    ORDER AND JUDGMENT         *
    Before EBEL , ANDERSON , and MURPHY , Circuit Judges.
    Baker Petrolite Corporation (“Baker”) appeals a judgment entered against it
    following a jury verdict in favor of Appellee, Lewis Turck, in his lawsuit for
    alleged wrongful retaliatory discharge under Oklahoma law. The jury found that
    Turck’s termination was significantly motivated by and in retaliation for his
    attempt to consult his workers’ compensation attorney during his pending
    *
    This order and judgment is not binding precedent, except under the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.
    workers’ compensation action in violation of O        KLA .   S TAT . tit. 85, § 5(A)(2).
    Baker contends that the judgment should be reversed for the following reasons:
    (1) the district court erred in finding that the cause of action upon which Turck
    prevailed was properly pled; (2) the district court abused its discretion by denying
    Baker’s requests for a continuance because Baker needed more time to prepare a
    defense against a claim of which it allegedly had been unaware during discovery;
    (3) the district court abused its discretion by failing to enter a revised pretrial
    order; (4) the district court erred as a matter of law in its interpretation of O           KLA .
    S TAT . tit. 85, § 5(A)(2) and erroneously instructed the jury thereon; (5) the
    district court abused its discretion by excluding evidence of Turck’s past
    behavior, job performance and workers’ compensation claims; (6) the district
    court abused its discretion by admitting the testimony of Turck’s expert witness;
    and (7) the district court erred in denying Baker’s motion for judgment as a matter
    of law because the evidence did not support the jury’s verdict. We exercise
    jurisdiction pursuant to 
    28 U.S.C. § 1291
     and affirm.
    I. BACKGROUND
    Turck worked for Baker and its predecessors for over seventeen years,
    although he apparently was not a model employee. According to Baker, Turck’s
    employment history included the following: Turck was given a verbal warning
    -2-
    for using the company phone for personal calls in April of 1988. Appellant’s
    App. at 561. On July 11, 1988, he was suspended without pay for two weeks for
    insubordination.   
    Id. at 565
    . In January 1989, Turck agreed to work late, but then
    left without permission. As a result of that incident, termination was
    recommended, but did not occur.       
    Id. at 569
    . On December 7, 1989, Turck
    received a warning letter informing him that a female employee had complained
    that he had sexually harassed her and giving him various instructions designed to
    prevent any unnecessary contact between him and the complainant. He violated
    those instructions on January 21, 1990, and was suspended for four days without
    pay. 
    Id. at 627
    . On April 6, 1990, Turck was cited for negligence in performing
    his job duties and warned that further incidents could result in termination.          
    Id. at 570-71
    .
    In August 1990, Turck suffered a work related back injury. He retained
    counsel and filed a workers’ compensation lawsuit on July 20, 1992.             
    Id. at 528
    .
    Despite Turck’s past disciplinary problems, he received a positive performance
    review in 1993. However, his performance review dated September 19, 1994,
    while mostly positive, stated that Turck “needs to improve on his teamwork as
    well as his infectious negative attitude. Lewis needs to build trust and integrity
    with management and to accept management decisions.”            
    Id. at 593
    .
    -3-
    In November 1994, Turck re-injured his back while working on a rail car.
    He retained counsel and filed a second workers’ compensation lawsuit against
    Baker on December 19, 1994.     
    Id. at 542
    . In May 1995, Turck suffered another
    work related back injury. Again represented by counsel, he filed his third
    workers’ compensation lawsuit against Baker on May 25, 1995.        
    Id. at 550
    .
    Turck’s August 15, 1995, performance review rated him “unsatisfactory” in the
    areas of cooperation and attendance and again discussed his negative attitude and
    rude behavior towards other employees, his supervisors and Baker.       
    Id.
     at 598-
    603. Turck was given another review on April 4, 1996, in which he was given
    scores of “unsatisfactory” and “needs improvement” in several categories.         
    Id. at 606-08
    .
