What SEIU Local 221 does

SEIU Local 221 is a nonprofit labor union organized under California law and affiliated with the Service Employees International Union (SEIU), the largest public-services union in the United States. The local represents 12,000+ workers across San Diego and Imperial counties, with the County of San Diego alone accounting for 10,000+ members spanning librarians, social workers, public health nurses, animal control officers, 911 dispatchers, and detention health staff. Additional bargaining units cover municipal employees (City of National City), school district workers (Grossmont Union High School District), Head Start program staff at non-profits such as MAAC Project and Neighborhood House Association, clinical staff at American Red Cross Southern California Blood Services, and San Diego Superior Court reporters and Family Court Counselors.

The union's product surface is service-based rather than technology-based. Core offerings include collective bargaining representation, the Advocacy Center for grievance handling and pre-disciplinary hearings ((858) 268-7020), steward training, the Member Political Organizer (MPO) committee for candidate endorsements, a Strike Fund, the SEIU Classification Calculator (calculator.seiu221.org), member benefits/discounts, affinity groups, and retiree membership. Annual operating revenue is generated exclusively from member dues set by SEIU International convention delegates and billed monthly; specific dues amounts are not publicly disclosed.

Distribution follows a community-led go-to-market model anchored by worksite stewards, Contract Action Teams, political organizer committees, and a physical union hall at 4004 Kearny Mesa Road in San Diego. Outreach supplements this field infrastructure with social media channels (Facebook, Twitter/X, Instagram), rallies, press conferences, and partnerships with the San Diego and Imperial Counties Labor Council, Center on Policy Initiatives, Alliance San Diego, PICO California, and Catholic Charities San Diego. Notable recent wins include the 2022-2025 County of San Diego contract (3%/3.5%/3% base wage increases plus equity adjustments, ratified June 18, 2025) and the qualification of the San Diego County Health & Safety Act for the November 2026 ballot following 121,000+ verified signatures.
