    KAFKER, J.     The issue presented is whether the Civil
    Service Commission (commission) can consider evidence related to
    a racially hostile or retaliatory work environment when
    assessing whether a municipality had just cause to terminate a
    tenured civil service employee.     The underlying dispute in this
    case began with a racist comment, apparently on a misplaced
    telephone call.    As Lieutenant Paul Pender was in a car driven
    by his son, he was cut off by a stranger.     Pender referred to
    the person as a "fucking n----r."     Unbeknownst to him, Pender
    had not properly hung up from a previous call, and he left a
    record of what he said on the voicemail of fellow firefighter
    Gerald Alston.    Alston is African-American; Pender, his
    supervisor at the time, is Caucasian.     A tumultuous six years of
    litigation and acrimony ensued, culminating in 2016 with Pender
    receiving his third promotion since leaving the voicemail and
    Alston being fired by the town of Brookline (town).     When Alston
    challenged his termination before the commission, the commission
    first summarily concluded that the town had just cause to
    terminate Alston due to his extended absence from duty and his
    failure to cooperate with the town's return to work
    requirements.    Alston successfully challenged that ruling in the
    3
    Superior Court, and the matter was remanded to the commission
    for an evidentiary hearing.   After that hearing on remand, the
    commission concluded that there was not just cause for the
    discharge, as the decision to terminate Alston was "arbitrary,
    capricious, and in violation of [his] rights under the civil
    service law to be treated fairly 'without regard to . . . [his]
    race.'"   The commission ordered his reinstatement, and that
    decision was affirmed by the same Superior Court judge.     The
    town appealed, and we transferred the matter to this court on
    our own motion.
    We first conclude that the commission can consider, in the
    context of its analysis whether an employee was fired without
    just cause in violation of basic merit principles, evidence of
    discriminatory or retaliatory conduct that is more typically
    addressed in the context of a claim under G. L. c. 151B.     The
    relevant statutes ensure that civil service employees are not
    terminated without just cause and that their termination be
    consistent with basic merit principles.   A civil service
    employee whose unfitness is determined to be caused by racist
    remarks and retaliation in the workplace and the employer's
    arbitrary and capricious response to such remarks and
    retaliation may not be terminated by the employer responsible
    for causing the unfitness.    Applying this standard, we conclude
    that the commission's determination that the town lacked just
    4
    cause to discharge Alston is supported by substantial evidence.
    Finally, as described more fully infra, we reject each of the
    town's arguments as to why the commission exceeded its authority
    and lacked substantial evidence for its decision.2
    1.   Commission's findings.   We present the relevant facts
    as found by the commission.     As this case involves events that
    occurred over the course of six years, and because its
    disposition depends on the unusual, if not unique, facts found
    here, we provide a detailed factual and procedural background.
    a.   Voicemail incident.   Alston became a firefighter with
    the town in 2002.   He served on a full-time basis for eleven
    years.    He was considered a "very good firefighter."     In 2010,
    he was assigned to Group 2, Station 5.    Pender, then a
    lieutenant, was one of Alston's supervisors in Group 2.      Pender
    joined the town's fire department (department) in 1984.      Prior
    to May 2010, Pender and Alston had a good relationship.      Alston
    described Pender as someone he "attached to when [Alston] got on
    the job because [Pender] knew, as far as [Alston] could tell,
    everything about the station, everything about firefighting . .
    2 We acknowledge the amicus brief submitted by Brookline for
    Racial Justice and Equity, Raul Fernandez, and Brookline Budget
    Justice, as well as the amicus brief submitted by the
    Massachusetts Employment Lawyers Association and Lawyers for
    Civil Rights.
    5
    . .   [Alston] would ask certain questions and [Pender] always
    had the answer."
    Early in 2010, Alston suffered an injury while on duty that
    kept him out of work.   On May 30, 2010, Pender called Alston to
    check on his well-being, but the call went to Alston's
    voicemail.   Pender thought that he had ended the call but in
    fact had not.   As a result, Pender left the voicemail on
    Alston's telephone in which he said "fucking n----r."3     Alston's
    wife listened to the voicemail first and then told Alston to
    listen to it.   Alston was shocked and hurt by the slur.    Unsure
    whether the voicemail included the slur, Pender called Alston
    numerous times that same day and in the ensuing days; Alston
    never returned his calls.   Pender testified that he also told
    other firefighters what happened and "sort of expressed relief
    [to them] that . . . [Alston] was [his] buddy and [he was] sure
    nothing was going to happen."
    Alston sought advice from several senior firefighters on
    what he should do about the incident.   He also spoke with the
    chief of operations, Michael O'Reilly, shortly after May 30 and
    played the voicemail for him.   O'Reilly did not report the
    3At the time he used the racial slur, Pender was in a car
    with his son driving. The commission credited Pender's
    testimony that Pender used the slur to refer to another driver,
    not Alston. Pender has described the driver at whom he directed
    the slur on various occasions as "a young black kid," a "black
    or Hispanic" male, and "some young gangbanger."
    6
    incident to the fire chief or town officials.     O'Reilly and
    Alston agreed that Alston would reach out to Pender directly.
    Pender and Alston spoke by telephone on July 8, and Pender told
    Alston that the slur was not intended for him but was directed
    at "some young gangbanger" who had cut him off in traffic.       This
    further upset Alston, who ended the call.    Pender called Alston
    again two days later and repeated his explanation of the context
    in which he made the slur.   He also told Alston that reporting
    the incident to O'Reilly was the most stupid thing Alston could
    have done and asked Alston, "Do you want me to lose my job?"
    On July 28, Alston sent a formal complaint to the then fire
    chief, Peter Skerry.   Skerry immediately notified the town's
    director of human resources, Sandra DeBow.   Two days later, on
    July 30, Alston, his wife, Skerry, O'Reilly, and town counsel
    met to address the complaint.   Alston played the voicemail at
    the meeting.   After hearing the message, Skerry determined that
    Pender's use of the slur was a fireable offense and told Alston
    that he would fight for Pender's termination.     Alston responded
    that he did not want Pender terminated.   Skerry also told Alston
    that Pender would be ineligible for a promotion and assured
    Alston that the department took his complaint seriously.     That
    day, Pender was transferred to another station.
    7
    DeBow began an investigation into the incident.4    As part of
    her investigation, she interviewed Pender on August 2.     During
    that interview, Pender admitted using the slur but maintained
    that it was not directed at Alston.    On August 16, DeBow issued
    her investigative report, which concluded that Pender's use,
    during a work-related call, of "profanity and a well-recognized,
    racially-inflammatory term rises to the level of conduct
    unbecoming to a firefighter as it would tend to lower the
    service in the estimation of the [p]ublic, and further that such
    conduct is also prejudicial to good order."    DeBow recommended
    progressive discipline, Pender's permanent transfer, mediation
    between Alston and Pender, development of an antidiscrimination
    policy, and antidiscrimination training, including training on
    supervisors having a duty to report incidents.
    On August 17, the day after DeBow issued her report, the
    town's board of selectmen (board) held a closed-door
    disciplinary hearing for Pender.    Alston was not called as a
    witness and did not appear before the board.     Skerry recommended
    that Pender be suspended for four tours (the equivalent of
    eighty-four hours of lost pay).    The board rejected Skerry's
    recommendation and chose to suspend Pender for two tours with
    4 Alston wanted outside counsel, rather than Sandra DeBow,
    to conduct the investigation, and he and DeBow had a heated
    argument about this subject at some point.
    8
    another two tours held in abeyance pending no further
    misconduct.5   Pender served his two-tour suspension between
    August 30 and September 6.6
    On September 10, four days after he completed his
    suspension, Pender was promoted to temporary fire captain.7
    Alston learned of the promotion on September 15 and immediately
    called DeBow to voice his objection, particularly given Skerry's
    representations at the July 30 meeting that Pender would not be
    promoted.   Alston also expressed his agitation with Pender's
    promotion when speaking with Skerry on October 12.
    b.    Subsequent incidents in 2010.   Before Alston returned
    to work, Skerry met with the officers to address rumors of
    backlash against Alston after Pender's transfer from the
    station.    Skerry told the officers that the town had zero
    5 The board also ordered Pender's permanent transfer from
    that station and required mediation with Alston, anger
    management training, and diversity training.
