The one thing I will say, as a manager of a group, is that we are often constrained in what we can do, and this we can end up in a situation were we want to promote somebody, but the higher ups won't agree, and you find yourself stuck - you've got somebody you think deserves more but you can't get it for them, and you can't tell them you tried, because that's kind of a dick move, trying to make yourself look good without actually helping them.
But, yeah. If the company won't pay you for the job you're doing.....
