Most Frequent WARN Layoff Events
Top 50 employers with the highest number of separate WARN Act layoff notification events.
What This Ranking Tells Us
While total workers affected shows the scale of layoffs, the number of separate WARN events shows the frequency. Employers with many distinct layoff events may be undergoing prolonged restructuring, have seasonal workforce patterns, or operate in volatile industries. Frequent WARN filings from the same employer over multiple years is a stronger signal of ongoing instability than a single large event.
Reading This Ranking in Context
This ranking of "most frequent warn layoff events" is computed directly from the underlying PlainEmployers dataset — no editorial cherry-picking, no paid placements. 50 employers currently qualify for this ranking based on our minimum-filing and minimum-record thresholds. At position one, Wells Fargo (IA) leads the list with a events of 226, a figure pulled directly from the most recent federal or state disclosure rather than corporate self-reporting. The underlying source — WARN Act notices filed with state agencies — is a legally mandated filing, which is why we treat it as the authoritative signal rather than survey data or crowd-sourced reviews.
While total workers affected shows the scale of layoffs, the number of separate WARN events shows the frequency. Employers with many distinct layoff events may be undergoing prolonged restructuring, have seasonal workforce patterns, or operate in volatile industries. Frequent WARN filings from the same employer over multiple years is a stronger signal of ongoing instability than a single large event. Across the 50 employers on this specific list, the median events sits at approximately 50, so a visitor comparing an individual employer's profile page against this ranking can quickly see whether they're near the top of the list, the middle, or just above the qualifying threshold. That context matters: a rank of 40 on a list of 50 means something very different from a rank of 40 on a list of 2,000, and the ranking page surfaces both the position and the value so readers can judge significance for themselves.
Every row links back to an individual employer profile with the full underlying records — H-1B filing dates and disclosed salaries by job title, OSHA DART rates with total injury counts, WARN Act notices with dates and affected headcount. That drill-down is deliberate: a ranking number in isolation doesn't tell a jobseeker, reporter, or compliance researcher what they need to know, but combined with the per-employer disclosure trail it becomes actionable. PlainEmployers re-runs these rankings on a recurring ETL schedule, so newly filed federal disclosures and state WARN notices update the leaderboard without manual intervention, and retired records fall off as they age beyond the relevance window. Cross-reference this ranking with the industry and metro pages to see whether the pattern is concentrated in specific sectors or geographies.

Frequently Asked Questions
Why do some employers have so many separate WARN events?
Multiple WARN events can indicate: multi-site operations where different facilities close at different times, phased layoffs spread over months, seasonal business patterns requiring periodic workforce reductions, or ongoing corporate restructuring. Companies in retail, hospitality, and manufacturing are more likely to file multiple WARN notices due to their distributed operations.
How far back does WARN data go?
WARN Act data availability varies by state. Most state agencies maintain records going back 5-10 years, though some have longer archives. Our database includes the most recent available data from state workforce agencies. Note that filing requirements and reporting practices can vary slightly between states.
