OSHA conducts an interview of each complainant to determine the need for an investigation. If OSHA conducts an investigation, it will also obtain information from the employer and witnesses as needed. If evidence supports the employee’s claim of retaliation, OSHA will take action that may include requiring the employer to restore the employee’s job, earnings, and benefits, as well as granting other appropriate relief. Additional information about the investigation can be found here.
The procedures for investigating workplace retaliation complaints are contained in the OSHA Whistleblower Investigations Manual.
