    ____________________________
    ORDER AND JUDGMENT *
    Before TACHA, Chief Judge, SEYMOUR, and BRORBY, Circuit Judges.
    Mr. Heiman worked at United Parcel Service (“United Parcel”) for eighteen
    years, until his termination on December 2, 1998. He sued United Parcel alleging
    the company discriminated and retaliated against him in violation of the
    Americans with Disabilities Act of 1990 (“Disabilities Act”).     1
    42 U.S.C.
    *
    This order and judgment is not binding precedent except under the doctrines of
    law of the case, res judicata and collateral estoppel. The court generally disfavors the
    citation of orders and judgments; nevertheless, an order and judgment may be cited under
    the terms and conditions of 10th Cir. R. 36.3.
    1
    Mr. Heiman also alleged United Parcel retaliated against him in violation of
    Kansas state law. The district court held Mr. Heiman failed to prove a prima facie case of
    retaliation under state law. Mr. Heiman does not appeal, and we do not address, the
    §§ 12101 - 12213. The district court granted summary judgment in favor of
    United Parcel. The court held Mr. Heiman failed to present a       prima facie case
    that he is disabled or suffered retaliation. Mr. Heiman appeals. We have
    jurisdiction pursuant to 
    28 U.S.C. § 1291
     and affirm.
    BACKGROUND
    The material, relevant facts are either undisputed or viewed in the light
    most favorable to Mr. Heiman.     See Simms v. Oklahoma , 
    165 F.3d 1321
    , 1326
    (10th Cir.), cert. denied , 
    528 U.S. 815
     (1999). Mr. Heiman worked for United
    Parcel as a feeder driver, which involved “regular, daily pushing, pulling and
    twisting in order to lift objects, as well as coupling and uncoupling the trailers
    which he hauled over the road on a regular, ongoing basis.” He underwent seven
    surgeries during his employment at United Parcel due to injuries to his back,
    neck, shoulders and knees.
    To alleviate the physically demanding nature of his job, Mr. Heiman asked
    United Parcel to provide him with a Ford power steering tractor, which it did
    except for a few isolated occasions. Ultimately, Mr. Heiman sought a transfer
    district court’s grant of summary judgment for United Parcel on this issue.
    -2-
    from his feeder driver position to a job requiring less physical exertion. United
    Parcel did not transfer him, and Mr. Heiman filed a complaint with the Equal
    Employment Opportunity Commission alleging United Parcel denied him a
    reasonable accommodation. On June 8, 1998, Mr. Heiman filed his complaint in
    district court, after receiving his “right to sue” letter from the commission. On
    October 2, 1998, Mr. Heiman served United Parcel with a copy of the complaint;
    United Parcel filed its answer on October 22, 1998.
    On November 19, 1998, Mr. Heiman had an argument with David Larkin, a
    fellow United Parcel employee. Mr. Larkin subsequently filed a written
    complaint against Mr. Heiman. On November 23, 1998, Mr. Heiman met with his
    supervisors and Union steward to discuss the November 19th incident with Mr.
    Larkin. Initially, Mr. Cantrell, who is Mr. Heiman’s immediate supervisor, told
    him he could continue working at United Parcel pending further investigation, but
    warned him to avoid contact with Mr. Larkin. However, Mr. Heiman became
    frustrated during the meeting and repeatedly asked Mr. Cantrell for a copy of Mr.
    Larkin’s complaint. Mr. Cantrell and the Union steward both asked him to “calm
    down.” After multiple requests, Mr. Cantrell told Mr. Heiman he was too
    confrontational and was being removed from service pending further
    investigation.
    -3-
    On December 2, 1998, Mr. Heiman received United Parcel’s letter
    terminating him. The letter stated in relevant part:
    On November 23, 1998[,] we became aware of a serious
    incident you were involved in on November 19, 1998.
    On November 23, 1998[,] a meeting was held .... At this
    meeting you refused to listen to or follow your manager’s
    instructions. This type of behavior will not be tolerated at United
    Parcel Service. You were taken out of service at that time.