    In June 1996, Turck injured his right knee on the job. However, he
    continued to work until July 2, 1996, when Baker sent him home from work
    because it did not think he should be working with the injury. Before he left
    work on July 2, Turck had, as per company policy, filled out his time sheet for the
    next two weeks and turned it in. As a result, he was erroneously paid for days he
    was off work in July. Turck, again represented by counsel, filed his fourth
    workers’ compensation lawsuit against Baker on July 15, 1996, with respect to the
    knee injury. 
    Id. at 559
    . He returned to work on August 28, 1996.
    -4-
    At trial, the parties offered differing accounts of what occurred with regard
    to the overpayment between the time Turck returned to work and December 2,
    1996, and essentially reiterate those positions on appeal. Baker claims that it,
    through human resource manager John Plusquellec, approached Turck about the
    overpayment twice during that period, but that Turck refused to pay it back and
    stated that he wanted to speak with his attorney.    
    Id. at 973-84
    . Turck, on the
    other hand, claims that he attempted to discuss the issue with his immediate
    supervisor, Jimmy Vann, who directed him to Plusquellec after refusing to discuss
    the matter with him.    
    Id. at 731
    . Turck then attempted to speak about the
    overpayment with Jack Cluck, his production superintendent, but Cluck told him
    that he could not discuss the matter because Turck had an attorney.    
    Id. at 824
    .
    Turck alleges that Plusquellec also refused to talk to him about the overpayment
    because he was represented by counsel in his pending workers’ compensation
    action against Baker.    
    Id. at 734
    . Baker points out, and Turck concedes, that
    when he attempted to speak with Plusquellec, he did not use the word
    “overpayment,” but spoke in more general terms about problems with his check,
    pay and disability benefits.   
    Id. at 766-70
    .
    As of December 2, 1996, the overpayment remained outstanding and
    Turck’s workers’ compensation action was pending. Turck received his final
    performance review on that date. It was overwhelmingly negative and warned
    -5-
    that if immediate improvement was not seen, disciplinary action “up to and
    including termination” would be taken.     
    Id. at 613-15
    .
    Later that same day, Turck met with Plusquellec and Vann about the
    overpayment. Turck claims that he told them to take the whole amount out of his
    next check. 
    Id. at 740
    . Plusquellec wanted Turck to sign a payroll deduction
    authorization and presented him with a calculation of the amount owed and the
    time sheet for the period in question. Turck claims that the calculation was
    erroneous. 
    Id. at 741
    . He told the jury that he responded to Plusquellec as
    follows:
    I told him that I also wanted to talk to my work comp attorney before
    I signed anything, that I wasn’t refusing to pay the money back, that I
    wanted to talk to my comp attorney, because I felt that I might
    jeopardize my comp case by signing something, or I felt like that I
    might even be fraudulent by signing something that I could see was
    in error in the time sheet.
    
    Id. at 741-42
    . Vann confirmed that Turck never refused to repay the money but
    did refuse to sign the payroll deduction form without consulting with his attorney.
    
    Id. at 795, 799-800
    . At that point, Plusquellec told Turck to talk to his attorney
    that night so they could meet again in the morning.     Plusquellec never gave Turck
    a copy of the document he was to sign for his attorney to review.    
    Id. at 741, 795
    .
    Turck left work at 7:00 p.m. on December 2, 1996, and was unable to
    contact his attorney that night or the following morning. He reported to work at
    6:45 a.m. the following day. At about 10:00 a.m., he met with Plusquellec, Vann
    -6-
    and Cluck. 
    Id. at 798
    . The meeting of the night before replayed itself with
    Plusquellec demanding repayment and Turck refusing to sign anything until he
    contacted his attorney. At the conclusion of the meeting, Turck was terminated
    by Plusquellec . 1
    Turck commenced this action in Oklahoma state court on November 30,
    1998, and Baker removed the case to federal court in March 1999. In his Petition
    filed in state court, which continued to serve as the complaint following removal,
    Turck made the following allegations:
    8.   On December 2, 1996, Turck was called into the office of
    Baker’s local Human Resource Manager, John Plusquellec, to discuss
    the matter of an overpayment in wages made to Turck approximately
    one year earlier.
    9.   Plusquellec demanded that Turck sign a document
    concerning this overpayment or he would be terminated.
