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.
The New York WARN Act (the state's Worker Adjustment and Retraining Notification Act) is broader than the federal WARN Act on every dimension. If you have a site in New York, this is the law I would build any restructuring plan around.
The state Act 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. Meeting the federal rules in New York does not make you compliant with state law. Two things make it different, not just stricter.
First, New York has four triggering events where federal law has two. 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. If you are planning a reduction in force in New York, those extra triggers are where the unpleasant surprises live.
The second difference is newer. Since March 2025, the state has asked employers on the WARN filing form whether automation contributed to the job losses, a question no state had asked before.
Does New York Have One?
Yes. The New York State WARN Act sits at Article 25-A of the state Labor Law. Its regulations are in the New York Codes, Rules and Regulations at 12 NYCRR Part 921. As amended effective June 21, 2023, they fold in earlier statutory changes and add 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. Because New York is stricter on the threshold, the notice period, and the triggers alike, a covered New York employer ends up working to the state rules throughout (New York State Department of Labor).
The notice duty itself sits in one sentence of the statute. Section 860-b bars an employer from ordering a mass layoff, relocation, or employment loss until 90 days after written notice has gone out.
That same sentence names who must receive the notice: the affected employees and their representatives, the state Department of Labor, the local workforce investment boards, the chief elected officials of the affected local governments and school districts, and each locality that provides police, fire, or emergency medical services to the site (NY Labor Law 860-b).
Is There a Separate New York City WARN Act?
No. There is no city layoff notice law, so a Manhattan or Brooklyn site is governed by the state Act on the same 50-employee threshold and the same 90-day clock as a site in Buffalo.
What does change inside the city is who the local recipients are. The workforce board that has to be notified is the NYC Workforce Development Board, which asks for completed notices by email. For the school district and emergency services, the recipients are citywide agencies rather than town offices.
Which Employers Are Covered
The Act covers 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 it catches a specific kind of business. A company built on part-time labor may never reach 50 full-time employees while comfortably exceeding 2,000 aggregate weekly hours, the same total that 50 people working 40 hours would produce. Retail, hospitality, home care, and staffing operations should run the aggregate-hours calculation, not just count 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 count is a New York State count, not a national one, so employees in other states do not go toward either test. Nonprofits are not exempt: the regulations define an employer as a business enterprise, for-profit or not-for-profit, and the same two tests apply to both (12 NYCRR 921-1.1).
The Four Triggers
Federal WARN has two triggers, a plant closing and a mass layoff. New York has those two at lower thresholds, plus two more that federal law does not recognize at all.
The last two deserve attention because they break the mental model most employers bring to layoff notice. A relocation is not a reduction: the jobs may all continue, just 50 miles or more down the road, 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.
Both thresholds reward precision. The relocation trigger only bites where the new site is 50 miles or more from the old one and 25 or more full-time employees suffer an employment loss. The hours trigger reads "more than 50 percent," so an exact halving of the schedule does not reach it (12 NYCRR 921-1.1).
Work all four triggers on paper before the decision is announced, because three of them turn on counts and dates that are easy to get wrong in a meeting. The worksheet below records the answer and the numbers it rests on.
The 90-Day Notice
Ninety days of advance written notice is required before the closing, mass layoff, relocation, or covered reduction in hours takes effect. That is thirty days more than federal law, which in practice means the decision has to be settled a full quarter before anything happens.
The familiar exceptions apply: a faltering company (one actively seeking capital or business that would let it avoid or postpone the closing), unforeseeable business circumstances, a natural disaster, and a strike or lockout. New York adds a procedural layer around them (12 NYCRR 921-6.1).
| 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 pieces together its justification later, in response to a claim, argues from a weaker position than one that documented the basis as the decision was made. 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 the governor announced in her January 2025 State of the State, the state Department of Labor added a checkbox to the WARN filing in March 2025.
The checkbox asks 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.
With no statutory text behind it, the checkbox leaves several questions 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.
A bill would move the question from the form into the statute. Senate Bill S8928, the Artificial Intelligence Workforce Impact Transparency Act, would require a WARN notice to state whether the employment losses result from the introduction, expansion, or adoption of AI systems or automation, and would set up a two-year tracking initiative at the Department of Labor.
The bill is not law. It was introduced on January 16, 2026 and referred to the Senate Labor Committee, where it remains (New York State Senate). Until something passes, the checkbox is what exists, and it exists without definitions.
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
The notice goes to five recipients, one of the longest lists in the country, and missing any 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. They include full-time and part-time staff who may reasonably be expected to suffer an employment loss, among them people who will likely lose jobs through bumping rights (a more senior employee taking a junior colleague's job) where they can reasonably be identified.
Managerial and supervisory employees count as affected employees too. Officers, directors, shareholders, and LLC members with a 10 percent or greater ownership interest do not, and neither do certain contractors.
Five recipients, five separate delivery records. Log each one as it goes out rather than reconstructing the picture later, since the failure here is almost always an omission nobody noticed at the time.

Ryan HowardSalesUp to DatePenalties and Enforcement
Back pay and the value of benefits are owed for each day of violation, and the employer can also face a civil penalty of up to $500 for each day of violation. The structure resembles federal WARN. The enforcement does not.
