Recently there was a restructuring at work and everyone who works in my building - including my old manager - now works in a different division, except me. I now have a temporary manager, awaiting a new one.
I never had a great relationship with my old manager and soon before the restructuring he did something underhanded to me during my review. It is not clear if it was intentional or unintentional, but after I pointed it out, he never tried to rectify it or admit a mistake was made. It is very possible he cost me money in either my raise or bonus. I was very upset and was looking for a new job until the restructuring took place.
Soon my new manager will be coming on board. He will be located in another city. I expect I may see him about once a month or so, maybe less. I hope to talk to him about once a week.. My objective is to make sure my old manager no longer has any influence on my career and future reviews. Just to be clear, I do not want to get back at him, just insulate myself from him.
One other point, my old manager is currently the leading expert for the business domain I work in, and my new manager is much more knowledgeable about the technical side of my work. I would not be surprised if my new manager consults with my old manager about my performance.
Do I ask my new manager not to consult my old manager during review time? If so, do I tell him the details of what happened, or only say enough to show why I am asking? Do I say nothing, keep my head down, and hope for the best? Or is there another path?
