Every person of color that I worked would work hard get nothing and watch non POC get promoted instead.
I've watch every type of senario. For me it seemed like every time I reached the bar for my performance, the bar was moved even higher making it unattainable.
This also happened to my friend who was working on a account and wanted to be account manager. The allowed her to run the account and the team. Then hired a new account manager for her to train.
This happened every time.