    After a thorough investigation, due to the seriousness of this
    incident, in addition to the serious incident on November 19, 1998,
    you are herein notified your employment with United Parcel Service
    is terminated, effective December 2, 1998.
    Mr. Heiman initially sued United Parcel alleging the company denied him a
    reasonable accommodation, and thereby discriminated against him in violation of
    the Disabilities Act. After his termination, Mr. Heiman amended his complaint to
    allege unlawful retaliation in violation of the Disabilities Act and Kansas state
    law. The district court granted United Parcel summary judgment. The court held
    Mr. Heiman failed to establish a genuine issue of material fact that he qualifies as
    disabled under the Disabilities Act. Specifically, the court concluded Mr.
    Heiman’s evidence, i.e. , a report from a vocational expert, failed to show he was
    substantially limited in the major life activity of working. Moreover, the court
    held Mr. Heiman did not establish a   prima facie case of retaliation because he
    failed to show a causal connection between his protected activity and termination.
    -4-
    Mr. Heiman appeals the district court’s grant of summary judgment.
    “We review the district court's grant of summary judgment de novo,
    applying the same legal standard used by the district court.”     Simms , 
    165 F.3d at 1326
    . Summary judgment is appropriate “if the pleadings, depositions, answers to
    interrogatories, and admissions on file, together with the affidavits, if any, show
    that there is no genuine issue as to any material fact and that the moving party is
    entitled to a judgment as a matter of law.” Fed. R. Civ. P. 56(c). “When applying
    this standard, we view the evidence and draw reasonable inferences therefrom in
    the light most favorable to the nonmoving party.”       Simms , 
    165 F.3d at 1326
    .
    “Summary judgment may be granted if the evidence is merely colorable or is not
    significantly probative.”   Black v. Baker Oil Tools, Inc. , 
    107 F.3d 1457
    , 1460
    (10th Cir. 1997) (quotation marks and citation omitted).
    DISABILITY DISCRIMINATION CLAIM
    We first consider whether Mr. Heiman is a “qualified individual with a
    disability.” Steele v. Thiokol Corp ., ___ F.3d ___, 
    2001 WL 173698
    , at *4 (10th
    Cir. Feb. 22, 2001) (recognizing a showing of disability is a threshold matter for a
    Disabilities Act claim). The Disabilities Act defines an individual with a
    disability as someone who has, in part, “a physical or mental impairment that
    -5-
    substantially limits one or more of the major life activities of such individual.”
    
    42 U.S.C. § 12102
    (2)(A). Pursuant to Equal Employment Opportunity
    Commission regulations, “working” constitutes a major life activity.      See Bolton
    v. Scrivner, Inc. , 
    36 F.3d 939
    , 942 (10th Cir. 1994) (relying on 
    29 C.F.R. § 1630.2
    (i)), cert. denied , 
    513 U.S. 1152
     (1995).
    To demonstrate that an impairment “substantially limits” the major life
    activity of working, an individual must show “significant[] restrict[ion] in the
    ability to perform either a   class of jobs or a broad range of jobs in various classes
    as compared to the average person having      comparable training, skills and
    abilities .” 
    29 C.F.R. § 1630.2
    (j)(3)(i) (emphasis added). “The inability to
    perform a single, particular job does not constitute a substantial limitation in the
    major life activity of working.”    
    Id.
    The following specific factors “should be considered” when determining
    whether an impairment substantially limits a major life activity: “(i) [t]he nature
    and severity of the impairment; (ii) [t]he duration or expected duration of the
    impairment; and (iii) [t]he permanent or long term impact, or the expected
    permanent or long term impact of or resulting from the impairment.” 
