Just went through this. Initial talks pegged a raise for going from department A to B at ~12-15%. Increased responsibility, etc. They (my manager, new manager, and CIO) signed off on it to move me to B. I was told there was no raise, it was a lateral move. They never told me this prior to moving me and I didn't sign anything. They wouldn't give me 5% no matter how much I argued. I found a new job, 30% over what I was making. I gave my 2 weeks, they offered to match instantly.
