Thousands of United Airlines employees who received religious exemptions from the company's 2021 COVID-19 vaccine mandate but were then forced onto unpaid leave can now pursue their discrimination claims together, after a federal appeals court rejected the airline's bid to dismantle the class action structure.
The ruling exposes how major corporations handled religious objections during the mandate era, shifting leverage toward workers who faced financial penalties despite documented accommodations.
The 5th U.S. Circuit Court of Appeals issued its decision on March 9, 2026, affirming a 2024 district court order that certified a class of customer-facing employees—primarily pilots, flight attendants, and others in direct public roles—who were granted religious accommodations under Title VII but placed on indefinite unpaid leave rather than allowed to continue working with alternatives like masking or testing.
United had argued that individual inquiries into each employee's religious sincerity and the airline's claimed undue hardship would make class treatment impossible. The appeals court disagreed, finding no abuse of discretion in the lower court's certification and emphasizing that common questions about the reasonableness of unpaid leave as an accommodation predominate.
United's Mandate and the Accommodation Gap
United became one of the first major U.S. corporations to impose a broad COVID-19 vaccine requirement in August 2021, mandating compliance or exemption requests within weeks. Of the 5,885 employees who sought religious accommodations, the airline approved 4,070. Yet for customer-facing roles, approval did not mean continued employment. Those workers were sidelined on unpaid personal leave, losing income and benefits while non-customer-facing exempted employees could remain on the job with masking and testing protocols.
Plaintiffs contended that unpaid leave was not a reasonable accommodation under Title VII, which requires employers to explore alternatives unless they impose a substantial burden. The 5th Circuit panel agreed that the policy's application to this group raised shared legal issues suitable for class resolution, including whether United adequately considered less restrictive options before defaulting to unpaid leave.
The Class Narrowed but Survived
The original suit included multiple employee groups: those already on unpaid leave after approved exemptions, those at risk of being placed on leave or terminated, and those allowed to work only under masking/testing conditions. The district court in Texas denied class certification for the latter two subgroups, citing highly individualized circumstances, particularly for medical (ADA) claims. The 5th Circuit upheld those denials but preserved the unpaid-leave religious class—centered on roughly 2,221 core members—for trial.
This outcome keeps one of the highest-profile private-sector challenges to corporate vaccine policies alive. A plaintiff victory could set precedent for how employers balance operational needs against religious protections when alternatives exist short of income loss.
The case now returns to the Northern District of Texas for discovery and a jury trial on the merits. United has not been found liable; the ruling addresses procedural certification only.
Broader Implications for Corporate Mandates
The decision arrives years after most COVID mandates ended, yet it underscores unresolved tensions between employer authority and religious liberty in workplace policy. Similar suits against other companies have gained traction in recent years when exemptions were granted but followed by punitive measures like leave or reassignment.
