Under 1977.9(a), are employee complaints about workplace safety or health protected from employer retaliation?
Yes — employees are protected from discharge or discrimination for filing complaints made under or related to the OSH Act. The rule explains that a complaint made “under” the Act (for example, a request for inspection) or a complaint “related to” the Act is covered by Section 11(c), so an employer may not retaliate against an employee for such complaints. See the protections described in 1977.9(a) and the general [1977] (https://www.osha.gov/laws-regs/regulations/standardnumber/1977).
