Uncorroborated and Inconsistent Evidence Cannot Establish Pretext in FMLA Interference/Retaliation Claims

Case: Richard Thistlethwaite v. Pace Air Freight, Inc.
Court: Court of Appeals for the Sixth Circuit
Date: 2026-05-28
Publication: Not Recommended for Publication (persuasive, not binding precedent)

1. Introduction

Richard Thistlethwaite, a long-tenured employee who rose to director of operations at Pace Air Freight, Inc., alleged that Pace interfered with and retaliated against his rights under the Family and Medical Leave Act (FMLA) when it terminated him days before his return from a February 2021 medical leave. Pace asserted two non-FMLA reasons for termination: (1) Thistlethwaite’s failure to provide management “access to the security camera video records” at terminals he oversaw, and (2) falsification of mileage reports for trips between the Cincinnati and Louisville terminals.

The core appellate issue was narrow and dispositive: even assuming a prima facie case of FMLA interference and retaliation, did the record contain evidence from which a reasonable jury could find Pace’s stated reasons were pretextual?

2. Summary of the Opinion

The Sixth Circuit affirmed summary judgment for Pace. Applying the McDonnell Douglas framework (used when claims rely on circumstantial evidence), the court—like the district court—skipped to the pretext stage and held there was no genuine dispute of material fact that Pace’s explanations were pretextual. The record showed:

  • Thistlethwaite did not provide camera passwords; his shifting and vague explanations did not create a triable issue that Pace’s reason lacked a factual basis.
  • His “innocent explanation” for mileage discrepancies was uncorroborated and insufficiently specific to create a jury question.
  • Pace’s mileage investigation began in late December 2020 or early January 2021—before Thistlethwaite requested February 2021 leave—undercutting a causal inference of FMLA animus.
  • Additional asserted indicia of animus (investigation methods, a comparator employee, and an owner’s 2018 statement) did not support pretext on this record.

3. Analysis

A. Precedents Cited

1) Summary judgment standards and appellate review

  • Seeger v. Cincinnati Bell Tel. Co., LLC, 681 F.3d 274 (6th Cir. 2012)
    Cited for de novo review of summary judgment. The court framed its task as independently assessing whether the record permits a reasonable jury to find for the nonmovant on material facts.
  • Jackson v. VHS Detroit Receiving Hosp., Inc., 814 F.3d 769 (6th Cir. 2016)
    Used to define a “genuine” dispute: one where a reasonable jury could return a verdict for the plaintiff on the evidence presented.
  • King v. Steward Trumbull Mem'l Hosp., Inc., 30 F.4th 551 (6th Cir. 2022)
    Supports construing evidence and drawing reasonable inferences in favor of the nonmovant, while still requiring more than speculation or internally inconsistent assertions to survive summary judgment.

2) The burden-shifting framework for FMLA claims based on circumstantial evidence

  • McDonnell Douglas Corp. v. Green, 411 U.S. 792 (1973)
    Provides the three-step structure: prima facie case, employer’s legitimate reason, and plaintiff’s showing of pretext. The court emphasized that where pretext is dispositive, it may be efficient to proceed directly to that step (especially when the employer has clearly articulated legitimate reasons).
  • Donald v. Sybra, Inc., 667 F.3d 757 (6th Cir. 2012)
    Applied to confirm that both FMLA interference and retaliation claims relying on circumstantial proof can proceed through McDonnell Douglas, and to articulate the burden allocation at each stage.

3) The meaning of “pretext” and what evidence suffices

  • Chen v. Dow Chem. Co., 580 F.3d 394 (6th Cir. 2009)
    Supplies the governing pretext formulations: a plaintiff may show the proffered reason has “no basis in fact,” did not actually motivate the action, or was insufficient to motivate the action. The opinion’s “commonsense inquiry” framing—“for the stated reason or not?”—drove the court’s evaluation of whether Thistlethwaite’s evidence actually undermined Pace’s explanation rather than merely disputing it in the abstract.
  • Moran v. Al Basit LLC, 788 F.3d 201 (6th Cir. 2015)
    Invoked for a practical evidentiary point: although testimony may “lack precision,” it must be “coherent[]” enough to create a fact dispute on its own. The court used this to reject generalized, nonspecific testimony offered to explain away the mileage allegations.

B. Legal Reasoning

1) Why the court “skipped” to pretext

The panel assumed (without deciding) that Thistlethwaite could establish prima facie FMLA interference and retaliation. This maneuver focuses the case on the determinative question: whether the evidence would permit a reasonable jury to conclude that the employer’s reasons are a cover for unlawful FMLA-related motive. This is consistent with Sixth Circuit practice when the employer’s reason is clearly articulated and the plaintiff’s proof of pretext is the weak link.

2) Camera-password rationale: undisputed noncompliance plus inconsistent explanations

Pace’s first reason was straightforward: management asked for security camera access/passwords; Thistlethwaite did not provide them. The court treated the nonproduction as conclusively established and largely undisputed. Thistlethwaite’s effort to show “no basis in fact” rested on the claim that the systems were nonoperational or passwords unavailable/defaulted.

