What I was used to from the west coast was an attitude that management is just an annoying, mundane chore someone has to do so that the smart people can get their work done. Think of an academic department at a university, where being the chairperson of the department is actually something of a burden that nobody really wants to do; they’d much rather be doing research. That’s the Silicon Valley style of management. Managers exist to get furniture out of the way so the real talent can do brilliant work.UNQUOTE (source here)
Personally, I've been on both sides of the equation, and I can relate to the above even though it does take a rather extreme position.
But it is worthwhile every now and then to take a good look around and to ask yourself if you are a Manager: "what is it that I actually do that makes a real difference to this company's objectives ?", and if you cannot think of a ready answer, it's probably time to start worrying.
