WARN Act and Mergers — Who Owes the 60-Day Notice When a Business Is Sold?

When a company is sold, layoffs often follow — and workers are left asking a practical question: who was supposed to give the 60-day notice, the seller or the buyer? The WARN Act has a specific rule for this, and it turns on two things: the effective date of the sale, and whether the buyer keeps the workers on.

The basic rule, briefly

The federal WARN Act requires employers with 100 or more full-time employees to give 60 days' written notice before a plant closing or a mass layoff. A covered "employment loss" means a termination, a layoff lasting more than six months, or a cut in hours of more than 50 percent lasting more than six months. The law is a notice law, not a payment law: it does not require severance, and it does not forbid layoffs. It requires warning. A sale splits that timeline in two, which is where the confusion starts.

The sale-of-business rule

Federal regulations at 20 CFR 639.4 set out who is responsible when a business changes hands. The seller is responsible for giving notice for any covered layoffs that take effect up to and including the effective date of the sale. The buyer becomes responsible for notices for layoffs that take effect after that date. The notice clock is tied to the sale date, not to when the deal was announced or when workers first heard rumours.

There is an important exception: if the buyer hires the seller's employees, those workers have not suffered an employment loss for WARN purposes. A worker who moves from the seller's payroll to the buyer's payroll in the same job has not been laid off. Problems arise when the buyer hires only some of the workforce, or hires workers on different terms, or plans cuts shortly after closing.

Stock sales versus asset sales

The form of the deal matters too. In a stock sale, the company itself continues to exist — only its owners change — so the notice obligation stays with the company throughout, even though workers see new owners and management.

In an asset sale, the buyer purchases the business's assets and typically becomes a new employer. That is where the seller/buyer split does its real work: the seller covers the period up to closing, the buyer covers what comes after, and who hired whom determines whether a WARN notice was owed at all. Workers rarely know which structure a deal used; one clue is the notice itself, which names the employer, the site, and the number of affected workers. A filing under the seller's name for a date after closing, or under the buyer's name for a date before it, is worth raising with the state rapid response team or an employment lawyer.

A real example: Pep Boys after the Mavis acquisition

The pattern shows up in the current WARN data. Mavis Tire's acquisition of Pep Boys closed in August 2026. Weeks later, Pep Boys Manny Moe & Jack, LLC filed a WARN notice for 169 corporate workers at its Bala Cynwyd, Pennsylvania headquarters, with a notice dated September 23, 2026 and layoffs effective December 31, 2026. The filing described a reorganisation of corporate support services after the acquisition.

The example shows the timeline workers face in these deals: a sale closes, integration plans take shape, and a notice follows — sometimes months later. The notice period here ran from late September to the end of December. Not every deal follows that pattern; some notices arrive with far less lead time, and some post-sale cuts fall below WARN thresholds entirely.

What to check if your employer is sold

First, find out who your employer is after the sale — the name on your pay stub and your offer letter, if the buyer reissued one. Second, watch for a WARN filing under either company's name; the registry records the filing employer, and a filing under the buyer's name for a post-closing layoff is the normal pattern. Third, keep any written offer from the buyer, including changes to pay, hours, or location: a substantially different job can matter if you are deciding whether you were truly retained. Fourth, remember state mini-WARN laws can be stricter — some cover smaller employers, require longer notice, or mandate severance. The federal rule is a floor, not the whole picture.

If no notice was given

When a covered employer fails to give the required 60 days' notice, affected workers may be owed back pay and benefits for each day of the violation, up to 60 days, and the employer can face a civil penalty of up to $500 per day payable to the local government. These claims have deadlines and depend on the facts of the sale, so workers who suspect a missed notice should get advice promptly.

The current registry picture, as of November 2, 2026: 686 notices covering 66,703 reported workers in the 90-day window, with 29 counts unavailable. California (17,715) and Washington (17,361) lead, followed by Illinois (4,385), Texas (3,280), and Georgia (2,492). By effective week: November 1, 4,017; November 8, 5,311; November 15, 7,830; November 22, 6,614; November 29, 5,922; December 6, 721.

These figures are reported plans, not confirmed job losses. WARN filings describe what employers say they intend to do; some layoffs are postponed, reduced, or cancelled, and coverage varies by state.
