dilbert will end up firing dogbert. he'd better find a way to fire PHB ...
if he doesn't, then he has some benefits having some **** manager. wally has plenty benefits of this situation, but that isn't obvious for dilbert.
Regarding leadership and the organizational tolerance for diverse internal opinions, the old adage, "Like attracts like," holds true. Or, as my wife once said to me, "I'll listen to your stupid opinion as long as it agrees with mine!" (True.)
