Hang on a minute, this all seems to be getting OTT!!
Peter, It sounds as though you are just the type of person the government could do with to tackle the crime and punishment issues facing the country at the moment, tough and uncompromising. That is needed!! However, Mike states that this "problem drinker" has missed 1 or 2 days a month. That means 2 days out of 28, hardly call in "Alcoholics Anonymous".
Also, you give the impression that if you employ someone, you actually own them also and can control their lives. You do not own them, you employ them to work for you. Where does this attitude stop, do you stop them going to the football match if they happen to support the other team.
Whatever happened to a good old bit of "give & take" or "compromise" rather than the "hang em out to dry" attitude. Just find a simple solution that suits both parties, then , everyone is happy.
