What is the role of the National Labor Relations Board?

The National Labor Relations Board (NLRB) plays a crucial role in safeguarding the rights of private sector employees. This includes the right to organize, join labor unions, and engage in collective bargaining. The NLRB oversees and enforces the National Labor Relations Act, which is designed to ensure fair labor practices and protect workers from unfair labor actions by employers or unions. By facilitating the relationship between unions and employers, the NLRB helps maintain a balance of power in the workplace, ensuring that employees can freely exercise their rights without fear of retaliation or discrimination.

The other options do not align with the primary function of the NLRB. The board does not regulate public sector employment agreements, nor does it prevent unions from striking, which is a legitimate exercise of worker rights. Additionally, the NLRB is not focused on promoting employer interests but rather on upholding employees' rights to collectively advocate for their working conditions.
