Architecture & project management. I was promoted from contractor to employee and was told basically not to spend any time on the project anymore because there are new (bright, capable) contractors to work on it. But it's never in a contractor's best interest to take responsibility for the big picture. So I spend lots of time testing contributions (okay but not much fun/reward) and being a project manager (detestable and a black mark on my resume afaic). Why I took responsibility when I was a contractor? Clearly I do not always act in my own best interest.