    10. Turck requested that he be allowed to discuss the
    document which he was being requested to sign with his attorney so
    as to insure that he was not jeopardizing his pending worker’s
    compensation action. Turck even offered to have Baker deduct the
    alleged overpayment from his paycheck in lieu of signing the
    proffered document, which request was declined by Baker.
    11. Turck was terminated by Baker on December 3, 1996.
    12. Turck alleges that he was wrongfully termination [sic] by
    Baker in violation of 85 O.S. § 5 solely in retaliation of his having
    filed a workers’ compensation claim against Baker.
    1
    Turck requested that Plusquellec write a letter explaining the reasons for
    termination. In the letter, Plusquellec states, “I have accepted your resignation
    . . . . in response to your refusal to repay the Company for the money owed due to
    overpayment.” Appellant’s App. at 183. However, it is clear from the other
    evidence that Turck was terminated. See, e.g., id. at 637, 800.
    -7-
    Id. at 11.
    After removal, discovery was conducted. Baker deposed Turck on
    August 19, 1999. On December 8, 1999, Baker moved for summary judgment on
    the grounds that Turck had failed to make out a prima facie case under § 5(A)(1).
    In his January 11, 2000, reply to Baker’s motion for summary judgment, Turck
    makes it clear that he is suing Baker under § 5(A)(2),       2
    and that the critical issue
    in this case hinges on “the right of a protected employee to retain counsel.”            Id. at
    136. Baker filed a response to Turck’s reply on January 24, 2000, in which it
    argued that paragraph 12 of the Petition expressly limits Turck to a cause of
    action under § 5(A)(1) and characterized Turck’s § 5(A)(2) argument as an
    “eleventh hour inclusion of a new legal theory [in] an attempt to escape summary
    judgment by creating a sham fact issue.”         Id. at 184. In the event that the court
    2
    O KLA . S TAT . tit. 85, § 5 reads in pertinent part:
    § 5. Discharge of employee–Prohibited grounds
    A. No person, firm, partnership, corporation, or other entity may discharge . . .
    [an employee] because the employee has in good faith:
    1. Filed a [workers’ compensation] claim;
    2. Retained a lawyer for representation regarding a [workers’ compensation]
    claim;
    3. Instituted or caused to be instituted any proceeding under the provisions of
    this title; or
    4. Testified or is about to testify in any proceeding under the provisions of this
    title which relates to the employee’s past or present employment.
    -8-
    decided to allow Turck to proceed on a § 5(A)(2) claim, Baker asked the court to
    re-open discovery so it could address the “new” claim.
    The parties submitted a proposed Pretrial Order on February 8, 2000, which
    was entered on February 9, 2000. The document sets forth Turck’s claim under
    § 5(A)(2), and Baker’s objection to that claim, with its assertion that only a
    § 5(A)(1) claim was at issue.       Id. at 246-69. However, the evidence listed in the
    Pretrial Order, including the testimony of witnesses for both sides, focuses on the
    allegations made in the Petition.      See , e.g. , id. at 255-56.
    On February 24, 2000, the district court held a pretrial conference in which
    it instructed the parties to submit briefs on the issue of whether a § 5(A)(2) claim
    had been properly pled. The court held a final pretrial hearing on March 6, 2000,
    the day of trial, at which it found that the Petition contained factual allegations
    supporting a § 5(A)(2) claim sufficient to give Baker notice of that claim and
    denied Baker’s motion for summary judgment.            Id. at 684-85. At that point,
    Baker reiterated its request for a continuance and a re-opening of discovery. It
    stated that it wanted to depose Turck again, to depose his workers’ compensation
    attorney, and to have time to address the § 5(A)(2) claim by dispositive motion.
    Id. at 689. The district court denied the request.
    Finally, Baker asked the district court to incorporate its proposed
    amendments to the Pretrial Order. The amended version included evidence of
    -9-
    Turck’s performance and behavior problems.       Id. at 440-41. The court, having
    already made it known that it considered those issues to be irrelevant to this case,
    denied Baker’s request to amend the Pretrial Order.    Id. at 695-96.
