Employers with one hundred or more employees must give sixty days notice of a plant closing or mass layoff meeting defined thresholds. Exceptions cover faltering companies, unforeseeable business circumstances, and natural disasters.
Remedies include back pay and benefits for the notice period.

Why it Matters?
Aggregation rules capture employment losses across a rolling ninety-day period, which means sequential smaller reductions may collectively trigger the notice obligation that each individually would not. That aggregation catches employers reducing headcount incrementally. State mini-WARN statutes frequently impose lower thresholds and longer notice periods, and several apply to employers well below the federal one hundred employee floor.