    6 Pender's two-tour suspension equated to a loss of forty-
    two hours of pay. In 2013, however, Pender and the town entered
    a settlement agreement in which the town gave Pender forty-two
    hours of vacation time. Pender alleged that this time was the
    result of long-standing issues over vacation time with the town
    and not related to his 2010 suspension, but neither Pender nor
    the town was able to provide any documentation to support that
    contention.
    7 Pender was promoted as part of a series of promotions to
    fill vacancies after a deputy chief position opened. His name
    was at the top of the civil service list for the temporary
    captain position.
    9
    tolerance for discrimination or retaliation and that a
    firefighter had exercised his right to file a complaint and
    should be treated cordially when he came back to work.    Alston
    returned to work on September 21, 2010.
    Two days after Alston returned, Firefighter Joseph Canney
    posted a message on the union's blog.     The commission found that
    the post was referring to Alston.   The post stated:
    "FACELESS COWARD
    "by Joe Canney
    "To the faceless coward who for no good reason, except of
    course his own self interest leaked to the media about one
    of our BROTHER"s [sic] alleged acts of misconduct on what
    should have been the proudest day of their professional
    lives is ________. I honestly can't even find an
    appropriate word for it. I have been around this job a
    long time and seen and heard a lot, but this even exceeds
    my wildest expectations of someones [sic] having a personal
    agenda to destroy another. This union went through this
    type of personal, meritless attacks before and it almost
    destroyed us, don't let this ever happen again, for all our
    sakes!"
    Alston reported the post to Skerry, and Skerry told him that he
    would ask the union to remove the post.    The town did not
    investigate the post or Canney and took no further action
    related to the post.
    In November 2010, Alston was transported by ambulance to a
    hospital after becoming highly agitated by the driving
    assignments made by his lieutenant at work.    Alston was upset
    that he was assigned to a particular vehicle and a less senior
    10
    probationary firefighter had been assigned to the other vehicle.
    The probationary firefighter was Pender's nephew.   When Alston
    expressed his displeasure with the assignments, another
    firefighter responded that the assignments had nothing to do
    with Pender.   This comment enraged and agitated Alston, and he
    agreed to be taken to a hospital.   While in the hospital, Alston
    tested positive for cocaine and admitted that he had used it
    recently for the first time in twenty years.    Alston also
    disclosed that he had started smoking marijuana in July to deal
    with his anger and anxiety and that he had lost forty pounds
    over the preceding few months due to his loss of appetite and
    stress from work.
    Beginning in late 2010, Alston was diagnosed on numerous
    occasions with "adjustment disorder."8   Notes from a social
    worker interview on October 14, 2010, reveal that Alston
    reported experiencing racism at work and explained that his
    anger was exacerbated by the way in which his supervisors and
    colleagues responded to the incident.    He raised similar
    concerns with treatment providers in November and December 2010
    as well and continued to do so in the ensuing months.
    8 One of the psychiatrists who examined Alston described
    adjustment disorder as "a DSM-5 diagnosis in which a person has
    a psychological response to specific stressors, however the
    response is more severe or lasts longer than one would normally
    expect."
    11
    c.    Other allegations by Alston.   Alston filed a complaint
    with the Massachusetts Commission Against Discrimination (MCAD)
    on May 24, 2012.     He alleged that the town discriminated against
    him by promoting Pender after he used the racist slur and that
    the town handled the incident differently because of Alston's
    race.     In an amended complaint filed on November 19, Alston
    alleged that he had been "shunned, isolated and mocked by his
    fellow firefighters at the direction and instruction of his
    superiors for three years with significantly worsening
    conditions" and that he had "made repeated complaints to his
    chiefs and human resources on a monthly, if not weekly basis"
    through 2011 and early 2012.9    The town attempted to investigate
    the claims in Alston's amended MCAD complaint, but Alston
    refused to participate in the investigation.     The town could not
    find any corroboration for his allegations.
    On at least two occasions, Pender and Alston spoke in
    person about the voicemail.10    After each conversation, Pender
    took transcript-like notes to summarize the conversations, both
    of which he gave to DeBow on November 19, 2013.     During the
    first conversation, which took place in February 2011, Pender
    9 Alston ultimately withdrew his MCAD complaint and chose to
    pursue a lawsuit in court.
    10Alston approached Pender and initiated the conversation
    on each occasion.
    12
    told Alston, "I don't know how we can be good Gerald, you
    destroyed my life and ruined my career.     But I'm glad you're
    good. . . .    I tried to tell you when we talked on the phone
    that if you went to the Chief this would create a huge shit
    storm."     Six days later, Alston reached out to his psychiatrist,
    Dr. Michael Kahn, to say that he was "very depressed, anxious,
    sleeping badly, crying, [and] not focusing."
    On the second occasion, in late October 2013, Pender told
    Alston that his name and his family's name were being dragged
    through the mud and that Alston's lawsuit against the town "was
    a bunch of lies" with "very little truth in it."     Pender also
    said that his use of the slur was the result of road rage, which
    "can be a side effect of [posttraumatic stress disorder], which
    [he] had been treated for after a bad fire the previous year."
    Pender also questioned Alston about statements in the lawsuit
    indicating that Alston said that Pender should not have been
    promoted.     On that same day, Alston reached out to his
    psychiatrist and reported that he felt like "beating someone up"
    and was "very focused on . . . wanting to get retribution and
    satisfaction for his having been called a racial slur allegedly
    two to three years ago."
    On May 1, 2013, Chief Paul Ford, the fire chief who
    succeeded Skerry, had recommended Pender for permanent promotion
    to captain.     With regard to how the voicemail incident affected
    13
    his considerations, Ford later testified in a deposition, "I
    mean, we all know that he said something he should [not] have.
    . . .   I looked at that he was disciplined, so, sort of paid his
    price."   The board permanently promoted Pender to captain on May
    7.   In his new role, Pender served as captain of training, which
    he described as the second in command of training new
    firefighters.     When training new recruits, Pender would tell
    them "[his] side of the story" regarding the voicemail incident
    and that what they heard about the incident from the media "is a
    bunch of lies."
    On June 17, 2013, Alston commenced a civil action against
    the town in the Superior Court in Norfolk County (Norfolk
    litigation).     The action was based on the same allegations as in
    his amended MCAD complaint and alleged discrimination under
    G. L. c. 151B.    During discovery, Alston provided the following
    details on his work environment in response to interrogatories:
    "I was sent to Station 4 in December of 2011 or January of
    2012. When I arrived I entered the kitchen and said 'good
    morning guys.' One of several firefighters replied. I
    approached one firefighter to shake his hand at which point
    he stood up and walked away. I worked twenty-four hours.
    Prior to finishing my shift I went to the dining area to
    find out when dinner would be held. I found all of the
    firefighters on duty eating together as is the norm. I
    asked why I hadn't been told that dinner was happening and
    they replied 'what are you talking about.'
    "The next morning I woke up and went to breakfast where
    several firefighters were sitting with Lt. Pender. Again,
    I stated 'good morning guys' and once again no one
    responded. When I began to prepare my breakfast they left
    14
    the room. This was the standard response each and every
    time I worked in a station other than my usual Station Five
    for several years, until recently when this case was
    publicized in a local newspaper article.
    " . . .
    "Prior to the incident with Lt. Pender I attended many
    family social events for my fellow firefighters including
    weddings, parties, cookouts, Baptisms, graduations etc.,
    etc. After the Lt. Pender incident I was never invited to
    those events. Before the Lt. Pender incident I was proud
    and privileged to serve as the singer of the national
    anthem at graduations and retirement services. After the
    Lt. Pender incident, to this day, I have never been invited
    to participate in those ceremonies in any way."
