54 California counties with WARN notices since 2014
Ordered by workers affected. Counties are as reported to the EDD; 2014 to 2017 filings carried only a city, so the county for those is assigned from the city.

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.
