v.
    BIOGEN INC.,
    Defendant, Appellee.
    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF MASSACHUSETTS
    [Hon. Douglas P. Woodlock, U.S. District Judge]
    Before
    Lynch, Lipez, and Thompson,
    Circuit Judges.
    Jeremy Y. Weltman, with whom Matthew F. Renna and Hermes,
    Netburn, O'Connor & Spearing P.C. were on brief, for appellant.

    Lewis P.C. were on brief, for appellee.
    December 18, 2020
    THOMPSON, Circuit Judge.        Plaintiff-appellant Dr. Mark
    Brader appeals the district court's award of summary judgment to
    his   former   employer,   defendant-appellee    Biogen,     Inc.,   on   his
    claims of disability discrimination and retaliation in violation
    of the Americans with Disabilities Act, 
    42 U.S.C. §§ 12101-12213
    (2009) ("ADA"), and its Massachusetts analog, Mass. Gen. Laws ch.
    151B, § 4 ("Chapter 151B").1     Relevant to the instant appeal, the
    district court found that certain alleged discriminatory treatment
    Brader    experienced   during   his     employment   fell    outside     the
    applicable statute of limitations and no equitable exceptions to
    the limitations period applied.        See Brader v. Biogen Inc., 
    362 F. Supp. 3d 25
    , 38-40 (D. Mass. 2019).        After whittling the timeline
    of alleged actionable conduct to events that occurred within the
    limitations period, the district court concluded, as is relevant
    to our work on appeal, that the undisputed material facts did not
    raise a reasonable inference of employment discrimination under
    federal or state law.      Seeing no reversible error, we affirm.
    I.   GETTING OUR FACTUAL BEARINGS
    We rehearse the facts in the light most favorable to
    Brader (the nonmovant), resolving all reasonable inferences in his
    favor, consistent with record support.          See Maldonado-Cátala v.
    1   The district court also dismissed Brader's state common
    law claim for negligent infliction of emotional distress. Brader
    is not challenging this aspect of the district court's summary
    judgment ruling on appeal.

    of Brader's factual assertions is necessary to understanding his
    claims on appeal and our resolution thereof, we beg the reader's
    patience as we plow ahead.
    Biogen   is   a   pharmaceutical      company   that   develops,
    markets, and manufactures therapies for people living with serious
    neurological, autoimmune, and rare diseases.              Biogen's employees
    are governed by the company's Values in Action Code of Business
    Conduct, Non-Discrimination and Non-Harassment Policy, and its
    Americans       with    Disabilities       Act      Non-Discrimination    and
    Accommodation        Policy,    which    together     memorialize    Biogen's
    commitment      to   maintaining   a    harassment,     discrimination,   and
    retaliation free work environment.2
    Brader, a pharmaceutical scientist by trade, worked for
    Biogen from October 8, 2007 until his termination on November 6,
    2015.       At all times relevant to this appeal, Brader was employed
    as a principal scientist within Biogen's Protein Pharmaceutical
    Development ("PPD") group, i.e., a group that develops new drug
    2 Biogen has also implemented a Global Investigations
    Protocol,   which   sets    forth   procedures   for reporting,
    investigating, and disciplining employee misconduct.

    candidates for Biogen.      Brader reported to Dr. Andrew Weiskopf,
    one of PPD's directors.        Weiskopf, in turn, reported to Jessica
    Ballinger, the Senior Director responsible for PPD.           Ballinger's
    supervisor,   Dr.   Alphonse    Galdes,   served   as   the   Senior   Vice
    President of the Technical Development department.
    Nearly seven years into his employment at Biogen, on or
    around June 30, 2014, Brader experienced what he has described as
    an "acute mental episode."       Because the events leading up to and
    surrounding Brader's mental health crisis provide the landscape
    for our review of his claims on appeal, that's where we begin our
    recap of relevant events.
    A.    Brader's June 2014 Presentation and Performance Review
    On June 18, 2014, Brader presented his research on
    "recent advances in the measurement and interpretation of protein
    conformational stability" at a routine PPD meeting attended by
    senior management.     Brader viewed his presentation as an important
    opportunity for his career because he believed he was being
    considered for a mid-year promotion to director in the "June/July
    [2014] time frame."3
    3    According to his previous performance evaluations,
    Brader was considered a "solid" employee, who had made "outstanding
    contributions" to PPD's advancement of new technologies.
    - 4 -
    Handwritten notes from Brader's employee file,4 dated
    September 2, 2014, suggest that he was on a mid-year "promotion
    list" compiled on or around June 16, 2014,5 and that a "promotion
    meeting" convened by Galdes took place on June 19, 2014 (the day
    after Brader's presentation).6
    On the same day as Galdes' promotion meeting, Dr. Mariana
    Dimitrova (a director in PPD) sent an email to Brader's immediate
    supervisor, Weiskopf, and PPD's senior director, Ballinger, in
    which       she    expressed   concerns   about   Brader's   presentation   and
    underlying research.            In her email, Dimitrova criticized the
    accuracy, complexity, and impact of Brader's research, and she
    suggested that his presentation did not align with PPD's vision,
    4 The handwritten notes were penned by Andrea Sinclair
    (PPD's designated HR professional at the time) during a
    conversation with PPD senior management prior to Brader's return
    to work after medical leave (which we'll discuss in detail later).
    5 The record does not indicate who composed the promotion
    list, nor does it contain the identities of other PPD employees
    who, like Brader, were being considered for a mid-year promotion.
    6 The record does not divulge any information about
    Galdes' agenda for the meeting or the meeting's other attendees.
    The record also does not indicate whether Galdes (or anyone else)
    made a decision regarding Brader's mid-year promotion prospects on
    that day. At best, Biogen asserts (and Brader disputes) that PPD
    senior management, including Galdes and Ballinger, decided not to
    promote Brader at some point after his PPD presentation on June
    18, 2014 and prior to his acute mental health episode on or around
    June 30, 2014. Ballinger testified that Brader was not promoted
    during Biogen's mid-year promotion process in 2014 because he had
    not yet "demonstrated his capability in a director level." The
    record does not specify whether (or when) Biogen told Brader about
    its 2014 decision not to promote him.

