Re: As an employer...
@AC ",,,I only hade one criterion. Was the employee getting the job done? I tolerated nose rings, tongue rings, blue hair and I didn't care how stoned they were or where they came from, if they produced the goods."
Only one criterion getting the job done, an employee's behavior at work does not matter. So an employee can be as abusive to you as they like bully their co workers, racist sexist etc, even be drunk as long as they get the job done?
I agree that employee appearance should not matter* neither should their lifestyle out of work. But an employee's behavior in work does matter. So taking drugs including alcohol outside work fine, as long as the affect does not carry over into work.
If an employee is visibly under the influence of drugs or alcohol then the affect has carried over into work and some sort of disciplinary action should be expected. Which is what happened with Zhu he was at work and visibly under the influence of LSD.
*It might for health and safety reasons e.g. tying long hair up, removing jewelry if working in food prep.
