A boss bought pepperoni pizza for all employees one day, but a Muslim employee felt slighted because, she said, the boss knew of her religious beliefs about eating pork. She said she quit, but showed up the next day. When she wasn't on the schedule, she sued for religious bias and the EEOC took her case.
The court tossed out her lawsuit, saying the pepperoni snub didn't stack up to discrimination.
Bottom line: Make an effort to accommodate religious beliefs, but realize that one small slight typically won't constitute discrimination.
