Which agency must workplace safety grievances be reported to?

The agency that must receive reports of workplace safety grievances is the Occupational Safety and Health Administration (OSHA). OSHA is responsible for enforcing workplace safety and health regulations across the United States. It provides guidelines and oversight to ensure employers create safe working conditions, and employees have a right to report unsafe working conditions to this agency. By reporting grievances to OSHA, workers can initiate inspections and investigations into workplace safety issues, enabling the agency to take necessary enforcement actions against employers who violate safety standards.

While the National Labor Relations Board deals with issues concerning collective bargaining and labor rights, it does not specifically handle workplace safety grievances. The Department of Labor oversees a wider range of labor-related functions, but OSHA is specifically designated for safety matters. Similarly, the Employee Relations Board generally deals with workplace disputes related to labor-management relations rather than safety grievances. Thus, OSHA is the appropriate agency for such reports, making it the correct choice in this context.
