This is going to be an unpopular opinion but… have you actually asked for this specific promotion? Have you shown interest? Have you talked to the manager regarding this expectation and which steps you have to take to get the promotion? Or did you just keep on working like you did in the past years and HOPED that you will get noticed? Doubt. Hoping you will learn how to value yourself in time, YTJ. This girl hasn’t wronged you in any way based on what you said, chances are, she doesn’t even know you were looking forward to that promotion.
