So your argument is that anything an employer wished to require of his employees would be OK?

Regardless of of the Constitution or bill of rights?

Regardless of of the Constitution or bill of rights?

The Constitution and Bill of Rights applies to government, not to private entities. One exception would be the 18th amendment. The only one to ever be repealed.

I guess it can be argued that section 2 of the 21st amendment, the first section of which repealed the 18th, does apply to private entities, because it prohibits actions by those entities, rather than giving government the power to prohibit those actions (importing booze into states where it's illegal).
