How to approach an employee suspected of drinking?

The first thing to do is to make sure the information you have received about this person is accurate. Check whatever public records, and co-worker statements to evaluate the system. If confident the person has a problem, it's best to schedule a private meetingÊand relay any concerns in a concerned manner lacking rancor. It helps to praise something this person is doing well on the job in order to cushion the criticism of his or her drinking.
