WARN notices and layoff law in South Dakota
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; the South Dakota Department of Labor and Regulation states on its own WARN page that the state adds no requirements beyond the federal ones. You can see mass layoffs reported in South Dakota on the state's official WARN list at dlr.sd.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.
South Dakota WARN FAQ
How much notice must an employer give before a layoff in South Dakota?
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. South Dakota 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 South Dakota?
South Dakota publishes filed WARN notices on its official state workforce site at dlr.sd.gov. It lists employers, locations, and dates of reported mass layoffs and closings.
Does South Dakota have its own layoff-notice law beyond federal WARN?
No. South Dakota 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.
