New York WARN Act Requirements for Employers
New York WARN Act rules: the 50-employee threshold, 90-day notice, four triggers including relocation and reduced hours, the AI disclosure, and penalties.
New York WARN Act Requirements for Employers
New York covers employers at 50 employees, requires 90 days of notice, and adds two triggers federal law does not have: relocation and a sustained reduction in hours. It is also the first state to ask employers whether automation caused the layoff.
The New York WARN Act is broader than the federal WARN Act on every dimension. It covers employers at 50 employees instead of 100, requires 90 days of notice instead of 60, and sets the mass layoff trigger at 25 people instead of 50. Complying with federal law in New York does not get you to compliance with state law.
Two things make it genuinely different rather than just stricter. New York has four triggering events where federal law has two, and the extra pair, a relocation of operations and a sustained reduction in work hours, can be set off by decisions that are not layoffs at all. And since March 2025, the state asks employers on the filing form whether automation contributed to the job losses, which no other state does. If you are planning a reduction in force in New York, the extra triggers are where the unpleasant surprises live.
Does New York Have One?
Yes. The New York State WARN Act sits at Article 25-A of the state Labor Law, and the implementing regulations at 12 NYCRR Part 921 took effect on June 21, 2023, folding in earlier amendments and adding clarifications on remote work and on the documentation required to claim an exception.
Both laws can apply at once, and where they differ the stricter requirement governs in practice. Since New York is stricter on the threshold, the notice period, and the triggers simultaneously, a covered New York employer is effectively working to the state rules throughout (New York State Department of Labor).
Which Employers Are Covered
A business enterprise with 50 or more full-time employees in New York, or alternatively 50 or more employees including part-time staff who work at least 2,000 hours a week in the aggregate.
That second test is easy to miss and catches a specific kind of business. A company built on part-time labour may never reach 50 full-time employees while comfortably exceeding 2,000 aggregate weekly hours, which is roughly what 50 people working 40 hours would produce. Retail, hospitality, home care, and staffing operations should run the aggregate calculation rather than counting heads on the full-time roster.
The regulations also address remote employees, who are generally attributed to the site to which they report rather than to where they physically sit. For a New York office serving as the reporting home for a distributed team, the site headcount can be substantially larger than the number of people who come in.
The Four Triggers
Federal WARN has a plant closing and a mass layoff. New York has those two at lower thresholds, plus two more that federal law does not recognise at all.
The last two deserve attention because they break the mental model most employers bring to this. A relocation is not a reduction: the jobs may all continue, just somewhere else, and the obligation still arises. A covered reduction in hours is not a termination either, and it can be triggered by a decision made specifically to avoid terminations.
The 90-Day Notice
Ninety days of advance written notice before the closing, mass layoff, relocation, or covered reduction in hours takes effect. Thirty days more than federal law, and the practical consequence is that the decision has to be settled a full quarter before anything happens.
The familiar three exceptions apply, but New York adds a procedural layer around them.
| Requirement when claiming an exception | Detail |
|---|---|
| Give as much notice as is practicable | The exception shortens the period; it never removes the obligation to notify |
| State the reason | The notice must include a statement of the reason for reducing the notice period |
| Give a factual basis | A factual explanation of the basis for claiming entitlement to the reduced period |
| Supply documents | Any other documents the commissioner requires to establish eligibility for the exception |
| Burden of proof | The employer bears it, so the record has to exist when the shortened notice goes out |
That last row is the operative one. An employer that shortens notice and assembles its justification later, in response to a claim, is arguing from a weaker position than one that documented the basis contemporaneously. Build the file at the time.
The AI Disclosure
New York was the first state to ask employers whether technology caused the job losses. Following a directive from the governor in January 2025, the state Department of Labor added a checkbox to the WARN filing in March 2025 asking whether technological innovation or automation contributed to the reported layoffs. Check it, and a follow-up prompt asks which technology was involved.
