I think cbg is correct here. A potential disparate treatment claim based on gender and/or age would have had to have commenced within either 300 days under federal law and (I think!) within a year under state law. Moreover, you appear to suggest you may have signed a separation agreement which would presumably bar you from suing your former employer for any matter related to your employment.
In other states, similarly situated employees have advanced breach of public policy wrongful discharge claims contending that invidious employment discrimination violates state public policy. Unfortunately, as of a few years ago, the Florida courts did not recognize such a claim involving analogous public policy considerations.
With that said, it may still be worth your time to speak with a local attorney knowledgeable in employment law matters. The employment law area remains in a state evolution. Sometimes, things that are true one year become false the next. While I do not believe you can advance a viable claim of any stripe under federal or state law at this late date, it may still be worth your time to run this matter by a Florida attorney familiar with the most up to date changes in state law.
