Be very carful on docking pay as there are labor laws that can be broken very easy. What would be better to do is dock the amount of hours for a time. Best time to do it is in the morning or at losing. Have them go home an hour sooner if time of closing or an hour later if at opening or...both. Tell him this is due to him being "untrustworthy" and you have to keep a 100% eye on him for a time until he can show that you can trust him once again. What this will do over all is cut his pay...he will lose money from him weekly paycheck and this can really hurt someone and make them think before they do something again dirty. Just my two cents...but don't go docking pay with out knowing your state laws about pay docking.
