Hello, just recently found that my colleague has been secretly promoted and no one has been informed, the way i found out was through some files and put 2 and 2 together. The reason why is that she is very close with the manager and they always gossip about other colleagues etc. The reason why I am upset is that I have applied for promotion two years ago and three people have been promoted after me. I am planning to tell this person that i have heard from someone and confront her and also since she is close to the manager she will definitely let her know. I just want to make a point that they cant get away with stuff like this. And also the role that is given to her is the role my manager used to do so basically like a managerial role and will definitely upset other team members as it shows favouritism. How do i do this?
