It is against the law to be discriminated against for reasons of gender, age, race or disability.
I experienced this first hand after 12 positive years with an employer.
See an attorney. It is against the law.
I settled out of court for much much less than I could have if I had seen it all the way thru. They had much deeper pockets it started taking a financial and emotional toll....so I settled. i feel I did the right thing. I Still feel I was in the right.
Its not an easy course, but my main motivation was to stand up for what was right and make it less likely that it could happen to someone else.