    29 C.F.R. § 1630.2
    (j)(2); Bolton , 
    36 F.3d at 943
    . The following additional factors “may be
    -6-
    considered” when determining whether an impairment substantially limits the
    major life activity of working:
    (A) [t]he geographical area to which the individual has reasonable
    access;
    (B) [t]he job from which the individual has been disqualified because
    of an impairment, and the number and types of jobs utilizing similar
    training, knowledge, skills or abilities, within that geographical area,
    from which the individual is also disqualified because of the
    impairment (class of jobs); and/or
    (C) [t]he job from which the individual has been disqualified because
    of an impairment, and the number and types of other jobs not
    utilizing similar training, knowledge, skills or abilities within that
    geographical area, from which the individual is also disqualified
    because of the impairment (broad range of jobs in various classes).
    
    29 C.F.R. § 1630.2
    (j)(3)(ii);   Bolton , 
    36 F.3d at 943-44
     (recognizing the additional
    factors “may be considered,” but holding summary judgment for employer is
    appropriate when the evidence failed to show the employee was restricted from
    performing a class of jobs, or to address the employee’s vocational training and
    accessible geographical area). We apply these factors to the evidence Mr.
    Heiman submitted to avoid summary judgment.
    The only evidence Mr. Heiman offers to overcome summary judgment is
    Mr. Santner’s vocational report which he claims proves he is substantially limited
    in the major life activity of working and creates an issue of fact sufficient to
    -7-
    withstand summary judgment.       2
    Even though the district court never questioned
    Mr. Santner’s qualifications as a vocational expert, Mr. Heiman points out the
    court nevertheless rejected his conclusion Mr. Heiman was substantially impaired
    in the major life activity of working. Specifically, Mr. Santner concluded Mr.
    Heiman “lost the ability to perform approximately 30% of the jobs he might
    normally have been able to access prior to his injuries incurred at [United
    Parcel].” Accordingly, Mr. Heiman claims the district court erred by reasoning
    that a “30% diminution in [his] ability to obtain work in the greater Kansas City
    area was insufficient as a matter of law.”
    Contrary to Mr. Heiman’s contentions, we cannot limit our focus solely on
    Mr. Santner’s expert conclusion that Mr. Heinman suffered a thirty percent
    diminution in job availability. Such a limitation would prevent us from
    evaluating the merits of Mr. Santner’s vocational report in light of the
    abovementioned Equal Employment Opportunity Commission factors.                See
    Bolton , 
    36 F.3d at 943
     (reviewing “the record for evidence of six factors set forth
    in the [Disabilities Act] regulations.”);    see also Broussard v. University of
    California, at Berkeley , 
    192 F.3d 1252
    , 1256-59 (9th Cir. 1999) (reviewing the
    2
    Mr. Heiman does not claim he is substantially limited in any other major life
    activity besides “working.”
    -8-
    merits of the vocational expert’s report to determine whether plaintiff is
    substantially limited in working). Because we believe the whole report must be
    examined on de novo review, we detail the contents of Mr. Santner’s vocational
    report.
    Mr. Santner’s expert report is divided into six sections: (1) records
    received and reviewed; (2) background; (3) work history; (4) medical restrictions;
    (5) procedures; and (6) conclusions.   The labor market statistics are limited to the
    Kansas City, Kansas/Missouri metropolitan area.
    In the “background” section, Mr. Santner acknowledges Mr. Heiman has a
    college degree in art, completed a nine-week police academy course and two
    computer courses, and has a commercial driver’s license. Mr. Santner admits he
    did not consider in his report “professional jobs, typically requiring a college
    degree, since Mr. Heiman has never had a job which required one and, his degree
    in Art would be difficult to use even if it were current.”
    In his “work history” section, Mr. Santner details Mr. Heiman’s
    employment history at United Parcel. Prior to working for United Parcel, Mr.
    Heiman worked as a dump truck and concrete truck driver. Each of these jobs
    -9-
    required Mr. Heiman to lift at least seventy-five pounds. Mr. Heiman also
    worked as a police officer.
    Under “medical restrictions,” Mr. Santner’s report relies on Dr.
