Labor unions play a critical role in politics by advocating for workers' rights and interests. They organize collective bargaining efforts, pushing for fair wages, safer working conditions, and benefits for their members. Unions also engage in political lobbying, influencing legislation regarding labor laws and policies. By mobilizing their membership for political action and endorsements, they can significantly impact elections and hold elected officials accountable on workplace issues. Additionally, unions contribute to broader social movements, advocating for progressive policies such as healthcare reform and income equality, which resonate beyond their immediate membership.
