    Mark Mason,
    Plaintiff-Appellant,
    v.
    Southern Illinois University at Carbondale,
    Defendant-Appellee.
    Appeal from the United States District Court
    for the Southern District of Illinois.
    No. 96 C 4135--James L. Foreman, Judge.
    Argued February 25, 2000--Decided December 5, 2000
    Before Bauer, Ripple, and Manion, Circuit Judges.
    Manion, Circuit Judge. Mark Mason is a black man
    who worked as a dispatcher (or
    "telecommunicator") for the Department of Public
    Safety (the campus police) at Southern Illinois
    University (SIU). His health problems frequently
    caused him to miss work for substantial periods
    of time, and these absences either caused or
    greatly contributed to his supervisor’s dislike
    of him. Mason thought this dislike was racially
    motivated, so after he was fired, he sued SIU
    under Title VII. A jury found for SIU, and Mason
    appeals, contending that the district court erred
    in excluding evidence of racial epithets that
    some of his coworkers allegedly made when neither
    he nor his supervisor were around. Because the
    district court did not abuse its discretion, we
    affirm.
    I.   Background
    Mark Mason worked as a dispatcher at SIU from
    1983-1998. His health-related absences from work
    (which had always been considerable) increased
    substantially after 1991 when Corporal Carol
    Kammerer, a white woman, became his supervisor.
    One absence lasted nine months, from September,
    1994 to May, 1995. When Mason returned to SIU, he
    worked for about six weeks, took extended sick
    leave again in July, 1995, and never returned to
    work. While on his latest leave, Mason filed a
    worker’s compensation claim against SIU for
    stress; he also unsuccessfully sought other
    employment with SIU. Mason settled this claim in
    the summer of 1998. As part of the settlement,
    SIU offered him his job back, but Mason refused
    this offer. Under the civil service rules, SIU
    had two options at this point--Mason could resign
    or be terminated. Mason refused to resign, so he
    was fired.
    According to Mason, his refusal to return to
    work was due to the rocky relationship he had
    with Kammerer. He claimed she was abusive toward
    him, such as by allegedly calling him "stupid"
    and "dumb" when he would incorrectly perform a
    task. (Kammerer denies referring to Mason ever in
    this fashion.) Even though Kammerer never made
    racist remarks in Mason’s presence, let alone to
    him, Mason believed Kammerer treated him badly
    because he was black and that this treatment
    exacerbated his health problems, which ultimately
    prevented him from working for her. He sued SIU
    under Title VII, claiming racial discrimination
    in the form of a hostile work environment. The
    case proceeded to trial, where the district court
    excluded racial epithets allegedly made by
    Mason’s coworkers which neither Mason nor
    Kammerer ever heard. Mason lost his case before a
    jury and appeals the district court’s evidentiary
    ruling, asking for a new trial. Mason now claims
    that not only his supervisor but also his
    coworkers created the allegedly hostile work
    environment. Because there is a distinction in
    the legal analysis, we first need to resolve this
    dispute.
    A.   Mason’s Title VII Claim
    A close examination of Mason’s complaint
    discloses that he alleged only that his
    supervisor, not his coworkers, was racially
    harassing him. The relevant paragraphs of the
    complaint are as follows:
    21.During the course of his employment with the
    Defendant, the Plaintiff was subjected to
    unwelcome harassment by his supervisor,
    including:
    a. Exposure to stress and harassment
    b. Exposure to racial epithets
    c. Being passed over for promotions and overtime.
    * * *
    24. That the actions of the Plaintiff’s supervisor
    were performed as an agent of the Defendant
    herein and in the course of the supervisor’s
    duties as supervisor.
    (Emphasis added.) Mason never amended this
    complaint to include a claim for coworker-created
    hostile work environment. Nor did he otherwise
    notify SIU that he was complaining of anything
    other than a supervisor-created hostile work
    environment./1
    Even at trial Mason continued to insist that
    Kammerer was the source of his problems. He
    stated that in 1992 he met with the then-newly
    hired head of the Public Safety Department, Sam
    Jordan, to complain that Kammerer was being
    "racist towards me" by "calling me dumb and
    stupid and aggravating me." He later complained
    to Jordan that he had been having "an ongoing
    problem" with Kammerer "harassing me, and I felt
    that she was constantly picking on me because I’m
    black." After years of working underneath
    Kammerer, Mason testified that his health began
    to deteriorate. He felt that working for her "was
    aggravating, humiliating. It was hostile, and I
    wanted to get [out] from under her." He stated
    that while he had experienced some health
    problems before working for Kammerer, his
    symptoms increased substantially once she became
    his supervisor. Mason stated that he had talked
    with "Jordan many times because it appeared to be
    a constant problem that I was having with
    Kammerer." As a result, Mason talked with Jordan
    about getting another job in the department, and
    he made other efforts "to try to get away from
    Corporal Kammerer’s supervision." Mason went on
    disability leave in late 1994 because Kammerer’s
    behavior was harming his health:
    [W]orking at the Department of Public Safety--
    excuse me--working at the Department of Public
    Safety under Corporal Carol Kammerer was causing
    too much problems on my health and no--the
    university wasn’t taking no [sic] actions to
    correct the situation.
