What is the primary role of labor unions within the labor market?

The primary role of labor unions within the labor market is to mediate disputes between employees and management. Labor unions are organizations that represent the collective interests of workers. They advocate for workers' rights, provide support during conflicts over pay, working conditions, or other employment issues, and negotiate on behalf of their members with employers.

This mediation process often involves collective bargaining, where unions negotiate contracts that set terms of employment, which may include wages, benefits, and working conditions. By serving as a collective voice for workers, unions can effectively address grievances and ensure that employee concerns are heard and addressed within the workplace.

The other options do not accurately capture the main function of labor unions. While unions may provide support in hiring processes or have some influence over wages, their key role is centered around negotiation and dispute resolution. Unions do not have the ability to eliminate unemployment across all sectors, as this is influenced by broader economic factors. Additionally, they regulate wages specifically for their union members, not for all types of jobs across the labor market.
