Which of the following best describes a key benefit of trade unions?

The key benefit of trade unions is best described as collective bargaining power for workers' rights. Trade unions are organizations that represent the interests of a group of workers. By coming together, members can collectively negotiate with employers on various aspects of employment, including wages, working conditions, benefits, and job security. This collective power helps to amplify their voice and influence compared to negotiating as individuals, leading to more favorable terms and conditions for all union members.

In contrast, individual wage negotiations for each member can lead to discrepancies and a lack of solidarity among workers, which is not the primary goal of trade unions. Reduced responsibilities for individual workers does not accurately capture the primary role of unions, which is to empower rather than diminish individual participation in the workforce. Lastly, while trade unions can advocate for job security, they cannot guarantee it, as job security is often subject to market conditions and employer decisions. Thus, the strength of trade unions lies in their ability to mobilize collective efforts to advocate for workers' rights through organized negotiation.
