This year, the company I work for is implementing a long list of questions I have to answer about my manager. This is new to me, as my prior experience with performance reviews has been entirely downwards. I'm not sure how to approach this.

Truthfully, I don't have any complaints for my manager. When I tell them I have a problem, they usually fix it, and they do a good job of preventing it from getting to me in the first place. I hate that HR is forcing people to come up with something negative even if they don't want to.

Usually I try to be vague as RK suggests[1], but I don't think that's possible this time because they all ask for specific examples and are asking me to quantify the negative effects the manager had on the company.