Here is the part that matters for compliance and that most coverage skips: the statutory language of the Act was not amended. The disclosure exists as a change to the filing system rather than as a legislative requirement, which leaves several questions genuinely open. Whether completing it is mandatory or optional. How technological innovation and automation are defined. And whether the question asks about a contributing factor or about the sole cause of the reduction.
The practical advice is unglamorous. Answer the question accurately and in a way that matches your internal record of why the decision was made. A filing that says nothing about automation while the board minutes say otherwise is the kind of inconsistency that surfaces later, and the filed notices sit in a public archive.
Who Receives the Notice
New York has one of the longest recipient lists in the country, and missing one of them is a compliance failure even where the employees were notified properly.
| Recipient | Note |
|---|---|
| Affected employees | Individual written notice to each employee expected to suffer an employment loss |
| Employee representatives | Any union or other representative of the affected employees |
| New York State Department of Labor | Filed through the state WARN system, which includes the automation question |
| Local workforce investment board | The board serving the area where the site is located |
| Chief elected officials of local government | Including the school district and, where applicable, the locality providing emergency services to the site |
The regulations define affected employees broadly, covering full-time and part-time staff who may reasonably be expected to suffer an employment loss, including people who will likely lose jobs through bumping rights where they can reasonably be identified. Managerial and supervisory employees are included; officers, directors, shareholders, and LLC members are not.
Penalties and Enforcement
Back pay and the value of benefits for each day of violation, up to 60 days, for each affected employee, plus a civil penalty of up to $500 for each day of violation. The structure resembles federal WARN. The enforcement does not.
For an employer, the presence of a regulator cuts both ways. Ambiguities have official answers in New York that simply do not exist in New Jersey, which is genuinely useful when planning. But the state also reviews what is filed, and the notices are public, so a submission that does not match the event that follows is visible.
New York vs Federal WARN
Both laws can apply to the same reduction. On every row below, satisfying the federal requirement leaves the state obligation outstanding.
| Requirement | Federal WARN | New York |
|---|---|---|
| Employer threshold | 100 or more employees | 50 or more full-time, or 50 including part-time at 2,000+ aggregate weekly hours |
| Notice period | 60 days | 90 days |
| Plant closing trigger | 50 or more employment losses | 25 or more full-time employment losses |
| Mass layoff trigger | 500 or more, or 50 to 499 at 33 percent of the site | 250 or more, or 25 or more at 33 percent of the site |
| Relocation | Not a separate trigger | A separate triggering event |
| Reduction in hours | Only through the employment loss definition | A separate trigger at 50 percent over six consecutive months |
| Automation disclosure | None | Checkbox on the state filing form since March 2025 |
| Enforcement | Federal district court; DOL does not enforce | State Department of Labor administers and can assess penalties |
The two rows that most often catch employers are the mass layoff trigger and the reduction in hours. Twenty-five people at a third of a site is a much lower bar than fifty at a third, and a site of 75 full-time employees reaches it with 25 separations. Compare with California, which takes a different route through a 75-employee threshold, in our California WARN Act guide.
The other 90-day state is New Jersey, which reaches breadth differently: it keeps the 100-employee threshold but counts part-time staff toward it, counts the layoff trigger statewide, and adds mandatory severance. New York is broader in what sets the obligation off; New Jersey is more expensive once it does.
Under the Threshold
Below 50 full-time employees, and below the 2,000 aggregate weekly hours alternative, New York WARN does not apply and no advance notice is required. That covers most small businesses in the state.
Check the aggregate-hours test before concluding you are clear, though. A restaurant group or home care agency with 30 full-time and 45 part-time staff may cross 2,000 weekly hours without ever having 50 people on the full-time roster, and the alternative test exists precisely to capture that shape of workforce.
If you are genuinely below, the obligations that remain are the ordinary ones and they arrive faster than WARN would. The New York final pay deadline comes first, covered in our guide to the final paycheck for a terminated employee. Then a written termination letter, a documented offboarding sequence, same-day access removal, and a retained record of how people were selected.
