I was a manager at one point, and the combination of #3 and #4 basically killed my interest in management. As an IC, your manager can tell you to do something that makes no sense. They can either agree with you or disagree about how stupid it is, but if it comes from above it has to be done. As an IC, you just do it and try your best to disconnect emotionally and get it over with. As a manager, you first listen to your manager tell you to do something that makes no sense. You push back, but they say your team has to do it. You take it to your direct report and they push back, and now you are forcing somebody to work on something they rightfully don't agree it. Unless you are an a$$shole, it's hard to disconnect emotionally when you are forcing somebody to do something you don't agree with. Do that over and over...it really takes a toll.
