WARN notices and layoff law in New Hampshire
The federal WARN Act covers employers with 100 or more full-time employees. It requires 60 calendar days' written notice before a plant closing that costs 50 or more full-time workers their jobs at one site, or a mass layoff at one site within 30 days of either 500 or more full-time workers, or 50 to 499 who make up at least a third of that site's workforce. New Hampshire adds its own protection: New Hampshire (RSA 282-A:45-a) requires employers to report any mass layoff of 25 or more workers in the same week to NH Employment Security, a lower threshold than the federal WARN Act's 100-employee/60-day rule. New Hampshire does not post a public WARN list online; its agency WARN page is at www.nheconomy.com.
