How much are you willing to work?

One of my employees has voiced an interest in another position, actually a management position that opened up. I told him it might be a good fit for him. This despite giving him a 50% rating last year. Actually, part of me would rather see him move on so I don't have to deal with him anymore.

I know the person in the position currently (she's leaving end of month) and she probably averages 10-12 hour days. She's a good manager. In reviewing the position with him, I asked him how hard he's willing to work.

His reply: 80%.

Explains a lot.
