WARN notices and layoff law in Colorado
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. Follows the federal WARN Act only for mass layoffs; separately, C.R.S. § 8-74-101(4) requires every separating employee in Colorado — laid off or not — to receive written notice of the reason for separation, on the state's Form 22-234. You can see mass layoffs reported in Colorado on the state's official WARN list at cdle.colorado.gov.

If notice is skipped
Back pay + benefits for the missing days, up to 60
If your employer skipped required WARN notice, you may be owed back pay and benefits for the missing days, up to 60. There are narrow exceptions (genuinely unforeseen circumstances, disasters), and most layoffs don't qualify.
This is general information, not legal advice. If you think you were owed notice, an employment attorney can tell you whether you have a claim, often with a free first consultation.
Colorado WARN FAQ
How much notice must an employer give before a layoff in Colorado?
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. Colorado follows the federal WARN Act only. If an employer skips required notice, it can owe back pay and benefits for the missing days.
Where can I see WARN notices filed in Colorado?
Colorado publishes filed WARN notices on its official state workforce site at cdle.colorado.gov. It lists employers, locations, and dates of reported mass layoffs and closings.
Does Colorado have its own layoff-notice law beyond federal WARN?
No. Colorado follows the federal WARN Act only, so notice is owed only when a layoff meets the federal thresholds (an employer of 100 or more, and a plant closing or mass layoff at one site). This is general information, not legal advice.
