Unions play a vital role in shaping labor policies by advocating for workers' rights, fair wages, and safe working conditions. They serve as collective bargaining agents, negotiating with employers on behalf of their members. Unions also engage in political lobbying to influence legislation related to labor standards, social justice, and economic issues, making them critical players in the broader political landscape. By organizing workers and raising awareness about labor issues, unions contribute to the development of policies that aim to protect and enhance the welfare of the workforce, thereby impacting economic equality.
