Question? Who is the best worker? The one that complains most? In most cases we will only remember the most complaining one. But on the other hand the best one will be one of those that is quiet, works their hours and leaves for home. The most complaining one will maybe just do the minimum effort, but then it comes to promotion, you will at least know his or her name. Think about it. If you're a worker a good reason to complain more. Otherwise your boss will never recognize you.
