A labor union, also known as a trade union, is an organization formed by workers in a particular trade, industry, or company for the purpose of improving pay, benefits, and working conditions. Unions may organize a particular section of skilled or unskilled workers, a cross-section of workers from various trades, or attempt to organize all workers within a particular industry. The agreements negotiated by a union are binding on the rank-and-file members and the employer, and in some cases on other non-member workers.

Labor unions work like democracies, with local chapters that obtain a charter from the national-level organization. Union members democratically elect their leaders who are then responsible for advocating for the good of the unit. Unions enable workers to negotiate for higher wages and benefits and improve conditions in the workplace. Union contracts specify workers’ pay, hours, benefits, and job health and safety policies.

In the United States, employers are required by law to actively bargain with a union in good faith, although they are not required to agree to any specific terms. The aim of labor unions is to ensure fair wages, benefits, and working conditions for union members.

Overall, labor unions represent the collective interests of workers, bargaining with employers over concerns such as wages and working conditions. By joining together in unions, workers can accomplish more than they could on their own.
