salukigirl....I wonder at this point if it is important for you to take stock in your values and what you feel comfortable with in the work place and maybe find another position with another company that does not condone the use of alcohol and drugs while working.
I would hate to see you having more difficulties if something should happen to one of the employees or any other individual who was hurt because of their alcohol/drug use. Not only would you have emotional difficulties over something like that but there could very well be legal ramifiactions.
I would be scared to death to supervise such an unruly bunch of idiots...but of course that is my personal feeling about it. I hate the idea that you might be in for more than you bargained for with this position and company.
Something to think about no?