    (Emphasis added.) He told the jury that after he
    "had been out of the work environment under
    Carol--under Corporal Kammerer for several
    months," his "condition started to improve." He
    then briefly mentioned that when he returned to
    work in May of 1995, his white coworkers "acted
    isolated towards me," not talking "to me like
    they generally did. Sometimes I would speak to
    them and they wouldn’t even speak back to me."
    Mason said that when he returned to work for the
    last time, Kammerer "started treating me the way
    she normally treated me. Yell at me, scream at
    me, holler at me. [sic]" According to him, as of
    the trial, Kammerer was still "in charge of
    telecommunicators" and he was not "aware of any
    action that’s been taken against her" in response
    to his complaints about her.
    On cross-examination, Mason confirmed that his
    harassment claim was based on Kammerer’s conduct,
    not that of his coworkers or anyone else:
    Q. And you were offered the position you were
    offered your position to return to once you had
    completed [maximum medical improvement as part of
    Mason’s workman’s compensation claim]?
    A. That’s correct.
    Q. And you said you weren’t going to return to the
    telecommunicator’s job at SIU; is that right?
    A. No. I said I do not want to return back to work
    that position working under Corporal Carol
    Kammerer.
    Q. Oh. You would have worked in the radio room,
    but just under another supervisor?
    A. If they would have allowed me.
    Q. So it wasn’t the radio room? It was Kammerer?
    A. Yes.
    (Emphasis added.) Mason twice repeated that
    Kammerer was the cause of his problems./2
    The focus of this testimony regarding
    mistreatment by his supervisor is important
    because a probationary dispatcher named Patty
    Shands worked in the telecommunications division
    for about five months during the spring and
    summer of 1995. She became friends with Mason and
    was called to testify on his behalf regarding her
    observations of the conduct of Kammerer and other
    employees in the division. A key issue at trial
    and on appeal is the extent to which the judge
    limited her testimony.
    B. Shands’ Testimony and Mason’s Offer
    of Proof
    After he testified, Mason called Carol Kammerer
    to the stand who, not surprisingly, denied
    calling Mason "dumb" or "stupid" or using a
    racial epithet to refer to him or any employee.
    She denied ever hearing a subordinate make a
    racially derogatory remark, and stated that she
    would not allow a subordinate to make such a
    remark. Mason attempted to ask Kammerer whether
    she knew that Patty Shands had alleged that a
    white dispatcher had "used the word ’n’ word." At
    this point, SIU moved to bar Shands’ testimony
    concerning actions by coworkers, arguing that it
    was not relevant to the claim of supervisor-based
    harassment that Mason had consistently alleged in
    his pretrial filings and had just laid out in his
    own testimony. The district court concluded that
    Mason was making a claim of a racially hostile
    work environment caused by his supervisor, Carol
    Kammerer. As a result, it would allow Shands to
    testify to anything she heard Kammerer say. And
    in order to allow Mason to show that Kammerer, as
    the racial harasser, was responsible for creating
    the work environment in general, the district
    court would also allow Shands to testify to
    anything that coworkers said in Kammerer’s
    presence (although the court thought even this
    might be crossing the line into irrelevant
    testimony). In other words, while Mason’s claim
    was predicated on Kammerer’s behavior, the court
    would allow Mason to develop a theory in which
    her behavior extended to approving the alleged
    racist conduct of subordinates.
    Shands took the stand and testified that once
    when Kammerer was upset because Mason’s health-
    related absence forced her to re-do the work
    schedule, Kammerer referred to Mason as Jordan’s
    "token nigger" in front of Shands and two
    coworkers. Shands’ testimony then violated the
    court’s order when she stated that after Kammerer
    left the room, one of her two coworkers referred
    to Mason in the same way. SIU objected, and the
    district court instructed the jury to disregard
    this piece of testimony. Shands again went beyond
    the court’s ruling by stating that before
    Kammerer allegedly referred to Mason in that
    derogatory manner, Shands had never heard any of
    her coworkers refer to him that way. Then she
    testified about another time when Kammerer was
    upset at having to alter the work schedule and a
    coworker allegedly referred to Mason as a "token
    nigger" in front of Kammerer; Kammerer did not
    react to (let alone discipline) the coworker for
    doing so. Finally, Shands testified that after
    she became friends with Mason, her coworkers
    "blackballed" her. She also noted that after she
    was fired from the communications division in
    July, she filed a complaint with SIU discussing
    "racial issues" in the Department of Public
    Safety, and she subsequently filed a charge with
    the EEOC claiming that she was fired because she
    was friends with Mason.
