Which legislation protects the rights of employees to unionize?

The National Labor Relations Act (NLRA) is the legislation that specifically protects the rights of employees to unionize. Enacted in 1935, this law aims to secure the rights of workers to organize and engage in collective bargaining with their employers. It allows employees to form, join, or assist labor organizations and prohibits employers from interfering with these rights. This act is foundational in establishing the legal framework for labor relations in the United States, ensuring that employees can pursue union activities without fear of retaliation or discrimination from their employers.

In contrast, the Fair Labor Standards Act primarily focuses on wage and hour regulations, the Equal Employment Opportunity Act addresses discrimination in the workplace, and the Family and Medical Leave Act provides eligible employees with job-protected leave for family and medical reasons. While all these acts play crucial roles in safeguarding workers' rights, the NLRA specifically targets the right to unionize, making it the correct choice for this question.
