Workplace and the 3 R's

I remember having conflict with my manager. She was always negative and just being a petty person. She would talk about her employees with other employees. It was just unprofessional. She would get smart with me in front of others and in meetings. One day, I asked her boss to mediate a meeting between the both of us to discuss the issue. I think that this assignment and the three R's really applied to what happened in the meeting. I was respectful and she was open to hearing what I had a problem with. I think that this really helped her understand what my problem was with her. She later apologized and worked on becoming a better manager. I thanked her. I also recognized her when she was doing something great to show her that I noticed she was working on bettering herself. This made the workplace much better and less hostile.
