I like this concept. I have always thought that the exit interview, while worthwhile for some information, is really a little too late. The decision about the company, either positive or negative, by the employee has already been made, and well, obviously, the person is walking out of the door. It seems to me that the best time to get information from your employees or tell them that you "love them" is while they're still under your roof.

With the economy recovering, in order for you to retain your best talent, now may be a good time to "buddy check" with them to see if they really are happy working for you. And if they're not, why not? What changes could you make to persuade them to stay? Like they say in the article, be forthright about asking what could entice them away and be prepared to look into what you could do to keep them working for you.
