The federal Worker Adjustment and Retraining Notification Act requires larger employers to give workers advance notice before certain plant closings and mass layoffs — generally 60 days. Several states add their own mini-WARN laws that can cover smaller employers, smaller layoffs, or longer notice periods. Always check the state source filing for the rule that applied to a specific case.
Notice date — when the filing was published. Effective date — when the layoff is scheduled to take effect. Workers — the headcount stated in the filing, which may cover one site or several. Type — for example permanent layoff, closure, or reduction in force, as stated by the filer.
Check the effective date first, then your state's unemployment and rapid-response resources, and keep a copy of any notice you received personally — the public filing is not a substitute for your individual notice.
