Hi, how long have you been working there? If you have been fired you should certainly talk to an attorney to see if you have a claim.
Generally speaking (this applies to federal law - I don't know if there is a FL specific law that applies) discrimination on the basis of pregnancy, childbirth, or related medical conditions constitutes unlawful sex discrimination under Title VII, which covers employers with 15 or more employees, including state and local governments. Title VII also applies to employment agencies and to labor organizations, as well as to the federal government. Women who are pregnant or affected by related conditions must be treated in the same manner as other applicants or employees with similar abilities or limitations.
My answering this question does not form an attorney-client relationship. Always retain a qualified attorney before taking any action. My office offers free consultations. www.jrandolphlaw.com
If you are being discriminated against because you are pregnant, you are protected under the Florida Civil Rights Act and federally under Title VII. You should contact an attorney in your area to discuss your particular case further. Depending on the specifics, you could have a case.
