Under 1977.3(a), can an employer discipline an employee for filing an OSHA complaint?
No — an employer may not discharge or otherwise discriminate against an employee for filing a complaint under or related to the Act. The rule explicitly protects employees who have "filed any complaint under or related to the Act," so disciplining someone for making such a complaint would violate 1977.3(a).
