Union leaders are individuals who represent the interests of workers in a labor union. They negotiate with employers on behalf of union members to secure better wages, benefits, and working conditions. Union leaders often organize strikes and other collective actions to advocate for workers' rights and ensure that their voices are heard in the workplace. These leaders are typically elected by union members and play a crucial role in maintaining communication between workers and management. They also provide support and resources for members, helping them understand their rights and responsibilities under labor laws and union agreements.
