Religion plays a fundamental role in many people's lives. For some, practicing religion is a much more active process than just attending services. Some religions require adherents to wear specific clothing, for example. This can create issues when a religious person seeks out employment, because those of a mind to discriminate based on religious beliefs can easily identify followers of certain religions based on that clothing. Fortunately, there are laws preventing this and a recent United States Supreme Court decision has reaffirmed these protections against religious discrimination.