    platform, and "core capabilities."             Weiskopf emailed in response
    that he agreed with "much of" Dimitrova's concerns and promised to
    "share his thoughts" with Brader during their one-on-one mid-year
    performance meeting scheduled for the next day.
    As planned, Weiskopf and Brader met to discuss the
    latter's    evaluation.        During    the    meeting,      Weiskopf   leveled
    criticism at Brader's presentation to PPD.              Weiskopf called the
    presentation      "terrible"     and     denounced      the     "harmful"      and
    inappropriate "views and agenda" espoused therein. As Brader tells
    it, Weiskopf did not provide any "constructive" feedback during
    their hour-long meet-up; instead, he intentionally "taunt[ed]"
    Brader with "nonsensical" criticism of his presentation.                 Because
    Brader felt there was "no good reason" for Weiskopf's harsh
    critique, he left their meeting feeling confused and upset.
    A few days later, on June 24, 2014, Brader emailed
    Weiskopf    to   express   his   concerns      about   the    feedback   he    had
    received.    Brader stated that he did not understand why Weiskopf
    had an issue with the "views and agenda" underlying his "clearly
    technical    presentation."        Brader       also   described      Weiskopf's
    feedback as "troubling" and abnormal by Biogen's standards.                    He
    then requested another one-on-one meeting with Weiskopf so he could
    better   understand    Weiskopf's       perspective.         Brader   noted,    in
    addition, that he would be reaching out to Ballinger (Weiskopf's
    direct supervisor) for "help" as well.            Weiskopf obliged Brader's
    - 6 -
    meeting request, and the pair agreed to convene again a couple
    days later.
    According to Brader, during the follow-up meeting on
    June 26, 2014, Weiskopf again called his presentation "terrible"
    and also "insult[ing]," which Brader believed was "inappropriate."
    Nevertheless, the next day, Brader thanked Weiskopf via email for
    meeting with him again and stated that he planned to ask Ballinger
    for feedback "soon."
    Then, on Sunday, June 29, 2014, Brader emailed Weiskopf
    again, seeking "a few minutes" of his time in order to resolve
    what Brader described as the "feedback matter." Weiskopf suggested
    that Brader meet him in his office during business hours the next
    morning.   Less than ten minutes after emailing Weiskopf, Brader
    sent a separate email to Ballinger with the subject line "utmost
    importance and private." In the body of his email, Brader reported
    that he and Weiskopf had had a "very robust conversation" about
    his   mid-year   performance   evaluation,    and   he   asked   whether
    Ballinger was able to meet with him the next day to provide her
    perspective on Weiskopf's feedback.     Brader concluded his email to
    Ballinger by stating that he could perhaps resolve the "whole
    'misunderstanding'"    by   deploying   his   "Ghandi"-like      conflict
    management skills.
    Several hours later, Brader (coincidentally) ran into
    Ballinger on a walking path in their shared neighborhood.         Brader
    - 7 -
    and Ballinger paused their respective walks to catch up with one
    another on life outside of work.            According to Ballinger, as their
    conversation progressed, she became concerned that something was
    off   about       Brader.       Ballinger        testified     that    Brader      was
    uncharacteristically "stressed," "agitated," and "not himself."
    Later that night, Ballinger responded to Brader's email request
    for a meeting from earlier that day.              She explained to Brader that
    she was aware of his discussions with Weiskopf and presumed there
    was a "big misunderstanding."             She agreed to meet with Brader on
    Monday, June 30, 2014, and she advised him not to stress about
    Weiskopf's feedback in the meantime. Ballinger forwarded her email
    correspondence with Brader to Weiskopf along with a recommendation
    that they also meet given Brader's "strangely written" email.
    Ballinger testified that Brader's odd behavior and email prompted
    her to alert HR when she returned to work on Monday.
    B.    Brader's Safety Concerns
    On    Monday     morning,    June    30,   2014,      Brader   went    to
    Weiskopf's    office     as     scheduled    to    rehash    his    objections     to
    Weiskopf's criticism.          This time around, according to Brader, he
    demanded   that      Weiskopf    "stop    harassing"     him    and   objected     to
    Weiskopf's        "inappropriate    and     untruthful       criticism"     of     his
    presentation.         Weiskopf     purportedly       disagreed      with    Brader's
    characterization of his conduct and feedback. At some point during
    the meeting, Brader excused himself and returned a few minutes
    - 8 -
    later with two colleagues7 because (pursuant to his deposition
    testimony)    he    "didn't     feel     safe,"    believing    Weiskopf        was
    "deliberately      targeting"    and    humiliating      him   as   part   of    a
    "malicious personal issue or vendetta."8                Brader also testified
    that he was concerned for his physical safety because of Weiskopf's
    "body language," "hostile persona," and unwillingness to change
    his opinion on Brader's presentation.9
    Ballinger, as requested, met Brader later that day at a
    Starbucks    on    Biogen's   campus.10        Brader   denounced    Weiskopf's
    7    At his deposition, Brader identified these colleagues as
    "Olivia Henderson and Pinky," and he asserted that Biogen knew
    their identities, but never interviewed them. As best we can tell,
    we never hear from these two colleagues in discovery, so the record
    is silent as to their take on what they observed during this
    meeting between Brader and Weiskopf and silent as to whether Biogen
    ever reached out to them.
    8    Brader testified further that Weiskopf treated him
    differently than he did other Biogen employees in one-on-one
    meetings.   When asked to elaborate, Brader stated:     "What was
    different is that his criticism of me and the issues that he
    insisted on discussing with me were clearly preposterous and
    absurd." In addition, given Weiskopf's perceived "hostile" and
    irrational attitude during meetings with Brader, Brader surmised
    that his supervisor was deliberately humiliating and antagonizing
    him in order to provoke him into an "angry response."
    9    The record does not indicate whether Weiskopf was
    deposed and contains no evidence from which we can discern
    Weiskopf's take on his communications with Brader during the
    relevant time period. Regardless, as we have explained, we recite
    the undisputed material facts in the light most favorable to
    Brader, the nonmoving party.
    10   To prepare for her meeting with Brader, Ballinger
    (unbeknownst to Brader) reached out to Sinclair (PPD's assigned HR
    professional) for guidance. According to Ballinger, Sinclair was
    concerned for Ballinger's safety and advised her against meeting
    - 9 -
    criticism     as     having    "cross[ed]      the     line"       into   harassment
    territory.     He then made a "formal complaint that [Weiskopf's]
    conduct     toward    [him]     violated    Biogen's        harassment     policy."
    According to Brader, Ballinger did not seem to be taking his
    expressed complaint seriously.
    Ballinger's account of their meeting differs markedly
    from Brader's:       he appeared, she recalled, "physically agitated"
    and "fidget[y]," and his speech was "jumbled."                 Although Ballinger
    had trouble deciphering what she described as Brader's "word
    salad," she believed Brader repeatedly said he had safety concerns
    and great ideas.      Ballinger testified, however, that Brader didn't
    provide any pertinent details about his ideas, safety concerns, or
    Weiskopf's criticism.         Based on the information she received from
    Brader (to the extent she could discern it), she struggled to
    understand why he felt unsafe at work.
    Toward the end of their hour-long conversation, Brader
    handed    Ballinger     a     crumpled   piece    of       paper    containing   his
    indecipherable handwritten notes.           Before they went their separate
    ways, Ballinger suggested that Brader contact Biogen's Employee
    Assistance    Program       ("EAP")   regarding      his    safety    concerns   and
    handed him an information sheet about the program's resources.
    with Brader in person.     Sinclair eventually took the lead on
    crafting Biogen's internal strategy for communicating with and
    supporting Brader over the next two days.
    - 10 -
    After        their    meeting,    Ballinger      contacted   Sinclair      to    discuss
    Brader's       grievances       and   her     observations   about   his    behavior.
    Ballinger testified that she was afraid for Brader's wellbeing.
    That    evening,   Brader    sent    Ballinger,   Weiskopf,       and
    Sinclair increasingly incoherent emails in which he expressed his
    frustration with Weiskopf's feedback, declared that he was not
    safe at work, and demanded to speak to HR about his concerns as
    soon as possible.            In her responsive email, Ballinger urged Brader
    to contact the EAP's 24/7 confidential hotline about his safety
    issues and recommended he work from home the next day.                          She also
    noted that HR (i.e., Sinclair) would be reaching out to him
    directly.           In a separate email to Brader, Sinclair proposed that
    Brader utilize the EAP hotline to speak to someone that night, and
    she encouraged him to work from home the next day.11                  Sinclair also
    offered to call Brader again so that she could hear more about
    what was troubling him.
    Working from home late that night and well into the next
    day, July 1, 2014, Brader sent numerous unintelligible and rambling
    emails        to     his    colleagues   and     supervisors,     including       Galdes
    (Ballinger's          boss),     in   which    he    complained   about    Weiskopf's
    criticism, stated that he did not feel safe, and revealed his
    11Unbeknownst to Brader, given his behavior, Sinclair,
    Ballinger, and others requested that security suspend Brader's
    access to Biogen's campus on July 1, 2014. Campus security also
    was asked to prevent Brader from entering any Biogen buildings.
    - 11 -
    burgeoning concerns about his mental health.                 During a respite
    from his email campaign, Brader spoke with Sinclair over the phone.
    Given her role as PPD's HR person, Sinclair was responsible for
    overseeing    HR's    response     to   Brader's    safety    remonstrations.
    Brader testified that, at some point in his conversation with
    Sinclair, he made a "formal complaint of harassment against Dr.
    Weiskopf" and a complaint against Ballinger for being dismissive
    of his concerns regarding Weiskopf's harassment.             Brader claims he
    told Sinclair that Weiskopf and Ballinger had violated Biogen's
    "core values:      honesty, integrity and respect for others."         Brader
    says    Sinclair    refused   to    acknowledge     that   he   was   formally
    complaining about violations of Biogen policy during their call.
    According   to   Sinclair's     contemporaneous      handwritten
    notes from her July 1, 2014 phone conversation with Brader, he
    implored Sinclair to:      (1) send an email to Biogen's CEO; (2) make
    sure Ballinger spoke to Weiskopf; and (3) survey PPD employees
    about their experiences in the group.12            Notwithstanding Brader's
    assertions during their call, Sinclair testified she was not able
    to ascertain the basis of Brader's safety-at-work fears.               Before
    12 Sinclair's notes indicate (without elaboration) that
    Brader complained about Weiskopf's ineffective feedback and
    failure to "do the right thing." The notes also say Brader accused
    Ballinger and Weiskopf of calling him "crazy," and Ballinger and
    Dimitrova of "kicking a guy when he's down." In addition, as best
    we can discern from the notes, Brader told Sinclair he had been
    experiencing mental health issues since at least February 2014.
    - 12 -
    the end of their conversation, Sinclair encouraged Brader to
    contact the EAP about his safety worries.    Again.
    Later that day, Brader's wife called Sinclair to thank
    her for giving Brader information on Biogen's EAP, and explained
    that Brader had been hospitalized.     Brader began a medical leave
    of absence from Biogen that day.
    On July 7, 2014, from a hospital bed, Brader emailed
    George Scangos (Biogen's CEO), Weiskopf, Galdes, at least five
    other Biogen employees, and his wife.     The email's subject line