    This case was dismissed in July 2014 because of Alston's
    noncompliance with discovery requests.11
    d.    "Leave" incident.   On December 18, 2013, Alston told a
    lieutenant that he planned to ask for a transfer to another
    station.    The next day, as Alston was preparing to end his
    shift, he found the word "Leave" written on the door to his seat
    on the fire engine under his jacket.     Alston photographed the
    message and told several nearby firefighters about it.     Alston
    told these firefighters that he was not going to put up with
    this anymore and that he had kept quiet for a long time, and
    said something to the effect of "shooting up the place."       When
    he returned for his next shift several days later, Alston
    addressed the group of firefighters at his station.    As he was
    11Alston's attempts to obtain relief from the judgment were
    denied in July 2015.
    15
    speaking, he became very agitated and said, "[P]eople go postal
    over matters like this."    The two lieutenants at the station
    concluded that he was likely just "blowing off steam" but
    reported the statements to their superior.    Ford spoke directly
    with Alston at the station, and Alston became extremely agitated
    as they spoke.    Alston eventually told the chief and deputy
    chief, "Look, he's my friend, and you're my friend, and even you
    could get caught in a cross-fire."    Ford told Alston to go home
    that day.    When they spoke the next day, Alston agreed that he
    was not in a good place with regard to his mental health and
    agreed to be evaluated by the town's psychiatrist, Dr. Andrew
    Brown.    On December 27, 2013 -- five days after Alston had made
    the "postal" and "shooting" comments -- the chief told Alston he
    was not allowed on town property until Brown completed his
    evaluation.12    The town's police department circulated a flyer to
    all of its officers on around December 27 with Alston's
    photographs and description and information reflecting Alston's
    comments about "going postal."
    e.   Evaluations and failed attempts to return to work.
    Brown concluded his first fitness for duty evaluation of Alston
    12Brown evaluated Alston on January 6, 2014. Brown told
    the chief and DeBow soon thereafter that Alston did not pose any
    threat to himself or others. At this point, the stay away order
    against Alston was withdrawn. Alston, however, never returned
    to work after December 22, 2013.
    16
    on January 21, 2014, about one month after Alston's comments at
    the station.   Brown told Ford and DeBow that Alston did not pose
    any threat to himself or others.     Brown determined that Alston's
    ability to regulate his emotions was impaired and that this
    compromised his capacity to perform consistently the duties of a
    firefighter.     Brown opined that Alston needed psychiatric
    treatment to address this impairment.     Over the next few months,
    Brown and Kahn continued to evaluate Alston and communicate with
    each other about Alston's condition.
    On March 19, 2014, Alston submitted a written request for a
    transfer to a smaller station.     Around the same time, the town
    received Alston's medical records from his November 2010
    hospital visit through discovery in Alston's lawsuit in the
    Norfolk litigation.     These records revealed Alston's cocaine and
    marijuana use.
    On May 14, 2014, DeBow released two investigatory reports
    related to the December 2013 incident.     One report considered
    whether the "Leave" writing violated the town's
    antidiscrimination policy.     DeBow concluded that it could not be
    determined who had written "Leave" or why.     The report also
    suggested, without any factual basis, that
    "the possibility cannot be discounted that the word 'Leave'
    was written by a member of the . . . fraternity to which
    the truck had made a run the previous evening or some other
    neighbor or member of the public passing by who saw a ready
    canvas of salt and sand and took the opportunity to write
    17
    the word 'leave.' Again, there is no evidence to establish
    that this scenario occurred nor is there any evidence that
    it did not occur."
    In the other report, DeBow concluded that Alston violated
    the workplace safety policy with his "shooting" and "going
    postal" comments.    DeBow found that these comments "caused
    [Alston's] co-workers to be reasonably afraid of violent acts in
    the workplace."     The town imposed a two-tour suspension and a
    return to work plan on Alston.     The chief wrote to Alston that
    he would need to meet several conditions to return to work.13
    The chief also told Alston that his transfer request "will be
    addressed upon your return to duty."
    Alston met with Kahn on October 7, 2014.    Kahn conveyed to
    the town that Alston was "angry at everyone," "in desperate
    financial straits," "living out of his car," upset that the
    Norfolk litigation had been dismissed, and concerned that Brown
    was lying to him.    The town informed Alston that he had used up
    his available leave on October 23.     On November 24, Alston and
    his attorney, accompanied by some of Alston's supporters, showed
    13Those conditions were (1) regular and ongoing psychiatric
    treatment; (2) execution of a release authorizing the town to
    discuss his treatment and progress with his provider; (3)
    completion of an anger management course; (4) satisfactory
    reevaluation of his fitness to return to duty by a town
    psychiatrist; and (5) random urine drug testing for twenty-four
    months upon his return to work. Alston satisfied each of the
    first three conditions in the following months. Around this
    time, his complaint in the Norfolk litigation was dismissed.
    18
    up for a meeting with the fire chief and DeBow.    The meeting did
    not go forward, however, as Alston and his attorney insisted
    that the supporters be allowed to be present.     On the next day,
    November 25, DeBow sent Alston a letter that faulted Alston for
    not attending meetings at which his return to work (with or
    without accommodations) would be discussed, gave Alston until
    December 4 to identify reasonable accommodations for his return,
    and notified Alston that he had to attend a follow-up evaluation
    on December 5.   Later, on December 19, a member of the board
    wrote a letter to Alston that stated:
    "The Board of Selectmen acknowledged more than four years
    ago, and this Board acknowledges today, that unspeakable
    words were left on your voicemail that should never have
    been said. We acknowledge the deep hurt that those words
    caused you, and we acknowledge the wrongdoing of your
    supervisor. We are also informed that the supervisor who
    uttered those words to you and was formally disciplined for
    the incident offered his apology to you, and has since
    repeatedly expressed remorse and regret for his conduct."
    f.   Evaluation by Dr. Price.   Dr. Marilyn Price conducted
    the follow-up evaluation of Alston on February 12, 2015.14    Price
    met with Alston for about three hours and reviewed all of his
    medical records.   She described her role as "to say can [Alston]
    go back and work and under what circumstances can he go back to
    work."
    14The town replaced Brown with Price because Alston no
    longer trusted Brown. Alston's concern was partially based on
    the fact that Brown did not disclose that he was a former
    student of Kahn, Alston's personal psychiatrist.
    19
    As several other providers had previously done, Price
    diagnosed Alston with adjustment disorder.    She identified four
    stressors that affected Alston:    the voicemail from Pender;
    Pender's promotion to temporary captain in September 2010; the
    reference to the Pender incident by a superior in November 2010;
    and discovering the word "Leave" under his jacket in December
    2013.   Price found that "[h]earing a racial slur from a
    Lieutenant he trusted was especially troubling to Firefighter
    Alston because it called into question how he was really
    perceived by his fellow firefighters and raised concern about
    whether others would have his back in dangerous situations."
    She explained that the effect of these stressors was
    "perpetuated" because legal issues and negotiations "keep the
    stressor alive, essentially."     She further explained, "Unless
    the work environment can be modified so that Firefighter
    Alston's level of stress is decreased, it is very unlikely that
    he would be able to work effectively and have the level of trust
    of his fellow firefighters that is required."    Price also gave
    great weight to the fact that Alston said that he wanted to
    return to work.
    Price concluded that Alston could return to work if three
    conditions were met.   First, Alston would have to receive
    monthly treatment from a psychiatrist and weekly treatment with
    a therapist.   Second, there would have to be reasonable
    20
    workplace accommodations that reduced the level of stress for
    Alston.   Third, Alston would have to undergo random drug
    screening for two years after he returned to work.    The town
    sent Price's report to Alston on March 25, 2015.
    After Price completed her evaluation and issued her report,
    the town attempted to schedule meetings and communicate with
    Alston on numerous occasions regarding his return to work.
    Beginning in August 2015, the town reached out to Alston or his
    attorney a number of times with little success.    For example,
    after the town identified March 7, 2016, as a return to work
    date, it scheduled Alston for a drug test on February 10, but
    Alston failed to appear.   Then, after demanding to Ford that he
    be allowed to meet with the full board in March 2016, Alston and
    his attorney did not respond to subsequent calls and letters
    from Ford and his successor.   Alston and his attorney continued
    to ignore the department's attempts to contact Alston and
    schedule meetings through August 2016.