    Rondinelli’s March 31, 1998 evaluation of Mr. Heiman. Dr. Rondinelli’s report
    indicates:
    According to the Functional Capacity Evaluation mentioned above
    and previous testing in this regard, I believe Mr. Heiman meets the
    demands of a Feeder with [United Parcel] in regards to weight
    handling requirements, per se. Specifically, he qualifies for
    MEDIUM-HEAVY lifting below shoulder level which would allow
    him to lift loads not to exceed 75 lb on an occasional basis or 50 lb
    on a frequent basis below shoulder level. He qualifies for MEDIUM
    category of lifting at or above shoulder level which would allow him
    to lift weights not exceeding 50 lb occasionally or 25 lb frequently at
    or above shoulder level. He should seek assistance when lifting
    weights exceeding 50 lb at or above should[er] level or 75 lb below
    shoulder level....
    ... Although return to work as a “feeder driver” is not
    medically contraindicated based on the examination and testing
    carried out to date, I believe a prudent and judicious course from this
    point forward would be to reassign him, if at all possible, to a less
    physically demanding job with reduced requirements for materials
    handling.
    (Emphasis in original.) Following this March 3, 1998 evaluation, Mr. Heiman
    continued in his feeder driver position until his termination on December 2, 1998.
    In the “procedures” section of his report, Mr. Santner believes Mr. Heiman
    -10-
    retains “the capability of performing many jobs classified as medium or less,
    however not the entire range of medium jobs or[] jobs classified as heavy to very
    heavy.” In other words, Mr. Santner considers Mr. Heiman, in his post-injury
    state, incapable of performing very heavy, heavy, and some medium classified
    jobs, but able to perform many jobs classified as medium or less. After this
    caveat, Mr. Santner explains he divided the data “into seven separate categories
    of jobs, not including those that would generally be classified as professional in
    nature .... Of the seven classes, Mr. Heiman would be considered to have lost a
    highly significant number of jobs in three of the categories and a significant
    number in one.”
    In his “conclusions,” Mr. Santner suggests Mr. Heiman “lost the ability to
    perform [thirty percent] of the jobs” accessible to him prior to incurring his
    injuries. According to the report, “[e]ighty-five percent of this loss falls into the
    service, processing and miscellaneous categories of employment.” While
    explicitly identifying these three categories, Mr. Santner’s report does not identify
    four of the seven other categories he evaluated, or the total number of jobs Mr.
    Heiman is disqualified from performing due to his injuries. Despite this
    omission, Mr. Santner nevertheless concludes Mr. Heiman’s major life activity of
    working was substantially impaired.
    -11-
    We believe there are several reasons why this expert’s analysis is
    insufficient as a matter of law to show Mr. Heiman is disabled for purposes of the
    Disabilities Act. First, Mr. Heiman presents no evidence establishing his access
    to jobs is limited to the Kansas City metropolitan area, which is the exclusive area
    the expert analyzed.   3
    See Bolton , 
    36 F.3d at 944
    .
    The expert’s report also fails to show the number of jobs Mr. Heiman is
    disqualified from performing due to his injuries.          See Bolton , 
    36 F.3d at 944
    . The
    report identifies only three of the seven job categories considered in Mr.
    Heiman’s vocational assessment: service        4
    , processing 5, and miscellaneous.   6
    Even
    3
    There is evidence in the record suggesting Mr. Heiman lived in Olathe, not
    Kansas City, when United Parcel terminated him. Moreover, he worked in Lexena,
    Kansas for United Parcel.
    4
    The “service” category “includes occupations concerned with performing tasks
    in and around private households, serving individuals in institutions and in commercial
    and other establishments; and protecting the public against crime, fire, accidents and acts
    of war.” United States Dep’t of Labor, Dictionary of Occupational Titles, Ch. 3 (4th ed.
    1991).
    5
    The “processing” category “includes occupations concerned with refining,
    mixing, compounding, chemically treating, heat treating, or similarly working materials
    and products. Knowledge of a process and adherence to formulas or other specifications
    are required to some degree. Vats, stills, ovens, furnaces, mixing machines, crushers,
    grinders, and related equipment or machines are usually involved.” 