    was "Oliver and the trouble with Death Stars -email#00."     Brader
    stated in the body of the email that he was scared and needed help
    escaping a "medium security mental hospital" where he was receiving
    treatment at the time.    Brader also shared his desire to "Fix
    What's Wrong with PPD."   The email made no mention of Weiskopf's
    inappropriate feedback or Ballinger's alleged failure to take his
    complaints seriously.
    Between June 30 and July 7, 2014, Sinclair, Weiskopf,
    and Ballinger had several in-person meetings, teleconferences, and
    email exchanges about how to respond to Brader's safety concerns.
    In addition, Galdes, unspecified members of Biogen's in-house
    legal team, and campus security discussed Biogen's strategy for
    ensuring that Brader did not harm himself or others on Biogen's
    campus.   There is no indication that Biogen initiated a formal
    internal investigation into Brader's complaints of harassment
    - 13 -
    against Weiskopf at any point.13            When asked whether Biogen's
    policies   required   her   to   conduct    an   investigation   under   the
    circumstances presented, Sinclair testified that Brader's "unique"
    situation required (at minimum) that HR communicate with Brader's
    supervisors, the EAP, legal, and campus security (which Sinclair
    did).14
    C.   Brader's Medical Leave:         July 2014 - October 2014
    In 2014, Biogen had a procedure in place to handle
    employee medical leaves that was overseen by a third-party vendor.
    Such was the case on July 1 when Brader began his leave following
    the onset of his acute mental health episode.         So, as Biogen tells
    it, because of this firewall protocol, PPD senior management,
    including Weiskopf, Ballinger, and Galdes, never received any
    information   from    Brader's   healthcare      providers   regarding   his
    medical condition or what caused it.
    Biogen's HR department did get one direct update on
    Brader's health condition after his leave began. On July 20, 2014,
    13   Sinclair testified that, during the relevant time
    period, HR personnel were tasked with determining whether to refer
    an   employee's  complaint   to   "employee   relations"  for   an
    investigation.
    14    According to Biogen's Non-Discrimination and Non-
    Harassment Policy, Biogen pledges to "respond promptly to all
    reported complaints and conduct an investigation in a fair and
    expeditious manner."   Investigations "may include an interview
    with the person filing the complaint and with witnesses, if
    appropriate," as well as an interview with the employee "alleged
    to have committed the" misconduct.
    - 14 -
    Brader's wife (unprompted by anyone at Biogen) emailed Sinclair
    and Weiskopf to pass along Brader's diagnosis and prognosis.            She
    explained the doctors believed he had contracted an "infection"
    and, consequently, suffered an "acute reaction to the medications"
    he was prescribed after back surgery in April 2014.           Ms. Brader
    expressed relief that Brader's condition was "temporary."
    On September 10, 2014,       Brader's healthcare provider
    completed the Healthcare Provider Disability and Accommodation
    Questionnaire Biogen sent to the Braders for completion.                The
    provider described Brader's condition as a non-permanent physical
    or mental impairment that began "following back surgery" in April
    2014.    When asked to explain Brader's impairment, his provider
    wrote:      "[Brader]   currently   is   limited   in   his   ability    to
    concentrate, focus on tasks, interact confidently [with] co[-]
    workers."    Even so, the provider indicated that Brader would not
    require any job accommodations upon his return to work and could
    perform his job with "no restrictions expected."          Brader claims
    that he sent the completed questionnaire to Heather-Lee Brown, an
    HR professional at Biogen.     There is no indication in the record
    that Brader's supervisors reviewed the questionnaire or learned
    any information from providers regarding his medical condition at
    - 15 -
    any time relevant to this appeal or from Brader following his
    "Death Star" email.
    D.   Brader's Return to Biogen in October 2014
    In October 2014, Brader returned to work on a part-time
    schedule (at his request).    Brader did not ask for or receive any
    other accommodation or changes to the conditions of his employment
    at Biogen upon his return.         Accordingly, his position, primary
    responsibilities, supervisor, and compensation were the same as
    before.    Relevant here, however, Brader learned that a research
    project he once led in collaboration with Avia Biosystems, Inc.
    had been reassigned to another team while he was out on leave, and
    he would not be involved in the project going forward.        Moreover,
    Brader's post-doctoral student had been tasked with taking over at
    least part of Brader's responsibilities on the Avia project.
    Brader's next several months at Biogen (between November
    2014 and February 2015) were without incident relevant to this
    appeal, according to the record.         Importantly, Brader does not
    allege that he was harassed by Weiskopf or felt unsafe at work,
    nor does he claim he experienced any other discriminatory or
    retaliatory acts during this time.
    E.   The Crystallization Project
    By March 2015, Brader was exploring a "crystallization
    concept"   he   believed   would     help   accelerate   Biogen's   drug
    manufacturing process while reducing production costs.       In a March
    - 16 -
    16, 2015 email, Brader asked Ballinger whether her boss, Galdes,
    would be willing to "convene a director-level staff meeting" in
    which        he    could   share    "provocative/transformative    technology
    ideas."           Ballinger responded by asking Brader to let her and
    Weiskopf review it first and provide guidance on next steps.
    On April 3, 2015, Brader sent an email to Galdes,
    Ballinger, and others (but not Weiskopf) regarding his desire to
    lead a conversation on "new innovative possibilities" for protein
    crystallization.           Several days later, on April 7, 2015, Brader
    emailed Weiskopf and Ballinger seeking their internal support for
    his "highly novel" crystallization concept.                Brader asked that
    Weiskopf          and   Ballinger   "champion"   his   research   proposal   by
    allowing him to lead a discussion at a "director-level forum" and
    draft a white paper regarding his research.                 Weiskopf, in his
    responsive email, stated that Brader's crystallization concept was
    "innovati[ve]," but expressed concern with Brader's approach to
    soliciting support for this research proposal.                Weiskopf asked
    Brader not to share his proposal with senior leaders outside of
    PPD (as Brader had done on April 3, 2015)15 until after he and
    Brader could meet one-on-one.
    Brader testified that at some point in April 2015 he
    complained to Ballinger about Weiskopf's "disingenuous" response
    15Weiskopf purportedly disagreed with Brader's decision to
    announce his nascent crystallization concept via email to Galdes
    - 17 -
    to his crystallization concept.         Brader purportedly told Ballinger
    that Weiskopf had admonished him for "trying too hard" at work and
    asking too many questions in meetings and presentations.
    Anyway, Brader was given the greenlight to present his
    work on the crystallization concept to directors in Biogen's
    Strategic Innovation group on June 2, 2015.16            By the end of July
    2015, Biogen's Strategic Innovation group had expressed interest
    in   helping    Brader      develop     a     research   strategy   for    the
    crystallization concept.       Ballinger though, citing concerns about
    Biogen's   financial       stability    and     the   Technical   Development
    department's budget and priorities at the time, advised Brader via
    email to seek guidance from the business development team before
    taking additional action on his research proposal.
    F.   Brader's 2015 Mid-year Review
    The approach of July 2015 meant it was time for Brader
    to   receive   his    mid-year,    written     performance   evaluation   from
    Weiskopf. In it, Weiskopf wrote, as part of his overall assessment
    of Brader, that Brader's "project goals and results" were on track.
    He noted, however, that there were documented concerns about
    Brader's "behavior."         Unidentified peers and stakeholders had
    and others     without     first    seeking     Weiskopf's   or   Ballinger's
    approval.
    16  Weiskopf was copied on the email invitation to Brader's
    presentation, but it is not clear from the record whether he
    attended.
    - 18 -
    observed    Brader    being       "dismissive"      and    "confrontational"        in
    response to suggestions and feedback he received in group meetings.
    In     addition,     according       to     his    evaluation,        although     the
    crystallization concept initially was well-received, Brader was
    experiencing difficulty moving the project forward due to a "clear
    disconnect" between his objectives and stakeholders' expectations.
    Brader testified that Weiskopf's criticism of the crystallization
    concept was "disingenuous" given Weiskopf's lack of professional
    expertise on the subject matter, and he also stated that Weiskopf's
    criticism owed to "professional jealousy" and "desire to take undue
    credit" for Brader's work.
    On July 31, 2015, Brader, again ascending the corporate
    food    chain,     emailed      Ballinger    to    complain     about      Weiskopf's
    "performance expectations" and failure to foster a supportive
    environment; although he did "not question[] the veracity of
    [Weiskopf's] feedback," he did question Weiskopf's "consistency in
    communicating and administering clear goals and expectations with
    metrics of success associated with them."                  Brader explained that
    Weiskopf's reasons for criticizing his "poor performance" and
    "ineffective scientific leadership" were poorly articulated and
    his    expectations       for    Brader   lacked    clarity.          He   asked   for
    Ballinger's help ensuring that Weiskopf was "held accountable for
    his    feedback"    and    the    expectations      he    set   for   his   reports.
    Ballinger eventually responded to Brader's email, encouraging him
    - 19 -
    to work with Weiskopf to find a constructive resolution of their
    issues "on both sides."          Then, in response to an August 11, 2015
    email from Brader containing suggestions on how Weiskopf could
    improve      his   "managerial     effectiveness,"      both    Ballinger    and
    Weiskopf responded, with Weiskopf stating he was "committed to
    working together with [Brader] to help him be successful and to
    strengthen [their] working relationship." Additionally, Ballinger
    met   with    Brader    on   September   29,   2015,   and   listened   to   his
    complaints about his 2015 mid-year review, which he described as
    inaccurate.        Brader did not raise harassment or discrimination
    allegations as the motivator for the "inaccuracies."
    G.   Brader's Termination and Aftermath
    Meanwhile, back on August 6, 2015, Galdes, as part of
    Biogen's     company-wide     reduction-in-force       (known   internally   as
    Gemstone) received instructions to compile a list of employees to
    lay off from the Technical Development department.17              Gemstone was
    part of a larger internal effort by Biogen to restructure and
    redefine its priorities as a company.                  According to Biogen,
    Gemstone's objectives included:           eliminating positions that did
    17  Galdes was part of a small team across Biogen's
    departments that helped coordinate a major restructuring of the
    company in 2015. The team -- made up of twenty people out of an
    eight-thousand-person worldwide workforce -- included other senior
    vice presidents at Biogen and representatives from HR. The record
    does not indicate who, in particular, directed Galdes to identify
    employees from his department for termination.
    - 20 -
    not   reflect   an   investment    in    Biogen's    critical      priorities;
    consolidating duplicative work streams; and redefining employee
    roles and responsibilities.
    By no later than September 9, 2015, Galdes had decided
    to recommend Brader for termination along with twenty-four other
    employees    from    PPD   and   other   groups     within   the     Technical
    Development department.      Brader alleges he was the only principal
    scientist on the Gemstone list.          Galdes testified that, at the
    time, he believed Brader was an appropriate candidate for the
    reduction-in-force because Biogen was no longer prioritizing and