    Even so, Baker attempted to introduce evidence of Turck’s disciplinary
    problems, poor performance and past workers’ compensation actions at trial. The
    district court excluded that evidence as irrelevant. It also overruled Baker’s
    objection to the testimony of Turck’s expert witness and its objection to the
    court’s interpretation of § 5(A)(2) as found in the jury instructions. After finding
    for Turck, the jury awarded him $111,138 in past lost wages and benefits,
    $108,010 in future lost wages and benefits, and $6000 for mental anguish and
    emotional distress.
    II. DISCUSSION
    A.    Did the District Court Err in Ruling that Turck Properly Pled a
    § 5(A)(2) Claim and in Denying Baker’s Motions to Continue and to
    Amend the Pretrial Order Relating to that Issue?
    As indicated above, Baker contends that the district court erred as a matter
    of law in finding that Turck’s Petition properly pled a § 5(A)(2) claim and in
    allowing the case to be tried on that claim. It asserts that the Petition expressly
    excluded all but a § 5(A)(1) claim, and thus the district court’s decision to allow
    -10-
    the case to go to trial on a § 5(A)(2) claim substantially prejudiced Baker in
    presenting its defense.
    In addition, Baker advances two related and subsidiary arguments. First, it
    argues that the district court erred in denying its motion for a continuance
    because, in order to alleviate the unfair prejudice resulting from the allegedly late
    inclusion of a § 5(A)(2) claim in this lawsuit, it needed additional time to conduct
    discovery and prepare a defense with respect to the “new” claim. Second, Baker
    argues that the district court erred in refusing to amend the Pretrial Order because
    amendment was required so that the Pretrial Order would reflect the alleged
    addition of a § 5(A)(2) claim to the case.
    A complaint must contain “a short and plain statement of the claim showing
    that the pleader is entitled to relief.” F     ED .   R. C IV . P. 8(a)(2). The statement must
    “give the defendant fair notice of what the plaintiff’s claim is and the grounds
    upon which it rests.”     Conley v. Gibson , 
    355 U.S. 41
    , 47 (1957). If the statement
    is sufficient to give the notice required, Rule 8(a)(2) is satisfied and “[i]t is not
    necessary to plead under what particular law the recovery is sought.”             United
    States v. Missouri-Kansas-Texas R.R. Co.              , 
    273 F.2d 474
    , 476 (10th Cir. 1959).
    See also , Hail v. Heyman-Christiansen, Inc.           , 
    536 F.2d 908
    , 909 n.2 (10th Cir.
    1976); Misco Leasing, Inc. v. Keller         , 
    490 F.2d 545
    , 548 (10th Cir. 1974).
    -11-
    Although we have stated that “[a]s a general rule, a plaintiff should not be
    prevented from pursuing a valid clam just because she did not set forth in the
    complaint a theory on which she could recover,” a late shift in the focus of the
    case should not be allowed if it prejudices the other party’s ability to defend the
    action on the merits.   Evans v. McDonald’s Corp. , 
    936 F.2d 1087
    , 1090-91 (10th
    Cir. 1991). Moreover, “the liberalized pleading rules [do not] permit plaintiffs to
    wait until the last minute to ascertain and refine the theories on which they intend
    to build their case.”   
    Id. at 1091
    . Allowing this practice “would waste the parties’
    resources, as well as judicial resources, on discovery aimed at ultimately
    unavailing legal theories and would unfairly surprise defendants, requiring the
    court to grant further time for discovery or continuances.”        
    Id.
     Accordingly,
    although “[a]ll pleadings shall be so construed as to do substantial justice,” F      ED .
    R. C IV . P. 8(f), a complaint must be specific enough to put the defendant on
    notice of the claim(s) against him in order to avoid inefficiency and unfair
    prejudice.
