I am not a lawyer and this is not legal advise. I have worked in the area of employment law for many years.

FIrst of all.... in most jurisdictions you have 300 days from the time the discrimination occurred to fill a claim of discrimination. You may be past that.

Another thing about discrimination...it must be based on your membership in a class, race, gender, religion, ethnic origin, age (over 40) or disability. One thing I try and stress with people is that being a jerk is NOT illegal. Being a crappy boss is NOT illegal. Wrong, yes....unfortunate if you are the employee, yes...but not against the law. There is no law regarding who should be laid off or what order. Nor is there a law requiring severance. Nor is an employer required to pay one person more or less than another for any reason other than they want to do so (unless it is based on race, color, religion, ethnic origin, sex, age or disability.)

Even though most settlement agreements include a confidentiality clause.... you are right ....these things become known.

I have worked with people who could not shake their focus from the wrongs that have been done to them. That prevents them from looking forward and moving on. I agree that living well....succeeding.... is the best revenge.

Put the energy you are wasting on these jerks to better use. Be successful. You are very talented and you would be "letting them win" to do anything less than be happy and successful.