    Alston commenced a lawsuit in Federal court in December
    2015 against the town, the union, and various town officials,
    alleging civil rights violations under Federal law.    A Federal
    judge concluded that Alston could not bring any claims that he
    either brought or could have brought in the Norfolk litigation.
    Alston v. Brookline, 
    308 F. Supp. 3d 509
    , 516 (D. Mass. 2018).
    The judge granted summary judgment in favor of the town on
    21
    Alston's remaining claims, concluding that there was no genuine
    dispute of material fact that the town did not discriminate
    against Alston.     Alston vs. Brookline, U.S. Dist. Ct., No. 15-
    13987-GAO (D. Mass. Apr. 2, 2020).    Rather, the judge concluded
    that the town fired Alston because "he repeatedly declined to
    attend meetings he was invited to or present evidence of his own
    about his ability to return to work."    
    Id.
        Alston's appeal from
    the summary judgment decision currently is pending.
    g.   Pender's third promotion and Alston's termination.      On
    June 16, 2016, Pender was recommended for another promotion to
    temporary deputy fire chief.    Pender provided the board with a
    written statement as it considered the recommendation on June
    21.   In that statement, Pender told the board that he had
    "apologized countless times for [his] action [on the day he left
    the voicemail]" and stated, "I don't know what happened back
    then between Mr. Alston and the Town, but apparently he felt
    slighted somehow.    His course of action, which gets the most
    attention, is to drag me into it all over again."      Several
    firefighters spoke on Pender's behalf, decrying the "narrative
    fabricated" against Pender and the town.       One of the deputy
    chiefs said, "[W]e should have all moved on" and lamented the
    "smear campaign" led by "a few people with a separate agenda."
    At a subsequent hearing on July 12, several members of the
    board endorsed Pender's promotion.    One member emphasized,
    22
    "Brookline needs to move on and cease debating past rights and
    wrongs.    A better future is not possible if we remain trapped in
    conversations about perceived past misdeeds or mistakes."
    Another stated that
    "hav[ing] 'zero tolerance' for any use of the N word, or
    any of the other words that have vile and hurtful histories
    and usages, would not be good policy where that use is a
    one-time and isolated act. Such an act warrants
    discipline, but the use of racist slur six years ago,
    without more, cannot be justification to permanently
    preclude someone form [sic] the benefits of employment he
    would otherwise be entitled to receive. . . . [Pender,]
    after having made this grievous mistake, did come around
    and begin to repair the damage he caused . . . ."
    Pender's promotion became effective a few days later, on July
    18.
    On July 21, 2016, DeBow informed Alston that the town had
    scheduled a return to work evaluation for him on August 2.     When
    Alston failed to appear for the evaluation, the town notified
    Alston of his contemplated discharge on August 17.    An outside
    hearing officer held a hearing on August 30 and issued a report
    recommending that the town terminate Alston.    The town notified
    Alston of the hearing officer's findings on September 30 and
    told him that his termination would be considered at the October
    5 board meeting.    The board voted to terminate Alston at that
    meeting.15
    Alston had been absent from work on various forms of
    15
    leave since December 22, 2013.
    23
    2.      Procedural history.   Alston appealed from his
    termination to the commission.     In 2017, the commission upheld
    his termination and dismissed Alston's appeal in a summary
    decision.    The commission concluded that the town "had
    reasonable justification to conclude that [Alston] was not then
    capable of performing the duties of his position as a . . .
    Firefighter and that there was no reasonable basis to expect his
    return to duty at any time in the foreseeable future, with or
    without accommodations."     Alston appealed from this order to the
    Superior Court under G. L. c. 30A, § 14.      The judge vacated the
    commission's order and remanded it to the commission for an
    evidentiary hearing.     The judge, interpreting the civil service
    law, held that "an employer lacks 'just cause' if a termination
    would not have occurred but for the employer's racially hostile
    environment, maintained in violation of basic merit principles."
    The judge also reasoned that "an employer has no right to demand
    proof that an otherwise fit employee can perform job duties in a
    racially hostile environment."     The judge concluded that the
    commission could not decide the issues in a summary decision and
    remanded the case to the commission for the evidentiary hearing.
    On remand, the commission conducted a ten-day evidentiary
    hearing.    It heard testimony from fourteen witnesses and
    received 280 exhibits.     As discussed more fully infra, the
    commission concluded that the town lacked just cause to
    24
    terminate Alston and ordered his reinstatement.     The town then
    appealed from the commission's order to the Superior Court.       The
    Superior Court judge granted Alston's motion for judgment on the
    pleadings.    The town appealed.
    3.      Discussion.   The town raises numerous issues on appeal.
    At the heart of the town's appeal, however, are two core
    arguments.    The town first argues that the commission exceeded
    its authority by considering claims of discrimination that must
    instead be addressed under G. L. c. 151B, and by ignoring the
    preclusive effect of prior litigation.     The town then argues
    that the commission's determination that the town lacked just
    cause to terminate Alston is not supported by substantial
    evidence.    Rather, according to the town, the evidence
    demonstrates that the town had just cause to terminate Alston
    because he could not perform the duties of a town firefighter
    and failed to comply with the town's return to work
    requirements.    We address each argument in turn infra, starting
    with the two relevant statutes and explaining the overlapping
    protections they provide, how the statutes interact with each
    other, and the remedies each furnishes.
    a.      Relevant statutory language.   Under the civil service
    law, G. L. c. 31, an appointing authority cannot discharge or
    remove an employee without "just cause."     G. L. c. 31, § 41
    ("Except for just cause . . . , a tenured employee shall not be
    25
    discharged . . . [or] removed . . .").   Although the civil
    service law does not define what constitutes "just cause," we
    have held that it exists where the employee has committed
    "substantial misconduct which adversely affects the public
    interest by impairing the efficiency of the public service."
    Doherty v. Civil Serv. Comm'n, 
    486 Mass. 487
    , 493 (2020),
    quoting Police Comm'r of Boston v. Civil Service Comm'n, 
    39 Mass. App. Ct. 594
    , 599 (1996).   Such misconduct is generally
    understood to include misconduct at work, e.g., Doherty, supra
    at 489 (commission found just cause for discipline where
    employee was "rude" and "unprofessional" and charged with
    unsatisfactory performance), or a failure to perform duties or
    meet job requirements, see Cullen v. Mayor of Newton, 
    308 Mass. 578
    , 581 (1941) (civil service law permits "removal of those who
    have proved to be incompetent or unworthy to continue in the
    public service").   See also Nolan v. Police Comm'r of Boston,
    
    383 Mass. 625
    , 630 (1981) (police department "has the authority
    and duty to determine a police officer's fitness to perform his
    duties or to return to full working status").   When reviewing
    civil service disciplinary actions, the civil service law
    mandates that the commission reverse an action of the appointing
    authority "if the employee, by a preponderance of evidence,
    establishes that said action was based . . . upon any factor or
    conduct on the part of the employee not reasonably related to
    26
    the fitness of the employee to perform in his position."     G. L.
    c. 31, § 43.
    In determining whether the decision was based on improper
    factors, we must also recognize that the civil service law
    expressly mandates that decisions be consistent with "basic
    merit principles."     Massachusetts Ass'n of Minority Law
    Enforcement Officers v. Abban, 
    434 Mass. 256
    , 264 (2001)
    (fundamental purpose of civil service law is "to ensure
    decision-making in accordance with basic merit principles").
    "Basic merit principles" include "assuring fair treatment of all
    applicants and employees in all aspects of personnel
    administration without regard to political affiliation, race,
    color, age, national origin, sex, marital status, handicap, or
    religion and with proper regard for privacy, basic rights
    outlined in [G. L. c. 31] and constitutional rights as citizens"
    (emphases added).    G. L. c. 31, § 1.
