“In any corporation, people tend to get promoted until they reach their level of incompetence.”, so said Dr. Peter
If you’re good at your job, then hopefully this will be noticed. Perhaps someone will say “Well done!”, maybe you’ll get a small pay rise. In most cases the best that’s likely to happen is that you’ll get promoted.
Thus your reward for being good at one job is to be forced (bribed) to do a completely different job, to which you may or may not be suited and which you may or may not like. If you do like it, odds are you’ll be good at that job too. This will be noticed and you’ll get promoted … as it goes. Of course, sooner or later you’ll end up doing something to which you’re not suited or you just plain don’t like. This is where you’ll stay for the rest of your working life, if you’re lucky. This is the Peter principle. It’s his fault and he has a page on facebook.
