Gerald Groff, who lives in Pennsylvania, served in 2012 as a rural carrier associate at the United States Postal Service, a position that provides coverage for absent career employees who have earned the ability to take off weekends. Rural carrier associates are told they need flexibility. In 2013, Groff’s life changed when the USPS contracted with Amazon to deliver packages on Sundays. Groff’s Christian religious beliefs bar him from working on Sundays. The post office contemplated some accommodations to Groff such as offering to adjust his schedule so he could come to work after religious services, or telling him he should see if other workers could pick up his shifts. At some point, the postmaster himself did the deliveries because it was difficult to find employees willing to work on Sunday.