    Id.
     at Ch. 5.
    6
    The “miscellaneous” category “includes occupations concerned with
    transportation services; packaging and warehousing; utilities; amusement, recreation and
    motion picture services; mining; graphic arts; and various miscellaneous activities.” 
    Id.
     at
    Ch. 9.
    -12-
    if we assume listing only three of the considered job classes is adequate, the
    expert’s conclusion Mr. Heiman suffered a thirty percent diminution in job
    availability is unhelpful in the abstract.    Cf. Fjellstad v. Pizza Hut of Am., Inc   .,
    
    188 F.3d 944
    , 949 (8th Cir. 1999) (recognizing plaintiff created a factual dispute
    in whether employment opportunities are limited; “there were 28,000 available
    jobs in South Dakota that fit her vocational profile, but ... she is eligible for only
    about 1,300 of these jobs due to her functional limitations”). The mere
    percentage of lost jobs does not identify the number of jobs Mr. Heiman is
    actually disqualified from performing due to his injuries.       See Bolton , 
    36 F.3d at 944
    . It is common sense there is a difference between disqualification from thirty
    percent of ten million jobs versus disqualification from thirty percent of ten jobs.
    Therefore, we hold the expert’s report, which fails to indicate the total number of
    jobs Mr. Heiman is disqualified from as a result of his injuries, does not create a
    genuine issue of fact demonstrating Mr. Heiman is “substantially limited” in his
    major life activity of working.      See 
    29 C.F.R. § 1630.2
    (j)(3)(ii). Such evidence is
    not significantly probative.      See Black, 
    107 F.3d at 1460
    .
    Furthermore, the expert’s report, and ultimately his conclusion, is based on
    an incomplete vocational assessment. The expert disregarded Mr. Heiman’s
    -13-
    college degree when assessing job availability and loss.    7
    See Bolton , 
    36 F.3d at 944
     (recognizing evidence did not address plaintiff’s “vocational training”);       see
    also Heilweil v. Mount Sinai Hosp.     , 
    32 F.3d 718
    , 724 (2d Cir. 1994) (concluding
    plaintiff was not hindered in her ability to work because she possessed advanced
    education degrees),   cert. denied , 
    513 U.S. 1147
     (1995). We do not accept the
    expert’s conclusory dismissal of Mr. Heiman’s college degree because he never
    used the degree, or because the degree was “not current” and would be “difficult
    to use.” Mr. Heiman must be compared to “the average person having
    comparable training, skills and abilities   .” 
    29 C.F.R. § 1630.2
    (j)(3)(i) (emphasis
    added). In this instance, we must compare Mr. Heiman to an average person
    possessing a college degree in art.
    Finally, even though the district court recognized Mr. Santner as a
    vocational “expert,” his “legal” conclusion that Mr. Heiman suffered a substantial
    limitation in his major life activity of working does not create a genuine issue of
    material fact sufficient to withstand summary judgment. “Summary judgment is
    appropriate when an ill-reasoned expert opinion suggests the court adopt an
    7
    Because we view the evidence and draw all reasonable inferences in the light
    most favorable to Mr. Heiman, we assume the expert considered Mr. Heiman’s previous
    education and experience as a police officer when evaluating job availability. See Simms,
    
    165 F.3d at 1326
    .
    -14-
    irrational inference, or rests on an error of fact or law.”      Stearns Airport Equip.
    Co., Inc. v. FMC Corp. , 
    170 F.3d 518
    , 531 n.12 (5th Cir. 1999). As we
    previously discussed, Mr. Santner erred by assuming a thirty percent diminution
    in an unreported number of jobs is, as a matter of law, a substantial limitation.
    Moreover, his conclusion is based on an incomplete vocational profile.
    Therefore, because Mr. Heiman’s evidence fails to establish a genuine issue
    of material fact, we affirm the district court’s determination he is not disabled
    within the meaning of the Disabilities Act.          See 
    42 U.S.C. § 12102
    (2)(A).
