I have a situation where this week one of my peers was promoted to be my supervisor. This person is known to be volatile and while we have had a friendly relationship in the past even in the first few days her behaviors have changed. I anticipated this so I offer only as background info.

A week ago she invited me to lunch so we could discuss "everything I didn't like about our work environment" because when she started a year ago I had let her know I was struggling with the poor communication structure.

My question is this - what (even in a non-performance review setting) is appropriate or not for her to ask. I am not planning to give her any information at this point but would like to let her know if she presses me that our working relationship is different now and I prefer to keep these types of discussion in the formal setting of the performance review.

Additionally after several requests to receive a performance review from my former supervisor I have never been reviewed so the former peer will now be doing my review at some point.

Would that be a good approach or is there another approach anyone could suggest?