    Mason’s counsel made an offer of proof as to
    what Shands’ testimony would have included had
    the court not restricted her. He said that Shands
    would have testified that her coworkers: 1) used
    racial epithets to refer to black people
    generally or to Mr. Mason in particular, and one
    coworker called her a "nigger-lover"; 2) told her
    "not to even mention Mark Mason’s name in front
    of Corporal Kammerer" and that "if she did she
    would have to look for another job"; 3) told her
    that "Kammerer hates Mark Mason," was "sick of
    him and doesn’t like having to work with him";
    and 4) increased their usage of racial epithets
    dramatically after Kammerer used a racial epithet
    to refer to Mason. The district court had
    excluded the proposed testimony because it would
    be confusing to the jury and prejudicial; the
    court was trying "a lawsuit involving Mark Mason
    and SIU, and then we jump the track and we start
    trying Patty Shands’ case." It also thought the
    proposed testimony would be irrelevant: Mason’s
    claim concerned a "hostile work environment
    brought about by a supervisor, and all the
    testimony that you were wanting to bring out and
    have made the offer of proof on does not
    necessarily tie itself to Ms. Kammerer who is the
    supervisor involved." And the court considered
    the testimony to be cumulative because there was
    already substantial evidence showing Kammerer’s
    hostility. Finally, the court seemed to question
    whether Shands’ testimony would be perjurious.
    She had executed an affidavit stating that she
    never heard anyone in the Department of Public
    Safety use a racial term and that she never heard
    anyone in the Department use such a term about
    Mason./3 The jury returned a verdict for SIU.
    Mason now challenges the district court’s
    evidentiary ruling that limited Shands’
    testimony.
    II.   Discussion
    We review the district court’s decision to
    exclude testimony for an abuse of discretion.
    Palmquist v. Selvik, 
    111 F.3d 1332
    , 1339 (7th
    Cir. 1997). An "appellant carries a heavy burden
    in challenging a trial court’s evidentiary
    rulings" because of the "special deference" a
    reviewing court gives them. 
    Id.
     Furthermore, even
    if Mason meets this heavy burden, we do not
    reverse a jury verdict if the error is harmless;
    the error must have affected the party’s
    substantial rights. See Fed. R. Civ. P. 61
    (disregard errors that do not affect "substantial
    rights"); Fed. R. Evid. 103(a) (error must affect
    "a substantial right of a party"); Jones v.
    Lincoln Elec. Co., 
    188 F.3d 709
    , 725 (7th Cir.
    1999) (citing Fed. R. Civ. P. 61 and Fed. R.
    Evid. 103) (reversal is required and a new trial
    is warranted only if error affected a party’s
    substantial rights). The party must also have
    made the substance of the evidence known to the
    court by an offer of proof or otherwise. Fed. R.
    Evid. 103(a); United States v. Cleggett, 
    179 F.3d 1051
    , 1055 (7th Cir. 1999). The offer of proof
    (or the record elsewhere) must show "the grounds
    for admissibility, what the proponent expects to
    prove by the excluded evidence, and the
    significance of the excluded testimony."
    Cleggett, 
    179 F.3d at 1055
    ; see also United
    States v. Vest, 
    116 F.3d 1179
    , 1189 (7th Cir.
    1997).
    The law against discrimination in the workplace
    is well settled. Title VII provides that it
    "shall be an unlawful employment practice for an
    employer . . . to fail or refuse to hire or to
    discharge any individual, or otherwise to
    discriminate against any individual with respect
    to his compensation, terms, conditions, or
    privileges of employment, because of such
    individual’s race . . . ." 42 U.S.C. sec. 2000e-
    2(a)(1). An employer may be liable for
    discrimination within the meaning of Title VII if
    an employee is subject to a hostile work
    environment based on his race. To recover, an
    employee must show that: 1) he was subject to
    unwelcome harassment; 2) the harassment was based
    on his race; 3) the harassment was severe and
    pervasive so as to alter the conditions of the
    employee’s environment and create a hostile or
    abusive working environment; and 4) there is a
    basis for employer liability. See Parkins v.
    Civil Constructors of Ill., Inc., 
    163 F.3d 1027
    ,
    1032 (7th Cir. 1998). The employer is essentially
    strictly liable if the employee’s supervisor
    created the hostile work environment. See
    Burlington Indus., Inc. v. Ellerth, 
    118 S. Ct. 2257
    , 2270 (1998); Faragher v. City of Boca
    Raton, 
    118 S. Ct. 2275
    , 2292-93 (1998)./4 The
    employer is liable for a hostile work environment
    created by the employee’s coworkers, however,
    only when the employee shows that his employer
    has "been negligent either in discovering or
    remedying the harassment." Parkins, 
    163 F.3d at 1032
    .
    A.   Mason’s Claim
    In his reply brief, perhaps recognizing the
    problems with using coworker conduct to prove a
    claim of supervisor harassment, Mason contends
    that he properly presented a claim based on
    coworker harassment in the first place, in
    addition to his claim based on supervisor
    harassment. If so, he now contends that Shands’
    excluded testimony is relevant to proving the
    coworker aspect of his claim. The district
    court’s accurate conclusion that Mason only
    presented a claim for supervisor harassment was
    clearly critical to its evidentiary ruling.