    Factual allegations supporting a claim under § 5(A)(2) are clearly set out in
    the Petition. Taken alone, those allegations would provide adequate notice that a
    § 5(A)(2) claim was at issue. The difficulty, however, arises from the language in
    paragraph 12 of the Petition which states, “Turck alleges that he was wrongfully
    termination [sic] by Baker in violation of 85 O.S. § 5        solely in retaliation of his
    -12-
    having filed a workers’ compensation claim        against Baker.” Appellant’s App. at
    11 (emphasis added). Baker asserts that paragraph 12 expressly limits Turck to a
    § 5(A)(1) claim and that the Petition gives no notice that a § 5(A)(2) claim is
    being raised. After rereading the Petition, the district court stated that Baker’s
    allegation that it had no prior notice of a § 5(A)(2) claim “simply cannot be true”
    because “the circumstances and situation relating to the overpayment and the
    payback of overpayment request stands out here as a fundamental reason . . . or
    motivating factor in the discharge and that does fall within [§ 5(A)(2)] . . . and I
    think it is adequately so pled.”   Id. at 685. We agree.
    As indicated above, the only substantive factual allegations in the Petition
    relate to a § 5(A)(2) claim. A reasonable reading of those allegations should have
    put Baker on notice that Turck was alleging that a substantial motive for his
    termination was retaliation for his insistence on speaking with his workers’
    compensation attorney before signing anything regarding the overpayment.
    Indeed, when Baker’s counsel deposed Turck on August 19, 1999, she asked him,
    “[t]ell me why you were fired because of your workers’ comp injury or because
    you filed a claim or because you saw an attorney with respect to your claim.”     Id.
    at 354. Although his answer was unresponsive, the question reveals that Baker
    was aware that a § 5(A)(2) claim was a possibility given the factual allegations
    made in the Petition, and, more fully, in Turck’s deposition. Finally, Baker does
    -13-
    not dispute the basic facts giving rise to a § 5(A)(2) claim and restates them in the
    “Undisputed Material Facts” section of its motion for summary judgment filed
    December 8, 1999.   Id. at 39-41.
    We have examined the Petition at length and concede that it is poorly
    drafted. However, the issue is not whether the Petition is skillfully drafted, but
    whether it contains a plain statement of Turck’s claims sufficient enough to give
    Baker notice of the claims against which it must defend. We conclude that the
    district court did not commit reversible error by ruling that the factual allegations
    made in the Petition gave Baker notice that Turck was alleging that his refusal to
    sign anything in connection with the wage overpayment until he consulted his
    workers’ compensation attorney was a significant motivating and retaliatory
    factor in his termination in violation of § 5(A)(2).
    That conclusion is dispositive of Baker’s claims of error regarding a
    continuance and its related claims of prejudice. Furthermore, even assuming
    arguendo that Baker did not have notice of the § 5(A)(2) claim until Turck filed
    his response to Baker’s motion for summary judgment, Baker has not
    demonstrated that its ability to defend this action was significantly prejudiced by
    the district court’s actions. This is because: (1) Baker had notice of the
    § 5(A)(2) claim at least by January 11, 2000, nearly two months prior to trial;
    (2) even though discovery was closed at that point, Baker had already questioned
    -14-
    Turck extensively about the events immediately preceding his termination,
    including the demand that he sign a payroll deduction authorization, his refusal to
    do so until he consulted with his workers’ compensation attorney and his
    termination; (3) the events of December 2nd and December 3rd, 1996, were laid
    out for the jury in full through the testimony of Vann, Plusquellec, Cluck and
    Turck; (4) Baker offered a full and competent defense to Turck’s § 5(A)(2) claim,
    and (5) Baker has failed to identify any specific material and admissible evidence
    it would have obtained and presented had the district court granted a continuance
    and re-opened discovery. Baker’s conclusory assertions that it needed to depose
    Turck for a second time and to depose his workers’ compensation attorney lead
    only to pure speculation.
    As stated above, the Pretrial Order definitively states that Turck was
    proceeding under § 5(A)(2) and indicates that the evidence to be presented at trial
    would focus on the allegations made in the Petition. The substantive allegations
    in the Petition support a § 5(A)(2) claim. Thus, the Pretrial Order set forth a
    § 5(A)(2) claim and anticipated that the evidence would focus on that claim.
