Have all employees review company policies and have them sign a statement that they have read and understand. Taking this action will benefit you if you have to make some moves and may wake some of them up. Someone mentioned documentation, I agree 100%. You should ensure all your policies are current and legal, and that you know them. If some of the problem children are supervisors empower them and make them do thier jobs. If they don't get with the program write them up first. Clear communication is key.
