The FMLA makes it unlawful for any employer to interfere with, restrain, or deny the exercise of any right provided under FMLA; or discharge or discriminate against any person for opposing any practice made unlawful by FMLA or for involvement in any proceeding under or relating to FMLA.
An employee may file a complaint with the U.S. Department of Labor or may bring a private lawsuit against an employer. The FMLA does not affect any Federal or State law prohibiting discrimination, or supersede any State or local law or collective bargaining agreement which provides greater family or medical leave rights.
