I basically caught a couple of managers making derogatory comments towards a certain cultural community on a conference call. I called the HR person and explained everything. She promised to investigate and update me. That was 3 months ago and still no word from her. My manager resigned a month ago, so I'm on my own for this one. I want to do the right thing. My boyfriend told me to wait a couple more weeks and escalate this issue to the HR person's boss because they are obviously trying to sweep it under the rug.
