A few questions: What was the nature of your family leave? How many employees does your former employer have? How long have you worked for that employer? (I also assume that you are a woman. Forgive me if you are not)
Two laws may be of help to you:
Family and Medical Leave Act which protects employees for up to 12 weeks of leave
Pregnancy Discrimination Act which makes termination based on pregnancy a form of gender discrimination and therefore illegal
These laws have requirements about the number of employees and the amount of time worked for employers, hence the questions.
Please seek an employment or civil rights lawyer for legal advice. There may be other laws applicable that I am not aware of.
