If a worker believes an employer has retaliated against them for exercising their safety and health rights, they should contact their local OSHA office right away. A whistleblower complaint must be filed with OSHA within 30 calendar days from when the retaliatory decision was made and communicated to the worker. OSHA will accept a complaint in any language. Call 1-800-321-OSHA (6742) or contact your local OSHA office.
