Local help after a layoff in Pomona
A WARN notice is the start of a paper trail, not the end of your rights. Workers in Pomona bring WARN back-pay claims in the Superior Court of the county, and the agency routes for the questions that usually travel with a layoff are the same statewide: unpaid final wages and vacation payout go to the Labor Commissioner, discrimination in who was selected goes to the Civil Rights Department (three years to file) or the EEOC (300 days). Our Pomona employment law page covers the local courts, agencies and deadlines. See also all notices in the county. Free, confidential review: (800) 371-3088.
Source: California EDD WARN reports, July 2014 to Oct 27, 2026. County and city are as stated on the notice; for 2014 to 2017 filings, where the EDD listed only a city, the county is assigned from that city. Back to the layoff tracker.
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.
