NY WARN Notice: Requirements, Triggers, and Penalties

Under the New York WARN Act, notice requirements oblige private employers with 50 or more full-time workers to give 90 days’ written notice before a mass layoff, plant closing, relocation, or major reduction in hours. The notice has to reach affected employees, their unions, the State Department of Labor, the local Workforce Development Board, chief elected local officials, and local emergency service providers. Skip it or shorten it without a valid exception, and the employer owes each affected worker up to 60 days of back pay plus benefits, on top of a civil penalty of up to $500 for every day of violation.¹

Which Employers Have to Give Notice

The law reaches any private business, for-profit or not-for-profit, that has at least 50 full-time employees in New York State, or at least 50 total employees (including part-timers) working a combined 2,000 or more hours per week. Federal, state, and local government agencies, including school districts, are not covered.²

“Part-time employee” is a term of art. It means a worker who averages fewer than 20 hours a week, or who has been on the payroll for fewer than six of the previous 12 months. Part-timers don’t count toward the 50-employee threshold, and they don’t count when measuring whether a layoff hits the numeric triggers below.²

What Triggers the 90-Day Notice

Four kinds of workforce actions start the clock. The numbers are lower than most employers assume, and small cuts spread out over time can add up to a triggering event.

Mass Layoff

A mass layoff occurs when, in any 30-day period at a single site, an employer lays off at least 25 full-time employees who also make up at least 33 percent of that site’s full-time workforce. If the layoff reaches 250 or more full-time employees at one site, the percentage test drops out and notice is required no matter the workforce size.²

Plant Closing

A plant closing is the permanent or temporary shutdown of a single site, or of one or more facilities or operating units within a site, that causes an employment loss for 25 or more full-time employees during any 30-day period. Partial closures, such as shutting a specific division or production line, count.²

Relocation

Moving all or substantially all operations to a site 50 or more miles away counts as a covered relocation when 25 or more full-time employees lose their jobs as a result. “Substantially all” includes moving an entire unit, product line, or division.²

Reduction in Hours

Notice is required when at least 25 employees, making up at least 33 percent of a site’s workforce, have their hours cut by more than 50 percent in each month of any six consecutive months.³

The Aggregation Trap

“Employment loss” means an involuntary termination (other than for cause, voluntary departure, or retirement), a layoff of more than six months, or the hour reduction described above. If an employer offers to transfer a worker to a site within a reasonable commuting distance with no more than a six-month gap, that transfer isn’t an employment loss.²

Employers have to look 30 days forward and 30 days back from each employment action, and a separate 90-day aggregation window also applies. Staggering cuts to stay just under the thresholds doesn’t work: if the combined actions within either window reach the minimums, the full notice obligation kicks in.³

What Has to Be in the Notice

New York adopts every element the federal WARN Act requires and adds more on top. The Department of Labor publishes templates and requires filings through its WARN Portal, but making sure each required item is present is the employer’s job.⁴

The notice to the Commissioner of Labor has to cover:

The employer’s full legal name, any trade names, and the address of each affected site.
Contact details for both the company representative filing the notice and the liaison for rapid-response services.
A list of every affected worker with name, home address, phone, email (if known), job title, work location, pay type (hourly, salaried, commission), full- or part-time status, and any union affiliation. The Department requires this list on its specific spreadsheet template.
The expected first separation date and a schedule of any additional layoffs. A 14-day window can be substituted for a specific date, but the 90-day period then runs from the first day of that window.
Whether the closing or layoff is temporary or permanent, whether the whole site is closing, and how different units will be affected.
A statement about whether senior employees have bumping rights over more junior workers.
For unionized workforces, each union’s name, the chief elected officer’s contact information, and any bumping-rights provisions.

All of this is submitted through the NY DOL WARN Portal using a NY.gov account. Employers also upload signed copies of the notices sent to local officials, and, if the filing is going in with fewer than 90 days’ lead time, a detailed written explanation of the exception being claimed.⁴

Who Must Receive the Notice

The statute names six categories of recipients, and missing any one of them is itself a compliance failure. Written notice has to go to:⁵

Every worker who may reasonably be expected to lose their job.
The union representing any affected employees. Federal WARN lets the union stand in for its members; New York requires notice to both.
The New York State Department of Labor.
The local Workforce Development Board for the area where the site sits.
The chief elected official of each local government and school district covering the site.
Local providers of police, fire, EMS, or ambulance services to the site.

