It's happened again for the second time in a week. Charles walked into your cubicle and started a rant about his not getting enough support from you as his team leader. Before you could say anything, he accused you of playing favorites in assigning projects and not giving him the respect he deserved for his seniority and expertise. Then he gave you an angry look, turned around, and stomped off. You let it go the last time he exploded like this. And after cooling down, he came by later to apologize and give you a fist-bump of reconciliation. You've since learned, however, that the other team members have been on the receiving end of his outbursts and are starting to complain to one another about him. Charles is your top software engineer and has a lot of technical expertise to offer the team and you. He's a valuable talent, but his behavior has become intolerable. It's time for action.
