Briefly I went for a promotion I didn't get, the guy who got the job was promoted over me and in my opinion is arrogant and patronising (I have had problems with him before). I have just had a meeting with him and another boss (another guy I don't have much time for either) and I know I am coming across as difficult and petulent. How can I stop this? Need to develop some distance and be professional - anyone got any tips...please.
