Management exists to minimize the problems created by its own hiring mistakes.
You can be management free and get things done unless "...some of your coworkers are worthless. There's always the one person in every meeting who keeps changing the topic, or doesn't understand the issue, or insists he knows more than he does, or is bluffing to cover his ass, or is jockeying for a promotion, and so on."
Nice article - worth pondering. Wrong hiring has always been one of my bugbears.
