An employer has the right to deny you employment for any reason whatsoever--or for no reason at all.

As a practical matter, this is simply untrue. Even more so once employment has been awarded.

If employers property rights confer to them the authority to dictate the contents of an employees means of private conveyance, they similarly face forfeiture if an employees means of private conveyance contains illegal drugs. Employers face no such risk of forfeiture, therefore the contents of an employees means of private conveyance are beyond the employers reach.

My reply in post 13 should have gone to you as well.