    Because Mason does not dispute this conclusion
    until his reply brief, this new argument is
    waived. See Holman v. Indiana, 
    211 F.3d 399
    , 405
    n. 5 (7th Cir. 2000).
    Assuming this argument were preserved, it is of
    course true, as Mason notes, that Fed. R. Civ. P.
    8(a) only requires a short and plain statement
    that will provide the defendant with fair notice
    of his claim. See Ryan v. Mary Immaculate Queen
    Ctr., 
    188 F.3d 857
    , 860 (7th Cir. 1999). But as
    we have noted, Mason’s complaint does not fairly
    notify SIU that he is claiming coworker
    harassment. Although he attempts to magnify the
    meaning of paragraph twenty-three of his
    complaint,/5 it is not only silent on coworker
    conduct, but it is inextricably sandwiched
    between two paragraphs specifically discussing
    supervisor harassment. Mason might have been able
    to shoehorn a claim for coworker harassment into
    paragraph twenty-three for purposes of surviving
    a motion to dismiss by alleging hypothetical
    facts about harassing coworkers. But even then
    the hypotheticals would have to be consistent
    with his allegations of supervisor harassment.
    See Holman, 
    211 F.3d at 405
    . Aside from the fact
    that he has produced no evidence of his being
    harassed by coworkers, Mason has consistently
    represented that he was claiming supervisor
    harassment. He did so during discovery, and he
    repeatedly testified at trial that this was
    indeed his claim. His one brief comment
    concerning his coworkers-- that while they
    "generally" talked to him, after he returned from
    his nine-month absence "sometimes" they wouldn’t-
    -is hardly sufficient, given the overwhelming
    thrust of his testimony, to place SIU on notice
    that he was (now) claiming an additional type of
    hostile work environment. Certainly by the time a
    plaintiff testifies in his case in chief, a
    defendant is entitled to rely on the notice that
    the complaint has given him when its allegations
    are confirmed by the plaintiff’s own trial
    testimony. See Vidimos, Inc. v. Laser Lab Ltd.,
    
    99 F.3d 217
    , 222 (7th Cir. 1996). To allow Mason
    to introduce evidence of alleged coworker
    harassment via Shands’ testimony would be
    allowing him to amend his complaint to include a
    new claim based on coworker harassment. See
    Chaveriat v. Williams Pipe Line Co., 
    11 F.3d 1420
    , 1428-30 (7th Cir. 1993). At this late stage
    of the case, the district court did not abuse its
    discretion in not allowing Mason to do so. 
    Id. at 1430
     (court does not abuse its discretion when it
    prevents unfair prejudice to defendant from
    admitting evidence that would inject a new claim
    late in the proceedings)./6
    B. Analyzing the Totality of
    Circumstances
    As shown above, this case involves allegations
    of harassment by a supervisor. Yet in his initial
    appellate brief, Mason essentially argues that
    all evidence of harassment is always relevant,
    regardless of the type of claim the plaintiff is
    asserting, and that therefore all of Shands’
    testimony was relevant and admissible. This broad
    assertion is not correct.
    Harassment "by co-workers differs from
    harassment by supervisors." Parkins, 
    163 F.3d at 1032
    . As a result, an "employer’s liability for
    hostile environment sexual harassment depends
    upon whether the harasser is the victim’s
    supervisor or merely a co-employee." 
    Id.
     This
    same distinction applies in a racial harassment
    case when determining employer liability.
    If a plaintiff claims that he is suffering a
    hostile work environment based on the conduct of
    coworkers and supervisors, then under the Supreme
    Court’s totality of circumstances approach,
    Farragher, 118 S. Ct. at 2283 (citing Harris v.
    Forklift Systems, Inc., 
    510 U.S. 17
    , 23 (1993)),
    all instances of harassment by all parties are
    relevant to proving that his environment is
    sufficiently severe or pervasive. See Williams v.
    General Motors Corp., 
    187 F.3d 553
    , 559, 562-63 &
    n.4 (6th Cir. 1999) (plaintiff’s claim was based
    on the behavior of supervisors and coworkers and
    conduct of both types of harassers was relevant);
    Silk v. City of Chicago, 
    194 F.3d 788
    , 803, 806
    (7th Cir. 1999) (assuming there is an ADA hostile
    work environment claim, actions of both coworkers
    and superiors are relevant to determining whether
    environment was severe or pervasive). Courts
    should not carve up the incidents of harassment
    and then separately analyze each incident, by
    itself, to see if each rises to the level of
    being severe or pervasive. Williams, 187 F.3d at
    561-62.
    That does not mean, however, that courts can
    automatically lump into the analysis of the
    behavior by one type of harasser behavior by a
    different type of harasser when the plaintiff is
    not pursuing a claim based on the latter’s
    conduct. Cf. id. at 562 ("District courts are
    required to separate conduct by a supervisor from
    conduct by co-workers in order to apply the
    appropriate standards for employer liability.");
    Parkins, 
    163 F.3d at 1032
     (liability depends on
    whether harassment is by supervisor or
    coworkers). If a plaintiff pursues a hostile work
    environment claim based on the behavior of a
    supervisor, evidence of harassment by a coworker
    logically must be tied somehow to the supervisor
    for it to be relevant and admissible. Otherwise,
    including such evidence could confuse the jury
    and prejudice the defendant. See Fed. R. Evid.