Running that as an assigned workflow rather than an email thread is what FirstHR handles: separation documents go out for e-signature with a dated record, offboarding tasks are assigned and tracked to completion, and everything files against the employee profile. FirstHR is an onboarding and HR platform, not a law firm and not a payroll provider, so it does not determine WARN coverage, prepare state filings, or issue final wages. Applicant tracking is coming soon to FirstHR.
Frequently Asked Questions
Does New York have its own WARN Act?
Yes. The New York State WARN Act sits at Article 25-A of the state Labor Law, with implementing regulations at 12 NYCRR Part 921 that took effect on June 21, 2023 and incorporated earlier amendments. It is materially broader than the federal WARN Act on every axis that matters. It covers business enterprises with 50 or more full-time employees rather than 100, requires 90 days of advance notice rather than 60, sets the mass layoff trigger at 25 employees rather than 50, and adds two triggering events federal law does not have at all: a relocation of operations and a sustained reduction in work hours. An employer complying with federal WARN in New York has not thereby complied with state law, because the state requirements are stricter on the notice period and the thresholds alike.
How many employees does the New York WARN Act cover?
Fifty. The Act applies to a business enterprise with 50 or more full-time employees in New York, or alternatively 50 or more employees including part-time staff who work at least 2,000 hours per week in the aggregate. That alternative test matters for businesses built on part-time labour, because a workforce that never reaches 50 full-time employees can still cross the aggregate-hours line. The federal threshold is 100 employees, so New York brings in a large band of mid-sized employers who are outside federal WARN entirely. Run the count both ways before concluding you are not covered, and remember that the count is measured against the New York workforce rather than nationally.
How much notice does the New York WARN Act require?
Ninety days of advance written notice, thirty days more than federal WARN. The notice must go out at least 90 days before the plant closing, mass layoff, relocation, or covered reduction in work hours takes effect. Where an exception permits a shortened period, the employer must still give as much notice as is practicable and must include a statement of the reason for reducing the period along with a factual explanation of the basis for the claim, plus any other documents the commissioner requires. The employer bears the burden of proving that an exception applies, so the documentation needs to exist at the time the shortened notice goes out rather than being assembled later in response to a claim.
Does New York require employers to disclose AI-related layoffs?
The state WARN filing form asks the question. Following a directive from the governor in January 2025, the New York State Department of Labor added a checkbox to the WARN submission in March 2025 asking whether technological innovation or automation contributed to the reported layoffs, and if the box is checked, the employer is prompted to name the technology involved. New York was the first state to collect this data. Importantly, the statutory language of the Act was not amended to add the disclosure, so it exists as a form change rather than a legislative requirement, and employers have questioned whether it is mandatory, how the terms are defined, and whether it asks about a contributing factor or the sole cause. Complete it accurately and consistently with your internal record of the decision.
Who enforces the New York WARN Act?
The New York State Department of Labor, which is a meaningful difference from both federal WARN and the New Jersey statute. Under federal WARN the Department of Labor has no enforcement authority and claims proceed only in federal district court, and the New Jersey labor department states that it has neither enforcement nor rulemaking authority under its own act. New York is not in that position: the state department administers the Act, has issued detailed regulations under it, and can assess civil penalties. For an employer, that changes the practical shape of a problem. There is an agency to engage with, published regulations to work from, and an administrative dimension to any dispute in addition to whatever an affected employee may pursue directly.
Does the New York WARN Act cover a reduction in hours?
Yes, and this is one of the two triggers with no federal counterpart. A covered reduction in work hours occurs where there is a reduction of 50 percent or more in hours during each month of any consecutive six-month period, affecting either 25 or more full-time employees who represent 33 percent of the full-time workforce at the site, or 250 or more full-time employees. The practical significance is that an employer can trigger the notice obligation without terminating anyone. A business that cuts a large group to half time to avoid layoffs, and keeps them there for six months, may owe 90 days of notice for a decision it made specifically to preserve jobs. Model the six-month picture before committing to a sustained hours reduction.