    Despite this express language directed at fair treatment of
    all employees regardless of race, the town contends that G. L.
    c. 151B provides the exclusive remedy to address the type of
    misconduct at issue.    This argument oversimplifies the
    relationship between the two statutes.     Chapter 151B
    specifically prohibits a broad range of discrimination in
    employment on the grounds of race, sex, sexual orientation,
    gender identity, national origin, disability, or religion.     See
    27
    G. L. c. 151B, § 4.     It "creates an administrative procedure for
    the enforcement of antidiscrimination statutes of the
    Commonwealth."    See Charland v. Muzi Motors, Inc., 
    417 Mass. 580
    , 582 (1994).     As relevant here, employees can bring a claim
    against their employer under c. 151B for a hostile work
    environment.     See College-Town, Div. of Interco, Inc. v.
    Massachusetts Comm'n Against Discrimination, 
    400 Mass. 156
    , 162
    (1987) ("The discrimination prohibited by G. L. c. 151B,
    § 4 [1], encompasses a work environment pervaded by abuse and
    harassment").     An employee may also bring a claim of
    retaliation.     See, e.g., Psy-Ed Corp. v. Klein, 
    459 Mass. 697
    ,
    707 (2011) (employee has claim for retaliation under c. 151B
    where employee engaged in protected conduct, he or she suffered
    some adverse action, and causal connection exists between
    conduct and adverse action).16    Chapter 151B provides a
    16 Retaliation is a different claim from discrimination
    under G. L. c. 151B. See Verdrager v. Mintz, Levin, Cohn,
    Ferris, Glovsky, & Popeo, P.C., 
    474 Mass. 382
    , 405 (2016). "An
    employee bringing a retaliation claim is not complaining of
    discriminatory treatment as such, but rather of treatment that
    'punish[es]' her for complaining of or otherwise opposing such
    discriminatory treatment." 
    Id.,
     quoting Ruffino v. State St.
    Bank & Trust Co., 
    908 F. Supp. 1019
    , 1040 (D. Mass. 1995).
    Therefore, a "claim of retaliation may succeed even if the
    underlying claim of discrimination fails, provided that in
    asserting her discrimination claim, the claimant can 'prove that
    [she] reasonably and in good faith believed that the [employer]
    was engaged in wrongful discrimination'" (alterations in
    original). Psy-Ed Corp., 
    459 Mass. at
    706–707, quoting Abramian
    v. President & Fellows of Harvard College, 
    432 Mass. 107
    , 121
    (2000).
    28
    comprehensive set of remedies that address discrimination,
    harassment, and retaliation, including those based on race.17
    In this case we must determine how G. L. cc. 31 and 151B
    interact in cases involving civil service employees.   Generally,
    "[i]n the absence of explicit legislative commands to the
    contrary, we construe statutes to harmonize and not to undercut
    each other."   Ryan v. Mary Ann Morse Healthcare Corp., 
    483 Mass. 612
    , 620 (2019), quoting School Comm. of Newton v. Newton Sch.
    Custodians Ass'n, Local 454, SEIU, 
    438 Mass. 739
    , 751 (2003).
    We "attempt to interpret statutes addressing the same subject
    matter harmoniously, 'so that effect is given to every provision
    in all of them.'"   Green v. Wyman-Gordon Co., 
    422 Mass. 551
    , 554
    (1996), quoting 2B Singer, Sutherland Statutory Construction
    § 51.02, at 122 (5th ed. 1992).   In fact, in an analogous
    context, we concluded that the existence of a distinct, but
    overlapping, statutory scheme permitted an aggrieved party to
    pursue a remedy under either the civil service law or the
    17Both courts and the MCAD have broad authority to remedy
    c. 151B violations. G. L. c. 151B, § 5. The statute includes a
    nonexhaustive list of remedial actions that the MCAD can take,
    including "hiring, reinstatement or upgrading the employees,
    with or without back pay, or restoration to membership in any
    respondent labor organization." Id. See Stonehill College v.
    Massachusetts Comm'n Against Discrimination, 
    441 Mass. 549
    , 567,
    cert. denied sub nom. Wilfert Bros. Realty Co. v. Massachusetts
    Comm'n Against Discrimination, 
    543 U.S. 979
     (2004). Damages are
    also available, including compensatory damages, front pay,
    emotional distress damages, and punitive damages.
    29
    related statute.   See Fernandes v. Attleboro Hous. Auth., 
    470 Mass. 117
    , 126 (2014) ("Although both the civil service law and
    the Wage Act address wrongful conduct arising in the employment
    context, they have distinct purposes and, as a consequence,
    provide different remedies for the violation of their statutory
    mandates").
    In the instant case, G. L. c. 151B provides specific
    guidance on how it interrelates with other statutes.   General
    Laws c. 151B, § 9, provides:
    "This chapter shall be construed liberally for the
    accomplishment of its purposes, and any law inconsistent
    with any provision of this chapter shall not apply, but
    nothing contained in this chapter shall be deemed to repeal
    any provision of any other law of this commonwealth
    relating to discrimination; but, as to acts declared
    unlawful by [G. L. c. 151B, § 4], the administrative
    procedure provided in this chapter under [§ 5] shall, while
    pending, be exclusive; and the final determination on the
    merits shall exclude any other civil action, based on the
    same grievance of the individual concerned." (Emphases
    added.)
    The language as to repeal and exclusivity is carefully
    drafted here.   As the foregoing indicates, nothing about G. L.
    c. 151B was intended to repeal any portion of any existing law
    "relating to discrimination," which includes the civil service
    law protection against discharges without just cause and
    enforcement of basic merit principles.18   Instead, G. L. c. 151B
    18The civil service system has been in existence since at
    least 1884. See St. 1884, c. 320. "Race" was added to the
    definition of "basic merit principles" in 1981. See St. 1981,
    30
    proceedings are exclusive as to "acts declared unlawful" by
    c. 151B only when administrative proceedings are pending before
    the MCAD, or a final determination on the merits has been made
    "based on the same grievance."   This prioritization regarding
    "acts declared unlawful by [G. L. c. 151B, § 4,]" makes sense
    given that G. L. c. 151B is designed specifically to address
    discrimination and provides a comprehensive remedial structure
    to rectify discrimination.   See Green, 422 Mass. at 555 (G. L.
    c. 151B is "broad and comprehensive remedial scheme").     Here,
    however, Alston's only MCAD proceeding ended several years
    before he sought review of his termination with the commission.
    There was no proceeding pending under G. L. c. 151B, § 5, when
    Alston appealed from his termination to the commission.
    Therefore, neither § 9 nor G. L. c. 151B more broadly bar the
    commission from considering conduct related to discrimination
    when reviewing whether the town had just cause to terminate
    Alston.
    Moreover, interpreting the civil service law in a way that
    permits the commission to consider racist or retaliatory
    statements and acts, and the municipality's improper response to
    those statements and actions, in the commission's just cause
    determination does not displace or undermine the purpose served
    c. 767, § 10. General Laws c. 151B originally was enacted in
    1946. See St. 1946, c. 368, § 4.
    31
    by G. L. c. 151B.    The just cause analysis may overlap with, but
    remain different from, a determination of discrimination.     The
    commission here focused on arbitrary and capricious decision-
    making in response to the racist statement and apparently
    retaliatory acts without making express findings of
    discrimination or retaliation as defined by G. L. c. 151B.    It
    need not do so to find a lack of just cause.19   Racist and
    retaliatory acts, combined with an arbitrary and capricious
    response by the employer, may be found to be sufficient to
    support a determination that the discharge was unjustified.    A
    civil service employee has greater job protection than most
    19   As the hearing officer explained:
    "It is not necessary to conclude whether the Town violated
    the state's anti-discrimination law to decide this appeal
    and I have not attempted to do so here. The Commission is
    not mandated to function as an alternative to MCAD or the
    Court as an adjudicator of the rights of those who have
    experienced discrimination or retaliation in violation of
    their civil rights or other laws. However, when a civil
    service appointing authority commits acts which are
    fundamentally unfair and fall within the penumbra of the
    prohibited conduct of those laws, it is appropriate for the
    Commission to take notice of that misconduct in order to
    fulfil the statutory mandate to assure 'fair treatment' of
    civil service employees, free from 'arbitrary and
    capricious' acts, 'without regard' for an employee's 'race'
    or other protected status, and 'with proper regard' for
    civil service law and an employee's 'constitutional rights,
    as citizens.' G. L. c. 31, § 1."
