One of California’s most influential labor unions, the Service Employees International Union (SEIU) California, has opted for a neutral stance on a proposed state ballot measure that would levy a one-time tax on the wealthiest residents, a decision that represents a significant blow to the initiative’s proponents and underscores developing fissures within the state’s progressive coalition. The executive board’s vote on Wednesday effectively sidelines a key endorsement for Proposition 40, a measure slated for the November ballot.
Proposition 40 proposes to impose a 5% tax on the net worth of billionaires who were California residents as of January 1, 2026. The measure’s architects, primarily SEIU-United Healthcare Workers West (SEIU-UHW), a powerful affiliate of SEIU California, had hoped for widespread backing from the state’s organized labor movement. However, the broader SEIU California’s decision to abstain from endorsing highlights a complex interplay of priorities and concerns among different labor factions and their allies.
H2: SEIU California’s Neutrality and Stated Reasoning
In a statement released following the executive board’s decision, SEIU California, representing 750,000 members across various sectors, acknowledged the proposal’s intent to generate revenue for healthcare. "The one-time tax proposal is dedicated 90% to healthcare," the union stated, echoing concerns voiced by other labor organizations that have expressed opposition to Proposition 40. These opposing unions, including those representing teachers, police officers, and firefighters, argue that the measure’s primary beneficiary would be the healthcare sector. Their apprehension stems from fears that such a targeted, one-time tax could destabilize the state budget in the long term, potentially jeopardizing funding for essential public services like education and public safety.
The strategic maneuvering surrounding Proposition 40 has also brought to light internal dynamics within the SEIU umbrella. SEIU-UHW, the driving force behind the ballot initiative, brought the measure forward with the aim of addressing what its leaders describe as a critical funding shortfall. SEIU-UHW President Dave Regan has publicly stated that the tax is intended to backfill an estimated $100 billion in projected cuts to healthcare and food assistance programs. These anticipated reductions are attributed by Regan and his union to the "One Big Beautiful Bill Act," a piece of federal legislation signed by President Trump last year, which they contend disproportionately impacted California’s social safety net to fund tax breaks for the wealthy.
Renee Saldana, SEIU-UHW’s Press Secretary, articulated this perspective forcefully in a statement to the Los Angeles Times. "Trump’s ‘Big, Ugly Bill’ slashed funding for healthcare in California to pay for more billionaire tax breaks. Now, millions of Californians are losing their health coverage, and millions more are being forced to pay skyrocketing costs," Saldana stated. She further cited an internal poll suggesting that 70% of SEIU members in California support the billionaire tax, expressing confidence that "SEIU members will be joining millions of their fellow Californians and voting YES on Prop. 40 this November to protect healthcare, keep hospitals and clinics open, and stand with California working families."
H2: Political Negotiations and Broader Concerns
The decision by SEIU California to remain neutral comes amidst a backdrop of significant political negotiation and broader concerns about the state’s fiscal future. Reports suggest that Dave Regan, in discussions with Governor Gavin Newsom last month, had offered to withdraw Proposition 40 from the ballot in exchange for concessions beneficial to his union, including assistance in securing contracts at several medical facilities statewide. Regan has denied making such demands, maintaining that the proposal’s sole purpose is to address an impending "catastrophe in California’s healthcare system."
However, the concerns about the measure’s impact extend beyond the immediate fiscal implications for healthcare. Several other unions and prominent Democratic allies, including the Planned Parenthood Affiliates of California, have voiced reservations, arguing that a one-time tax is an insufficient and potentially problematic solution to funding gaps that may persist as long as Republicans control federal legislative power. Their argument centers on the unpredictability of revenue generated by a single tax event and the potential for unintended consequences on the state’s broader economic stability.
SEIU California’s broader strategic focus appears to be on a "multi-year campaign to secure California’s fiscal foundation with ongoing revenue." This includes efforts to implement measures such as taxing large corporations whose low wage practices necessitate that their employees rely on public benefits. This approach suggests a preference for sustained, systemic revenue generation rather than a one-off tax event.
Governor Newsom himself has recently taken a stance that indirectly addresses some of these revenue concerns. This month, he postponed a decision on the "Fair Share" measure, which aims to tax large companies for not paying adequate wages, pushing its consideration to next year, when a new governor will be in office. This decision, made in the presence of SEIU California executive board members, signals a cautious approach to significant fiscal policy shifts.
H3: The Specter of Wealth Exodus and Policy Debate
A significant point of contention among labor unions and Democratic policymakers is the potential for a wealthy exodus from California in response to a billionaire tax. Critics argue that a tax targeting high-net-worth individuals could incentivize them to relocate to states with more favorable tax regimes, ultimately diminishing California’s tax base. This concern is particularly acute given the state’s existing reliance on higher income tax rates from its wealthiest residents to fund public services.
The phenomenon of wealthy individuals preemptively seeking to avoid potential taxation is already evident. Sergey Brin, co-founder of Google, reportedly moved to the Nevada side of Lake Tahoe last year, a move widely interpreted as a strategy to circumvent future wealth taxes. Brin has since contributed $82 million to a committee actively campaigning against Proposition 40, underscoring the significant financial opposition the measure faces.
Governor Newsom has publicly advocated for a federal wealth tax as a more effective and equitable solution. In a recent Substack post, he argued, "You may not be able to pick up and move to Texas or Florida to shelter your income from taxation, but I promise you that billionaires can, and do. The fight belongs at the federal level, where this broken system was created in the first place." Newsom’s focus on federal action reflects a broader debate about the efficacy of state-level wealth taxation versus a coordinated national approach.
H3: Broader Ballot Landscape and SEIU California’s Stance
The SEIU California executive board’s decision on Proposition 40 is not an isolated event. On the same day, the union announced its strong opposition to two other ballot measures: Proposition 39, a voter ID initiative, and Proposition 43, which seeks to make it more difficult for local governments to raise taxes. This multifaceted stance on the November ballot reflects SEIU California’s engagement with a range of policy issues that impact its members and the broader Californian populace.
The divergence of opinion within the progressive movement on Proposition 40, particularly the neutrality of a powerful umbrella organization like SEIU California, highlights the complexities of crafting consensus on ambitious fiscal policies. While SEIU-UHW remains a staunch advocate, the broader union federation’s position suggests that the path to enacting a wealth tax in California, even one championed by a significant labor entity, is fraught with challenges and necessitates navigating a diverse set of interests and concerns. The debate over Proposition 40 is likely to continue, with its outcome potentially shaping future discussions on progressive taxation and revenue generation in the Golden State.