    Moreover, Baker has failed to show that the Pretrial Order was insufficiently
    definitive or that the district court’s refusal to amend that document worked a
    -15-
    manifest injustice.   3
    See F ED . R. C IV . P. 16(e). Accordingly, we conclude that the
    district court did not err in denying Baker’s request to amend the Pretrial Order.
    B.     Meaning of O       KLA .   S TAT . tit. 85, § 5(A)(2)
    Baker argues that the district court erred as a matter of law in its
    interpretation of § 5(A)(2) and that the court further erred when it instructed the
    jury in accordance with its misinterpretation. We review the district court’s
    determination of § 5(A)(2) de novo.           Salve Regina Coll. v. Russell   , 
    499 U.S. 225
    ,
    231 (1991).   “We review the district court’s decision to give a particular jury
    instruction for abuse of discretion and consider the instructions as a whole de
    novo to determine whether they accurately informed the jury of the governing
    law.” United States v. McClatchey          , 
    217 F.3d 823
    , 834 (10th Cir. 2000)
    (quotation omitted).
    Baker attempts to characterize the district court’s interpretation of
    § 5(A)(2) as follows: “[e]ssentially, the District Court’s interpretation of this
    section, mandates that an employer allow an employee access to an attorney
    before any adverse employment action may be taken. In other words, the District
    3
    A significant feature of Baker’s amended pretrial order was its expansion
    of the scope of evidence to be presented to include Turck’s past behavior and
    performance problems. Appellant’s App. at 440-41. The district court ruled that
    such evidence was irrelevant to Baker’s stated reason for Turck’s termination.  As
    discussed below, those rulings were not erroneous.
    -16-
    Court’s interpretation of the statute creates a civil “Miranda” right for employees
    facing discharge or other adverse action.” Appellant’s Principal Br. at 38-39. All
    of the arguments raised in Baker’s briefs on this issue are devoted to proving that
    § 5(A)(2) “does not provide an employee a right to counsel before an adverse
    employment action may be taken with regard to an employee.” Appellant’s Reply
    Br. at 14 n. 4. However, a fair reading of the district court’s instructions on
    § 5(A)(2) does not support Baker’s characterization.
    The district court’s interpretation of an employee’s rights under § 5(A)(2)
    is best stated in the jury instructions: “You are advised that the term ‘right to
    counsel for representation’ concerning a workers’ compensation claim as stated in
    the Oklahoma Workers’ Compensation Act includes the right to reasonable access
    to and advice from such retained counsel regarding any matter relating to a
    workers’ compensation claim.” Appellant’s App. at 486.
    The district court’s interpretation speaks for itself and clearly states that
    § 5(A)(2) grants employees the right to consult with their workers’ compensation
    attorney about a workers’ compensation claim without being terminated in
    retaliation therefor. Although Baker appears to find this interpretation palatable,    4
    Baker seems to approve of the district court’s interpretation as we
    4
    understand it. In its reply brief, Baker states that it “has never asserted that an
    employee could be lawfully discharged if he tried to consult with his workers’
    compensation attorney.” Appellant’s Reply Br. at 14 n.4.
    -17-
    we must review the matter to ensure that the district court correctly construed the
    statute. 5
    We start with the statute itself. It prohibits an employer from terminating
    an employee in retaliation for “[r]etain[ing] a lawyer for representation regarding
    a [workers’ compensation] claim.” O        KLA .   S TAT . tit. 85, § 5(A)(2). A literal
    reading of the statute could support an interpretation that it only protects
    employees from retaliatory discharge when they retain an attorney, but not when
    they consult with that attorney about their workers’ compensation claim.
    However, because the Oklahoma Workers’ Compensation Act is remedial in
    nature, “it should be accorded liberal construction in favor of those entitled to its
    benefits.” Upton v. State of Oklahoma ex rel. Dep’t of Corr.           , 
    9 P.3d 84
    , 88
    (Okla. 2000). An example of the Oklahoma courts’ liberal interpretation of § 5 is
    found in Buckner v. Gen. Motors Corp.        , 
    760 P.2d 803
     (Okla. 1988). In       Buckner ,
    the employee was injured on the job and seen by a company doctor on site and
    placed on limited duty. A few days after the first visit, she had pain from the
    injury again and sought to see the same company doctor about it. While she was
    waiting to see the doctor, she was fired for loitering.        
