Timeline for California State Legislature
Advanced SB 951 and SB 947 through Assembly committee stage
AI: Jobs, Power & Money: California bill sets 90-day AI layoff notice- What AI employment laws is California passing in 2026?
- California's Legislature is advancing SB 951 (requiring 90 days' advance notice for AI-driven mass layoffs) and SB 947 (worker protections for AI-assisted employment decisions), both having passed the Senate and advancing through the Assembly as of June 2026.Source: California State Legislature
- How does the California effect work for AI regulation?
- Because California is the world's fifth-largest economy, businesses operating across multiple US states often adopt California-compliant standards universally rather than maintain separate compliance stacks — meaning California AI labour laws can set de facto national floors even without federal legislation.
- Can the Trump administration stop California's AI worker protection laws?
- The Trump administration's National Policy Framework directs federal agencies to preempt state AI labour laws. Colorado's AI Act was stayed by a federal court in April 2026 following a DOJ challenge. California's laws face the same constitutional risk if enacted.
- Does California's governor have to sign AI employment bills that the legislature passes?
- No. The governor retains veto power. Governor Newsom vetoed a 2024 AI safety bill on industry-impact grounds, demonstrating that Democratic supermajority passage does not guarantee enactment for AI regulation in California.
Background
The California State Legislature is the bicameral legislature of the State of California, comprising the 80-member State Assembly and the 40-member Senate. As the legislature of the world's fifth-largest economy, its enactments routinely become de facto national standards: the California effect, whereby compliance costs push multi-state businesses to adopt California rules uniformly, operates in technology, environment, and labour markets alike. In 2026 the Legislature has become the primary US venue for AI employment regulation, with SB 951 (90-day AI layoff notice), SB 947 (AI worker protections), and related measures advancing simultaneously through the Assembly after Senate passage.
The Legislature meets in Sacramento and operates on a two-year session cycle. Bills originating in one chamber must pass the other in the same two-year session or lapse. The Assembly is the lower chamber; the Senate sits as the upper. Both chambers are controlled by Democratic supermajorities as of 2026, meaning the primary brake on AI labour bills is the governor's veto pen and legal challenges from the Trump administration rather than internal legislative opposition. The governor cannot be compelled to sign any bill, and Governor Newsom has previously vetoed AI regulation bills (including a 2024 AI safety bill) on industry-impact grounds, making the final stage of any AI employment bill uncertain.
California's legislature holds disproportionate influence in US labour law because of its size, Democratic alignment, and willingness to act ahead of federal inaction. The WARN Act extension model it is piloting with SB 951, and the worker-protections framework of SB 947, are being watched by legislators in New York, Illinois, and Washington State. Simultaneously, the Trump administration's National Policy Framework explicitly targets state AI labour laws for federal preemption, placing California's 2026 legislative agenda at the centre of a constitutional conflict over who governs AI and employment in the United States.
