SEIU 521 is a democratically-run, member-driven organization.

That means members govern and are at the heart of every decision in our union. At the head of our member-driven governance is our union’s Executive Board. Members elect the officers, executive board delegates, and trustees from among their fellow union members, every three years. Guided by SEIU International Constitution & Bylaws, they make decisions about our union’s budget, policies, and other organizational issues. The officers and board members are active union members representing every division in our union.

SEIU 521 represents 40,000 county, city, and non-profit workers in 17 counties grouped into five regions:

  • Region 1: San Mateo & Santa Clara Counties
  • Region 2: Santa Cruz, Monterey, San Benito Counties
  • Region 3: Stanislaus, Tuolumne, Mariposa, Mono, Alpine, Merced Counties
  • Region 4: Madera & Fresno Counties
  • Region 5: Tulare, Kings, Kern, Inyo Counties

In addition, Family Child Care Providers are joining our union in all these regions, as well as in Alameda County.