Section 860-g sets the back pay rate at the higher of the average regular rate over the last three years or the final rate. It caps the exposure at the period of the violation, up to 60 days, or at half the number of days the employee worked for the employer, whichever period is smaller (NY Labor Law 860-g).
The civil penalty has an escape hatch worth knowing. Section 860-h sets it at not more than $500 for each day of violation, but it does not apply at all where the employer pays every affected employee the amounts owed under 860-g within three weeks of ordering the mass layoff, relocation, or employment loss (NY Labor Law 860-h).
For an employer, the presence of a regulator cuts both ways. Ambiguities have official answers in New York that do not exist in New Jersey, which helps 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. Wherever the table below shows a difference, plan to the New York rule, because 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, 50 miles or more away, at 25 employment losses |
| Reduction in hours | Only through the employment loss definition | A separate trigger above 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.
Three other states run a 90-day clock. New Jersey 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.
Maine also requires 90 days, but only before closing an establishment of 100 or more people or moving it 100 or more miles (Maine Legislature). Nebraska joined the group on July 18, 2026, requiring 90 days before a closing or mass layoff that costs 100 or more employees their jobs at one site, part-time staff excluded (Nebraska Legislature, LB 921).
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 below both tests, the obligations that remain are the ordinary ones, and they arrive faster than WARN would. The New York final pay deadline comes first, on its own clock and regardless of how the separation was decided.
The rest of the sequence is paperwork and access. A written termination letter goes out, a documented offboarding run happens alongside it, systems access comes off the same day, and the record of how people were selected gets retained.
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. New York has its own version of the law in Article 25-A of the state Labor Law. The Department of Labor rules that implement it are codified at 12 NYCRR Part 921, and their current version took effect on June 21, 2023, absorbing earlier statutory changes. The state law goes further than federal WARN on every axis that matters. Coverage starts at 50 full-time employees rather than 100, notice runs 90 days rather than 60, and the mass layoff trigger is 25 employees rather than 50. New York also requires notice for two events that federal law does not treat as triggers: relocating operations and cutting work hours for a sustained period. Because the state rules are stricter on both the notice period and the thresholds, an employer in New York that satisfies federal WARN has not yet satisfied state law.
How many employees does the New York WARN Act cover?
Fifty. An employer is covered once it has 50 or more full-time employees in New York, and it is also covered when its New York staff, part-time workers included, number 50 or more and together put in at least 2,000 hours per week. The second route is the one that businesses leaning on part-time staff tend to miss, because a team that never has 50 full-time people can still clear the aggregate-hours bar. Federal WARN starts at 100 employees, which leaves a broad band of mid-size employers covered in New York but outside the federal law entirely. Before deciding the Act does not apply, test both routes, and use your headcount in New York rather than your national total.
How much notice does the New York WARN Act require?
Ninety days of advance written notice, which is thirty days longer than federal WARN requires. Work backward from the date the plant closing, mass layoff, relocation, or covered reduction in work hours takes effect, and make sure the notice goes out at least 90 days before it. When an exception allows a shorter period, the employer still owes as much notice as is practicable, and the notice itself has to explain why the period was shortened, set out the facts behind the exception claim, and come with any other documents the commissioner requires. The burden of proving the exception sits with the employer, so the justification should be written down before the shortened notice is sent, not reconstructed after a claim arrives.
Does New York require employers to disclose AI-related layoffs?
The filing form asks, even though the statute does not. In March 2025 the New York State Department of Labor, acting on a directive the governor announced in her January 2025 State of the State, put a new checkbox on its WARN submission about whether technological innovation or automation helped cause the layoffs being reported, with a follow-up asking the employer to name the technology. No state had collected this information before. Because the legislature did not amend the Act to add it, the disclosure is a change to the form rather than a statutory duty, and employers have questioned whether answering is mandatory, how the key terms are defined, and whether the question means a contributing factor or the sole cause. Senate Bill S8928, introduced in January 2026 and still in the Senate Labor Committee, would write the requirement into the statute, but until it passes the law is unchanged. Whatever you answer should match what your own records say about the reasons for the cuts.
Who enforces the New York WARN Act?
The New York State Department of Labor, and that sets the state apart from both federal WARN and New Jersey. At the federal level, the U.S. Department of Labor has no enforcement power under WARN, and claims can only be brought in federal district court. New Jersey’s labor department says it has no enforcement or rulemaking authority under its own statute. New York’s department, by contrast, runs the Act, has written detailed regulations for it, and can impose civil penalties. That shapes how a problem plays out for a New York employer. There is a state agency to deal with, a published set of rules to work from, and an administrative track to any dispute, alongside whatever claim an affected employee brings directly.
Does the New York WARN Act cover a reduction in hours?
Yes. A covered reduction in work hours is one of the two triggers New York adds to federal law’s plant closing and mass layoff. It is met when hours drop by more than 50 percent in every month for six months in a row, and the cut reaches either 25 or more full-time staff making up 33 percent of the full-time workforce at the site, or 250 or more full-time staff. The bar is strictly above half, so a cut of exactly 50 percent falls short, and the percentages need to be worked out rather than estimated. What sets this trigger apart is that notice can be owed even though nobody loses a job. An employer that moves a large group from 40 hours to 15 to avoid layoffs, and keeps them there for six months, may owe 90 days of notice for a decision taken to protect jobs.
