"not employers testing prospective employees which nobody is disputing the legality of"

I disagree with that one and hope to one day have a supreme court that isn't slanted towards the corporation. Myself I've never had to submit to a test but for those that do you are giving up your basic constitutional rights each time. Yeah the supreme court say's that's ok though. We are gradually approaching some perverse form of slavery where once you sign on you are owned. Your bodily fluids or hair are their's. Your credit is checked. Your background is checked. Your past online activity can be checked. Some, epecially the govt, interview your neighbors. You get paid for x number of hours but are owned 24/7. So, if a publicly owned corp can do all of that to you why can't you or shareholders expect to see the results of a quarterly drug test of all officers of the corp? Why not an annual background check to make sure an officer isn't in debt trouble and about to take the corp down? Who is more dangerous? As we've seen time and time again it's the officers who destroy a corp not an employee.

As usual TJ/TK is FOS. I've worked for plenty of large corps who don't test and would if it saved them a dime.