Notice to employees has to be in a language they can understand. Acceptable methods include first-class mail, certified mail, or inclusion in a paycheck. Email is permitted only when every affected employee has regular access to a personal work computer during business hours. If an email bounces, the employer has to re-deliver by a faster method and extend the notice period by the number of days the re-delivery took.⁴

When Shorter Notice Is Allowed

Several situations reduce or eliminate the 90-day requirement, but even with a valid exception the employer still has to give as much notice as is practicable and submit a written explanation for the shortfall.⁶

Faltering company. The employer was actively seeking capital or new business, the financing would have been enough to avoid or postpone the shutdown, and the employer reasonably believed in good faith that public notice would have driven the capital source away. This one applies only to plant closings, not to mass layoffs.
Unforeseeable business circumstances. The need for the action was not reasonably foreseeable when the 90-day clock would have started. A major client abruptly canceling a contract is the classic example.
Natural disaster. A flood, earthquake, storm, drought, or similar event caused the closing or layoff.
Physical calamity, terrorism, or war. No notice at all is required when the layoff results directly from a physical calamity or an act of terrorism or war.
Temporary project. Workers were hired understanding their jobs would last only as long as a specific project or temporary facility.
Strikes and lockouts. A closing or layoff that is itself a strike or a lockout doesn’t trigger the notice requirement, provided the lockout isn’t a device to evade WARN.

The burden of proving an exception falls on the employer, and the WARN Portal requires a detailed written statement on company letterhead plus supporting documentation whenever a filing goes in short.⁴

Penalties for Skipping or Shortening Notice

Violations produce two separate liabilities: money owed to each affected employee and a civil penalty paid to the state.

An employer that orders a mass layoff or plant closing without proper notice owes each affected worker back pay for every day of the violation, plus the cost of any medical expenses the employee incurred that would have been covered by their employer health plan. This liability is capped at 60 days, or half the total number of days the employee worked for the company, whichever is shorter. The employer can offset that amount by subtracting wages paid during the violation period, voluntary unconditional payments to the employee, payments to third parties on the employee’s behalf (health premiums, pension contributions), and any amounts already paid under the federal WARN Act for the same incident. Employees can sue directly, or the Commissioner of Labor can sue on their behalf, and courts have discretion to award reasonable attorney’s fees to a prevailing employee.¹

On top of that, the employer faces a civil penalty of up to $500 for each day of violation, recovered by the Commissioner in a separate action. The employer can avoid this civil penalty by paying all affected employees the back pay and medical expenses they are owed.⁷

The exposure adds up quickly. A mid-size employer laying off 50 workers without proper notice can face 60 days of back pay per worker, uncovered medical costs, and a $500-per-day state penalty, easily reaching hundreds of thousands of dollars.

When a Business Is Sold

A sale doesn’t erase the notice obligation, it just shifts who carries it. The seller is responsible for any plant closing or mass layoff that happens up to and including the effective date of the sale. After closing, the buyer takes over for any subsequent layoffs. Any employee of the seller on the sale date is treated as an employee of the buyer immediately afterward, so a change of ownership by itself is not an employment loss. A promise of continued employment from the buyer does not let the seller off the hook; if the seller knows layoffs are likely to accompany the sale, the seller has to file.⁵

If You Are an Affected Employee

Receiving a WARN notice means your employer is legally required to give you at least 90 days before your last day. During that period you remain employed, at your regular pay and benefits, and the notice itself tells you the expected separation date and whether the layoff is temporary or permanent.

If your employer failed to give the full 90 days and no exception applies, you have a claim for back pay and medical expenses for each day of the shortfall. You can pursue that claim yourself or wait for the Commissioner of Labor to act on your behalf. The Department of Labor publishes all active and recent WARN filings on its website, so you can check whether your employer actually filed one.
