If you aren't a friend of someone, don't try to move up or apply from within, usually not fair practices that I have seen in moving up.
Be careful who to trust, those who say they are your friends will tell anyone else what you say, when regarding work, boss, issues etc.. trust is hard to come by.
Do what I say, not as I do.... If you have a culture or mission statements you say are your company core values... I would think all management should live by them.
