I don't think I can really help, but for what it's worth -- you're definitely not alone. You may not have this option... but in my org, we can submit feedback to a co-worker's manager at any time during the year. I have, on occasion, submitted negative feedback. I really _really_ dislike doing that. I feel dirty every time. But I view it as a responsibility. I work for a company that designs & manufactures devices that can mean life or death; every time I submit negative feedback I tell myself that it's for the well being of the end-user. When I submit negative feedback, I avoid being vague; I give precise, specific, and well documented examples and try to be as objective as possible. When other co-workers confide in me that they are frustrated with someone else, I give them the same advice: I encourage them not to tell me too much - let's be professional. But, because I respect them as a professional as well, I trust that their feelings are valid and not unfounded. I then tell them to make sure the appropriate people (managers) know - and point them to the feedback link. My hope is that if a manager gets enough negative feedback on a report (and it's all consistent), the problem will sort itself out during the next round of layoffs. Edit: For each piece of negative feedback that I submit, I try to counter act that with positive feedback about somebody else. I'd like to think it acts a little bit like up/down voting.
