yeah, i know.
so lets say a guy works at a programming house, been there for 5-6 years. he's an excellent employee, gets along great with everyone, consistently one of the top producers and has outstanding quality in his work. the company is making alot of money off this guy and his work.
a random piss test comes up and come to find out, he's an every day smoker, not a lot, just like a half a j or a j a day.
what would be the reasoning for firing this guy? he can obviously do his job, and replacing him would cost the company in lost revenues and training a new employee.
or what if this guy is stopped at the door when applying. he has an outstanding work history, worked with/for the biggest names in the biz, he is a god and wants to work for YOUR company because you just happen to be closer to where he lives...but you pass him over because there are traces of weed, and nothing else, in his system from 2 weeks ago.
