Descriptiontext

SEIU-UHW (Service Employees International Union – United Healthcare Workers West, Local 2005) is a private, member-governed labor union representing more than 120,000 healthcare workers, patients, and healthcare consumers across California. Its members include frontline respiratory therapists, dietary and environmental-services staff, nursing personnel, and other employees working primarily at the state's largest private-sector hospital systems — notably Kaiser Permanente, Dignity Health, Sutter Health, Tenet Healthcare, Prime Healthcare, and Sharp HealthCare. The organization is an affiliate of the two-million-member Service Employees International Union (SEIU International) and operates within the SEIU California State Council, which coordinates strategy across 700,000+ California workers.

The union's core product is collective bargaining and workplace representation, delivered through a network of elected union stewards embedded at worksites and supported by staff representatives. Members access services through the MyUHW member portal — a secure iOS mobile application and web platform providing personalized access to their union contract, representatives, and resources. Adjacent products include downloadable contract documents (notably the Kaiser 'Purple Book'), Know Your Contract educational resources, Weingarten Rights legal guidance, Emotional Wellness programs, Financial Wellness workshops (delivered with the International Rescue Committee, HERA, and SCE Credit Union), and healthcare-education pathways operated with Calbright College, AlliedUP Co-op, Futuro Health, and The Ed Fund.

Revenue is generated almost entirely through member union dues set at 2% of base pay (excluding overtime and shift differentials), with no dues collected until a member ratifies their first contract and any dues increase requiring a secret-ballot vote of all members. SEIU-UHW distributes services through a combination of direct worksite representation, a statewide office network (Oakland HQ plus Los Angeles, Fresno, Sacramento, San Jose, and San Diego), and digital self-service via the MyUHW portal. Growth is driven by community-led organizing campaigns at non-union healthcare facilities, which since 2023 have added more than 8,500 new members including 6,000+ at Sharp HealthCare, 1,500+ at Rady Children's Hospital, 550+ at Planned Parenthood, and 400+ at dialysis operators Fresenius and Satellite Healthcare.

Wealth ManagementCalifornia Union Leader Pushes Billionaire Wealth TaxDave Regan, head of SEIU-UHW, is campaigning for California's Proposition 40, a billionaire wealth tax, to offset roughly $100 billion in federal healthcare funding cuts.

The California initiative, supported by the SEIU-UHW union and opposed by Governor Gavin Newsom, faces significant opposition funded largely by Google co-founder Sergey Brin through competing ballot initiatives.

This significant financial push by opponents contrasts with support from SEIU-UHW and has led prediction markets to lower the likelihood of the measure's passage to 27.5%. The campaign is expected to intensify as voters decide on this high-stakes fiscal initiative.
