I am the HR Manager in a large corporate office. Recently, one of my employees has been growing more and more unreliable. He is showing up to work late or not at all, coming in disheveled and smelling of alcohol, and not showing the same enthusiasm for his job that he once had. I know he has great potential, but I worry he may be an alcoholic. I don’t want to fire him, but I will have to if things continue. What can I do to help him?
