You make a great point. I think it is important to be upfront and honest with your boss about your intentions. Unfortunately, there are a lot of bosses who lack the ability to communicate openly, then shun you and throw you out the door.

I have been lucky enough to work for a great boss where I can be open about my intentions and what I am trying to accomplish. If an individual is in a job where he can’t accomplish what he wants, then he should look elsewhere, but be open with his boss about why he is looking. It helps the relationship and lessens the chance of getting a bad referral.
