WARN Act by State: Who Files, Who Doesn't, and the Gaps

The Federal WARN Act States with Most Filings States with Mini-WARN Laws Where the Gaps Are Enforcement Challenges How to Track Your State FAQThe Federal WARN Act
The Worker Adjustment and Retraining Notification (WARN) Act is a federal law that requires employers with 100+ employees to give 60 days' notice before mass layoffs or plant closings. It applies in all 50 states and the District of Columbia.
But "applies" and "is effectively enforced and tracked" are two very different things. The federal WARN Act has no central database. Each state's Department of Labor maintains its own records, with wildly different levels of accessibility and completeness.
States with the Most WARN Filings
Unsurprisingly, the most populous states with the largest economies produce the most WARN filings:
| State | Filing Volume | Mini-WARN? | Notice Period | Threshold |
|---|---|---|---|---|
| California | Very High | Yes | 60 days | 75 employees |
| New York | Very High | Yes | 90 days | 50 employees |
| Texas | High | No | 60 days (federal) | 100 employees |
| Illinois | High | Yes | 60 days | 75 employees |
| New Jersey | High | Yes | 90 days | 100 employees |
| Florida | Moderate | No | 60 days (federal) | 100 employees |
| Washington | Moderate | No | 60 days (federal) | 100 employees |
| Pennsylvania | Moderate | No | 60 days (federal) | 100 employees |
States with Mini-WARN Laws
About 15 states have enacted their own WARN-like laws that go beyond federal requirements. The most notable:
California (Cal-WARN)
California's WARN Act covers employers with just 75 employees (vs. federal 100). It also applies to relocations of 100+ miles. California WARN filings are the most comprehensive in the country because the lower threshold captures more events.
New York (NY WARN)
New York has one of the strictest WARN laws: 90 days' notice (vs. federal 60) and a threshold of just 50 employees. The state also requires employers to pay a $500/employee penalty for each day of violation.
New Jersey (NJ WARN)
New Jersey's WARN Act requires 90 days' notice and mandates severance pay of one week per year of service if notice isn't given. This is the strongest financial penalty of any state WARN law.
Illinois
Illinois covers employers with 75+ employees and requires notice to the Department of Commerce. The state maintains a well-organized public database of filings.

Where the Gaps Are
The biggest problem with the WARN Act isn't the law itself - it's the gaps in coverage and enforcement:
- 100-employee threshold is too high. The federal WARN Act only applies to employers with 100+ workers. A company with 99 employees can lay off everyone with zero notice. States without mini-WARN laws leave these workers unprotected.
- Remote workers create jurisdictional confusion. If a company's HQ is in California but workers are remote in Texas, which state's WARN rules apply? The answer is often unclear.
- "Unforeseeable circumstances" exception is overused. Employers frequently claim layoffs were unforeseeable to justify giving less than 60 days' notice. Courts are inconsistent in how they evaluate these claims.
- No central database. There's no federal repository for WARN notices. Each state maintains its own system. Some states publish filings online; others require FOIA requests. This is why we built JobRisk.io's WARN Alerts feed.
Enforcement Challenges
The WARN Act has no government enforcement mechanism. There's no federal agency that monitors compliance or imposes penalties. Workers must file private lawsuits to enforce the law - a significant barrier when you've just lost your job.
The practical result: some companies simply don't file when they should. They calculate that the risk of a lawsuit is lower than the cost of giving advance notice. Workers in states without strong mini-WARN laws have limited recourse.
