That suddenly makes the comments I give someone in feedback vital to their future job so being at all negative would be seen as a big punishment. > For example: when a candidate mentions "references" on his resume, they are always meant to give positive feedback about them which is why again its broken. Many jobs don't give any feedback at all. The purpose is to prove that you did, in fact, work there with that title for that duration. General question: are un-vetted reviews about someone by completely unknown people a reliable indicator of future performance? If places don't give reliably truthful reviews, why would you expect that the 360 feedback wouldn't turn into exactly the same thing?
