history: My supervisor took all the credit for a new client I brought in. He didn't even recognize that I was involved at all, much less that I did all the work. My supervisor totally stole all the credit for a client I brought in. That's a bad supervisor. Did you call him/her out on it? I totally did. And let the CEO know about his behavior.
current: I hope he got in trouble!
next: Unfortunately no, the CEO thinks he can do no wrong. Eventually he'll figure out what a jerk he is.
