Okay this actually does sound perfectly reasonable though.
Groff, a noncareer employee, worked as an auxiliary mailman in the Lancaster, Pennsylvania, area from 2012 to 2019, when he resigned. His job was to fill in when other workers were not available, including on weekends and holidays.
Initially, Groff was not asked to work on Sundays, but the situation changed starting in 2015 because of a requirement that Amazon packages be delivered on that day. Based on his request for an accommodation, his managers arranged for other postal workers to deliver packages on Sundays until July 2018. After that, Groff faced disciplinary actions if he did not report to work.
Groff resigned and sued the Postal Service for failing to accommodate his request. A federal judge said that the Postal Service had provided a reasonable accommodation and that offering anything more than that would cause undue hardship to the employer and Groff's co-workers. The Philadelphia-based 3rd U.S. Circuit Court of Appeals agreed in a ruling in May 2022.
Groups representing Christian denominations and other religious faiths filed briefs backing Groff, including the American Hindu Coalition, the American Sikh Coalition and the Council on American-Islamic Relations.
Groff had a job which he was fulfilling in full. Then Amazon put an imposition on the USPS that they deliver packages on a weekend which had not previously been a delivery day, which is a pretty clear case of a private corporation co-opting government institutions for their own needs, at the expense of government employees.
Because this had not been part of the original deal, Groff refused to accommodate the new demands on his time. Which is reasonable! He wants to spend his Sundays with his religious community during a regular time of community gatherings. It's not just about Christianity either, this got backed by Hindu, Sikh, and Islamic religious lobbying organizations in the US, for what I hope are pretty obvious holiday related reasons.
Also, the case hasn't been ruled in full. The Supreme Court, in a unanimous ruling (not just the fundamentalist judges) just said that the "undue hardship" on an employer to accommodate a religious belief has to be more than a minimal hardship. As in, "undue means undue, get the fuck out of our court, having one of the other auxiliary mail people handling Sundays would have been totally reasonable". Now it's going back to the lower courts to rule again, with that in mind.
