Labor unions are organizations formed by workers to protect their rights and interests in the workplace. They negotiate with employers on behalf of their members to secure better wages, benefits, and working conditions. By coming together, workers can have a stronger voice in discussions about their jobs. Unions also provide support and resources for their members, including legal assistance and training programs. They play a crucial role in advocating for labor laws and policies that benefit all workers, not just those who are union members. Examples of labor unions include the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) and the Service Employees International Union (SEIU).
