Discrimination lawsuit which eventaully lead to wrongful termination (in my opinion). Are those hard to win since their pretty much "he said she said"

the key to success is the basis for the discrimination. for example, one would be successful if the basis for the discrimination were race, religion or sexual preference. you cannot be demoted/fired because you are black or jewish or gay.  what was the basis for your discrimination ? did you file a formal written complaint stating that you were being discriminated against because if x ? you must put the employer on formal notice and give the employer the opportunity to remedy the wrong. what happened ? ed dimon, esq. 732-797-1600
