The US Supreme Court has sided with an evangelical Christian worker who was denied requests to take Sundays off from his post office job for church and rest.

Gerald Groff’s request for Sunday’s off came after the US Postal Service started delivering Amazon packages on Sundays. It said granting him the time off presented a scheduling conflict – and a burden on his colleagues.

Groff’s supporters say it’s a landmark victory as no one should be forced to choose between their faith and their job. He says he hopes the decision allows others to be able to maintain their convictions without living in fear because of what they believe.
