In my experience this is completely wrong. In my experience, the more work you do, you're awarded with more work. Companies require you to continuously grow, and chase for promotion. If you're better, then you need to grow better too. If you're average, but cut the minimum, then you're asked to grow averagely too. In my experience, there is such a thing as being too good at your job such that your employer keeps asking exponentially more and more from you.
