(23,272 posts)in the middle of the DMV for example - their employer can order them to pray in a back room, even if it's not a great situation.
An employee is hired to work, not engage in personal religious campaigns during work hours.
Typically proselytizing is forbidden in the workplace (I'm looking at the religions who emphasize proselytizing like Mormons, evangelicals, or Jehovah's Witnesses as part of the full practice of their faith).
Religiously inspired discrimination is typically forbidden - Orthodox Jewish men are not allowed to discriminate against women as second class citizens even as their religion dictates that. On their own private time they can refuse to sit next to a woman, acknowledge her or shake her hand. Not on work time.
Operating dangerous machinery while wearing loose religious garments or hair isn't permitted - niqab and welding come to mind.
I could come up with a million examples where employers absolutely can and do tell folks how they can practice their religion (or not) on the job.
As for an Orthodox Jew, well my physician friends told me they were told to suck.it.up or they'd never get hired for a residency or as a first time hire in a hospital. They expected and understood they'd be on call 24/7. Maybe as they gained seniority they could arrange holiday swaps but NONE of them expected the hospital or medical organizations to accommodate their religion during those early years.
