According to his attorneys, Groff v. DeJoy could have significant implications for the religious rights of employees across the country.

Groff began working for the United States Postal Service (USPS) in 2012 but did not experience problems until 2013, when USPS started requiring him to work Sunday shifts as part of the service’s contract with Amazon.

Because he believes that working on Sundays would violate the Third Commandment’s obligation to “keep holy the sabbath,” Groff requested a religious accommodation to not be scheduled for work on Sundays...

[H]is request was granted, allowing him to work extra shifts during the week instead of on Sunday.  But in 2016 the postal service rescinded its agreement with Groff and began scheduling him to work Sundays again.

Groff was made to look for replacements for every Sunday shift, resulting in his missing several shifts.

Rather than waiting to be fired, Groff resigned from his position with the postal service in 2019 and sued, saying his right to practice his religion had been violated.

The Third U.S. District Circuit Court ruled against Groff in May 2022, siding with the postal service’s claim that Groff’s religious accommodation request placed an “undue hardship” on the employer.
