With 2.2 million members in the United States, Canada and Puerto Rico, the Service Employees International Union (SEIU) is the fastest-growing union in the Americas. Focused on uniting workers in healthcare, public services and property services, SEIU members are winning better wages, healthcare and more secure jobs for our communities, while uniting their strength with their counterparts around the world to help ensure that workers — not just corporations and CEOs — benefit from today's global economy.
