Interestingly, BigChoc, I once put in a formal complaint about my workmates' racism and subsequent bullying of me for speaking up against it. The company in question first made very sure to protect themselves against the claims of racism and then proceeded to ice me out. I ended up resigning as I couldn't face the daily struggle with such a complete lack of support.
I also consulted a solicitor at the time who told me since I was white, I had no grounds for complaint.
White male power is a damned sight stronger than we think sometimes. I really, really wish I'd gone to the local rag with the story as that might have changed something. I have all the respect in the world for Proudman, she's doing what I couldn't.
