I agree that a lot of a manager's job may be tasks that are necessary to get things done, but I still don't see how your success isn't tied to your direct's/team's success? I understand that as a manager you may be given a stacked deck team wise, but even then I would imagine that you were put into that situation to be a change agent. If you weren't, well, that's someone sandbagging you and a different problem!
