Summary of Difference between federal and state regulations
California has more strict laws regarding plant closings or mass layoffs than the federal Worker Adjustment and Retraining Notification Act (WARN). In California, employers having 75 or more employees are required to provide 60 days’ advance notice of covered plant closings and mass layoffs, notify the affected workers or their representatives, and the appropriate governmental units.
Federal WARN does not preempt any other federal, state, or local law, or any employer/employee agreement that requires other notification or benefit. Rather, the rights provided by WARN supplement those provided by other federal, state, or local laws.
