Ironically, we are much laxer on those with more responsibility. When was the last time a middle manager or senior executive had to pass a piss test to be employed? It's routine in blue collar work.
Not in Wall St for sure. Or they make sure the "right people" know it's coming ahead of time so they can buy the right stuff to cheat the tests. Plenty of drug use by managers in a lot of organizations I've been involved in. None were ever fired for it. A few were fired for the damaging behavior that resulted from it.
Glossed over it. Good catch. Interesting enough, my post still is pretty accurate reply if you drop the "not" at the beginning and look at it from who gets ahead in their special clubs.
