Automation-driven layoffs still trigger WARN Act 60-day notice rules, regardless of cause

The WARN Act requires 60 days' written notice based on headcount thresholds, not the reason for a layoff. An employer with 100 or more full-time staff must give notice for plant closings or mass layoffs of 50 or more workers, so job cuts from robots or AI systems are covered the same way. The law's narrow exceptions, such as unforeseeable business circumstances, typically do not apply to automation projects because they are planned and installed over months. Some state laws, including California's Cal-WARN and New York and New Jersey rules, are stricter, sometimes requiring notice for smaller employers or 90 days. The article also notes that layoffs spread across rounds within 90 days can be aggregated, and that notice enables access to retraining resources through state Rapid Response teams.
