Risk Assessment
Understanding WARN Act Coverage
The federal WARN Act covers employers with 100 or more employees who are planning a plant closing or mass layoff affecting 50 or more workers. Companies below this threshold are not required to file WARN notices, though some states have lower thresholds under "mini-WARN" laws.
Even if your employer is WARN-exempt, checking industry trends can help you assess whether your sector is experiencing elevated layoff activity. Our database tracks all publicly available WARN filings across the United States.
Layoff Risk by Company Size
| Size | WARN Coverage | Risk Level |
|---|---|---|
| Under 100 | Exempt | Variable (no public filing required) |
| 100-499 | Covered | Moderate — fewer mass events but higher relative impact |
| 500-4,999 | Covered | Elevated — frequent restructuring events |
| 5,000+ | Covered | Highest — most WARN filings come from large employers |
