The Service Employees International Union (SEIU) is a dynamic and influential labor union representing approximately 2 million members across a wide range of occupations in the United States, Canada, and Puerto Rico. Members work in healthcare (hospitals, nursing homes, home care), public services (local and state government, schools), and property services (janitors, security officers). SEIU is committed to organizing workers to fight for better wages, comprehensive healthcare, secure retirement, and improved working conditions. The union actively engages in political advocacy, community organizing, and collective bargaining to advance social and economic justice for all working families.
Serves as the primary administrative, strategic planning, and advocacy hub for the international union, coordinating national campaigns, policy efforts, and support for local unions.
Modern office building in a prominent D.C. location, designed to facilitate collaboration and host significant labor movement events.
Mission-driven, collaborative, and fast-paced, focused on advocacy, member empowerment, and social justice. Staff are typically passionate about labor rights and progressive causes.
The headquarters is a symbol of the union's national presence and influence, serving as a critical center for decision-making, policy development, and mobilization on issues affecting working families.
While primarily focused on organizing and representing workers in the United States, Canada, and Puerto Rico, SEIU actively participates in global labor solidarity. It is affiliated with global union federations such as Public Services International (PSI) and UNI Global Union. Through these affiliations, SEIU collaborates on international campaigns, supports workers' rights movements globally, shares organizing strategies, and addresses the challenges posed by multinational corporations, particularly in the healthcare, property services, and public sectors.
