Men should have frank discussions with their male subordinates about appropriate conduct in the workplace. If they see a direct report putting their hand on a woman's shoulder or being overly complimentary or affectionate, take them aside and let them know they shouldn't interact with women any differently than their male colleagues when it comes to touching and paying compliments. If you mess up, apologize. Most women don't expect anyone to be perfect, but it means a lot when you acknowledge a lapse in judgment.
