No one else works on my code. I am not even sure that someone else would even understand it. It is critical code. So, it is not a good idea to fire me either, which would be "hurting my career", but which also seems quite impossible to achieve. All you need to do, in order to be in a position to ignore office politics, is to be the sole maintainer of a pile of mission-critical code. I've seen people come and go, but I don't and I work from home!
