WARNScan — WARN Act layoff and plant closure tracker
63,997 mass layoff and plant closure notices filed under the federal WARN Act, searchable by company and state, refreshed every single day.
Why layoff notices deserved a proper tracker
WARN filings are public by law, yet they live scattered across dozens of state agencies in wildly inconsistent formats. WARNScan, an own product I built and operate, pulls those filings together, normalises them and publishes them as one daily-updated tracker of mass layoffs and plant closures across America.
The audiences are surprisingly varied: workers checking whether their employer has filed, reporters covering a tech layoff wave, labor-market analysts watching volume trends, and HR or finance teams keeping an eye on their industry.
What the tracker does
- Layoff Checker. Look up any employer by name and instantly see its WARN filing history.
- Trending notices. The highest-impact current filings — recent examples include Meta Platforms (1,395 affected), Samsung Electronics America and Microsoft.
- Recent notices feed. A daily table listing company, location, date, notice type and number of workers affected.
- Largest layoffs ranking. A dedicated view of the biggest filings in the database.
- State-by-state browsing. Coverage across 48 tracked states, each with its own listings.
- Stats section. Aggregate numbers that turn thousands of individual filings into a readable labor-market signal.
Numbers behind the tracker
Every filing keeps its core fields — employer, location, date, affected headcount — and feeds the rankings and stats pages. The tracker is live right now: Visit warnscan.com.
The build
Ingesting filings from dozens of state sources every day takes a robust pipeline: a custom Laravel + PHP backend, a MySQL database optimised for tens of thousands of filings and pages, and programmatically generated company, state and ranking views. No off-the-shelf theme, no plugins.
Programmatic SEO does the distribution work: every employer and state gets an indexable URL, so a search for a company name plus the word layoffs can land straight on its filing history.
Common questions
What exactly is a WARN notice?
Under the federal Worker Adjustment and Retraining Notification Act, US employers must give advance notice before mass layoffs and plant closures. Each filing is public — WARNScan aggregates those filings from state sources into one searchable tracker.
How fresh is the data on WARNScan?
Notices are updated daily. Trending and recent sections surface the latest filings — from a 1,395-employee Meta Platforms notice to filings by Samsung and Microsoft — as they land.
How much of the US does the tracker cover?
It tracks 48 states and currently holds 63,997 notices filed by 37,799 companies. Every record carries the company name, location, filing date and the number of workers affected.
Can I check whether a specific employer filed a WARN notice?
Yes — that is what the Layoff Checker is for. Type a company name and see its WARN filing history, which is useful for employees, journalists, analysts and anyone doing due diligence on an employer.
