Didn't SCOTUS or somebody rule that employees had a right to wear religious symbols at work? In any event, we may be mixing up public policy preferences, with the state of the law at present. Of course, courts tend to favor the 1st amendment more than the 2nd.
But at any rate, I'm still of the mind that the employer makes the rules and if the employee doesn't like them, it's adios amigo.
I figured out a long time ago that I didn't like corporate rules so I figured I would be the employee and the employer. We get along much better that way.
