Local help after a layoff in San Mateo

A WARN notice is the start of a paper trail, not the end of your rights. Workers in San Mateo 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 San Mateo employment law page covers the local courts, agencies and deadlines. Free, confidential review: (800) 371-3088.
