What is the primary source of labor law in the United States?

The primary source of labor law in the United States is the National Labor Relations Act (NLRA). Enacted in 1935, the NLRA is foundational as it governs the relationship between employers and employees, particularly regarding the right of workers to organize, engage in collective bargaining, and participate in activities for their mutual aid and protection. The Act established the National Labor Relations Board (NLRB), which oversees and enforces these rights, making it crucial for maintaining labor peace and facilitating fair labor practices.

While other acts, such as the Fair Labor Standards Act, Occupational Safety and Health Act, and Employee Retirement Income Security Act, address specific aspects of labor—such as wage and hour laws, workplace safety, and employee benefits—none serve as a comprehensive framework for labor relations and collective bargaining like the NLRA does. Its broad scope and emphasis on the rights of workers to organize and negotiate collectively is what solidifies its status as the primary source of labor law in the United States.
