The Eleventh Circuit affirmed a district court's grant of summary judgment in favor of Delta Air Lines against former pilots alleging violations of the Uniformed Services Employment and Reemployment Rights Act. The court held that the pilots' abuse of sick leave provided a legitimate, non-discriminatory reason for their constructive termination and that their compensation was not reasonably certain for pension calculations.

Background

Two former Delta Air Lines pilots, Adam McLean and James Doyle, who also served as reservists in the United States Air Force, sued the airline alleging violations of the Uniformed Services Employment and Reemployment Rights Act. They claimed Delta constructively terminated them due to their military service, underpaid their pension contributions while on military leave, and failed to allow vacation time accrual during long-term military leave. Delta investigated and found that both pilots had abused sick leave and military leave benefits, including working for the military while on paid sick leave and failing to report military orders. Delta notified the pilots of their intent to terminate them for these violations, and both pilots resigned before the termination was finalized. The district court granted summary judgment for Delta on all three claims, finding that the pilots’ abuse of benefits provided legitimate reasons for termination and that the airline’s pension and vacation policies complied with the Act.

The court’s reasoning

The Eleventh Circuit reviewed the case de novo. On the constructive termination claim, the court applied a two-step burden-shifting framework. While the pilots established a prima facie case, the court found that Delta proved by undisputed evidence that it would have terminated the pilots regardless of their military status because they abused sick leave benefits. The court rejected the argument that the concurrent duty policy was discriminatory, noting that the termination was based on sick leave abuse, not military service. On the pension claim, the court held that because the pilots’ compensation was not reasonably certain due to fluctuating hours, Delta was permitted to use the twelve-month average rate, which it did, and was free to contribute more than the statutory minimum. On the vacation claim, the court found that long-term military leave was not comparable to known leaves of absence due to differences in duration, purpose, and the ability to choose when to take the leave.

What it means going forward

The ruling clarifies that employers may terminate employees for abuse of leave benefits even if the employee is in the military, provided the reason is legitimate and non-discriminatory. It also confirms that pension calculations for reservists with fluctuating pay can rely on twelve-month averages when individual rates are not reasonably certain.