    investing in the "Blue Sky" innovation work that Brader was
    responsible for in PPD.18        Moreover, based on his conversations
    with Brader and his understanding of Biogen's priorities post-
    restructure, Galdes believed that Brader's exploration of novel
    methodologies for protein crystallization was "speculative and
    would take a long time to prove."           For similar reasons, Galdes
    also decided to include Brader's post-doctoral research student in
    the upcoming layoffs.        In reaching this decision to terminate
    Brader, says Galdes, one that was his alone for the PPD group, he
    18  Pursuant to Brader's self-reporting on his 2015 mid-year
    evaluation, new technology advancement and innovation represented
    15% of Brader's work, and, as Brader described it, his remaining
    responsibilities were divided up as follows:     support Biogen's
    existing "subvisible particle" projects (35%); supervise post-
    doctoral student (25%); manage external technology projects and
    collaborations (15%); and provide biophysical support for existing
    products (10%).
    - 21 -
    did not consult Weiskopf and Ballinger or inform them of his
    decision until it was being implemented.19     He also testified he
    did not consider Brader's "health issue" in June 2014 in reaching
    his decision.    He was not aware that Brader had (or has) an ongoing
    mental health issue.20
    In October 2015, Biogen laid off approximately 11% of
    its workforce (approximately 880 employees) as part of the Gemstone
    restructuring.     Brader learned that he would be part of the
    reduction-in-force on October 22, 2015.    When his employment ended
    on November 5, 2015, Brader filed a written complaint of workplace
    "bullying" and "retaliation" with Biogen's HR department.
    After Brader's termination, Biogen continued to work on
    protein crystallization, and Brader's workstream was assigned to
    an employee who Brader says spent approximately 20% of his time on
    the project.    Then, three months after Brader left Biogen, Biogen
    advertised new positions seeking candidates with crystallization
    experience to serve as either a senior engineer or a post-doctoral
    19   Because Galdes initially considered adding Ballinger to
    the Gemstone list, it was especially important for him to keep her
    in the dark on the process.       Ultimately, Galdes decided to
    transition Ballinger into a different role (as opposed to
    terminating her).
    20   Galdes testified he was aware Brader had experienced a
    "health issue" in late June and early July 2014. However, Sinclair
    told him in early July (based on information from Ms. Brader) that
    Brader's behavior was caused by "meningitis" resulting from
    Brader's surgery in April 2014. Galdes therefore believed Brader's
    condition in June and July 2014 was temporary.
    - 22 -
    student.   Brader and Biogen dispute whether Brader was qualified
    for either of these positions.
    On   December   23,   2015,    Brader     filed   an   employment
    discrimination and retaliation complaint against Biogen with the
    Massachusetts Commission Against Discrimination ("MCAD").             After
    receiving approval from MCAD, Brader filed suit against Biogen in
    Massachusetts Superior Court on April 7, 2016.               A month later,
    Biogen removed the case to the U.S. District Court for the District
    of Massachusetts.      According to the district court's generous
    reading of Brader's complaint, he alleges (in broad strokes) that
    Biogen discriminated and retaliated against him because of his
    disability -- including by failing to promote him, reassigning the
    Avia project, failing to investigate his complaints, permitting
    Weiskopf's incessant criticism to go unchecked, and terminating
    him -- in violation of the ADA and Chapter 151B.
    Biogen filed a motion for summary judgment on all claims
    on October 20, 2017.   The district court favorably assumed for the
    purpose of its review that Brader was a disabled (or handicapped)
    person protected under ADA and Chapter 151B during the limitations
    period.    See Brader, 362 F. Supp. 3d at 42.          The district court
    reasoned, however, that any discriminatory and/or retaliatory
    employment practices that Biogen committed prior to "spring of
    2015" fell outside the applicable statute of limitations for
    Brader's   claims,   and   concluded     that   no   equitable    exception
    - 23 -
    applied.    Id. at 37.    In other words, the district court found
    Brader's claims were time-barred to the extent they were premised
    upon alleged conduct that occurred in 2014.        When the dust settled
    on what remained of the record, the district court determined that
    the undisputed material facts did not raise a reasonable inference
    that Biogen discriminated or retaliated against Brader because of
    his disability.     Id. at 44-45.     This timely appeal ensued.
    II.     STANDARD OF REVIEW
    Our review of the district court's grant of summary
    judgment is de novo.      See Murray, 821 F.3d at 83 (citing Henry,
    686 F.3d at 54).      "A moving party is to be spared a trial when
    there is no genuine issue of any material fact on the record and
    that party is entitled to judgment as a matter of law."                  Id.
    (citing Fed. R. Civ. P. 56(a)).       To avoid "the swing of the summary
    judgment scythe," the nonmoving party must adduce specific facts
    showing that a trier of fact could reasonably find in his favor.
    See Mulvihill v. Top-Flite Golf Co., 
    335 F.3d 15
    , 19 (1st Cir.
    2003).     The nonmovant cannot rely on "conclusory allegations,
    improbable inferences, and unsupported speculation." Medina-Muñoz
    v. R.J. Reynolds Tobacco Co., 
    896 F.2d 5
    , 8 (1st Cir. 1990).
    III.   DISCUSSION
    Brader   is   appealing    the   district   court's   grant    of
    summary judgment against his ADA and Chapter 151B claims.          As best
    we can discern, Brader advances two distinct disability-based
    - 24 -
    discrimination   claims:   (A)    a   discriminatory   discharge   claim
    alleging that Biogen wrongfully terminated Brader on the basis of
    his disability, with Biogen's stated reasons for the termination
    being pretextual; and (B) a claim of disability harassment under
    a hostile work environment theory alleging a pattern of adverse
    employment actions taken against him that, in the aggregate,
    constituted a hostile work environment that culminated in and
    included his eventual termination.21
    21   To the extent Brader is asking us to consider a challenge
    that he suffered retaliatory action for having reported
    disability-based discrimination to HR and his supervisors, we put
    an end to that notion right off the analytical bat: Brader has
    not identified or developed an argument regarding any missteps
    underlying the district court's dismissal of that claim.
    To have made a retaliation case, Brader would have needed
    to prove: "(1) []he engaged in protected conduct; (2) []he was
    subjected to an adverse employment action; and (3) the adverse
    employment action is causally linked to the protected conduct."
    Rivera-Rivera v. Medina & Medina, Inc., 
    898 F.3d 77
    , 94 (1st Cir.
    2018) (citing Noviello v. City of Boston, 
    398 F.3d 76
    , 88 (1st
    Cir. 2005)). The district court explained that even if Brader had
    established protected conduct (and it wasn't sure he had), he had
    failed to present any evidence to demonstrate the requisite causal
    connection between that conduct and his termination. Brader, 362
    F. Supp. 3d at 44-45. Now on appeal, Brader still doesn't point
    to any evidence that would close this loop or demonstrate how the
    district court erred in concluding otherwise.         Brader drops
    mentions of "retaliation" in his brief but does nothing more to
    advance developed argumentation on that claim. See Rodríguez v.
    Municipality of San Juan, 
    659 F.3d 168
    , 175-76 (1st Cir. 2011)
    (deeming waived arguments offered with no citations or analysis,
    explaining, "[s]ure, he uses some buzzwords and insists that the
    judge stumbled in ruling on these claims[, b]ut he provides neither
    the necessary caselaw nor reasoned analysis to show that he is
    right about any of this"); United States v. Zannino, 
    895 F.2d 1
    ,
    17 (1st Cir. 1990) (urging that litigants are required to develop
    their own arguments rather than "leaving the court to do counsel's
    work").
    - 25 -
    And as to those claims, after careful review of the
    record, we conclude the district court did not err in determining
    Brader's discrimination charges fail.       Before we lay out the
    specifics of Brader's discrimination claims, a few preliminary
    basics of the ADA -- and Chapter 151B, the Massachusetts analog
    law -- are helpful for context.    "The ADA prohibits an employer
    from discriminating against an otherwise qualified individual
    based on a real or perceived disability."    Murray, 821 F.3d at 83
    (citing 
    42 U.S.C. §§ 12112
    , 12102; 
    29 C.F.R. § 1630.2
    ).       When a
    plaintiff brings suit advancing ADA claims, he or she "bears the
    burden of presenting evidence to establish each element under the
    particular theory of disability discrimination alleged."    
    Id.
       For
    its part, Massachusetts has similar prescriptions.22       See Mass.
    22   Specifically,    the   Massachusetts   antidiscrimination
    statute makes it unlawful for employers to "refuse to hire, rehire
    or advance in employment or otherwise discriminate against,
    because of his handicap, any person alleging to be a qualified
    handicapped person . . . ." Mass. Gen. Laws ch. 151B, § 4(16).
    The statutory definitions of "disability" under federal law and
    "handicap" under Massachusetts law are virtually identical.
    Compare 
    42 U.S.C. § 12102
    (2) (defining "disability," in relevant
    part, as "a physical or mental impairment that substantially limits
    one or more major life activities of such individual") with Mass.
    Gen. Laws ch. 151B, § 1(17) (defining "handicap" as "a physical or
    mental impairment which substantially limits one or more major
    life activities").     The Massachusetts Supreme Judicial Court
    ("SJC") consistently applies federal law in evaluating disability
    discrimination and retaliation claims.       Cherkaoui v. City of
    Quincy, 
    877 F.3d 14
    , 24 (1st Cir. 2017).
    Notwithstanding similarities in the statutes' text, we
    have recognized that the SJC has on occasion underscored the
    critical distinctions between Chapter 151B and the ADA. See, e.g.,
    Dahill v. Police Dep't of Bos., 
    748 N.E.2d 956
    , 963–64 (Mass. 2001)
    - 26 -
    Gen. Laws ch. 151B, § 4(16); see also Murray, 821 F.3d at 83
    (collecting cases).         In addressing Brader's appellate arguments,
    we evaluate the ADA claims alongside the state-law claims (our
    assessments    of    Brader's       federal    and    state-law     claims   often
    overlap).    Cherkaoui, 877 F.3d at 24 (applying federal case law in
    a discrimination case where "material differences" between the ADA
    and Chapter 151B were not relevant to the plaintiff's claims); see
    also Murray, 821 F.3d at 83.
    A. Wrongful Discharge Discrimination Claim
    Brader claims that Biogen terminated him because of his
    disability, and Biogen's stated reasoning for the termination is
    pure pretext designed to mask its discriminatory animus.                 Because
    Brader has not proffered direct evidence of a discriminatory
    discharge,    we    invoke    the    familiar    three-step       burden-shifting
    scheme outlined in McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
    ,
    802-07   (1973).      "At    the    first     stage   of   this   framework,   the
    appellant bears the burden of showing a prima facie case of
    discrimination."      Miceli v. JetBlue Airways Corp., 
    914 F.3d 73
    , 81
    (1st Cir. 2019) (citing Gannon v. City of Boston, 
    73 N.E.3d 748
    ,
    756 (Mass. 2017)).      Here the prima facie case requires a showing
    that Brader has a disability; that he was "nonetheless qualified
    (declining to adopt federal jurisprudence in evaluating Chapter
    151B disability discrimination claim concerning a "correctable"
    impairment).   But Brader does not identify any such critical
    distinctions relevant to our review of the instant appeal.
    - 27 -
    to perform the essential functions of the job, with or without
    reasonable accommodation; and that, despite the foregoing," Biogen
    discharged him.     
    Id.
     (citing Verdrager v. Mintz, Levin, Cohn,
    Ferris, Glovsky & Popeo, P.C., 
    50 N.E.3d 778
    , 793 (Mass. 2016)).
    At step two in the analysis, the burden of production shifts to
    Biogen, which must proffer a legitimate reason for terminating
    Brader.     See Lockridge v. Univ. of Me. Sys.,

