I was denied a promotion and was not allowed to give a presentation because my boss misjudges me because of my background. What to do?

Answer 1

You can suck it up, buttercup. We don't always get what we want, and I sincerely doubt your background is a factor.

Answer 2

You need to communicate with the manager, that you feel you are discriminated against. And if they do not stop, and you are efficient, you may challenge them. Unhealthy workspace may bring your self esteem down for no reason. Quit where you are not valued. ‘Stress diaries’ a book by Dr. Rachna Khanna Singh offers great advice in such matters of your work-life.
