Well I wrote my letter and went to the Boss. I asked him to keep the conversation between the 2 of us and expressed my concerns. It went along swimingly!
He saw and understood and agreed with my points and assured me this review was merely feedback that 1 supervisor and would have no bearing on my future endeavors with the company. He is really a great boss and I will be glad to be promoted someday and work more closely with him.
See, never back down, never think you cant be heard by those that matter and never think someone elses answer is the end of it all. You can always go beyond, you can always find a way to be heard and recognized if only you believe in yourself enough.
I walked out of there with a grin on my face and a little lighter in my footsteps happy once again.