    (1st Cir. 2010).   Biogen's proffered reason must be one "which, on
    its face, would justify a conclusion that the plaintiff was let go
    for a nondiscriminatory motive."        Dávila v. Corporación De P.R.
    Para La Difusión Pública, 
    498 F.3d 9
    , 16 (1st Cir. 2007).            If
    Biogen provides such a reason in this case, "the McDonnell Douglas
    framework     disappears   and    the     sole   remaining   issue   is

    685 F.3d 87
    , 93 (1st Cir. 2012)). To avoid the summary judgment scythe
    at step three of the analysis, Brader must "show by a preponderance
    of the evidence that [Biogen's] proffered reason is pretextual and
    that the actual reason for the adverse employment action is
    discriminatory."     Johnson v. Univ. of P.R.,

    Corp., 
    846 F.2d 103
    , 109 (1st Cir. 1988), the nonmoving party must
    proffer more than "conclusory allegations, improbable inferences,
    and unsupported speculation" for his claims to survive, Coll v. PB

    , 1121 (1st Cir. 1995) (quoting
    Medina–Muñoz, 
    896 F.2d at 8
    ).
    We assume favorably to Brader that he established a prima
    facie case of disability discrimination (in shorthand -- disabled,
    qualified, discharged) in violation of the ADA and Chapter 151B,
    thereby surmounting step one of the McDonnell Douglas framework.
    Turning to step two, the burden of production shifts to
    Biogen to articulate a legitimate, nondiscriminatory reason for
    terminating Brader in November 2015. On appeal, Brader says Biogen
    fell short on this requirement, while Biogen contends that it met
    its burden by demonstrating that it terminated Brader as part of
    a   company-wide        reduction-in-force        that     impacted    11%   of     its
    employees.        For    support,     Biogen      relies    upon   the   deposition
    testimony    of   Galdes      (the    sole   decisionmaker         responsible      for
    Brader's    termination)       in    which   he    clearly    explained      that   he
    selected Brader because Biogen was no longer prioritizing the "Blue
    Sky" innovation work on which Brader primarily focused.                      We agree
    with Biogen -- this evidentiary proffer was sufficient to allow a
    jury   reasonably       to   conclude    that     Biogen's    stated     reason     for
    terminating Brader was legitimate.
    - 29 -
    With that, the burden of production shifts back to Brader
    to prove Biogen's stated reason for terminating him is pretextual.
    To meet his step-three burden, Brader "must offer 'some minimally
    sufficient evidence, direct or indirect, both of pretext and of
    [Biogen's] discriminatory animus.'"          Pearson v. Mass. Bay Transp.

