What do you believe is the basis for discrimination. In order to present such a claim it has to be based on PROHIBITED discrimination such as race, age sex, national origin, creed and/or disability. Keep in mind that almost all employer will not admit to such bias and the burden on you is to prove it, which can be a difficult case because you have to often rely on circumstantial evidence.
In order to explore a potential claim, I would consult with an attorney experienced in such discrimination BEFORE you file any charges. You can find an attorney through this website, your local bar referral service or www.mwela.org and www.nela.org, which are two organizations composed of plaintiff side attorneys, many of whom are seasoned trial lawyers in this very area. Good luck.