    Id. at 805
    . At issue was
    Section 5(A)(2) has not been interpreted by the Oklahoma courts. At oral
    5
    argument, we asked the parties whether it would be proper or necessary, in their
    opinion, to certify a question on its meaning to the Oklahoma Supreme Court.
    Both stated that certification was not necessary.
    -18-
    whether she had, at that point, “instituted proceedings” within the meaning of
    O KLA . S TAT . tit. 85, § 5(A)(3).    6
    The Oklahoma Supreme Court held that she had,
    stating, “the provision of medical treatment by the employer, when accompanied
    by circumstances . . . which would lead a reasonable employer to infer that a
    workers compensation claim would in all probability ensue, constitutes the
    institution of proceedings.”      Buckner , 760 P.2d at 811.
    The liberal interpretation of the phrase “institution of proceedings” in
    Buckner supports the district court’s interpretation of the phrase “retain a lawyer”
    in this case. After reviewing         Buckner and other Oklahoma cases in which § 5 is
    construed, and keeping in mind that the statute is to be construed liberally in
    favor of employees, we conclude that the district court’s interpretation of
    § 5(A)(2), and the jury instructions on the subject, taken as a whole, were not
    erroneous.
    C.     Evidentiary Rulings Regarding Past Behavior and Workers’
    Compensation Claims
    It is undisputed that Baker’s stated reason for terminating Turck was his
    refusal to repay the overpayment that occurred in July 1996. Appellant’s App. at
    O KLA . S TAT . tit. 85, § 5(A)(3) provides that an employer cannot terminate
    6
    an employee in retaliation for having “[i]nstituted or caused to be instituted any
    proceeding under the provisions of this title.”
    -19-
    120, 637. Throughout this litigation, Baker has attempted to introduce evidence
    of Turck’s past performance and behavior problems and his previous workers’
    compensation claims in order to prove that it had a legitimate, non-retaliatory
    motive for his discharge. The district court refused to allow that evidence on the
    ground that it was irrelevant to the stated reason for discharge. We review the
    district court’s evidentiary rulings for an abuse of discretion, and will not disturb
    them unless we have    “a definite and firm conviction that the lower court made a
    clear error of judgment or exceeded the bounds of permissible choice in the
    circumstances.”   United States v. Curtis , 
    147 F.3d 1200
    , 1217 (10th Cir. 1998)
    (quotation omitted).
    Relevant evidence is “evidence having any tendency to make the existence
    of any fact that is of consequence to the determination of the action more
    probable or less probable than it would be without the evidence.” F    ED .   R. E VID .
    401. We have reviewed the district court’s rulings in light of Baker’s stated
    reason for discharging Turck and conclude that the decision to exclude evidence
    of Turck’s past behavior problems and prior workers’ compensation claims on the
    ground that the proffered evidence was not relevant to the reason given for
    discharge was well within the district court’s discretion.
    -20-
    D.     Admission of Expert Testimony
    At trial, Turck’s counsel called accountant Gary Barnes for the purpose of
    giving expert testimony on Turck’s past and future lost wages resulting from his
    termination by Baker. Following a brief voir dire, Baker’s counsel objected to
    Barnes’ proposed testimony on the grounds that he was not qualified to give an
    opinion as to Turck’s future lost wages and that the basis of his proposed
    testimony was unreliable. The district court overruled those objections. We
    review for an abuse of discretion.   Goebel v. Denver & Rio Grande W.R.R. Co.           ,
    
    215 F.3d 1083
    , 1087 (10th Cir. 2000).
    An expert witness is a person who is qualified “by knowledge, skill,
    experience, training, or education,” and his testimony will be admitted if it will
    assist the trier of fact to understand the evidence or determine a fact in issue.
    F ED . R. E VID . 702. In order to assist the trier of fact, expert testimony must be
    reasonably reliable. Hence, the Supreme Court has charged the district court with
    the responsibility of acting as a gatekeeper to exclude unreliable expert testimony.