    32
    other employees as reflected in the just cause provision, and
    additional procedural and job-specific rights.20
    From the foregoing, it is clear that the commission's
    mandate is to protect civil service employees from termination
    from employment for reasons that violate basic merit principles.
    As most relevant here, the commission may determine that an
    employee has been subject to, and rendered unfit by, racist and
    retaliatory acts and an arbitrary and capricious response to
    those acts by the municipality.   See Malloch v. Hanover, 
    472 Mass. 783
    , 799-800 (2015) (promotion and bypass decision tainted
    by gender bias would violate basic merit principles).    The
    commission can further determine that, in these circumstances,
    termination of such an employee violates basic merit principles.
    More specifically, the commission may find that the employer is
    responsible for the intolerable workplace conditions, including
    racist and retaliatory acts, that have rendered the employee
    unfit to perform his or her duties and resulted in the
    employee's discharge, and therefore the employee's unfitness is
    not just cause for his or her termination.   Cf. Salvi v. Suffolk
    County Sheriff's Dep't, 
    67 Mass. App. Ct. 596
    , 606-607 (2006)
    20We need not decide today to what extent a decision on the
    merits rejecting a claim of discrimination under G. L. c. 151B
    by either the MCAD or a court would have preclusive effect on
    the commission's ability to consider discriminatory conduct as
    part of its analysis as to whether a municipality had just
    cause.

    (homophobic slurs, shunning, and inappropriate corrective action
    resulting in intolerable workplace conditions and deterioration
    of employee's mental health found to constitute constructive
    discharge).   Rather, the intolerable workplace environment that
    the municipality created or sustained is the cause of the
    employee's unfitness and unjust termination.   Cf. GTE Prods.
    Corp. v. Stewart, 
    421 Mass. 22
    , 34 (1995) (where employee
    resigns because of work environment created by employer that is
    "so difficult as to be intolerable," resignation treated as if
    employer terminated employee); Salvi, supra.   To reiterate, in
    making this determination, the commission has the authority to
    hear evidence and make findings based on the types of
    discriminatory and retaliatory statements and actions that are
    proscribed by G. L. c. 151B.21
    The town also argues that the commission is barred by claim
    preclusion and issue preclusion.   The town argues that Alston
    previously litigated his claims in the Norfolk litigation, and
    the judge's dismissal in that case bars Alston from relitigating
    his allegations of discrimination in this case.   "Claim
    21The town relies on our decision in Charland, 
    417 Mass. at 586
    , in which we held that "where applicable, G. L. c. 151B
    provides the exclusive remedy for employment discrimination not
    based on preexisting tort law or constitutional protections."
    As we have explained, however, Alston did not bring an
    employment discrimination claim against the town; rather, he
    contested whether the town had just cause to terminate him from
    his position.
    34
    preclusion makes a valid, final judgment conclusive on the
    parties and their privies, and prevents relitigation of all
    matters that were or could have been adjudicated in the action."
    DeGiacomo v. Quincy, 
    476 Mass. 38
    , 41 (2016), quoting Kobrin v.
    Board of Registration in Med., 
    444 Mass. 837
    , 843 (2005).
    "[C]laim preclusion requires three elements:    '(1) the identity
    or privity of the parties to the present and prior actions, (2)
    identity of the cause of action, and (3) prior final judgment on
    the merits.'"   DeGiacomo, supra, quoting Kobrin, supra.
    On the other hand, "[i]ssue preclusion 'prevents
    relitigation of an issue determined in an earlier action where
    the same issue arises in a later action, based on a different
    claim, between the same parties or [parties in privity with the
    same parties].'"     DeGiacomo, 476 Mass. at 42, quoting Kobrin,
    444 Mass. at 843.    "A party is precluded from relitigating an
    issue where '(1) there was a final judgment on the merits in the
    prior adjudication; (2) the party against whom preclusion is
    asserted was a party (or in privity with a party) to the prior
    adjudication; and (3) the issue in the prior adjudication was
    identical to the issue in the current adjudication,' was
    essential to the earlier judgment, and was actually litigated in
    the prior action."    DeGiacomo, supra, quoting Kobrin, supra.
    The judge below concluded that claim preclusion did not
    apply because Alston was not raising claims under G. L. c. 151B
    35
    as he had in the Norfolk litigation.      Similarly, the judge
    concluded that the Norfolk litigation did not determine any
    facts, and therefore, issue preclusion did not apply.
    We agree that neither claim nor issue preclusion applies
    here.      Claim preclusion clearly is inapplicable, as the two
    actions involve different claims.     The Norfolk litigation
    involved claims under G. L. c. 151B; the present case involves a
    challenge to Alston's termination under G. L. c. 31, §§ 41 and
    43.
    Issue preclusion also does not apply.     Even if an identical
    issue could be identified, which is doubtful here,22 "issue
    preclusion can be used only to prevent relitigation of issues
    actually litigated in the prior action" (emphasis added).
    Kobrin, 444 Mass. at 843-844.      There is no indication that the
    parties actually litigated the issues of discrimination and
    retaliation, as the case was dismissed as a discovery sanction.
    The Norfolk litigation involved allegations of racial
    22
    discrimination based on the voicemail and subsequent acts of
    retaliation prior to 2014; the present litigation involves a
    challenge to the town's termination of Alston without just cause
    in 2016. Although the pre-2014 discriminatory and retaliatory
    acts figured into the 2016 analysis, as discussed supra, the
    issue whether the town discriminated against Alston under G. L.
    c. 151B prior to 2014 is different from whether the town had
    just cause to terminate Alston in 2016 under G. L. c. 31, § 41.
    Thus, although the two cases involve some of the same underlying
    facts, the issues in each case appear to be distinct. See
    Kobrin, 444 Mass. at 843 (no issue preclusion where issues not
    identical).

    b.    Substantial evidence.    The decision of the commission
    "will be upheld unless it is 'unsupported by substantial
    evidence[,] . . . arbitrary or capricious, an abuse of
    discretion, or otherwise not in accordance with the law.'"
    Boston Police Dep't v. Civil Serv. Comm'n, 
    483 Mass. 461
    , 469
    (2019), quoting G. L. c. 30A, § 14 (7).    "Substantial evidence
    is 'such evidence as a reasonable mind might accept as adequate
    to support a conclusion.'"   Boston Police Dep't, supra at 474,
    quoting G. L. c. 30A, § 1 (6).     Importantly, we "give due weight
    to the experience, technical competence, and specialized
    knowledge of the agency, as well as to the discretionary
    authority conferred upon it."     G. L. c. 30A, § 14 (7).   "This
    standard of review is highly deferential to the agency on
    questions of fact and reasonable inferences drawn therefrom."
    Flint v. Commissioner of Pub. Welfare, 
    412 Mass. 416
    , 420
    (1992).   Accordingly, as the party challenging the commission's
    order here, the town "bears a heavy burden."     Spencer v. Civil
    Serv. Comm'n, 
    479 Mass. 210
    , 215 (2018).
    We begin with the commission's summary of its decision,
    which clearly and concisely encapsulates its findings of fact
    and legal analysis:
    "A white Brookline Fire Lieutenant made the racist comment
    'fucking [n-word]' to describe a motorist who the
    lieutenant believed to be black or Hispanic. That racist
    comment inadvertently ended up on the voice mail of the
    37
    lieutenant's employee, Gerald Alston, an African American
    firefighter in the Brookline Fire Department.
    "Town officials responded with a minor, short-term
    suspension of the lieutenant followed by his almost-
    immediate promotion. Thereafter, Town officials: granted
    further promotions of the lieutenant; failed to prevent
    retaliatory behavior against Firefighter Alston; and
    enabled the lieutenant to use his position to lobby many
    other members of the force against Firefighter Alston and
    paint himself as the victim.
    "These actions by the Town were arbitrary, capricious, and
    in violation of Firefighter Alston's rights under the civil
    service law to be treated fairly '. . . without regard to
    political affiliation, race, color, age, national origin,
    sex, marital status, handicap, or religion and with proper
    regard for . . . basic rights outlined in [the civil
    service law] and constitutional rights as citizens . . . .'
