Explain to him just what you explained to us. #1 You're honoring his father by hiring him, #2 You expect him to do twice the work #3 put somebody between him and you as his direct supervisor. After that it's business as usual. He makes the grade or washes out. Either way, you are off the hook and can sleep at night. When he comes to you for favors, etc., refer him back to his supervisor. Tell the rest of the family what you're doing and what your expectations are. It's his choice, ultimately.