    See Kumho Tire Co., Ltd. v. Carmichael     , 
    526 U.S. 137
    , 141 (1999);   Daubert v.
    Merrell Dow Pharm., Inc. , 
    509 U.S. 579
    , 597 (1993). Expert opinions “must be
    based on facts which enable [the expert] to express a reasonably accurate
    conclusion as opposed to conjecture or speculation.”      Gomez v. Martin Marietta
    -21-
    Corp. , 
    50 F.3d 1511
    , 1519 (10th Cir. 1995) (quotation omitted). However,
    “absolute certainty is not required.”     
    Id.
    Barnes stated that he had a bachelor’s degree in accounting, had done
    accounting work since 1972 and had run his own accounting business since 1983.
    Appellant’s App. at 849-51. Barnes also explained that he used salary data given
    to him by Turck. His figures for back pay involved subtracting what Turck would
    have made if still employed by Baker from what he actually earned since his
    termination. Barnes testified that to determine future lost wages, he entered
    Turck’s current and past salary, as well as information regarding overtime,
    bonuses and 401K plans, into a computer program that calculated an amount and
    discounted it to present value. He stated that he did not factor in real wage
    growth in either calculation and that he tried to avoid speculation by simply using
    figures that were true at the time.     Id. at 886-87. Finally, Barnes acknowledged
    that if Turck received overtime or raises at his new job, his calculation of future
    lost wages would be too high.     7
    In short, the district court had before it sufficient information to determine
    whether Barnes was qualified to perform the calculations necessary to form an
    opinion and testify with regard to Turck’s lost wages and to decide whether the
    7
    The jury apparently weighed Barnes’ testimony in light of the potential
    uncertainty of the figures. It awarded Turck a total of $219,148 in lost wages
    even though Barnes had estimated Turck’s lost wages to be $344,236.
    -22-
    basis for that opinion and testimony was reliable. Based on our review of that
    information under the foregoing legal authorities, we conclude that the district
    court did not abuse its discretion by permitting Barnes to testify.
    E.     Judgment as a Matter of Law
    After the jury verdict, Baker moved for judgment as a matter of law. The
    district court denied the motion. Baker argues that the district court erred in
    denying its motion because the evidence does not support the jury verdict. We
    review de novo.    Baty v. Willamette Indus., Inc.   , 
    172 F.3d 1232
    , 1241 (10th Cir.
    1999). However, we will reverse “only if the evidence points but one way and is
    susceptible to no reasonable inferences supporting the party opposing the
    motion.” 
    Id.
     (quotation omitted). Moreover, “[w]e do not weigh the evidence,
    pass on the credibility of the witnesses, or substitute our conclusions for [those]
    of the jury.”   
    Id.
     Finally, we view the evidence and any reasonable inferences to
    be drawn therefrom in the light most favorable to Turck.      
    Id.
    By way of summarizing and restating the facts set out above, the evidence
    and the inferences that the jury could reasonably draw therefrom, showed that:
    (1) On December 2, 1996, Baker requested that Turck sign a payroll deduction
    authorization so that it could recover the overpayment from his paychecks;
    (2) Turck believed the amount of the overpayment as calculated by Baker was
    -23-
    erroneous and feared that authorizing the repayment might prejudice his pending
    workers’ compensation claim; (3) as a result of the foregoing concerns, Turck
    refused to sign the form without consulting his workers’ compensation attorney;
    (4) Turck was unable to contact his attorney between 7:00 p.m., the time at which
    his shift ended on December 2, 1996, and 6:45 a.m. the following day when his
    December 3, 1996, shift began; (5) on December 3, 1996, Baker again demanded
    that Turck sign the payroll deduction authorization and Turck again refused to do
    so until he was able to consult his workers’ compensation attorney; and (6) Baker
    then terminated Turck. This evidence was sufficient to support the jury’s verdict.
    Accordingly, the district court did not err in denying Baker’s motion for judgment
    as a matter of law.
    III. CONCLUSION
    For the reasons stated above, we AFFIRM the judgment against Baker.
