Worker Adjustment and Retraining Act (WARN) Information for Employers

California WARN Act


What is a WARN?

A WARN is a layoff notice from an employer. These notices provide protection to employees, their families and their communities by requiring 60 days’ notice of layoffs or plant closings, giving employees time to look for other work, file for unemployment or take care of other items that could be affected by their employment status. The Act is applicable to employers that employ, or have employed in the preceding 12 months, 75 or more full-time or part-time workers.

When does an employer need to file a WARN?

In California, employers must file a WARN if there are any plant closures or layoffs that impact 50 or more workers within a 30-day period, regardless of the size of the company as a whole. Notification of layoffs and plant closures must occur at least 60 days in advance, or be subject to fines and worker compensation. Visit the Employment Development Department (EDD) WARN website for more detailed information regarding WARNs and a FAQ page for answers to common questions.

Employers should review both the Federal WARN law and the California WARN law for a full understanding of notification requirements.  

How does an employer file a WARN?

An employer must first notify employees of the upcoming layoff at least 60 days in advance of the layoff. Then, the employer must submit a WARN to the local Workforce Development Board, local elected officials (chief elected officials of the city and county governments in which the employer is located) and EDD.

If a layoff is occurring in San Diego County, an employer must provide notice to the San Diego Workforce Partnership, which is the local Workforce Development Board for the region. Notification or questions can be sent to the Workforce Partnership’s Business Services team at warns@workforce.org
