Which institutions have historically represented the rights of workers?

Labor unions have historically played a crucial role in representing the rights of workers. They are organizations formed by workers to advocate for their collective interests, including better wages, safe working conditions, job security, and other employment-related concerns. Unions negotiate collective bargaining agreements with employers, which outline the terms of employment for workers. Through strikes, negotiations, and political action, labor unions have significantly influenced labor laws and workplace standards, improving the overall conditions for workers.

In contrast, while employment agencies may assist with job placement, they do not primarily focus on advocating for workers' rights. Nonprofit organizations and government bodies can also support workers, but their roles are often broader and may not be exclusively dedicated to labor issues in the way that unions are. Therefore, labor unions stand out as the primary institutions historically associated with defending and promoting the rights and interests of the workforce.
