Just had a look at the article and apparantly the guy was an elder who told his employer he needed those two times off when he started his employment. He was later transferred to another branch where the manager told him he had to work Sunday. He would not work Sunday so he was fired.
So I think in this instance the elder did nothing wrong. Here is a link to the story
