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.
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.
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.
