Workers' unions are organizations formed by employees to advocate for their rights and interests in the workplace. They negotiate with employers on behalf of their members to secure better wages, benefits, and working conditions. Unions aim to give workers a collective voice, making it easier to address issues that affect their jobs. These unions often engage in collective bargaining, a process where representatives from the union and the employer discuss and agree on employment terms. Additionally, unions may provide support during disputes, offer training programs, and promote workplace safety, helping to ensure fair treatment for all workers involved.