    understand that it is not enough for a plaintiff merely to impugn
    the veracity of the employer's justification; [s]he must elucidate
    specific facts which would enable a jury to find that the reason
    given is not only a sham, but a sham intended to cover up the
    employer's real and unlawful motive of discrimination." (internal
    quotation marks and brackets omitted)).
    Here,   as   his   proffered    evidence    of   pretext,   Brader
    points to perceived inconsistencies between Biogen's reasons for
    terminating him and its actions after he was laid off, such as the
    record evidence indicating that Biogen continued to develop his
    novel crystallization concept after he was terminated and that,
    three months after Brader's departure, Biogen posted two positions
    for an engineer and post-doctoral student with crystallization
    experience.      In addition, Brader argues the innovation work that
    purportedly landed Brader on Galdes' termination list made up only
    15%   of   his   job.    Brader   says     in   light   of   these   perceived
    inconsistencies, Biogen's actions are evidence of pretext, and the
    undisputed material facts cast doubt on the veracity of Biogen's
    reasoning for terminating him.
    Biogen says Brader's pretext argument amounts to nothing
    more than subjective speculation unsupported by the evidence and
    can be reduced to Brader's disagreement with Biogen's business
    rationale for including Brader on the Gemstone list.
    - 31 -
    Even viewing the record in the light most favorable to
    Brader, we conclude it is clear that he has not tendered sufficient
    evidence   from   which   a   reasonable   jury   could   infer   that
    discriminatory animus was a motivating factor in his termination
    as part of Biogen's reduction-in-force.
    Much of Brader's argument takes aim at the fact that
    Biogen advertised two crystallization-experience-required jobs in
    the wake of his departure -- according to Brader, that shows Biogen
    still needed Brader's skills.    But this take is flawed.     For one
    thing, even if Biogen determined there was no business case for
    Brader's role on the crystallization project and other innovation-
    related projects, Biogen's decision to reallocate resources to
    such projects after Brader's termination, without more, does not
    raise a reasonable inference of discriminatory animus.     See, e.g.,
    Lewis v. City of Boston, 
    321 F.3d 207
    , 216 (1st Cir. 2003) ("Merely
    demonstrating that, as a result of the reduction in force, the
    employer consolidated positions or allocated duties of discharged
    employees to other existing employees does not itself raise a
    reasonable inference that the employer harbored discriminatory
    animus toward any one employee.").         Indeed, Biogen not only
    underwent a reduction-in-force, but also it undertook an entire
    rethinking of its business strategy.       Plus, we note that Brader
    was not singled out for inclusion on the Gemstone list, but rather
    his post-doctoral student also was terminated as part of Biogen's
    - 32 -
    reduction-in-force and new take on business strategy and company
    priorities.    Where, as here, courts are "faced with employment
    decisions that lack a clear discriminatory motive," we "'may not
    sit as super personnel departments, assessing the merits -- or
    even the rationality -- of employers' nondiscriminatory business
    decisions.'"   Rodríguez-Cardi v. MMM Holdings, Inc., 
    936 F.3d 40
    ,
    48-49 (1st Cir. 2019) (quoting Mesnick v. Gen. Elec. Co., 
    950 F.3d 816
    , 826 (1st Cir. 1991)).     "We are left, then, with the sort of
    'criticisms of [an employer's] decision making process' attendant
    to a reduction-in-force that 'fail to reveal any hidden animus
    . . . .'"   Dunn v. Trs. of Boston Univ., 
    761 F.3d 63
    , 74 (1st Cir.
    2014) (alteration in original) (quoting Sullivan v. Liberty Mut.
    Ins. Co., 
    825 N.E.2d 522
    , 542 (Mass. 2005)).
    What's more, Galdes testified that the positions posted
    (a senior manufacturing engineer, not a research scientist; and a
    temporary co-op student) after his departure were not similar to
    Brader's position.    In fact, there is no evidence that the post-
    reduction-in-force hiring was geared towards the same type of
    crystallization work Brader had pursued.       And furthermore, Galdes
    explained, Brader was not qualified for the posted senior engineer
    position since, to the best of Galdes' knowledge, Brader is not an
    engineer and has no experience "milling small molecules" (as was
    required for the senior engineer position).         Our review of the
    record   reveals   Brader   provided   no   independent,   contradictory
    - 33 -
    evidence from which a jury could reasonably surmise otherwise,
    i.e., that Biogen's posted positions for a senior engineer and a
    post-doctoral student were substantially similar to the position
    Brader held and that he was qualified to fill these positions.             To
    the extent Brader points to his own declarations of qualifications,
    he fails to explain why that would be so.
    As to Brader's proposition that his innovation work
    constituted only 15% of his job (so using that part of his job to
    justify his termination must have been pretextual), this argument
    is at odds with the record evidence.           Galdes testified that he
    never saw the 2015 mid-year evaluation breaking down Brader's self-
    described work percentages, and thus he did not take it into
    consideration when he concluded Brader would be on the Gemstone
    list.     Again, Brader points to no evidence which contradicts
    Galdes' assertions.        And to the extent that Brader believes
    spending only 15% of his time on this innovative work (as opposed
    to another Biogen employee devoting 20% of his or her time to the
    same work) demonstrates a sham justification, this, too, fails to
    move the evidentiary needle -- all it shows, at most, is that
    Biogen shuffled allocation of duties amidst the restructuring, and
    that on its own cannot give rise to an inference of discriminatory
    animus or pretext.     See Lewis, 
    321 F.3d at 216
    .
    With respect to Brader's insistence that Galdes not only
    knew    about   Brader's   disability,   but   also   clearly   harbored    a
    - 34 -
    disability-based discriminatory animus that drove him to include
    Brader on the Gemstone list, yet again, Brader simply hasn't done
    the evidentiary legwork to show that Galdes considered Brader to
    be disabled such that a jury could infer Galdes' discriminatory
    animus prompted him to terminate Brader.         Yes, Galdes was Cc'd on
    some of the emails Brader sent during his mental break, so Galdes
    was   generally   aware   of   the   mental    health   incident   Brader
    experienced in June 2014.      But from there, the evidence shows that
    Brader's wife explained to Sinclair that Brader's mental health
    incident was only a temporary one -- a message she passed along to
    Galdes in July 2014 -- and there is nothing in the record to show
    Galdes believed it was not temporary.           Plus, Brader never held
    himself out as disabled upon his return to work, nor did he make
    any mention of an ongoing disability or request accommodation for
    a disability.     So there is no evidence that Galdes considered
    Brader to be disabled, rather than believing the mental health
    issue was temporary, and Galdes, as the appellate record supports,
    didn't take that temporary mental health issue into account when
    he made his termination decision.          Furthermore, Galdes testified
    that he consulted with neither Weiskopf nor Ballinger (recall
    operation Gemstone was the well-kept secret of twenty Biogen
    employees worldwide) regarding his decision to terminate Brader
    (such that he might have learned about any potential ongoing
    disability issues that way), and there's no evidence to suggest
    - 35 -
    otherwise.    Remember:       as sole decisionmaker, Galdes is our focus.
    See, e.g., Vélez, 
    585 F.3d at 452
     (emphasizing that a reviewing
    court's focus is on the decisionmaker's perception, i.e., whether
    that decisionmaker thought the stated reason for a given employment
    action was a credible one).            There's simply nothing to go on here
    that would allow a factfinder to infer discriminatory animus as
    driving Galdes' decision-making.
    In the end, Brader's arguments simply fail.             Of course
    he's not wrong that it is a "factfinder's job to . . . weigh the
    evidence," but it is axiomatic that his case would not reach a
    jury unless he first showed "some minimally sufficient evidence"
    of pretext and a discriminatory animus, and trying to raise a
    triable issue on the topic of pretext cannot be accomplished by
    advancing    "[m]ere     questions"       focusing   on   Biogen's   "business
    judgment."    Pearson, 723 F.3d at 40 (quoting Acevedo-Parrilla, 696
    F.3d   at   140).      Brader    cannot    just   "impugn   the   veracity   of
    [Biogen]'s justification" -- he needed to point us to "'specific
    facts which would enable a jury to find that the reason given is
    not only a sham, but a sham intended to cover up [Biogen]'s real
    [and unlawful] motive' of discrimination."            Azimi, 
    456 F.3d at 246
    (third alteration in original) (quoting Mesnick, 950 F.2d at 824);
    see also Vélez, 
    585 F.3d at 452
    .
    Brader     has      not      successfully      navigated    these
    fundamentals.       Rather, Brader's efforts to demonstrate pretext can
    - 36 -
    be reduced to subjective disagreements with Biogen's business
    judgment relative to its reduction-in-force decisions.        Without a
    supportable discriminatory motive in the record, as we wrote
    earlier, we "may not sit as super personnel departments, assessing
    the   merits   --   or   even   the   rationality   --   of   employers'
    nondiscriminatory business decisions."      Rodríguez-Cardi, 936 F.3d
    at 48-49 (quoting Mesnick, 950 F.2d at 825).        Brader has given us
    only "the sort of 'criticisms of [an employer's] decision making
    process' attendant to a reduction-in-force that 'fail to reveal
    any hidden animus.'"     Dunn, 761 F.3d at 74 (quoting Sullivan, 825
    N.E.2d at 542).     Overall, since Brader did not proffer evidence
    from which a reasonable jury could infer that Galdes (and, by
    extension, Biogen) harbored discriminatory animus against him, he
    has not satisfied his burden of production as to pretext under the
    McDonnell Douglas framework.
    Meanwhile, Brader's Chapter 151B claims are also subject
    to the McDonnell Douglas burden-shifting framework, Ray, 799 F.3d
    at 113 n.8, with one applicable distinction; "Massachusetts is a
    pretext only jurisdiction," Bulwer v. Mount Auburn Hosp., 
    46 N.E.3d 24
    , 33 (Mass. 2016) (quoting Blare v. Husky Injection Molding Sys.
    Boston, Inc., 
    646 N.E.2d 111
    , 116 (Mass. 1995)), so a plaintiff,
    to survive summary judgment, "need only present evidence from which
    a reasonable jury could infer that 'the [employer's] facially
    proper reasons given for its action against him were not the real
    - 37 -
    reasons for that action,'" 
    id.
     (quoting Wheelock Coll. v. Mass.
    Comm'n Against Discrimination, 
    355 N.E.2d 309
    , 315 (Mass. 1976)).23
    For the reasons just explained, Brader's proffered evidence of
    pretext does not satisfy this burden.
    B.   Brader's Disability Harassment Claim:
    A Hostile Work Environment
    That leaves Brader's other disability discrimination
    claim -- he was harassed based on his disability in violation of
    the ADA and Chapter 151B by virtue of the hostile work environment
    he was forced to endure, and which led to and included his eventual
    termination.      As we'll explain shortly, Brader points in part to
    some untimely conduct to support this claim.                   And so, in the
    analysis that follows, we assess the interplay between his efforts
    to sidestep statute-of-limitations issues and his hostile work
    environment claim.      See Morgan, 536 U.S. at 120 ("[A] court's task
    is to determine whether the acts about which an employee complains
    are part of the same actionable hostile work environment practice,
    and   if   so,   whether   any   act    falls   within   the   statutory   time
    period.").
    We have said that a plaintiff may demonstrate an ADA
    violation by establishing that an employer required him or her to
    23  In other words, Massachusetts law differs from federal
    law in that plaintiffs do not need to establish both discriminatory
    animus and pretext; they just need to show pretext. See Bulwer,
    46 N.E.3d at 33.
    - 38 -
    work in a hostile or abusive environment on account of their
    disability.    See Murray, 821 F.3d at 86 and n.1 (collecting cases
    and     generally    recognizing        disability-based        hostile   work
    environment claims under the ADA).            To successfully make out this
    hostile work environment claim, "a plaintiff must show harassment
    'sufficiently severe or pervasive so as to alter the conditions of
    [his]   employment    and     create    an    abusive    work   environment.'"
    Maldonado-Cátala, 876 F.3d at 10 (quoting Pérez-Cordero v. Wal-
    Mart P.R., Inc., 
    656 F.3d 19
    , 27 (1st Cir. 2011)). "The challenged
    conduct must be 'both objectively and subjectively offensive, such
    that a reasonable person would find it hostile or abusive and the
    plaintiff in fact did perceive it to be so.'"             
    Id.
     (quoting Pérez-
    Cordero, 
    656 F.3d at 27
    ).        We are mindful that we "must mull the
    totality of the circumstances, including factors such as the
    'frequency of the discriminatory conduct; its severity; whether it
    is physically threatening or humiliating, or a mere offensive
    utterance;    and   whether    it    unreasonably       interfere[d]   with   an
    employee's work performance.'"         
    Id.
     (quoting Noviello, 
    398 F.3d at 92
    ); see also Faragher v. City of Boca Raton,

