Insight from my brother on his experience as Union Steward......

brother was over yesterday and told me one of his coworkers was fired for coming to work drunk. I asked the usual questions..

Has he done this before? Answer no.
Has he been in disciplinary trouble of any kind before? Answer no.
What has the company done to employees in the past who came to work drunk? Answer, they've been sent to rehab.
is there a new person in HR, or new boss who handled this action. Answer no, same guy all the time.

My brother works at a large beer distribution warehouse. He said, "this is pretty bad to do this to a guy, when the business is in the business of selling a highly addictive substance". They even get an employee discount on the product.
