Q: “I have become very disillusioned with my manager. ‘Brian’ and I worked well together as peers for several years, collaborating on a variety of successful projects, until a new CEO promoted me and demoted him. Recently, that CEO was replaced by a guy who worked with Brian twenty years ago. Now he has decided to make Brian my boss. Unfortunately, Brian has turned out to be an ineffective manager who doesn’t want me to have any visibility. Some trusted colleagues have shown me emails in which he takes credit for my work. Brian praises me to my face, but apparently does not share these positive comments with higher-level executives. I’m starting to feel that leaving is my only choice. What’s your advice?”