    235 F.3d 713
    , 729 (1st
    Cir. 2001).
    Critically, "[t]he harassment also must stem from an
    impermissible motivation."          Maldonado-Cátala, 876 F.3d at 10; see
    also id. at 10 n.11 (citing Ponte v. Steelcase Inc., 
    741 F.3d 310
    ,
    - 39 -
    320 (1st Cir. 2014)); Murray, 821 F.3d at 86; Quiles-Quiles v.
    Henderson, 
    439 F.3d 1
    , 7-8 (1st Cir. 2006) (explaining that "an
    employee claiming harassment must demonstrate that the hostile
    conduct was directed at him because of a characteristic protected
    by a federal anti-discrimination statute"). We remind, a plaintiff
    like Brader "bears the burden of presenting evidence to establish
    each element under the particular theory" alleged under the ADA.
    Murray, 821 F.3d at 83. And our role in all of this is to determine
    if the plaintiff has put forth sufficient evidence "to distinguish
    between the ordinary, if occasionally unpleasant, vicissitudes of
    the workplace and actual harassment."     Noviello, 
    398 F.3d at 92
    .
    In Massachusetts, the continuing violation doctrine can
    apply to Chapter 151B claims if a plaintiff establishes that "at
    least   one   discriminatory   act   occurred"   within   the   300-day
    limitations period; the alleged discriminatory act must have a
    "substantial relationship to the alleged untimely discriminatory
    acts"; and the earlier violations were such that they "did not
    trigger [the plaintiff's] awareness and duty to assert his rights."
    Ocean Spray Cranberries, Inc., 808 N.E.2d at 266-67.
    The general principles laid out, we now turn to a
    critical procedural stumbling block which impedes Brader's claims
    -- the statute of limitations -- since whether and how Brader
    surmounts this obstacle dictates our analysis of his hostile work
    - 40 -
    environment claim.24           Both the ADA and Chapter 151B instruct that
    plaintiffs (like Brader) may "maintain a civil action only if
    [they]    have    filed    a    timely     complaint      with     the   Massachusetts
    Commission Against Discrimination."                    Christo v. Edward G. Boyle
    Ins. Agency, Inc., 
    525 N.E.2d 643
    , 644 (Mass. 1988) (citing Mass.
    Gen. Laws ch. 151B, § 9).                Chapter 151B requires that an MCAD
    complaint    be    filed       within    300    days    of   the   alleged   unlawful
    employment practice.            See Mass. Gen. Laws ch. 151B, § 5.              Here,
    the 300-day limitations period applies to Brader's federal and
    state-law discrimination claims.               Brader doesn't dispute this, nor
    does he contest the district court's conclusion that the alleged
    discriminatory      acts       committed       by   Biogen   in    2014,    viewed   in
    isolation, are time-barred.              With that, he concedes that certain
    of the alleged adverse actions (failure to promote, removal from
    the Avia project, Weiskopf's 2014 criticism, and HR's failure to
    investigate) are not actionable on their own under the ADA or
    Chapter 151B.       See Morgan, 536 U.S. at 109 (explaining that any

    In trying to persuade us the statute of limitations does
    not slam the door on certain claims, Brader directs us to the
    continuing violation doctrine, which provides that "a plaintiff
    may obtain recovery for discriminatory acts that otherwise would
    be   time-barred    so   long    as    a     related   act   [(often   called     an
    'anchoring act')] fell within the limitations period."                 Maldonado-

    553 F.3d 121

    R.C., Inc. v. SCA Tissue N. Am., LLC, 
    794 F.3d 200
    , 205 (1st Cir.
    2015) (observing that, "[a]s long as a related act falls within
    the limitations period, the doctrine allows a lawsuit to be delayed
    in cases -- such as hostile work environment claims -- in which a
    course of 'repeated conduct' is necessary before 'a series of
    wrongful   acts    blossoms     into    an    injury   on    which   suit   can   be
    - 42 -
    brought'" (quoting Ayala v. Shinseki, 
    780 F.3d 52
    , 57 (1st Cir.

    398 F.3d at 86
     (observing that the
    related "anchoring act" must "substantially relate[] to earlier
    [untimely] incidents of abuse").        So a litigant who wants the
    continuing violation doctrine to apply to untimely conduct must
    establish a timely and related anchoring act to which the untimely
    conduct can be tethered.
    We've described hostile work environment claims "as the
    classic example of a continuing violation," Maldonado- Cátala, 876
    F.3d at 9, since they "cannot be said to occur on any particular
    day" because "the actionable wrong is the environment, not the
    individual acts that, taken together, create the environment,"

