Adventist Health Simi Valley layoff notices at a glance
Adventist Health Simi Valley has filed 15 WARN notices with the California Employment Development Department between Jan 5, 2018 and Jun 25, 2026, naming 201 workers. 2 were closures and 13 were layoffs; 14 permanent, 1 temporary. The largest single notice named 70 workers in Ventura County on Jan 5, 2018. Its latest notice, 7 workers in Ventura County dated Jun 25, 2026, was 0.4% of the 1,732 workers named in all 25 Ventura County notices of fiscal year 2025-2026. 9 of the notices show fewer than 60 days between the notice date and the effective date (see how to read this). 1 notice carries a notice date later than the effective date it announces, which usually means the letter reached the EDD after the separations had begun. 3 fall in the March to June 2020 window when the Governor's COVID order suspended the 60-day requirement.

How to read this record
Notice date is the date on the employer's letter. Effective is the first day of separations it announced. Days notice is the gap between them; California Labor Code 1401 calls for 60 days from a covered employer, and section 1402 makes a short notice worth a day of pay and benefits for every day it is short, up to 60.
For Adventist Health Simi Valley the shortest gap shown is 0 days. That is a reason to check whether an exception in 1401(c) or 1402.5 applied, whether the workers received the letter earlier than the EDD did, and whether anyone was let go before the effective date. It is not, by itself, a finding against the employer.
One notice is dated after the effective date on the same filing. Notice given after the layoff has started is the clearest case the statute addresses: section 1402 counts every day between the separation and the notice as a day owed, up to 60.
One notice is marked temporary. A temporary layoff that runs past six months is treated as a termination under the federal Act, and the employer should issue a new notice before that point.
Full statute walk-through: the California 60-day rule, section by section.

About this data: Notices come from the California Employment Development Department WARN reports (fiscal years 2014-2015 to today) and are reloaded from the EDD every Tuesday and Thursday. Employer names appear as the employer wrote them on the notice, grouped where the names clearly refer to the same company. A notice is not a finding that any law was broken. This page is general information, not legal advice about your situation.
