Public sector unions play a vital role in politics by advocating for workers' rights and influencing labor-related legislation. They represent the interests of employees working in government sectors, negotiating for better wages, working conditions, and benefits. These unions engage in collective bargaining and serve as a political voice for public sector employees, often participating in campaigns or lobbying for policies that support their members. Additionally, they contribute to broader discussions on social justice and equity in the workplace, shaping the regulatory environment that governs labor practices.
