It appears not everyone has read the entire post. According to the OP this is a bigger problem than just one person since he said that many other persons have problems with the same drug. Working with drugs in your system is akin to driving drunk. You may do it well, but at some point it's going to bite you and when it bites you, it tends to affect a lot more lives than your own.
If it doesn't affect the quality of their work, I'd leave it alone. It isn't really any of your business. Maybe this person just doesn't like coffee.
Maybe the mgr is doing blow as well. be careful or you might be the scapegoat. Research your retaliation/whistleblower process before starting
Already addressed, the OP is not in a position of authority. And the effect of the 'crime' is debatable, child rape is not. Black and white, hot button responses are kinda simplistic.
Why call the police? Just to make it worse for the worker? She doesn't need his life to be ruined for a mistake. I never made use of cocaine but it is a addicting drug and can make you do stupid things. Your manager is right, she needs help, not to be fired or have the cops on her.
Neither was McQueary, just an underling who failed to contact the proper authorities and thus perpetuated criminal acts against the helpless.
Cocaine possession is not child rape. The Sandusky crime has 0 in common with this OP's inquirey. Following up with the manager in charge though, in private, is fine.
If the co-worker is a nurse or in a position where them being high could physically harm someone else, definitely escalate it. Don't let these others talk you down from that.
Im not sure what state you live in but in some state's labor laws state something like, if employee is confronted with evidence of drug use while at work and admits to their problem they are allowed to keep their job if local drug rehabilitation is sought. They are protected as long as they admit and see help.
"Say that the workplace facility is a facility that takes care of people who are in a critical state, and said employee was theoretically high on this drug while taking care of people" Pretty damn close as far as I'm concerned: turning a blind eye or at best playing cya with coworkers who are entrusted in the care of those who cannot care for themselves. One is, of course, a bit more horrific than the other.
That's a broad statement. What kind of kind of drugs? An avid user can drive or work just fine on white.
and end up in ditches!!! Seriously if they could be putting others in danger report it to HR or the person in charge.
I have no idea what white is. Are you talking about cocaine? Are you saying that a coke addict can function just fine? Assume the following. A person is high on coke. They make an "honest" mistake (I.e. one a perfectly sober person could). They are drug tested and found to have coke in their system. What do you think the outcome of any investigation will be? regardless of how well a coke addict can function, I would not want a coke addict taking care of me.
