Although religion is a protected class under Civil Rights Act - and employers must make reasonable accomodations - safety trumps most everything. Turbans are a problem around machinery but also - for example - the creeper a mechanic uses to get under a vehicle. Any sort of head cover is dangerous around machinery (as are many other things - long hair, long beards, jewelry.) Once you have seen someone "scalped" you understand.

There are some interesting cases about religion and tattoos and employers as well. In certain circumstances - primarily cusomter facing - employers can ban visible tattoos. There are a number of restaurant chains that do this - the California Highway Patrol does - and lately - the Marines have placed restrictions on tattoos. Attempts to claim religious exemption from the visible tattoo ban have not been successful (as long as the rule is consistent.)

I fully support a ban on face cover. It is dangerous - the person with the covered face has limited vision - any place around any moving equipment it can get entangled - and for the safety of others - who is behind it?

For whatever the reason - religion or otherwise - faces should be visible.
