Ohio’s New Mini-WARN Law: A Guide for Employers

09.09.25 written by

Introduction

On July 1, 2025, Ohio Governor Mike DeWine signed House Bill 96, which, beyond setting the state’s fiscal budget, introduced a new mini-WARN statute, codified as Ohio Revised Code § 4113.31. This law takes effect on September 29, 2025, and imposes additional notice requirements for plant closings and mass layoffs in Ohio. 

  1. Obligations and Coverage

Who Must Comply?

  • Employers with 100 or more employees collectively working at least 4,000 hours per week, excluding overtime, are subject to this law.  

Trigger Events

  • Notice is required when an employer conducts a plant closing or mass layoff involving 50 or more employees at a single worksite during any 30-day period.  
  • Though the law references the federal WARN Act’s definitions for “plant closing” and “mass layoff,” Ohio’s statute omits the federal requirement that layoffs must affect at least 33% of full-time employees and doesn’t clarify whether layoffs should be aggregated across a 90-day period.   
  • This creates ambiguity, and employers should proceed cautiously.  
  1. Notice Requirements: Who Gets Notified and When

60-Day Written Notice Required

Employers must provide at least 60 days’ advance written notice before a covered closing or layoff, mirroring the federal WARN Act. 

Exceptions

  • Ohio law incorporates WARN’s exceptions—including unforeseeable business circumstances, faltering companies, natural disasters, strikes, and lockouts.  
  1. Who Must Receive Notice & What Must Be Included

Ohio’s mini-WARN law imposes expanded notice obligations compared to federal WARN:

A. Union-Represented Employees

Notice to the union must include:

  • Facility location.
  • Detailed reasons for the closing or layoff and whether it’s permanent or temporary.
  • Expected start date and anticipated end date of employment.
  • Number of affected employees, including their job titles/positions and any impacted department or division.

    B. Non-Union (Individual) Employees

Notice must include:

  • Detailed reason and whether the action is permanent or temporary.
  • Start and end dates of layoff or closure.
  • Bumping or reemployment rights (if applicable) and how to exercise them.
  • Information on unemployment benefits, assistance programs, and support services such as retraining, job placement, or counseling.
  • Name, title, and contact details of a company representative for inquiries. 

    C. State and Local Government Officials

Notice must be sent to:

  • The Director of Ohio Job and Family Services,
  • The chief elected officials of both the municipality and county where the layoff/closing will occur.

It must include:

  • All elements listed above for employees/unions.
  • Mitigation efforts (e.g., alternative employment, training programs).
  • Names and addresses of any employee organization (unions).
  • A copy of the employee or union notice.  
  1. Penalties for Non-Compliance

Ohio’s mini-WARN law adopts the federal WARN Act’s remedies, which include:

  • Back pay and benefits for each day of notice not provided (up to 60 days),
  • Possible $500 per day penalties,
  • Reasonable attorneys’ fees in enforcement actions.   

There is no additional penalty imposed by the state beyond federal WARN’s existing enforcement scheme. 

  1. Key Considerations for Employers

Clarify Ambiguities

  • Until guidance is released by the Director of Job and Family Services, uncertainty remains regarding:
    • Whether the 33% threshold applies,
    • Whether layoffs spaced over 90 days should be aggregated,
    • What constitutes sufficient detail for notices, and
    • Whether a single “sample” notice suffices for officials.  

Train Key Personnel

  • Educate HR, legal counsel, and managers involved in workforce reductions on obligations under § 4113.31.

Plan Ahead

  • Develop strategic RIF planning timelines that account for the 60-day lead time and the enhanced notice requirements.   

Seek Legal Guidance

  • Consult employment counsel before any layoff or plant closing to ensure compliance and reduce risk of liability.
