Managing Upwards: greatest idea since sliced bread

Can you imagine how fantastic it would be to get the chance to "rate" your boss? Or how enlightening it might be, if you are a boss, to find out what your employees think of how you run the show. This is an idea that will likely catch on right after hell freezes over, but I love the notion of doing a boss evaluation and getting a chance to to tell the people you work for why you feel justified stealing those post it notes.
