> Hiring manager A doesn't want subordinate employee B who knows more about the work of A than A does, or is better at office politics, meeting customers, managing people, etc. Or, manager A wants only subordinates (secondary, submissive, subservient, subordinate, dedicated, devoted, obsequious, obedient, etc.!).

In every job that I've had, I've known more than my manager. This isn't particularly surprising because their job is to manage rather than know the things that I know.
