A WARN notice tells you a layoff is coming, not why you were chosen. That gap matters: the WARN Act and the laws against age discrimination do different jobs, and a layoff can satisfy one while violating the other.
The WARN Act is a notice law: 60 days' warning before a plant closing or mass layoff. It never asks whether the selection was fair. The Age Discrimination in Employment Act (ADEA) is the law that asks that question. If you are 40 or older, knowing how the two laws work together can mean the difference between accepting a layoff and spotting an unlawful one.
The WARN Act doesn't ask why you were picked
Federal WARN covers employers with 100+ full-time employees, triggered by a plant closing of 50+ employees or a mass layoff of 50+ (at least one-third of a site's workforce) or 500+.
The notice must say which site is affected, whether the layoff is permanent or temporary, when it takes effect, and which jobs are affected. What it never has to explain is the selection method. An employer can comply with WARN perfectly — full 60 days, every required fact — while choosing the layoff list in a way that discriminates by age. WARN compliance is no defence to an age claim, and an age claim excuses no missing WARN notice — a worker can have a claim under either or both.
The ADEA: 40 and older is a protected class
The ADEA bars employers with 20+ employees from discriminating against workers 40 or older in any term of employment, including layoff selection. Two kinds of claims matter.
The first is disparate treatment: age was a factor in the decision. Direct evidence is rare; patterns count. If the layoff list is heavy with workers in their fifties and sixties while younger workers in the same roles stay, that pattern is evidence worth documenting.
The second is disparate impact: a rule that looks neutral but hits older workers hardest. Salary-based cuts are the classic example — the highest-paid employees are often the longest-tenured, and the longest-tenured are often the oldest. A "cut the top 10 percent of earners" rule can be challenged if it falls disproportionately on workers over 40, unless the employer can show a reasonable factor other than age. The Supreme Court recognised such claims in Smith v. City of Jackson (2005).
Neutral-sounding criteria can hide the same problem: performance scores depend on who rated whom, and skills-based selection depends on which skills were counted. Compare the ages of those leaving with the ages of those staying in the same roles, and note anything managers said about age, retirement, or "fresh energy" — such comments are the evidence discrimination cases are built on.
The OWBPA disclosure: the list your employer must hand you
This is where the two laws overlap. The Older Workers Benefit Protection Act (OWBPA), a 1990 ADEA amendment, sets strict conditions for waiving age discrimination claims — the release most employers ask you to sign for severance. In a group layoff, the waiver is only valid if the employer gives you, in writing, the decisional unit, the eligibility factors used, and the job titles and ages of everyone selected — and of everyone in the same unit who was not selected.
You also get 45 days to consider the agreement in a group termination (21 days for an individual one), and 7 days to revoke after signing. That 45-day clock runs alongside the 60-day WARN period.
Read the disclosure list carefully: it is the one document that shows, in black and white, whether the layoff fell mainly on older workers. If most of the people kept are younger and in the same jobs, talk to an employment lawyer before you sign anything.
What to do in the 60-day window
First, do not sign a severance waiver on the spot. You have at least 45 days in a group layoff, and signing early gives up your ADEA claim for nothing — the severance is the same either way. Second, ask for the OWBPA disclosure if it was not provided; in a group termination it is a legal requirement, not a courtesy. Third, file promptly if you believe age played a role: an EEOC charge must generally be filed within 180 days of the discriminatory act, or 300 days in states with their own fair-employment agency. Waiting past the deadline ends the claim, even if the facts are strong.
A WARN notice is not the end of your rights — it is the start of a 60-day period in which you can check whether the selection was lawful and get advice before signing anything away.
The numbers right now
Layoff Atlas is tracking 705 WARN notices covering 65,089 reported workers in a 90-day window, with 31 notices where the worker count was not available. California leads with 21,514 reported workers, followed by Washington at 17,411, Illinois at 3,548, Texas at 2,750, and Virginia at 2,546. The heaviest upcoming week is November 15, with 7,887 workers scheduled, followed by November 22 (6,614), November 29 (6,156), and December 13 (5,307). The week of November 8 has 4,267 scheduled; December 6 is the lightest at 857.
These are reported plans, not confirmed job losses — coverage and reporting rules vary by state.

The key point: WARN compliance and ADEA compliance are completely independent. An employer can give perfect 60-day notice and still select the layoff list by age. The OWBPA disclosure is the document that actually shows the pattern — and it's a legal requirement, not a favour.