The panel rejected this as insufficient because the record showed:

  • His deposition testimony varied materially (cameras did not work; did not work “100 percent”; Louisville cameras worked but were in wrong locations; Louisville password existed but someone else handled it).
  • Even crediting parts of his account, he did not explain why he could not provide at least the Louisville system password or any partial access information.
  • Documentary snippets (an email referencing replacement of “3” broken cameras and a 2018 installation quote) did not support the broader assertion that all cameras were nonfunctional or inaccessible.

In short, the panel treated the record as failing to generate a reasonable inference that Pace’s password-based rationale was factually baseless or dishonest.

3) Mileage rationale: generalized “innocent explanation” without corroboration or specificity

Pace’s second reason was falsified mileage reports. Thistlethwaite argued he sometimes “followed a truck” to the destination and turned back without entering the terminal, which could explain why employees did not recall seeing him. The panel held this explanation failed to create a jury question because it was:

  • Uncorroborated (no documents, third-party testimony, logs, or other proof).
  • Nonspecific (no clear dates, frequency, or details sufficient to test the claim).

Applying Moran v. Al Basit LLC, the court emphasized that survivable testimony must be coherent enough to support a concrete factual dispute, not merely a theoretical possibility.

4) Timing and causation: investigation began before the leave request

A key retaliation inference often comes from temporal proximity between protected activity (FMLA leave) and adverse action (termination). Here, however, the court highlighted that the mileage investigation began in late December 2020 or early January 2021—before the February 2021 leave request. That sequence undercut the claim that the investigation itself was prompted by FMLA leave and supported the conclusion that Pace’s stated reasons were not a post hoc justification invented after the leave.

5) Other “animus” arguments rejected: investigation methods, comparator, and the 2018 statement

  • Investigation method: Interviewing three employees and relying on their recollection of “memorable” dates was treated as a rational, non-hostile approach, especially given small terminal size and expected employee interaction.
  • Comparator (Joe Voigt): Voigt was investigated for time theft but accusations were “not validated,” whereas Thistlethwaite’s investigation corroborated concerns; thus, the comparator did not show disparate treatment.
  • Owner’s 2018 statement (“f---ed up”): The court accepted Pace’s undisputed explanation that the remark related to alleged insurance fraud during prior leave, not hostility to FMLA leave itself, diminishing its probative value on the 2021 termination motive.

6) Independent sufficient reason

Even if the mileage dispute could be debated, the court noted Pace’s password-based rationale remained an independent ground for termination. That matters because, at the pretext stage, a plaintiff must undermine the employer’s actual reasons in a way that permits a finding that the real reason was unlawful. Where an independent legitimate reason stands unrebutted, the causal chain to FMLA animus is harder to establish.

C. Impact

Although unpublished, the decision reinforces several practical rules likely to influence litigation strategy in FMLA cases within the Sixth Circuit:

  • Pretext requires evidentiary traction: Plaintiffs must do more than offer plausible-sounding alternative explanations; they need record evidence that is specific and internally consistent.
  • Uncorroborated narratives are risky at summary judgment: Especially where the employer offers concrete business reasons, a plaintiff’s vague testimony without dates, frequency, or supporting evidence may be deemed insufficient.
  • Chronology can defeat retaliatory-inference arguments: If an investigation or disciplinary process starts before the protected leave, arguments that it was motivated by that leave weaken substantially.
  • Comparator evidence must be truly comparable: Differences in investigative outcome (“validated” vs. “not validated”) can be enough to defeat an inference of disparate treatment.

4. Complex Concepts Simplified

  • FMLA interference vs. retaliation: “Interference” concerns denying or hindering FMLA rights; “retaliation” concerns punishing an employee for using FMLA rights. This case treated pretext as the central question for both claims because both depended on circumstantial proof of unlawful motive.
  • McDonnell Douglas burden shifting: A legal structure for cases without direct evidence. After a basic showing by the employee, the employer must give a legitimate reason; then the employee must show the reason is a cover (pretext).
  • Pretext: Not merely that the employer was mistaken or harsh, but that the stated reason is not the real reason. Under Chen v. Dow Chem. Co., common pathways are showing the reason is factually false, not the actual motive, or too weak to explain the action.
  • Genuine dispute of material fact: A real, outcome-affecting factual disagreement supported by evidence such that a reasonable jury could rule for the nonmovant. Contradictory or nonspecific assertions may fail to meet this threshold.

5. Conclusion

The Sixth Circuit’s decision underscores that, at the pretext stage of an FMLA interference/retaliation case, a plaintiff must present specific, coherent, and evidentiary-supported facts that cast genuine doubt on the employer’s stated reasons. Here, Thistlethwaite’s inability to meaningfully rebut the camera-password rationale (and his uncorroborated, nonspecific explanation for mileage discrepancies), combined with the investigation’s pre-leave timing, left no triable issue of pretext. The affirmance illustrates the court’s insistence that “commonsense” pretext analysis be grounded in concrete record evidence rather than inference stacked on inconsistent testimony.
