In a unanimous decision, the U.S. Supreme Court ruled in favor of Gerald Groff, a Pennsylvania postal worker who argued that the U.S. Postal Service violated his religious rights by requiring him to work on Sundays. The ruling represents a major shift in how employers nationwide must handle requests for religious accommodations.

For more than 40 years, companies relied on the 1977 Trans World Airlines v. Hardison ruling, which allowed them to deny religious accommodation requests if they created anything more than a minimal — or “de minimis” — burden. The Court has now declared that this threshold was far too low.

In its 9–0 opinion, the Court held that employers must approve religious accommodations unless they can demonstrate that doing so would cause “substantial increased costs” or an undue hardship on the business. This new, stricter standard significantly elevates the level of protection for employees seeking to practice their faith at work.

Justice Samuel Alito, writing for the Court, emphasized that Title VII of the Civil Rights Act requires employers to meaningfully respect religious observances while maintaining workplace fairness. The ruling brings the standard for religious accommodations more in line with other federal protections, including those provided under the Americans with Disabilities Act.

The decision was celebrated by religious liberty advocates, who called it a major victory for people of faith and a long-overdue correction to decades of weak enforcement. Meanwhile, some labor unions voiced concern that the ruling could complicate scheduling and increase conflicts among employees required to cover shifts.

Legal analysts say the ruling is poised to transform workplace policies across the country, forcing employers to take religious accommodation requests far more seriously than before.

For Groff — who ultimately resigned after being repeatedly scheduled for Sunday shifts — the Supreme Court’s decision is deeply personal. He described the ruling as vindication and expressed hope that it would ensure no one else has to choose between their job and their faith.
