[quoThat isn't strictlyte=kevingg]good luck looking to make a discrimination case if you are a straight white male! [/quote]

That isn't strictly true. It's been done in the UK. What generally happens is that some white, straight male is passed over for a promotion (which he has a reasonable expectation of) in favour of some other ethnic group (OEG). For an unlawful reason. Like discrimination in favour of that group. Criteria for promotion is set higher for the WSM than the OEG etc, etc.

I have personally been in that situation. I was carrying out the same duties as a female member of staff and a male member of another ethnic group. The problem was that they were both one pay grade above me. Having checked the legal position, I objected to this on the grounds that UK law expressly forbids discrimination (other than under certain very tightly delimited circumstances)for sex, race, creed, religion, marital status or sexual orientation. Then I requested a formal meeting with my Line Manager and raised the matter with him. I got my promotion.

The important thing is to be very certain as to the legal position and to act in a reasonable none threatening manner. Give them the chance to be graceful.

I should also add that one has seen members of other ethnic group's being mistreated and I have always made it my business to step on such conduct. I have always taken the view that you promote on ability and track record only. Anything else is dishonorable and despicable.
