WARN Act and Layoffs at Startups: Why Most Startup Layoffs Come With No Notice

Startup layoffs are a regular feature of the tech news cycle, yet they almost never show up in WARN data. The reason is simple arithmetic: the WARN Act only applies to employers with 100 or more full-time employees, and most startups never reach that size. A 40-person startup can lay off its entire staff with no WARN notice at all — legally.

That gap shapes everything about how a startup layoff feels. There is usually no 60-day notice period, no formal filing with the state, and no public record. Workers find out in a meeting, a video call, or a Slack message, and their last day is often that same week.

The threshold is the whole story

Federal WARN covers employers with 100 or more full-time employees. A plant closing or mass layoff then triggers 60 days' notice. Below 100 employees, the federal law simply does not apply — it does not matter how many people are cut, or how suddenly.

State mini-WARN laws lower the bar in some places, and that matters because startups cluster in states that have them. California's Cal-WARN applies at 75 employees, counting part-time workers. New York's law applies at 50 full-time employees and requires 90 days' notice. Illinois applies at 75 full-time employees. New Jersey requires 90 days' notice and severance. Wisconsin's law can apply to employers with 50 or more workers when 25 are affected. Iowa's applies at just 25 employees, with 30 days' notice. Maine's applies at 100 employees but requires 90 days' notice and severance.

Even so, a startup with 30 or 50 people is below every one of those thresholds except Iowa's. For the typical early-stage company, no notice law applies at all.

What the data shows — and hides

The national WARN picture right now is 667 notices covering 61,284 reported workers in the 90-day window, with California leading at 22,043 reported workers. But those numbers describe larger employers: in 2026, California has logged 1,275 notices covering 69,857 workers, and the filings that make the news — ServiceNow's 62-worker California filings, Blue Shield's 54 workers across eight sites — come from companies big enough to trip the thresholds.

The startup layoffs that do not appear in the data are invisible by design. WARN coverage is not a census of layoffs, and the undercount is worst exactly where employment is most precarious: small, young companies. A startup that cuts 30 of 45 people has laid off two-thirds of its workforce, and no WARN notice will ever be filed.

Three rules that can still catch a startup

There are exceptions worth knowing. First, the 90-day aggregation rule: layoffs spread across 90 days count together, so a startup that cuts 20 people in January and 40 more in March may cross a threshold it thought it had avoided. Second, the single-site rule: employees spread across offices can count as one site if the locations operate together, which matters for startups with a headquarters plus a small satellite office. Third, the parent-company question: a startup owned by a larger company, or operating as part of a group, may count toward the parent's headcount depending on how the businesses are structured.

None of these helps a worker at a genuinely small, independent startup. But they are worth checking before assuming no law applies — especially after an acquisition, when a startup suddenly becomes part of a much larger employer.

The equity trap

Startup pay is often part equity, and equity is where a sudden layoff hurts most. Stock options usually stop vesting on your last day, and the standard window to exercise vested options is 90 days after leaving — after which they expire worthless. If your options are underwater, that may not matter; if the company later succeeds, it can matter a great deal. Check your grant agreement before your last day, and find out whether your options are incentive stock options or non-qualified options, because the tax treatment differs.

Severance at startups is also uneven. There is no law requiring it, and early-stage companies often offer little or none — a week or two per year of service is common, and some offer nothing. Whatever is offered usually comes with a separation agreement that includes a release of claims. Read it before signing, and remember that severance terms can sometimes be negotiated, particularly around the exercise window for options and continued health coverage.

What startup workers can do now

First, know your employer's headcount and your state's threshold — that tells you whether any notice law applies to you at all. Second, keep copies of your offer letter, equity grant, and any layoff communications off company devices. Third, if a layoff is announced, ask in writing how many people are affected and whether the company considered WARN — the answer may reveal whether the 90-day aggregation rule or a parent company changes the picture. Fourth, file for unemployment right away and contact your state's Rapid Response team, which can help even when no WARN notice was filed.

These are reported plans, not confirmed job losses. Figures describe WARN notices filed with state agencies, and the startup layoffs missing from the registry are a reminder of what the data cannot show.