    Summary judgment in favor of United Parcel on the disability discrimination
    claim is appropriate.   8
    RETALIATION CLAIM
    8
    Given our holding, Mr. Heiman’s contention the district court erred in
    considering a Tenth Circuit unpublished opinion and not citing additional authority in
    reaching the same conclusion is unpersuasive. We also reject Mr. Heiman’s suggestion
    that this case cannot be disposed on summary judgment because Mr. Santner was never
    afforded the opportunity to provide his details at trial, and United Parcel never elicited
    such details by deposition. A careful review of the record shows discovery was
    completed on July 1, 1999, i.e., five months before the district court granted summary
    judgment. Thus, ample time and opportunity existed to seek, take, or supplement the
    record with Mr. Santner’s deposition. Moreover, we have held “summary judgment need
    not be denied merely to satisfy a litigant’s speculative hope of finding some evidence” to
    rebut the movant’s allegations. Meyer v. Dans un Jardin, S.A., 
    816 F.2d 533
    , 537 (10th
    Cir. 1987) (quotation marks and citation omitted).
    -15-
    Although we hold Mr. Heiman’s underlying disability discrimination claim
    fails, such failure does not prevent him from asserting a Disabilities Act
    retaliation claim.   See Beuttner v. Arch Coal Sales Co. Inc.   , 
    216 F.3d 707
    , 714
    (8th Cir. 2000). The Disabilities Act’s retaliation provision states “[n]o person
    shall discriminate against any individual because such individual has opposed any
    act or practice made unlawful by [the Disabilities Act] or because such individual
    made a charge ... under [the Disabilities Act].” 
    42 U.S.C. § 12203
    (a).
    To establish a prima facie case of retaliation, Mr. Heiman must show: 1)
    he “engaged in a protected activity; 2) [he] was subjected to adverse employment
    action subsequent to or contemporaneous with the protected activity; and 3) a
    causal connection between the protected activity and the adverse employment
    action.” Anderson v. Coors Brewing Co.       , 
    181 F.3d 1171
    , 1178 (10th Cir. 1999).
    United Parcel does not dispute Mr. Heiman satisfied the first two elements of his
    prima facie retaliation claim. We will assume, without deciding, Mr. Heiman
    engaged in two acts of protected activity by filing: 1) an Equal Employment
    Opportunity Commission complaint; and 2) a lawsuit alleging disability
    discrimination. United Parcel also admits Mr. Heiman suffered an adverse
    employment action because he was terminated. Thus, the first two elements of his
    prima facie case are presumed satisified.
    -16-
    Under the third element required to show retaliation, “[a] causal connection
    may be shown by evidence of circumstances that justify an inference of retaliatory
    motive, such as protected conduct closely followed by adverse action.”       O’Neal v.
    Ferguson Constr. Co. , 
    237 F.3d 1248
    , 1253 (10th Cir. 2001) (quotation marks and
    citation omitted). “Unless there is very close temporal proximity between the
    protected activity and the retaliatory conduct, the plaintiff must offer additional
    evidence to establish causation.”     
    Id.
     We have previously “held that a one and
    one-half month period between protected activity and adverse action may, by
    itself, establish causation. By contrast, we have held that a three-month period,
    standing alone, is insufficient to establish causation.”    Anderson , 
    181 F.3d at 1179
     (citations omitted).
    A. Temporal Proximity
    Both parties heavily rely on the temporal proximity between the protected
    activity and the adverse employment action, but they dispute the date the
    protected activity occurred. Mr. Heiman asserts his protected activity occurred on
    October 2, 1998, which is the date United Parcel was       served with the lawsuit
    complaint. Thus, according to Mr. Heiman, only two months accrued between his
    protected activity and termination. In contrast, United Parcel suggests Mr.
    Heiman’s protected activity occurred on or about June 19, 1997, which is the date
    -17-
    United Parcel received Mr. Heiman’s Equal Employment Opportunity
    Commission charge. According to United Parcel, the time lapse was nearly
    eighteen months. We disagree with both contentions.
