Decision: Groff v. DeJoy, 600 U.S. 447 (2023).

Groff resets the practical inquiry for evaluating an employer’s claimed hardship from accommodating an employee’s religious practice.

The scheduling record explains the coworker issue

Gerald Groff moved to a seven-employee postal station that initially had no Sunday deliveries. When that changed, his Sunday assignments were covered by other staff or redistributed through a regional hub. Coworkers complained, and one filed a grievance involving contractual rights. Those facts created a question about actual operations—not an assumption that any resentment defeated his request. Groff, slip op. at 2–4.

A complaint about coworkers is not the end of the test

Title VII directs the hardship inquiry to the conduct of the employer’s business. The Court explained that coworker effects count only to the extent they affect that business. A review therefore must connect the claimed extra assignment, shortage, or disruption to what operations actually required. Naming morale or inconvenience does not itself complete that logical step. The substantial-cost standard still depends on the particular business. Groff, slip op. at 18–20.

Religious hostility cannot become the defense

The Court excluded hardship attributable to animosity toward a particular religion, religion generally, or the very idea of accommodating religious practice. Separate a statement objecting to a worker’s faith from evidence about coverage or contractual obligations. If a communication contains both, preserve its full wording and identify each claimed operational consequence rather than treating the entire objection as automatically valid or irrelevant. Groff, slip op. at 19–20.

The Court did not decide that USPS proved hardship

The Third Circuit had treated effects on coworkers, workflow, and morale under the wrong de minimis threshold. The Supreme Court vacated and remanded without deciding that USPS would ultimately lose. For a dispute centered on coworkers, the useful record joins schedules, actual reassignment, stated objections, available coverage, and the reason each alternative was accepted or rejected. The companion remand analysis explains the separate questions about alternatives and the legal standard. Groff, slip op. at 3–4 & 21.

Key takeaways

• Connect a claimed coworker effect to actual business operations.
• Separate staffing or contractual concerns from hostility to religion.
• Keep the full schedule and communication record, including contrary facts.
• Do not describe the remand as a final finding for either side.
