State WARN Acts: A Guide for HR Leaders
In addition to the federal Worker Adjustment and Retraining Notification (WARN) Act, which was enacted in 1988, several U.S. states and jurisdictions have adopted their own WARN laws to address workforce reductions within their jurisdictions. Today, 18 jurisdictions have enacted local WARN laws—commonly referred to as "mini-WARN" acts—which often establish different employee thresholds, notice periods, triggering events, or employer obligations than the federal WARN Act. Use the interactive map below to explore state WARN Act requirements and compare notice obligations across the United States.

How State WARN Laws Differ from the Federal WARN Act
While the federal WARN Act establishes baseline notice requirements for certain mass layoffs and plant closings, state WARN laws often expand on those requirements to provide greater protections for employees. Depending on the jurisdiction, employers may be subject to lower employee thresholds, longer notice periods, broader definitions of covered employment actions, additional notice recipients, or mandatory severance obligations.
For example, Iowa's WARN law requires notice for layoffs affecting as few as 25 employees, while New Jersey's WARN Act requires employers to provide mandatory severance to affected employees when the law is triggered—a requirement that does not exist under the federal WARN Act. In New York, employers must disclose whether artificial intelligence (AI) played a role in employment decisions leading to layoffs. Other states have adopted their own thresholds, notice periods, and compliance requirements that differ from federal law.
Because these requirements vary by jurisdiction—and continue to evolve—employers planning a workforce reduction should evaluate for federal WARN obligations and any applicable state or local WARN laws before implementing a reduction in force (RIF).
The Growing Complexity of State WARN Act Compliance
Understanding the law is only part of the challenge. Employers must keep pace with the rapidly evolving regulatory landscape while coordinating workforce reductions across teams, including HR, Legal, Finance, and business leaders. Many organizations still rely on spreadsheets, email, and other manual processes to track WARN Act requirements. As state WARN laws continue to evolve, keeping those processes current becomes increasingly difficult. Organizations conducting workforce reductions across multiple jurisdictions must monitor changing legal requirements, determine which laws apply, coordinate notice obligations, and maintain accurate documentation—all while working within tight timelines.
Can Technology Help Manage Multi-State WARN Compliance?
Yes. As state WARN laws become more complex, many organizations are moving beyond spreadsheets and manual checklists to technology that helps manage compliance throughout the workforce reduction process.
In addition to WARN Act compliance, employers must also coordinate employee selection, severance policies, separation agreements, OWBPA disclosures for employees age 40 and older, required notices, approvals, documentation, and employee communications. Managing these activities using disconnected systems can increase administrative effort, make cross-functional coordination more difficult, and create unnecessary compliance risk during an already challenging time for both employers and employees.
Onwards HR helps organizations manage the entire workforce reduction process in one centralized platform. Onwards HR brings together WARN Act compliance, severance, documentation, and employee communications to help HR, Legal, and Finance execute workforce reductions with consistency, compliance, and compassion.
With Onwards HR, organizations can:
Plan and manage reductions in force using real-time workforce data
Manage federal and state WARN Act compliance as part of a centralized workforce reduction process
Generate required documentation, including OWBPA disclosures for employees age 40 and older, separation agreements, and WARN notices
Configure and manage severance policies by entity, country, union, and other organizational rules
Keep HR, Legal, and Finance aligned through one centralized workflow while maintaining a complete audit trail
As workforce reductions become more complex and state employment laws continue to shift, a centralized approach to offboarding helps organizations reduce manual coordination, improve consistency, and better manage compliance throughout the employee separation process.
Frequently Asked Questions
What is a state WARN Act?
A state WARN Act, often called a mini-WARN law, is a local law that requires certain employers to provide advance notice before qualifying mass layoffs, plant closings, or relocations. While these laws are modeled after the federal Worker Adjustment and Retraining Notification (WARN) Act, many states have expanded the requirements by establishing different employee thresholds, notice periods, triggering events, or additional employer obligations. Employers should evaluate both federal and applicable state WARN laws when planning a workforce reduction.
Which states have their own WARN laws?
As of July 2026, 18 jurisdictions have enacted their own WARN laws, often referred to as mini-WARN laws, including California, Delaware, Hawaii, Illinois, Iowa, Maine, Maryland, Minnesota, Nebraska, New Hampshire, New Jersey, New York, Ohio, Tennessee, Vermont, Washington, and Wisconsin.
In addition, Philadelphia, Pennsylvania has a local workforce reduction ordinance. While Pennsylvania does not have a statewide mini-WARN law, employers conducting qualifying layoffs within the City of Philadelphia may be subject to local notice requirements that differ from the federal WARN Act.
Not every state with workforce notification statutes has a mandatory mini-WARN law. For example, Minnesota encourages employers to provide advance notice of layoffs under Minn. Stat. § 116L.976, but it does not establish an independent notice requirement beyond the federal WARN Act.

How do state WARN laws differ from the federal WARN Act?
State WARN laws often expand upon the federal WARN Act by establishing different employee thresholds, notice periods, triggering events, notice recipients, or employer obligations. For example, some states require notice for layoffs affecting fewer employees than the federal law, while New Jersey requires mandatory severance when its WARN law is triggered. Other states have adopted unique requirements related to layoffs, relocations, or employee notifications. Employers should evaluate both federal and state requirements to determine which obligations apply.
Does federal WARN Act override state WARN laws?
No. The federal WARN Act generally does not override state WARN laws. When a state has enacted its own WARN law, employers may need to comply with both the federal law and the applicable state law. If the state law provides greater employee protections or imposes additional employer obligations, those requirements supersede. Because the interaction between federal and state laws can be complex, employers should review the specific requirements of each jurisdiction before proceeding with a workforce reduction.
Which WARN law applies if both federal and state laws are triggered?
If both the federal WARN Act and a state WARN law apply to the same workforce reduction, employers are generally expected to comply with both sets of requirements. Because state WARN laws often establish different thresholds, notice periods, or employer obligations, compliance with the federal WARN Act alone may not satisfy state law. Employers should identify all applicable federal and state requirements before issuing notices or implementing a reduction in force.
How do remote employees affect WARN Act compliance?
Remote and hybrid work arrangements can make WARN Act compliance more complex. Determining an employee's employment site under the federal WARN Act may differ from where the employee lives or works remotely, and some state WARN laws may have their own requirements or interpretations. For organizations with employees working in multiple states, evaluating which WARN laws apply—and where notice obligations are triggered—often requires careful review of both federal guidance and applicable state law.
Does the WARN Act require severance pay?
The federal WARN Act does not require employers to provide severance pay. However, some state WARN laws impose additional obligations. For example, New Jersey's WARN Act generally requires mandatory severance when the law is triggered. Employers should review applicable state laws, employment agreements, collective bargaining agreements, and company severance policies when planning a workforce reduction.
What happens if an employer fails to comply with the WARN Act?
Employers that fail to comply with the federal WARN Act or an applicable state WARN law may face significant financial and legal consequences. For example, in Maryland, the secretary of labor has the discretion to impose a civil penalty of up to $10,000 per day. Depending on the circumstances, potential liabilities may include back pay, continuation of employee benefits, civil penalties, mandatory severance under certain state laws, and litigation. Because WARN obligations vary by jurisdiction, maintaining accurate documentation and following both federal and state requirements can help reduce compliance risk during a workforce reduction.
