Trade unions play a significant role in politics by advocating for the rights and interests of workers. They engage in collective bargaining to negotiate wages, working conditions, and benefits, influencing labor laws and policies. Additionally, unions often endorse political candidates and mobilize their members to participate in elections, thereby shaping political agendas that benefit the workforce. Through lobbying and activism, trade unions contribute to broader dialogues on economic justice and workers' rights, making them key players in the political landscape.
