Trade unions play a critical role in influencing political policies and advocating for labor rights. They represent workers' interests, lobbying for fair wage laws, workplace safety, and social protections. By negotiating collective bargaining agreements, unions set standards that affect legislation and public policy, pushing governments to adopt pro-labor regulations. Furthermore, unions engage in political campaigns, supporting candidates who align with their goals. Their activism fosters a collaborative environment between workers and legislators, promoting the overall welfare of the labor force and ensuring that labor rights are upheld.
