Traditional Islamic dress advertises a certain rigidity of belief e.g.  homosexuals which may not make them the ideal candidate for certain jobs, particularly the many which require an open tolerant mind.

A Muslim friend of mine who runs a small Persian carpet repair business hired a young chador-wearing Muslim woman as a receptionist. All was well until she found out that one of his part-time employees had once been a stripper. She insisted he fire her or she would quit. She quit.

The government by being overly tolerant about the way people dress because of their faith is inviting problems which could be easily avoided by a more realistic policy concerning religious attire in the workplace  and in the delivery of government services.
