The Florida Supreme Court ruled on April 17, 2014 that employers cannot discriminate against pregnant women under Florida state law. Florida's law protecting women against workplace discrimination also covers those who are pregnant, the state's supreme court said in overturning a trial court ruling.

A lawsuit filed by a former worker at a property management company was reinstated, the appeals court said pregnancy is "a natural condition and primary characteristic unique to the female sex," and covered by Florida's civil rights act. [The case is Delva v. The Continental Group Inc., SC12-2315, Supreme Court of Florida (313404L: US)].

Pregnancy discrimination in the workplace is prohibited under federal law. Some states including California, Illinois and New York, also have laws guarding against pregnancy discrimination, either through explicit statutes or by way of legal findings, according to women's advocacy group Legal Momentum.

Although Title VII of the Civil Rights Act of 1964 only prohibits workplace discrimination on the basis of race, color, sex, nationality, religion, age or disability, workplace discrimination laws have also expanded recently to include pregnancy, sexual orientation and gender under the prohibition against discrimination based on "sex."

Under federal law, the Pregnancy Discrimination Act (PDA), an amendment to Title VII, prohibits discrimination on the basis of pregnancy, childbirth or related medical conditions. In 2013, the US Senate approved a bill outlawing workplace discrimination against gay, bisexual and transgender Americans. The Employment Non-Discrimination Act (ENDA) outlaws workplace discrimination on the basis of sexual orientation or gender identity.
