It is illegal for an employer to fire, demote, transfer or otherwise retaliate against a worker for using their rights under the law. If you believe you have been retaliated against in any way, file a whistleblower complaint within 30 days of the alleged retaliation.
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.
