Ron,
I think it is much deeper than this, it is her insecurity that is driving this. She sees you as a threat and wants tether what is unfettered. I just recently left my position at a very large bank due in part to a supervisor that tried her best to beat me and other co-workers down, it took a while but I saw through that she was doing it due to her incompetence. This method is starting to backfire on her and likely she will be the next to go. I am lucky as I am in the position financially that I could just move on, and a much better opportunity is coming my way. I hope that in the end you may continue wearing your kilts to work. Corporate America just kills me because of the current buzzword about diversity, and how its use is so subjective.
