Have you noticed that working your behind off, making sure there are no complaints against you, always going the extra mile never leads to a promotion, raise, or bonus at this place? No, what it leads to is having more work piled up on your already overloaded plate.
Hey, we laid off a bunch of people, but that guy over there always finishes all of his work on time and nobody is complaining about him - that means he can take more! That seems to be the thought process of our management. So why bother?
