As you know I'Ve been thinking about moving my career in a new direction. I am hoping that you will be able to provide me with a reference to help me jump-start my future.
I realize that I'm not in a position to offer you the kind of promotion you deserve I'll gladly do what I can to help.
Thank you. I'Ve really enjoyed my time here. I've grown both personally and professionally with this company.
And, as well as being a pleasure to work with, you'Ve been instrumental in helping us complete many key projects.
It will be hard to say good-bye. This office has become like a second home to me.
My feelings are mixed on the issue too. By helping you I'm losing a valuable and trusted employee. However I think you are taking a step in the right direction.
