California's SB 951, requiring 90 days' notice before AI-driven displacement of 25% or more of a workforce, cleared the state Senate 28-9 on Wednesday 20 May 2026 and advanced through the Assembly committee stage in the week ending 6 June1. Companion bill SB 947, addressing further worker protections on AI deployment, passed the Senate 29-9 the day before, on Tuesday 19 May, and is also moving through the Assembly.
The 90-day figure is the operative detail. It exceeds the federal Worker Adjustment and Retraining Notification (WARN) Act, which sets a 60-day floor for mass-layoff notice at employers of 100 or more. Because large companies run multistate operations and cannot easily apply different notice periods by location, the strictest state rule tends to become the de facto national standard. If SB 951 reaches the governor's desk and is signed, its 90-day clock would in practice govern AI-driven cuts well beyond California.
Oracle's offshore terminations and remote-reclassification tactics showed how the 60-day requirement can be sidestepped, with US WARN filings covering under 4% of its workforce cuts. California is also moving against the grain of Colorado, which retreated to a notice-only framework in May. The state-by-state divergence, tightening in Sacramento and loosening in Denver, is now the operative pattern in the absence of any federal AI-workforce law.
