Who We Are

Service Employees International Union, Local 521 represents 40,000 public- and nonprofit, private-sector workers in the central Bay Area region and in the Central Valley. Under a Community First vision, we are committed to making sure the needs of our community, and the vital services we provide our community, come first. We believe our communities thrive when residents, leaders and workers recognize that we are all in this together when it comes to our safety, health, and well-being.

SEIU Local 521 is part of The Service Employees International Union, an organization of 2 million members united by the belief in the dignity and worth of workers and the services they provide. SEIU is dedicated to improving the lives of workers and their families and creating a more just and humane society. Learn more about SEIU International.

Our local is also part of SEIU, California State Council.


Five SEIU locals came together to cover the Central Region of California by forming one larger, more powerful local – SEIU Local 521. We received our charter as a new individual local on Jan. 2, 2007, and combined all the resources of the five former locals on March 1, 2007. This marked a new beginning for workers. We are stronger together.
