What this means for CA workers
Kaiser Foundation Hospitals has 43 recorded WARN filings covering 315 workers, most recently on Oct 13, 2025.
WARN Act filings only capture layoffs of 50+ workers at sites of 100+ employees, so smaller reductions, contractor non-renewals, and voluntary separations are not shown here.
With 43 separate WARN Act filings in this dataset, Kaiser Foundation Hospitals has one of the more extensive recorded layoff-notice histories, covering 315 workers from Jul 7, 2025 through Oct 13, 2025, and even that likely understates the real total (why). By total workers affected, Kaiser Foundation Hospitals ranks #67 of 630 tracked employers in CA. Among the 8 other Health Care & Social Assistance employers with recorded WARN filings, the median is 888 affected workers -- Kaiser Foundation Hospitals's 315 sits well below that group's typical scale. Every recorded filing was reported to CA's workforce agency, in the Health Care & Social Assistance sector -- a single-state footprint, unlike the multi-state pattern common among larger employers.
Averaging 7 workers per notice, Kaiser Foundation Hospitals's filings fall into a pattern that suggests targeted team or department cuts that still crossed the WARN reporting threshold. With 43 separate recorded filings, this is not an isolated event, the cadence of notices points to recurring workforce adjustment tied to industry cycles, merger integration, or capacity right-sizing.
Workers on CA-based Kaiser Foundation Hospitals notices should contact the CA workforce agency directly, response teams, severance negotiation guidance, and TAA (Trade Adjustment Assistance) screening move fastest in the days immediately following a notice. See what to do after a layoff for the full benefits timeline. This record reflects filed notices only; subsequent hiring, rescinded closures, or facility reopenings are not tracked by WARN disclosures.
Kaiser Foundation Hospitals has filed 43 WARN Act notices affecting 315 workers across 1 state. The most recent notice was filed on Oct 13, 2025.
According to WARN Act filings, Kaiser Foundation Hospitals has affected 315 workers total, averaging 7 workers per notice.

The Worker Adjustment and Retraining Notification (WARN) Act requires employers with 100+ employees to provide 60 days advance notice of plant closings and mass layoffs affecting 50 or more workers. Not all layoffs require WARN notice.
Workers affected by a WARN-notified layoff may be eligible for unemployment insurance, COBRA health coverage continuation, job retraining through the Trade Adjustment Assistance program, and severance packages if offered by the employer. State workforce agencies often provide additional rapid response services.
Kaiser Foundation Hospitals has affected 315 workers across 43 WARN filings in the Health Care & Social Assistance sector. The federal WARN Act only captures layoffs affecting 50 or more workers, so actual workforce changes may be larger.
