> On many of the occasions in the past when I've given meaningful feedback... despite the "anonymity", that feedback has been repeated to me verbatim by a manager in later conversations. Often in a passive-aggressively angry or intimidating way. This happened to me once and that was quite enough. Filling in "anonymous" surveys doesn't benefit employees at all. It's going primarily towards the company or department performance indicators. Putting in a complaint might just harm your position. I agree: if something needs fixing then it needs to be addressed openly and informally first: discuss it with colleagues and see what support you have, discuss it constructively with a manager and see what they're willing to do about it.
