This woman is becoming increasingly negative mostly towards me. When she was first hired we went out for lunch together all the time. About 3 months ago we switched jobs and now she has my old job. When she started with us everything was great, since the job change things are not so good. She is quite rude to me and won't speak to me unless absolutely necessary. There are only 5 of us in the office and her poor attitude is poisoning the environment. The boss has talked with her but I truly think this problem she has is just with me. Any thoughts?
