I've read a fair amount recently about the need for employees to get manager feedback or have an annual performance review. In fact, it seems like I've been reading about management feedback for a long time now and how the only way for employees to understand how to improve is if their supervisor decides - or is forced - to give an annual review. You will never hear me complain about hearing too much about good, constructive criticism, though, because I find it very helpful, but I do see it as simply a micro-level review.