    Both parties misunderstand what triggers a “protected activity.” Protected
    activity is “the bringing of charges;” it is not     serving an employer with a formal
    lawsuit or receiving an employee’s Equal Employment Opportunity Commission
    complaint. Candelaria v. EG & G Energy Measurements, Inc.            , 
    33 F.3d 1259
    ,
    1262 (10th Cir. 1994);     see also Anderson , 
    181 F.3d at 1178
     (“By    filing an [Equal
    Employment Opportunity Commission] claim, Plaintiff engaged in protected
    activity.”) (emphasis added). We assume, without deciding, the two protected
    activities at issue here occurred when Mr. Heiman “filed” the Equal Employment
    Opportunity Commission complaint and his discrimination lawsuit.           See Amir v.
    St. Louis University,    
    184 F.3d 1017
    , 1025 (8th Cir. 1999) (recognizing plaintiff’s
    protected activity consisted of filing a grievance and a lawsuit against the
    university). Viewing the evidence in the light most favorable to Mr. Heiman, we
    must use the filing date most favorable to him.        See Anderson , 
    181 F.3d at 1179
    .
    In this case, the most favorable filing date is that of Mr. Heiman’s lawsuit, and
    not his Equal Employment Opportunity Commission complaint, which occurred
    -18-
    much earlier.   9
    Mr. Heiman filed his lawsuit in district court on June 8, 1998. Thus, nearly
    six months lapsed between the date of his last protected activity and termination.
    Our cases demonstrate that an intervening period of nearly six months is not
    sufficiently “close temporal proximity” such that an inference of causation is
    warranted based on timing alone. In light of our holding that six months accrued
    between filing his lawsuit and termination, we need not address Mr. Heiman’s
    contention that two months by itself is sufficient to infer a causal connection.
    B. Additional Evidence To Establish Causation
    Having established Mr. Heiman’s protected activity is too remote in time
    from his termination alone to justify an inference of causation, we next examine
    whether Mr. Heiman provided sufficient additional evidence of retaliatory motive.
    See O’Neal , 
    237 F.3d at 1253
    . We hold the evidence presented does not raise an
    inference of causation.   10
    9
    If the filing date for Mr. Heiman’s Equal Employment Opportunity Commission
    complaint is considered, approximately one and one-half years lapsed between that
    protected activity and his termination.
    10
    Because we hold there is insufficient temporal proximity and additional
    evidence to justify an inference of causation, we need not address United Parcel’s
    contention the supervisors who terminated Mr. Heiman lacked knowledge of his protected
    -19-
    Mr. Heiman presents two types of additional evidence: 1) examples of
    other United Parcel employees who raised their voices at their respective
    supervisors, but were not terminated; and 2) alleged “inconsistent statements”
    made by Mr. Heiman’s supervisors. He suggests this evidence “individually
    raise[s] questions of fact concerning the pretextual nature of [United Parcel’s]
    position” and “support[s] a finding of causal connection ... [because] they
    constitute just the sort of ‘other evidence’ which may be considered by this
    court.” In sum, Mr. Heiman presents evidence that goes to the issue of whether
    United Parcel’s proffered reason for his termination is pretextual, rather than
    evidence establishing causation.
    Mr. Heiman, however, misunderstands his initial burden of proofand the
    subsequent burden-shifting that occurs before this pretextual evidence is usually
    considered. A Disabilities Act retaliation claim proceeds under the same burden-
    shifting framework we use for Title VII retaliation claims.        Anderson , 
    181 F.3d at 1178
    . Accordingly, Mr. Heiman first must establish a          prima facie case of
    retaliation. 
    Id.
     Once he establishes a prima facie case, the burden shifts to
    activity. “We will not undertake to decide issues that do not affect the outcome of a
    dispute.” Griffin v. Davies, 
    929 F.2d 550
    , 554 (10th Cir.), cert. denied, 
    502 U.S. 878
    (1991).