    G. L. c. 31, § 1. The Town's own actions and inactions
    were the reasons that made it impossible for Firefighter
    Alston to return to work, which formed the basis of the
    Town's decision to terminate his employment.
    "When a municipality's own violation of a tenured
    employee's rights has prevented the employee from returning
    to work, as here, the Town cannot use that inability to
    work as just cause for discharging the employee from his
    tenured position."
    We conclude that there is substantial evidence to support
    this decision; it is also a correct statement of the law.    For
    these reasons, we affirm.
    Beginning with the original incident, the commission's
    findings show that the board's handling of the use of racist
    language by Pender was woefully deficient and insensitive given
    the concerns raised by Alston about racist behavior and
    retaliation.   As the commission explained:
    38
    "The Town's failure to respond to the report of the racial
    epithet in a timely manner; their failure to impose a
    proper level of discipline; and their decision to
    repeatedly promote Mr. Pender showed that the Town failed
    to comprehend the seriousness of Mr. Pender's use of the
    racial epithet and the damaging impact it had on
    Firefighter Alston."
    Not only did it take weeks for the department to begin
    investigating the incident, but the board also then failed to
    conduct any meaningful inquiry into the incident, instead
    conducting what the commission described as "an informal
    discussion" with Pender and his attorney.23   It also disregarded
    23We emphasize today what should no longer need to be said
    in 2021 -- the use of "n----r" has absolutely no place in any
    workplace environment in the Commonwealth, including among those
    subject to the civil service laws. The Appeals Court has
    previously condemned the use of "n----r" in this context. See
    Green v. Harvard Vanguard Med. Assocs., 
    79 Mass. App. Ct. 1
    , 8
    (2011) (phrase "fucking [n----r]" is "disgusting, demeaning, and
    humiliating" and use of words and their "impact upon those to
    whom they are directed . . . is a grave matter"); Augis Corp. v.
    Massachusetts Comm'n Against Discrimination, 
    75 Mass. App. Ct. 398
    , 409 (2009) ("[This slur] inflicts cruel injury by its very
    utterance. It is degrading, it is humiliating, and it is
    freighted with a long and shameful history of humiliation, the
    ugly effects of which continue to haunt us all. The words have
    no legitimate place in the working environment -- indeed, they
    have no legitimate place -- and there is no conceivable
    justification for their use by a workplace supervisor"). Other
    courts have echoed these sentiments, emphasizing how harmful the
    word is. See, e.g., Ayissi-Etoh v. Fannie Mae, 
    712 F.3d 572
    ,
    580 (D.C. Cir. 2013) (Kavanaugh, J., concurring) (term "sums up
    . . . all the bitter years of insult and struggle in America"
    [citation omitted]); Hrobowski v. Worthington Steel Co., 
    358 F.3d 473
    , 477 (7th Cir. 2004) (courts "recognize that the [slur]
    can have a highly disturbing impact on the listener"); Spriggs
    v. Diamond Auto Glass, 
    242 F.3d 179
    , 185 (4th Cir. 2001) ("[f]ar
    more than a mere offensive utterance," term is "pure anathema to
    39
    the disciplinary recommendation of the chief of the department
    at the time and gave Pender a more lenient punishment.
    That Pender was promoted almost immediately after serving
    his suspension further compounded the initial failures.     Alston
    was shocked by Pender's promotion because he had been assured by
    the chief that Pender would not be promoted.   The town and the
    department have attempted to justify this promotion by arguing
    that it was automatic because Pender was at the top of the civil
    service list and that it was temporary.   As the commission
    emphasized, candidates at the top of the list easily can be
    passed over provided reasonable justification exists.     See
    Sherman v. Randolph, 
    472 Mass. 802
    , 804 (2015) ("Candidates at
    the top of the list . . . may be bypassed if the appointing
    authority chooses a candidate lower on the eligibility list
    based on reasonable justification").   The town or the department
    clearly had such justification here given Pender's recent
    actions.
    Thereafter, Pender was promoted at least two more times,
    further compounding Alston's sense that racism in his workplace
    was not being addressed.   As the commission emphasized:
    "After being promoted, Mr. Pender used his position as
    Captain of Training to tell his 'side of the story'
    African-Americans" [quotation omitted]); Monteiro v. Tempe Union
    High Sch. Dist., 
    158 F.3d 1022
    , 1034 (9th Cir. 1998) ("the most
    noxious racial epithet in the contemporary American lexicon").
    40
    regarding the incident to all new recruits, telling them
    that what they read in the local paper about this matter
    was 'a bunch of lies.' . . . This was not a momentary
    misstatement by Mr. Pender. Rather, both at the time, and
    years later, he would repeatedly make comments suggesting
    that his racist comment was overblown and, in turn, that
    Firefighter Alston had overreacted to the racist comment.
    Most troubling is that, over a period of years, Mr. Pender
    would reinforce that message to every new recruit of the
    Brookline Fire Department."
    The commission also described numerous instances of
    retaliatory behavior in the ensuing months and years that the
    town failed to investigate or discipline properly.   The town did
    nothing to investigative the union blog post -- which minimized
    the racist comment and retaliated against Alston for reporting
    it -- aside from asking that it be removed.   It also did nothing
    when Pender himself handed the town transcripts of conversations
    with Alston in which he "attack[ed]" Alston's decision to report
    the incident.   When referring to Pender's comments to Alston
    regarding his decision to report the incident, the commission
    observed that "[i]t is difficult to imagine a more stressful
    situation for an employee than when a supervisor, who had
    recently made a racist comment, is now attacking the employee
    for reporting it."   Similarly, the commission identified a
    number of ways in which it found that the town acted in bad
    faith.   One example was the town's unfounded, if not farcical,
    suggestion in its official investigative report of the incident
    that "Leave" could have been written by a fraternity member or a
    41
    passerby despite "there [being] no evidence to establish this
    scenario occurred."
    The commission also pointed to evidence from the members of
    the board.   Its findings show that "[d]uring the public comment
    session, Town officials and employees repeatedly referenced the
    remorse and apologies of Mr. Pender and appeared to explicitly
    call out Firefighter Alston for his inability to 'move on,'"
    ignoring that "Pender had, on multiple occasions, verbally
    attacked Firefighter Alston for reporting the incident and
    repeatedly minimized his misconduct to fellow firefighters,
    including all new recruits," and that other members of the
    department had engaged in retaliatory behavior against Alston in
    support of Pender.
    The commission also made findings regarding the effect of
    these actions on Alston:   "After reviewing all of the evidence,
    including the testimony of Firefighter Alston, [the commission
    has] concluded that Mr. Pender's use of the racial epithet
    'fucking [n----r],' coupled with subsequent actions and
    inactions by Town officials at all levels, which compounded the
    racist comment into an avalanche of unfair, arbitrary,
    capricious and retaliatory behavior that infringed on
    Firefighter Alston's civil service rights, made it impossible
    for him to perform his job as a Brookline firefighter."   More
    particularly, the commission credited the expert testimony from
    42
    Price to the extent that she concluded that "hearing a racial
    slur from a Lieutenant he trusted was especially troubling to
    Firefighter Alston because it called into question how he was
    really perceived by his fellow firefighters and raised concern
    about whether others would have his back in dangerous
    situations."   Furthermore, the commission adopted the expert's
    determination that "Alston developed psychological symptoms in
    response to hearing the racial slur from his Lieutenant" and
    that Alston was diagnosed properly in 2015 with adjustment
    disorder.   The commission did not, however, "find that the
    evidence supported [Price's] conclusion that Firefighter Alston
    would be able to return to work upon meeting the conditions
    outlined in her report."   The commission rejected this part of
    her testimony because "she simply did not have the benefit of
    the entire record that was presented to the Commission through
    two hundred eighty (280) exhibits and fourteen (14) witnesses
    over ten (10) days of hearing."