    403./7 Thus, when considering the totality of
    the circumstances the district court here did not
    abuse its discretion when it limited Shands’
    testimony to behavior and comments attributed to
    Kammerer, or to those attributed to coworkers
    while Kammerer was present.
    C. Supervisor Harassment and Shands’ Excluded
    Testimony
    Mason also argues that Shands’ excluded
    testimony is relevant to his claim of a
    supervisor-created hostile work environment to
    show the pervasiveness of the environment or to
    show Kammerer’s "real" motives for her ostensibly
    "race-neutral" treatment of him. In some
    "supervisor" cases, evidence of coworker behavior
    might be relevant to show pervasiveness or
    motive. But Mason did not make these arguments
    until his reply brief, so they are waived. And
    even if he had preserved them, in this case, as
    we shall see, these arguments are re-packaged
    attempts to use incidents of coworker behavior to
    establish a claim that is based on supervisor
    harassment. Furthermore, neither Mason nor
    Kammerer were even present for the alleged
    incidents of coworker harassment that Shands’
    testimony would purportedly expose. Thus, Mason
    is trying to hold SIU strictly liable (by
    nominally proceeding under a claim of supervisor
    harassment) by using evidence of coworker
    harassment of which neither he nor the supervisor
    in question were even aware. Mason cannot
    bootstrap coworker behavior onto his claim of
    supervisor harassment.
    As to pervasiveness, Mason argued to the
    district court that the conduct of his coworkers
    is relevant to some sort of derivative supervisor
    harassment theory under which Kammerer, through
    racist behavior, "sets the tone" of the
    department, signaling to subordinates that it is
    okay if they harass Mason, their coworker. Cf.
    Knox v. Indiana, 
    93 F.3d 1327
    , 1334 (7th Cir.
    1996) (noting possibility of a Title VII
    retaliation theory where a supervisor permits a
    plaintiff’s "fellow employees to punish her for
    invoking her rights under Title VII"). As we
    understand Mason’s theory of "supervisor"
    harassment, the actions of the coworkers are
    deemed to be the actions of the supervisor for
    which the company is then (strictly) liable. This
    appears to be another "bootstrapping" effort, but
    since Mason has failed to pursue this argument on
    appeal, we need not wrestle with it.
    Whatever supervisor-based theory Mason might
    wish to employ to establish pervasiveness, there
    is a clear problem with using Shands’ excluded
    evidence of coworker comments: Mason never knew
    of these comments. Mean-spirited or derogatory
    behavior of which a plaintiff is unaware, and
    thus never experiences, is not "harassment" of
    the plaintiff (severe, pervasive, or other).
    Thus, for alleged incidents of racism to be
    relevant to showing the severity or pervasiveness
    of the plaintiff’s hostile work environment, the
    plaintiff must know of them. See Ngeunjuntr v.
    Metropolitan Life Ins. Co., 
    146 F.3d 464
    , 467
    (7th Cir. 1998) (racial comments made outside
    employee’s presence did not show hostile
    environment); Johnson v. City of Fort Wayne, 
    91 F.3d 922
    , 938 & n.8 (7th Cir. 1996) (harassing
    conduct must be directed at employee in order to
    show racially hostile environment); see also
    Burnett v. Tyco Corp., 
    203 F.3d 980
    , 981 (6th
    Cir. 2000) (hostile actions of which plaintiff
    was unaware were not relevant to her claim of a
    hostile work environment); Carter v. Chrysler
    Corp., 
    173 F.3d 693
    , 701 n.7 (8th Cir. 1999)
    (Plaintiff knew of graffiti "during the time in
    which she experienced harassment. It is thus
    relevant on whether a hostile work environment
    existed . . . ."); cf. Hardin v. S.C. Johnson &
    Son, Inc., 
    167 F.3d 340
    , 347 (7th Cir. 1999)
    (doubting the admissibility "of odious
    statements" plaintiff never heard to show racial
    motive)./8
    Here, it is undisputed that no one ever made
    such comments to Mason or in his presence, and in
    his offer of proof, Mason’s attorney did not
    advise the court that Shands would testify that
    she had ever told Mason about his coworkers’
    alleged use of racial epithets. Nor is it
    otherwise apparent from the record that Shands
    told Mason about them (or that he otherwise knew
    of them)./9 Mason’s offer of proof thus failed
    to advise the district court of how Shands’
    testimony would be of significance in terms of
    establishing pervasiveness. United States v.
    Peak, 
    856 F.2d 825
    , 832 (7th Cir. 1988) ("the
    adequacy of [an offer of proof] is an essential
    prerequisite to a finding of error").
