I work for a company that champions their diversity and inclusion stuff EVERYWHERE. I'm partially deaf and wear hearing aids. At a company hosted Christmas Party they had this Cards Against Humanity style game - it wasnt CAH, all of the cards were pretty innocent - like speak in an accent, treat the card as a baby, etc. New guy got a card that said "Imitate someone at the table". He turned to the guy next to him and said "I can't hear you, can you repeat that" - mocking me for being deaf. One of people at the table caught on really quick and was like WTF did you just say?

Nobody laughed. The other person reported the incident to HR and I had to recap the whole thing to them. The guy never apologized for it. HRs resolution was that I could "leave the team" or the company if I didn't want to work with him anymore. This person was one of five people on my team. I didn't leave the team mostly because my manager was pretty supportive and didn't agree with the HR outcome.

So yeah. Coworkers aren't your friends and neither is HR. We got 84% on our D&I score for employee engagement ratings this year.
