49 F.4th 1331
10th Cir.2022Background:
- Jeannie Parker, a United Airlines reservation agent, took FMLA leave for a vision disorder and to care for her terminally ill father; months later her supervisor accused her of "call avoidance."
- Supervisor played three recorded calls at a meeting, Parker admitted some fault; United suspended her and the supervisor recommended termination.
- United policy required an Investigative Review Meeting (IRM) with an independent manager, Parker, the supervisor, and a union rep; the IRM manager fired Parker after hearing presentations.
- Parker filed a grievance; a senior manager conducted an appellate review by conference call (Parker did not attend), the union rep conceded misconduct under extreme duress, and the senior manager upheld the firing.
- Parker sued under the FMLA alleging retaliatory discharge via a cat’s paw theory; the district court granted summary judgment for United and Parker appealed.
Issues:
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether a supervisor's alleged retaliatory motive can be imputed to United under the cat’s paw theory | Parker: supervisor's bias proximately caused termination despite employer procedures; Staub governs and English should not foreclose recovery | United: independent IRM and appellate reviewers conducted their own investigations, breaking the causal chain | Court: No liability — independent decisionmakers who conducted their own investigations broke the causal chain; cat’s paw not established |
| Whether Parker’s opportunity to rebut the supervisor’s evidence defeats reliance on independent-investigation defense | Parker: mere opportunity to respond (per English) is insufficient after Staub | United: independence of investigators, not mere opportunity to respond, is dispositive | Court: Opportunity to respond alone is insufficient; what matters is whether investigators independently verified the facts — here they did |
| Whether a post‑termination appellate review (85 days later) can break the causal chain | Parker: the delay makes the appellate review irrelevant or prejudicial | United: a reviewer authorized to reverse the firing can break the causal chain even after termination | Court: Post‑termination independent review can break the causal chain; Parker alleged no prejudice from the delay, so the review sufficed to break causation |
| Whether certain exhibits should remain sealed on appeal | Parker (per United’s preference): seal proprietary exhibits | United: seeks continued sealing of specified exhibits | Court: Granted in part — ordered specified exhibits filed under seal |