    As we have said, "it is up to the party
    challenging exclusion to formulate an offer which
    satisfies all needs. One of the needs in this
    case was some indication" that, at a minimum,
    Mason was aware of these epithets. United States
    ex rel. Veal v. DeRobertis, 
    693 F.2d 642
    , 648
    (7th Cir. 1982); see also United States v. King,
    
    75 F.3d 1217
    , 1223 (7th Cir. 1996) (requiring
    specificity in offer of proof and rejecting
    "blanket" offers). Mason acknowledged at oral
    argument that his "counsel had an opportunity to
    make a full and complete offer of proof." United
    States v. Schroeder, 
    902 F.2d 1469
    , 1471 (10th
    Cir. 1990). There is no reason why he could not
    have offered to have Shands prove that she told
    Mason about the racial epithets his coworkers
    allegedly used when he wasn’t around. Because we
    do not know whether Shands was in fact prepared
    to so testify, we cannot assess whether the
    exclusion was "prejudiciously erroneous." See
    Cleggett, 
    179 F.3d at 1055
    ; King, 
    75 F.3d at 1223
    ; United States v. Alden, 
    476 F.2d 378
    , 381
    (7th Cir. 1973).
    Mason also argues that the excluded evidence of
    coworker comments is relevant to show that
    Kammerer’s racially neutral but negative
    treatment of him was based on his race. See
    Carter, 
    173 F.3d at 701
    . More specifically, it
    would show that Kammerer did not put a stop to
    Mason’s coworkers’ alleged racist comments
    because of her own racial animus. We disagree
    with the relevance of such evidence here. The
    district court allowed into evidence anything
    racial that Kammerer allegedly said (even when
    Mason was not around), as well as anything racial
    that coworkers allegedly said in Kammerer’s
    presence (again, even when Mason was not there).
    What Mason seeks to admit to establish Kammerer’s
    motives are statements that coworkers allegedly
    made when she was not there. While evidence of
    coworker behavior of which the supervisor was
    aware might be relevant to show the supervisor’s
    motives, Carter, supra, there has to be proof
    that she was aware of or that she at least had
    some connection to the behavior. Because Kammerer
    was not present on those occasions when coworkers
    allegedly made the comments in question, the
    alleged comments are not relevant to showing her
    motives. Cf. Hunt v. City of Markham, Ill., 
    219 F.3d 649
    , 652 (7th Cir. 2000) ("the fact that
    someone who is not involved in the employment
    decision of which the plaintiff complains
    expressed discriminatory feelings is not evidence
    that the decision[maker] had a discriminatory
    motivation"); Smith v. Leggett Wire Co., 
    220 F.3d 752
    , 759 (6th Cir. 2000). Therefore, the district
    court did not abuse its discretion in excluding
    this evidence.
    D.   Harmless Error
    Assuming it was error to exclude this testimony,
    the exclusion did not deprive Mason of a
    "substantial right" (as required by Fed. R. Civ.
    P. 61 and Fed. R. Evid. 103(a)) in that we do not
    think the outcome would have been different but
    for the excluded testimony. Jones, 
    188 F.3d at 725
    . If Shands had attempted to testify that when
    neither Kammerer nor Mason were around her
    coworkers sometimes used racial epithets, SIU
    would have attempted to impeach her with her
    affidavit in which she swore unequivocally that
    at no time did she ever hear any racial epithets
    at SIU, including ones referring to Mason. As it
    stood, the jury heard Patty Shands’ accounts of
    racial epithets in the Public Safety Department;
    it simply did not believe her. We doubt her
    credibility with the jury would have improved
    much once SIU cross-examined her with her
    unequivocally contrary affidavit.
    Shands’ remaining testimony was about coworkers’
    statements that Kammerer disliked Mason. Mason
    testified to this at great length. Thus, to say
    that this testimony would be cumulative is an
    understatement. The jury was already left with
    this impression; it just didn’t believe that
    racial prejudice caused it. It is unlikely that
    excluding such cumulative evidence would have
    caused the jury to find differently. Palmquist,
    
    111 F.3d at 1341
     (harmless error to exclude
    cumulative evidence); cf. Bankcard America, Inc.
    v. Universal Bancard Systems, Inc., 
    203 F.3d 477
    ,
    482 (7th Cir. 2000) (not plain error to admit
    cumulative evidence).
    III.   Conclusion
    The district court did not abuse its discretion
    in not allowing Mason effectively to amend his
    complaint during the trial to present an
    additional claim for racial harassment based on
    the actions of his coworkers. Furthermore, given
    that Mason presented a claim for harassment based
    on the conduct of his supervisor, the district
    court did not abuse its discretion in not
    admitting evidence of comments that coworkers
    allegedly made when neither Mason nor his
    supervisor were present. Finally, even had the
    court abused its discretion in excluding this
    evidence, the error would have been harmless.
    For the foregoing reasons, then, the judgment of
    the district court in favor of the defendant is
    AFFIRMED.
