Truck driver unions are organizations that represent the interests of truck drivers and other transportation workers. They advocate for better working conditions, fair wages, and benefits such as health insurance and retirement plans. By joining a union, truck drivers can collectively negotiate with employers, which can lead to improved job security and workplace safety. These unions also provide support and resources for their members, including training programs and legal assistance. Notable unions in the trucking industry include the Teamsters and the United Transportation Union. Through collective bargaining, truck driver unions aim to ensure that workers' rights are protected and upheld.
