I actually told my admin during a friendly budget/staffing conversation: "you're either going to do it for me or you'll do it for the guy that teaches here next year. Either way, you're going to do it. We get along, you might not get along with the new guy. Why not do it for me?"
They said no.
I went and applied for several other jobs. They got the emails asking for references.
They said yes. We've all been happy ever since.