    /1 For example, in his brief in support of his
    motion to compel, Mason stated that he was
    claiming that Kammerer was subjecting him to a
    hostile work environment. See Plaintiff’s
    Memorandum Supporting His Motion To Compel
    Defendant To Produce Documents at 1 ("Plaintiff
    alleges that Kammerer repeatedly made racially
    harassing comments to him and about him, harassed
    him because of his race, and discriminated
    against him because of his race."); id. at 4
    ("[T]he documents would be crucial for plaintiff
    to be able to prove that Kammerer harassed him
    because of his race."). As a result, the district
    court viewed Mason as claiming a supervisor-
    created hostile work environment. See Memorandum
    And Order (Plaintiff’s Motion to Compel) at 1-2
    ("Mason alleges that Kammerer repeatedly made
    racially harassing comments to him and about him
    and otherwise harassed and discriminated against
    him because of his race."); id. at 2 ("Mason has
    sued under Title VII . . . alleging that . . .
    Carol Kammerer racially harassed him and made
    racially derogatory comments to and about him.").
    /2 For example, Mason testified that:
    A. I believe I said [in writing to SIU’s Director
    of Human Resources] I would like to go back to
    work, but I did not want to go back to work under
    Carol Kammerer. . . . I was expressing the fact
    that I wanted to work. I didn’t want to be off
    work, but I didn’t want to have to work under
    Carol Kammerer and [sic] aggravated, harassed,
    treated unfair--. . . . Being unfair and her
    being racist towards me.
    Q. So if Lieutenant Doan had taken over
    responsibilities for supervising the radio room,
    that would have been fine?
    A. Sure. That would have been fine. The job was
    not the problem. Corporal Kammerer was the
    problem with me.
    (Emphasis added.)
    /3 Specifically, Shands swore in the following
    paragraphs of her affidavit that:
    4. At no time during my employment in the
    Department of Public Safety at Southern Illinois
    University did I personally hear any police
    officer or supervisor in the Department of Public
    Safety make any racially derogatory remark.
    5. At no time during my employment in the
    Department of Public Safety at Southern Illinois
    University did I personally hear any police
    officer or supervisor in the Department of Public
    Safety make any racist remark concerning Mark
    Mason.
    /4 If the employee does not suffer a "tangible
    employment action" as a result of such
    harassment, the employer may raise an affirmative
    defense comprising two elements: "(a) that the
    employer exercised reasonable care to prevent and
    correct promptly [the] harassing behavior, and
    (b) that the plaintiff employee unreasonably
    failed to take advantage of any preventive or
    corrective opportunities provided by the employer
    or to avoid harm otherwise." Ellerth, 
    118 S. Ct. at 2270
    ; Farragher, 118 S. Ct. at 2293. Here, SIU
    has not raised the affirmative defense, and it is
    thus waived.
    /5 "That the harassment had the effect of
    unreasonably interfering with Plaintiff’s work
    performance, and creating an intimidating,
    hostile and offensive work environment that
    seriously affected the psychological well-being
    of the Plaintiff." Complaint, para. 23.
    /6 Mason argues that SIU "was fully aware of
    plaintiff’s claim of coworker harassment" because
    it did not object to a proposed jury instruction
    regarding coworker harassment that Mason had
    drafted and that the parties had submitted as
    part of their joint instructions. This contention
    was also not raised until Mason’s reply brief,
    and to the extent he is contending that this
    submission implies SIU’s agreement under Fed. R.
    Civ. P. 15(b) to amending the pleadings, we
    disagree. See Rosario v. Livaditis, 
    963 F.2d 1013
    , 1022 n.4 (7th Cir. 1992). SIU’s repeated
    objections to Shands’ proposed testimony as not
    relevant to Mason’s claim of supervisor
    harassment belie any notion that SIU tacitly
    consented to Mason bringing in at trial an
    additional claim based on coworker harassment.
    Contrast Whitaker v. T. J. Snow Co., 
    151 F.3d 661
    , 663 (7th Cir. 1998) ("Because both parties
    squarely addressed the strict liability theory in
    their summary judgment briefs, the complaint was
    constructively amended to include that claim.").
    /7 While in Williams, upon which Mason relies, the
    Sixth Circuit recognized that courts must
    separate supervisor and coworker conduct "in
    order to apply the appropriate standards for
    employer liability," 
    id.,
     it stated that it is
    not appropriate to separate the conduct according
    to the type of perpetrator to determine whether
    the harassment is severe or pervasive. See 187
    F.3d at 562 & 563 n.4. Williams is
    distinguishable from this case in that the
    plaintiff there was claiming a hostile work
    environment based on the actions of both
    supervisors and coworkers, see id. at 559,
    whereas Mason has pursued only a supervisor-based
    hostile work environment claim.
    /8 We have stated, however, that with respect to a
    hostile work environment claim that is predicated
    on coworker behavior, the pervasiveness of
    coworker conduct could show the employer’s
    constructive notice of the harassment (presumably
    even if the plaintiff is not present). Wilson v.
    Chrysler Corp., 
    172 F.3d 500
    , 509 (7th Cir.
    1999).
