What is the primary law that governs relations between labor unions and employers in interstate commerce?

The National Labor Relations Act is foundational in regulating the interactions between labor unions and employers who engage in interstate commerce. Enacted in 1935, this legislation guarantees the rights of workers to form and join unions, engage in collective bargaining, and participate in other concerted activities for mutual aid or protection. It establishes the National Labor Relations Board (NLRB), which oversees the enforcement of labor laws and addresses unfair labor practices by employers or unions.

This act is significant because it provides a legal framework that promotes fair labor practices and helps to ensure that workers can organize without fear of retaliation. It also sets guidelines for how disputes between unions and employers should be handled, thus fostering a more balanced relationship in the workplace.

The other acts mentioned do not primarily focus on the relationships between unions and employers. For instance, the Wage Garnishment Act pertains to the legal procedures for withholding earnings to satisfy a debt, while the Fair Labor Standards Act primarily deals with minimum wage and overtime pay. The Davis-Bacon Act requires federal contractors to pay prevailing wages on public works projects but does not govern union-employer relations in the same manner as the National Labor Relations Act does.