    In light of these findings, we conclude that there is
    substantial evidence to support the commission's determination
    that the town acted arbitrarily and capriciously and in
    violation of "Alston's rights under the civil service law to be
    treated fairly 'without regard to . . . race.'"   Considering
    Pender's racist comment, the retaliatory actions, and the town's
    continuously insensitive and inappropriate, if not outright
    43
    discriminatory, responses, the commission's findings constitute
    "such evidence as a reasonable mind might accept as adequate to
    support" the conclusion that the town caused Alston's unfitness
    preventing his return to work.   See G. L. c. 30A, § 1 (6).    Cf.
    Salvi, 67 Mass. App. Ct. at 606-607.
    The town makes several arguments why the commission's
    conclusion was not supported by substantial evidence.   First,
    the town argues that the conclusion that Alston was prevented
    from returning to work was erroneous because the commission's
    findings demonstrate that the town terminated Alston after his
    absence from work for nearly two and one-half years and his
    failure to participate in the return to work process.   This
    argument ignores the key conclusion of the commission -- that
    Alston's inability to work was caused by the town's actions and
    inactions.   This is also the type of difficult, fact-specific
    determination that requires deference to the commission if it is
    supported by substantial evidence.   As we explained in Labor
    Relations Comm'n v. University Hosp., Inc., 
    359 Mass. 516
    , 521
    (1971):
    "A court may not displace an administrative board's choice
    between two fairly conflicting views, even though the court
    would justifiably have made a different choice had the
    matter been before it de novo. The judicial inquiry is
    limited to a determination whether within the record which
    was before the Commission and which it has sent to the
    court for review there is 'such evidence as a reasonable
    mind might accept as adequate to support' the Commission's
    conclusion . . . . If there is, the action of the
    44
    Commission must be affirmed even though the court would
    have reached a different result if it were originally in
    the position of the Commission." (Citations omitted.)
    The town does not dispute the findings on which the commission
    based its decision.   It simply argues that the commission should
    have reached a different conclusion about Alston's ability to
    return to work and the causes thereof based on those findings.
    To be sure, much of the conduct that the town points to as
    evidence of Alston's lack of fitness is also supported by
    evidence in the record.   Alston's extended absence from work,
    his drug use and mental health concerns, and his steadfast
    refusal even to meet with or speak to members of the department
    on the return to work process present serious concerns,
    especially for public safety workers, and provide justification
    for discipline or even termination from employment in other
    circumstances, where the commission has not found racist and
    retaliatory conduct in the workplace and that the employer's
    arbitrary and capricious responses to such conduct, all in
    violation of merit principles, rendered the employer responsible
    for such absences, drug use, or mental health problems.     We read
    the commission's decision here, in the context of the highly
    unusual facts of this case and Alston's particular mental
    illness, to excuse noncompliance with attendance and cooperation
    requirements.   That is not to say, however, that illegal drug
    use, or a failure to participate in a reasonable return to work
    45
    process, would not be just cause for discipline or termination
    under different circumstances.
    Ultimately, however, it is the job of the commission, not
    this court, to weigh the evidence before it and determine
    whether a municipality had just cause to terminate an employee.
    Our review is simply to determine whether the commission's
    decision is supported by substantial evidence.    See Brackett v.
    Civil Serv. Comm'n, 
    447 Mass. 233
    , 241 (2006).     See also Boston
    Police Dep't, 483 Mass. at 476.   Here, the commission's
    essential findings are supported by evidence in the record.    The
    commission provided detailed findings supporting its conclusion
    that racist comments and retaliatory actions and arbitrary and
    capricious responses by the town in violation of merit
    principles rendered Alston unfit and that there was not just
    cause for his discharge despite lack of cooperation with
    conditions imposed by the town.   The town therefore has not
    carried its burden to demonstrate that the commission's decision
    was not supported by substantial evidence.
    The town raises one more specific issue that we must
    address.   It argues that the commission unlawfully substituted
    its judgment for that of Price, who concluded that Alston could
    return to work if he met several conditions.     The town argues
    that agencies are permitted only to "take notice of general,
    technical or scientific facts within their specialized
    46
    knowledge."    G. L. c. 30A, § 11 (5).   As the fact finder,
    however, the commission was free to credit portions of Price's
    expert opinion and disregard others.     Police Dep't of Boston v.
    Kavaleski, 
    463 Mass. 680
    , 694 (2012), quoting School Comm. of
    Brockton v. Massachusetts Comm'n Against Discrimination, 
    423 Mass. 7
    , 15 (1996) ("The commission . . .     is the sole judge of
    the credibility and weight of the evidence before it").        See
    also Boston Police Dep't, 483 Mass. at 474 & n.24 (court defers
    to commission's credibility determinations and factual findings,
    including assessment of expert evidence).
    Moreover, it was appropriate for the commission to reject
    portions of Price's report because it found that she was not
    aware of, or did not incorporate into her report, several
    important considerations that were presented to the board during
    the evidentiary hearing.    See Kavaleski, 463 Mass. at 694 ("The
    commission was entitled to discredit [an expert's] assessment of
    Kavaleski even though Kavaleski offered no expert testimony of
    her own. . . .    The commission properly explained on the record
    its reasons for rejecting portions of [the expert's]
    testimony").     Specifically, the commission found that Price was
    not aware of the following additional information:     the town's
    failure to comprehend the seriousness of Pender's use of "n----
    r" and failure to take the necessary steps to repair the damage
    caused by Pender; the town's enabling of retaliatory behavior
    47
    against Alston by Pender and others and allowing Pender to paint
    himself as the victim; and the town's attacks on Alston's
    credibility "that appeared to lack bona fides and proper regard
    for fundamental fairness and good faith."    The commission
    juxtaposed the extensive record it compiled over the course of a
    ten-day hearing with the more limited and mostly documentary
    information provided to Price by the town.24   The commission also
    offered detailed support based on its findings justifying each
    of these conclusions and explaining its deviation from Price's
    conclusions.   There was therefore no error in the board's
    decision to diverge from Price's conclusion that Alston could
    return to work if several conditions were met.
    c.   Remedy.   All that remains is determining the proper
    remedy for Alston's improper termination.    The statute is
    unequivocal:   G. L. c. 31, § 43, states, "If the commission by a
    preponderance of the evidence determines that there was just
    cause for an action taken against such person it shall affirm
    the action of the appointing authority, otherwise it shall
    reverse such action and the person concerned shall be returned
    to his position without loss of compensation or other rights
    . . ." (emphasis added).    See Malloch, 472 Mass. at 788, quoting
    24 For example, the 2016 hearings at which Pender's
    promotion was considered and to which the commission pointed
    numerous times occurred well over one year after Price evaluated
    Alston.
    48
    Thurdin v. SEI Boston, LLC, 
    452 Mass. 436
    , 444 (2008) ("where
    the language of a statute is plain and unambiguous, it is
    conclusive as to legislative intent").    This express and
    specific language is controlling.    Therefore, we conclude that
    once the commission concluded that the town lacked just cause to
    terminate Alston, the commission was statutorily required to
    order Alston's reinstatement.
    The town argues nonetheless that an order to reinstate an
    unfit firefighter to the payroll and roster without a
    requirement that he actually work is beyond the commission's
    jurisdiction, as it is essentially an order for the town to pay
    for leave for an indefinite time.    The problem with the town's
    argument is that the town has been found responsible by the
    commission for Alston's unfitness.    The town cannot render him
    unfit, and then refuse to rehire or pay him.25
    25We recognize that G. L. c. 151B includes a variety of
    remedies for discrimination, providing for a more flexible
    response to discrimination in the work force. This helps
    explain why G. L. c. 151B provides the exclusive remedy when
    there is a pending claim of discrimination or a decision on the
    merits on the discrimination claim. Ordering Alston to return
    to a work environment in which he cannot currently work is far
    from ideal. Nevertheless, reinstatement is the remedy dictated
    by the civil service law. We do note that the commission
    suggests in its briefing that the town may have the option of
    pursuing involuntary disability retirement on behalf of Alston
    under G. L. c. 32, § 16. Our holding, however, is simply that
    the civil service law requires Alston's reinstatement, and we
    express no opinion as to what options the town or Alston may
    have going forward.
    49
    4.   Conclusion.   For the foregoing reasons, the judgment
    affirming the decision of the Civil Service Commission is
    affirmed.
    So ordered.
