The Third Circuit affirmed the order that granted summary judgment in favor of the U.S. Postal Service (USPS) in this religious discrimination suit. Groff informed USPS that he was unable to work on Sundays. USPS offered to find employees to swap shifts with him, but on more than twenty Sundays, no coworker would switch, and Groff did not work. Groff was disciplined and ultimately left USPS. Groff sued, alleging Title VII violations for USPS’s failure to reasonably accommodate his religion. First, the Third Circuit held that because the shift swaps USPS offered to Groff did not eliminate the conflict between his religious practice and his work obligations, USPS did not provide Groff with reasonable accommodation. However, the accommodation Groff sought (exemption from Sunday work) would cause undue hardship to USPS. Therefore, USPS did not violate Title VII by declining to grant his accommodation.