    -20-
    United Parcel to “come forward with a non-discriminatory reason for its
    employment decision.”      
    Id.
     If United Parcel presents a non-discriminatory reason,
    the burden shifts back to Mr. Heiman to show “there is a genuine issue of
    material fact as to whether the employer’s proffered reason for the challenged
    action is pretextual, i.e. , unworthy of belief.”   
    Id.
     (quotation marks and citation
    omitted).
    Even if Mr. Heiman understands the nature of his burden at the       prima facie
    stage, he fails to articulate how the pretextual evidence he presents supports an
    inference that filing a lawsuit motivated United Parcel to terminate him.       First,
    Mr. Heiman’s proffered evidence of other United Parcel employees who allegedly
    engaged in misconduct is insufficient because it is not probative of causation
    between Mr. Heiman’s act of filing a lawsuit and his termination. 11 See Black,
    
    107 F.3d at 1460
    .
    The other type of pretextual evidence concerns alleged inconsistent
    11
    Of the evidence that actually identifies a specific employee, it is undisputed two
    of them did not share Mr. Heiman’s same supervisor. See generally Kendrick v. Penske
    Transp. Serv., Inc., 
    220 F.3d 1220
    , 1223 (10th Cir. 2000). In addition, uncontroverted
    deposition testimony shows the two remaining employees did not engage in conduct
    comparable to Mr. Heiman’s.
    -21-
    statements made by his supervisors. However, even if we assume arguendo that
    an employer’s inconsistent reasons for termination can create an inference of
    causation, Mr. Heiman still fails to show United Parcel made inconsistent
    statements. Cf. Farrell v. Planters Lifesavers Co.   , 
    206 F.3d 271
    , 281, 285-86 (3d
    Cir. 2000) (recognizing employee did show, in addition to other evidence, the
    employer’s reasons for termination were inconsistent). Specifically, Mr. Heiman
    argues his supervisors, in deposition, attributed his termination solely to his
    insubordination and failure to follow instructions at the November 23, 1998
    meeting. In contrast, Mr. Heiman notes United Parcel’s termination letter cites
    both the November 23 meeting and the November 19 incident involving his
    argument with Mr. Larkin. In other words, Mr. Heiman contends the fact that
    there were two incidents causing his termination rather than one establishes an
    inconsistency sufficient to justify an inference of causation. We do not agree.
    The two incidents are entirely consistent with each other. United Parcel’s
    reference to the “serious incident” occurring on November 19 supplements, rather
    than contradicts, his supervisors’ reason for firing him. The November 19
    incident merely precipitated the need for the November 23 meeting where Mr.
    Heiman’s insubordination and failure to listen and follow instructions resulted in
    his termination. As the termination letter stated, “[t]his type of behavior will not
    -22-
    be tolerated at United Parcel Service.” Thus, while the termination letter cites
    both the meeting and Larkin incident as contributing to Mr. Heiman’s termination,
    this statement clearly shows Mr. Heiman’s behavior at the November 23 meeting
    is the behavior that ultimately led to his termination. Any perceived
    inconsistency in this evidence does not support an inference of causation.
    Therefore, based on our independent review of the evidence, we hold Mr.
    Heiman fails to establish a   prima facie case of retaliation under the Disabilities
    Act. Neither the six-month lapse between filing a lawsuit and termination alone,
    nor the additional evidence, establish a causal connection. Therefore, summary
    judgment in favor of United Parcel on the retaliation claim is appropriate. Thus,
    “[w]hile the burden [of establishing a Disabilities Act        prima facie case] is ‘not
    onerous,’ it is also not empty or perfunctory.”        Butler v. City of Prairie Village   ,
    
    172 F.3d 736
    , 748 (10th Cir. 1999) (quotation marks and citation omitted). In
    summary, Mr. Heiman fails to establish a          prima facie case of disability
    -23-
    discrimination or retaliation, and we   AFFIRM the district court’s grant of
    summary judgment in favor of United Parcel.
