Organization of workers who unite to improve wages and working conditions?

An organization of workers that unites to improve wages and working conditions is typically referred to as a labor union. These groups advocate for the rights and interests of their members through collective bargaining, negotiating contracts with employers to secure better pay, benefits, and working conditions. Labor unions also engage in political activism to influence labor laws and policies that impact workers. By joining together, workers can amplify their voices and strengthen their negotiating power.