    /9 The only indication in the record that Mason and
    Shands might have discussed their coworkers’
    alleged comments is Mason’s one-word mention
    during his testimony that he and Shands had
    talked about "discrimination." But this solitary
    reference is too cryptic to have apprised the
    district court (or us) that Shands indeed told
    Mason of these statements. And even if Shands
    told Mason about some of these comments, such
    "through the grapevine" or "second-hand" conduct
    is not sufficiently severe or pervasive so as to
    create a hostile work environment. See Savino v.
    C.P. Hall Co., 
    199 F.3d 925
    , 933 (7th Cir. 1999);
    Adusumilli v. City of Chicago, 
    164 F.3d 353
    , 362
    (7th Cir. 1998). And if we further assume that
    Shands did relay these incidents to Mason, we do
    not know how many times she did so; an isolated
    (and in this case second-hand) comment also does
    not create a severe or pervasive environment. See
    Farragher, 118 S. Ct. at 2283-84 ("offhand
    comments . . . will not amount to discriminatory
    changes in the ’terms and conditions’ of
    employment’"); see also Ngeunjuntr, 
    146 F.3d at 467
     (isolated racial comments did not show a
    severe or pervasive environment).
    RIPPLE, Circuit Judge, concurring. In this case,
    an employee seeks to establish a case of racial
    harassment at the hands of a supervisor. In order
    to prove his case before a jury, the employee
    sought to establish that the supervisor made
    racially derogatory remarks about him before
    other employees and that, as a consequence of
    these remarks, there was a perceptible change in
    the manner in which his coworkers treated him.
    The district court admitted all behavior and
    statements of the supervisor and all behavior and
    statements of the coworkers when the supervisor
    was present. It refused to admit, however,
    behavior and statements of the coworkers when the
    supervisor was not present.
    It is important to note what the court does not
    decide. The court does not decide that, as a
    general principle, statements made by coworkers,
    when the supervisor is not present, are
    inadmissible to prove supervisor harassment of a
    worker in violation of Title VII. The court
    recognizes that such coworker statements may be
    relevant in assessing the conduct of the
    supervisor when the circumstances support the
    inference that there is a causal relationship
    between the supervisor’s statements and the
    behavior or statements of the coworkers. In
    acknowledging the relevance of such evidence, the
    court is recognizing the practical realities of
    the workplace. A supervisor ought not escape the
    strictures of Title VII when she sets the stage
    for the harassment of a worker and then simply
    absents herself when the actual harassment takes
    place.
    As my colleagues note, in proving supervisor
    harassment, evidence of coworker behavior can be
    relevant to establish the motive of the
    supervisor. In order to establish the necessary
    link to the supervisor, however, it is necessary
    to show, by direct or circumstantial evidence,
    that the supervisor was aware, or should have
    been aware, that her actions or words would lead
    to the behavior and words of the coworkers. To
    establish a supervisor’s motive through the words
    and actions of the coworkers, it is necessary to
    show that the supervisor should have realized
    that her activity would lead to such a result.
    Here, the employee wished to show that, after the
    supervisor made racially derogatory comments in
    the presence of coworkers, there was a
    substantial increase in racial epithets in the
    coworkers’ parlance and that he was isolated by
    those workers in the daily activities of the
    workplace. My colleagues believe that the
    district court was on solid ground in declining
    to admit the evidence of the coworker’s statement
    because there is no evidence that the supervisor
    was present when the statements were made. It is
    not clear, however, why the supervisor’s presence
    is necessary to establish the relevance of the
    statements to the issue of the supervisor’s
    intent. The defense wanted to establish that, in
    making racially charged statements in front of
    the coworkers, the supervisor was sending a
    signal that treating the plaintiff in a racially
    discriminatory matter was acceptable conduct in
    which the workers could indulge safely without
    fear of reprisal--a message confirmed when a
    coworker did make such a statement before the
    supervisor and incurred no sanction.
    The actions and statements of the coworkers also
    can be relevant, as my colleagues also
    acknowledge, on the issue of whether the
    harassment was pervasive. Here again, the
    employee was entitled to show that the
    supervisor’s statements to the coworkers signaled
    that the supervisor condoned, or even encouraged,
    the racial harassment of the employee.
    My colleagues suggest, however, that the remarks
    of the coworkers are irrelevant on both the
    intent issue and on the pervasiveness issue
    because the employee never knew of the comments.
    The majority is certainly correct in stating that
    mean-spirited or derogatory behavior of which the
    plaintiff is unaware and therefore never
    experiences are not, in themselves, "harassment."
    But, even if these statements were not, in
    themselves, instances of harassment, their
    occurrence can certainly be relevant for the
    limited purposes of showing the intent of the
    supervisor in making the statements and to
    demonstrate that the statements that were heard
    by the employee were the products of an intense
    and concerted effort to set the employee apart
    from his fellow workers on the basis of his race.
    Although the tendered evidence was relevant, the
    decision of the district court not to admit it in
    this case must be sustained. For the reasons
    given by my colleagues, the failure to admit this
    material must be considered harmless error.
    On this basis, I join the judgment of the court.