    553 F.3d at 130

    hostile work environment encompasses a single unlawful employment
    practice").   "[A]ll of the 'component acts' alleged in a hostile
    work environment claim may be considered in determining liability
    even if they occurred outside the limitations period."   Maldonado-
    Cátala, 876 F.3d at 9.     In truth, this equitable doctrine is not
    really "about a continuing [violation], but about a cumulative
    violation."   Quality Cleaning, 794 F.3d at 205 (emphases added)
    (quoting Limestone Dev. Corp. v. Vill. of Lemont, Ill., 520 F.3d
    - 43 -
    797, 801 (7th Cir. 2008) (Posner, J.)).25
    Here's   the   bird's-eye   view   of   how    these   principles
    converge for our analytical purposes: most of Brader's complained-
    of conduct will be "off limits unless [he] can surmount the time-
    bar for actions that occurred" in 2014 since, as we just explained,
    we can consider Biogen's alleged 2014 behavior "only if at least
    one of the incidents that occurred" during the limitations period
    (an anchoring act) "constitutes part of the same hostile work
    environment as the alleged wrongful conduct that preceded that
    date."       Maldonado-Cátala, 876 F.3d at 10.
    Brader points to a pattern of adverse employment actions
    by Biogen, or, as he calls it, the "pinprick after pinprick" that
    added        up    to   the   "cumulative     effect"     of    "intolerable   work
    conditions":            Biogen's failure to promote him, its decision to
    remove him from the Avia project,26 its failure to investigate his
    safety and harassment complaints in violation of internal policy,
    25Indeed, the idea of it being a "continuing violation" is
    quite the misnomer since "unlawful discrimination . . . is often
    a cumulative process rather than a one-time event discrimination"
    -- "[t]he first instance of . . . offensive words or actions may
    be too trivial to count as actionable harassment, but if they
    continue they may eventually reach that level and then the entire
    series is actionable." Limestone, 520 F.3d at 801 (citing Morgan,
    536 U.S. at 117).
    26In his brief, Brader acknowledges that as a practical
    matter, the reassignment of the Avia project was a reasonable move
    given Brader's absence. But ultimately, he views his removal as
    part of a grander Biogen scheme to get rid of him because of his
    disability.
    - 44 -
    Weiskopf's ongoing harassment, and his eventual termination in
    2015.    To Brader's thinking, a jury could reasonably view Biogen's
    "hostile,"     discriminatory       conduct   as   part   of    a     "linked,"
    "prolonged and compelling pattern of mistreatment" constituting
    one employment practice, all of which was substantially related to
    his   discrimination-fueled     termination.       Indeed,     all    of   these
    component acts, says Brader, added up to a hostile work environment
    that culminated in his wrongful discharge.
    Here, to support his hostile work environment claim,
    Brader    complains   about   two    categories    of   timely,      anchoring,
    abusive conduct driven by disability-based discriminatory animus
    towards him:    (1) Weiskopf's criticisms and alleged harassment in
    2015; and (2) Brader's November 2015 termination.            But our careful
    review of the record tells us that this conduct lacks evidentiary
    support that would permit a jury to conclude either that the
    alleged anchoring acts are substantially related to the prior
    incidents Brader complains of (i.e., that the conduct was part of
    a pattern), Noviello, 
    398 F.3d at 86
    , or that it constituted
    "'severe or pervasive' harassment that 'alter[ed] the conditions
    of his employment and create[d] an abusive work environment'
    extending into the relevant time period," Maldonado-Cátala, 876
    F.3d at 11 (quoting     Pérez-Cordero, 
    656 F.3d at 27
    ), or that the
    alleged anchoring-act harassment "stem[med] from an impermissible
    motivation," id. at 10, i.e., that Brader was subjected to this
    - 45 -
    "hostile conduct" because of his disability, Quiles-Quiles, 
    439 F.3d at 7-8
    .
    Take Brader's claims regarding Weiskopf and the role he
    is alleged to have played in creating the hostile work environment
    Brader alleges. The timely 2015 Weiskopf conduct at issue involves
    (1) Weiskopf's criticism of Brader's crystallization project and
    (2) his overseeing of Brader's mid-year review.              The evidence
    Brader relies on to support his harassment claim on this front
    comes   from     his   deposition     testimony    regarding    his    2015
    interactions with Weiskopf.       Brader testified that Weiskopf had a
    disingenuous     response   to    Brader's   crystallization     proposal,
    rebuked him for asking too many questions in meetings, and failed
    to set clear expectations for Brader in advance of the 2015 mid-
    year review.
    For    starters,      Brader's    generic   complaints     about
    Weiskopf's criticisms and his effectiveness as a supervisor do not
    rise to the level of "sufficiently severe or pervasive so as to
    alter the conditions of [his] employment."         Maldonado-Cátala, 876
    F.3d at 10 (quoting     Pérez-Cordero, 
    656 F.3d at 27
    ).        While we do
    not doubt Brader felt harassed, even as we look to the "totality
    of the circumstances," Brader offers no evidence as to how,
    exactly,   any    of   Weiskopf's     behavior    actually     constituted
    harassment in that it impacted his working conditions in such a
    way that could be reasonably viewed by a jury as being carried out
    - 46 -
    in a severe or pervasive fashion.         See 
    id.
       For example, consider
    Weiskopf's criticism of Brader's crystallization project, which
    Brader says Weiskopf lacked the expertise to judge.            Importantly,
    Brader, at the time the criticism was leveled, pegged Weiskopf's
    negative critique not on disability animus but on professional
    jealousy or Weiskopf's desire to take undue credit for Brader's
    work.    But even Weiskopf's criticism was tempered with praise; he
    acknowledged Brader's concept as innovative.              Brader fails to
    explain   why   Weiskopf    taking   issue   with   Brader's    methods    of
    soliciting support for his new project or his request that Brader
    not share the concept outside of PPD until Weiskopf and Brader
    discussed it one-on-one could be reasonably viewed as harassment.
    Same goes for Weiskopf's purported admonitions to Brader for asking
    too many questions in meetings and generally "trying too hard."
    Brader has not shown how Weiskopf's conduct here falls outside the
    boundaries of valid, supervisory critique.              Plus, in the end,
    Brader    got   what   he   wanted   --    permission    to    present    his
    crystallization project.       So, to repeat, it is entirely unclear
    how this episode of Weiskopf criticism, alone or in conjunction
    with the other events complained of, could objectively constitute
    harassment or how it impacted Brader's work conditions.
    The same is true of Weiskopf and the 2015 performance
    review installment in this saga.             Brader was upset that his
    performance review included some unfavorable feedback (recall that
    - 47 -
    some     peers   and      stakeholders    had   described      Brader       being
    "dismissive" and "confrontational" in response to suggestions and
    feedback he received in group meetings).             But again, Brader hasn't
    shown us how this amounted to harassment rather than Weiskopf
    simply doing his job:           Brader even seemed to acknowledge as much
    when, in a meeting he requested to complain about Weiskopf's
    treatment of him, he told Ballinger he did "not question[] the
    veracity    of   [Weiskopf's]      feedback,"   he    just   took   issue    with
    Weiskopf's "consistency in communicating and administering clear
    goals and expectations with metrics of success associated with
    them."    At no point did Brader express concerns about harassment.
    So once again, this conduct, alone or in conjunction with other
    conduct,    does    not     reasonably    amount      to   harassing    conduct
    "sufficiently severe or pervasive so as to alter the conditions of
    [his] employment."        
    Id.
    We similarly fail to see any evidence showing that this
    conduct is not only subjectively offensive (as Brader says it was),
    but also objectively so, "such that a reasonable person would find
    it hostile or abusive."           
    Id.
     (quoting Pérez-Cordero, 
    656 F.3d at 27
    ).     In fact, yet again, there's no evidence that Weiskopf's
    alleged harassment of Brader amounted to anything other than
    Weiskopf levying criticisms and voicing concerns as he performed
    his duties as a supervisor; rather, at most, these are "minor
    instances of employment skirmishes" that "cannot ground [Brader]'s
    - 48 -
    hostile work environment claims."             Murray, 821 F. 3d at 87; see
    also Colón-Fontánez v. Municipality of San Juan, 660 F.3d at 17,
    44-45 (1st Cir. 2011) (finding no hostile work environment when
    complained-of interactions were "brusque and even uncivil," but
    incidents were episodic rather than frequent, and upsetting but
    not severe).
    All    told,   Brader    simply     hasn't    adduced    sufficient
    evidence to show that Weiskopf's supervisory behavior amounted to
    anything other than that:        a supervisor doing the "appropriate and
    necessary duties of [his] job[]."         Murray, 821 F. 3d at 87.
    And if all that wasn't enough, Brader has fallen short
    on a different but critical aspect of what he needed to show to
    square this so-called Weiskopf "harassment" away as anchoring
    conduct:     "the    [alleged]      harassment   also     must   stem   from    an
    impermissible motivation."        Maldonado-Cátala, 876 F.3d at 10.            But
    Brader does not connect any evidentiary dots as to how Weiskopf's
    conduct    tends   to   show   Weiskopf   harbored       any   disability-based
    discriminatory animus whatsoever towards Brader.                 For instance,
    Brader does not direct us to competent record evidence of the kind
    we sometimes see in other employment discrimination claims of
    Weiskopf hurling disability-based invectives at Brader, see, e.g.,
    Murray, 821 F.3d at 87 (pointing to evidence of a variety of snide
    comments, such as "a younger person could do the task very easily,"
    in an effort to support disability harassment claim); Quiles-
    - 49 -
    Quiles, 
    439 F.3d at 4
     (proffering evidence that, among other
    things, supervisors called the appellant "'crazy' on a daily basis"
    and   "'joked'   .    .   .   about     the    fact    that    [appellant]   saw    a
    psychiatrist and took medication for his condition"), nor does he
    argue that Weiskopf is guilty of such ubiquitous, disability-
    driven attacks in support of his harassment claim.
    As for Weiskopf's management style to which Brader took
    offense, keep in mind, as Brader tells it, Weiskopf was ill-
    tempered towards Brader before he showed any signs of a mental
    disability:   recall Weiskopf's harsh critique of Brader's June 18,
    2014 PPD presentation to senior management predated any evidence
    of manifestations of Brader's mental health issue.                         We have
    consistently acknowledged in similar employment dispute cases that
    "[t]oiling under a boss who is tough, insensitive, unfair, or
    unreasonable can be burdensome," but even to the extent Weiskopf
    fit this bill, Brader hasn't shown that he behaved that way due to
    discriminatory animus -- and "generally disagreeable behavior and
    discriminatory       animus      are   two    different     things."      Ahern    v.
    Shinseki, 
    629 F.3d 49
    , 59 (1st Cir. 2010); see also Noviello, 
    398 F.3d at 92
     (emphasizing our court's role in distinguishing "between
    the ordinary, if occasionally unpleasant, vicissitudes of the
    workplace and actual harassment").
    So,   in       sum,     Brader     has     not     proffered   minimally
    sufficient evidence from which a jury could infer that his alleged
    - 50 -
    harassment by Weiskopf was so severe or pervasive that it altered
    his work conditions and fostered an abusive environment in the
    limitations period, nor did he adduce evidence showing that the
    harassment owed to an impermissible motivation.        Murray, 821 F.3d
    at 83, 86; Maldonado-Cátala, 876 F.3d at 10.         These showings not
    made, the conduct cannot anchor the untimely conduct Brader wants
    us to consider under the continuing violation doctrine as part of
    his hostile work environment claim.
    That sorted, we turn to the remaining limitations period
    conduct that Brader wants to deem the anchoring hostile work
    environment conduct such that he can use the continuing violation
    doctrine to sweep the untimely acts up into his claim:                  his
    November 2015 termination.
    We know from our earlier wrongful termination discussion
    that Biogen articulated what we concluded were legitimate, non-
    discriminatory reasons for including Brader in the reduction-in-
    force.   In the hostile work environment claim, though, Brader says
    his termination takes on a different role as the final (timely)
    act of harassment that is "substantially related" to all the other
    component   acts   of   his   hostile   work   environment   (failure    to
    investigate, Weiskopf's 2014 harassment, and so on).
    Remember Brader's burden here:         we can consider the
    - 51 -
    untimely misbehavior by Biogen only if the termination,27 as the
    anchoring   act,   is   indeed   substantially    related    to   the   other
    conduct, "constitut[ing] part of the same hostile work environment
    as the alleged wrongful conduct that preceded" it, and if it
    "stem[med] from an impermissible motivation," Maldonado-Cátala,
    876 F.3d at 10, i.e., the "conduct [(his termination)] was directed
    at him because of" his disability, Quiles-Quiles, 
    439 F.3d at
    7-
    8.
    Putting aside the requirement that the termination must
    be shown to be part of the same pattern constituting a hostile
    work environment as the 2014 instances of misconduct by Biogen
    (and we're not convinced Brader has shown any of those instances
    to be at all related either to his termination or shown any of
    those instances to be related to one another), our earlier wrongful
    discharge analysis dispensed with Brader's position that he has
    offered   sufficient    evidence   to   show   that   his   termination   (a
    decision made by an independent actor without consulting others,
    remember) owed to and "stem[med] from" the disability-related
    discriminatory animus he says it did.          Maldonado-Cátala, 876 F.3d
    at 10; Quiles-Quiles, 
    439 F.3d at 7-8
    .          As such, the termination
    cannot serve as an anchoring act for the untimely conduct, meaning
    the continuing violation doctrine is not in play here either, and
    27   No one disputes that Brader's termination altered the
    conditions of his employment.
    - 52 -
    we cannot consider the untimely conduct.            We need say no more.
    In   winding   down   our    analysis,    we    stress     that     our
    jurisprudence    identifies    that     "'[t]he   accumulated         effect'    of
    behaviors    that   individually    fall    short    may,     taken    together,
    constitute a hostile work environment."               Maldonado-Cátala, 876
    F.3d at 12 (quoting O'Rourke, 
    235 F.3d at 729
    ).             But to sway us on
    this "accumulated effect" phenomenon, Brader needed to show not
    only that the timely behavior contributed to a hostile work
    environment, but also that the timely harassment was driven by
    some      impermissible     motivation       (here,        disability-related
    discriminatory animus).       See, e.g., id. at 10.             Brader hasn't
    proffered sufficient evidence to permit a finding that any of this
    timely conduct was part of a hostile work environment stemming
    from   disability-related     discriminatory        animus.      And     indeed,
    because    Brader   (the   nonmoving     party)   carries      the    burden     of
    persuasion on his claims, he needed to martial "'specific facts,
    in suitable evidentiary form,' sufficient to limn a trialworthy
    issue."     Lawton v. State Mut. Life Assur. Co. of Am., 
    101 F.3d 218
    , 223 (1st Cir. 1996) (quoting Morris v. Govt. Dev. Bank, 
    27 F.3d 746
    , 748 (1st Cir. 1994)).            Failure to do so "allows the
    summary judgment engine to operate at full throttle."                   
    Id.
         The
    intended goal of summary judgment "is to pierce the boilerplate of
    the pleadings and assay the parties' proof in order to determine
    whether trial is actually required."         Id. at 222 (quoting Wynne v.
    - 53 -
    Tufts Univ. Sch. of Med., 
    976 F.2d 791
    , 794 (1st Cir. 1992)).             So
    it is here:     Brader has not met his burden to produce competent
    evidence showing that the timely 2015 work conditions he faced
    amounted to harassment on the basis of the improper motivations he
    alleges.   Id. at 223.
    IV. WRAP UP
    That,   as   they   say,   is   that.     The   district   court
    appropriately concluded that Brader had not produced sufficient
    evidence to survive summary judgment on his claims.            We affirm its
    grant of summary judgment against Brader.            Each side will bear its
    own costs.
