What law guarantees workers the right to organize and join labor unions?

The National Labor Relations Act (NLRA) is the legislation that guarantees workers the right to organize and join labor unions. Enacted in 1935, the NLRA allows employees to engage in collective bargaining with their employers, ensuring their rights to form, join, or assist labor organizations. This law establishes the framework for labor relations by protecting the rights of employees to organize for purposes related to their employment and setting out the responsibilities of employers in relation to labor unions.

The TAFT-HARTLEY Act, though related to labor relations, primarily addressed unfair labor practices by unions and imposed restrictions on union activities, which distinguishes it from the NLRA. The Equal Employment Act is focused on preventing discrimination in the workplace, and the Labor Management Relations Act refers broadly to legislation governing the relationship between employers and labor organizations, encompassing various acts including the NLRA. Thus, the NLRA is the foundational law specifically granting workers the right to organize and join unions.
