Layoff notices (WARN) › About this data
Layoff notices (WARN)
Under the federal WARN Act, an employer with 100 or more workers must give 60 days' notice before a mass layoff or a plant closing, and many states publish those notices. We collect them from twelve states and match the employer to a public company when the name lines up. About one notice in ten matches a public company, so the page starts with those; switch Employers to see all of them.
- Where it comes from
Each state's labor department publishes its own list. We collect them from twelve states.
Who reports it: The employer, to its state labor department, which publishes the list. Each state has its own format and its own timing.

- Coverage
- Twelve states. How far back each list goes, and how soon notices appear, differs by state.
- Worth knowing
- Not every layoff comes with a notice: smaller cuts, employers under the size threshold, and states we do not collect are missing. A notice is advance warning, so the layoff can end up smaller, later or called off. California lists a notice for several sites as separate lines, which we add together. We match employer names to companies automatically, so a subsidiary can be missed and a similar name can be matched wrongly. Notices dated in the future are left out, and effective dates that are clearly typing errors are left blank.
