Ohio WARN Act: No State Law, Federal WARN Applies

Ohio has no state WARN Act. Federal WARN governs entirely: employers with 100 or more employees must give 60 days advance notice before a plant closing or mass layoff affecting 50 or more workers. Notice goes to employees, the Ohio Department of Job and Family Services, and the local government.

Ohio has no state WARN Act

Ohio has not enacted a state-level plant closing or mass layoff notification law. Unlike California, New Jersey, New York, or Illinois, Ohio employers are governed exclusively by the federal WARN Act (29 U.S.C. 2101 et seq.). There is no separate Ohio filing form, no Ohio-specific threshold, and no Ohio-only remedy.

Federal WARN applies fully. Ohio employers with 100 or more employees must give 60 days advance written notice before a covered plant closing or mass layoff. Notice goes to affected employees, the Ohio Department of Job and Family Services Rapid Response program, and the chief elected official of the affected local government.

Regional context

Ohio and all of its neighboring states rely on federal WARN only. Pennsylvania, West Virginia, Kentucky, Indiana, and Michigan have each declined to enact a state plant closing law. Illinois, which borders Indiana to Ohio's west, has its own WARN Act with a lower 75-employee threshold. Ohio employers with Illinois operations face different coverage rules.

Federal WARN in Ohio

The federal WARN Act (Worker Adjustment and Retraining Notification Act) requires covered employers to provide 60 days advance written notice before a plant closing or mass layoff. Because Ohio has no state analogue, federal WARN is the only notice obligation Ohio employers face.

Ohio falls within the Sixth Circuit Court of Appeals. Sixth Circuit precedent governs how WARN exceptions and coverage questions are resolved when litigation arises. The Sixth Circuit has addressed WARN disputes involving Ohio's large automotive, manufacturing, and healthcare sectors.

State rapid response agency

Ohio Department of Job and Family Services (ODJFS), Rapid Response program

ODJFS coordinates reemployment services for workers affected by plant closings and mass layoffs. WARN notices in Ohio must be submitted to the ODJFS Rapid Response program as the designated state dislocated worker unit under federal WARN.

Three required notice recipients

  • Affected employees (or union representative)
  • Ohio Department of Job and Family Services, Rapid Response program
  • Chief elected official of the unit of local government where the layoff will occur

Thresholds and triggers

Federal WARN thresholds apply in Ohio without modification. The employer coverage threshold, plant closing trigger, and mass layoff trigger are identical to federal WARN.

Employer coverage threshold

Federal WARN applies to employers with 100 or more full-time employees. Count employees company-wide, not just in Ohio.

Count toward 100

  • Full-time employees (20+ hours/week)
  • Employees on paid leave
  • Employees on temporary layoff with recall rights

Do not count

  • Part-time employees (under 20 hours/week)
  • Employees with fewer than 6 months tenure
  • Independent contractors

Plant closing trigger

A permanent or temporary shutdown of a single site of employment, resulting in employment loss for:

50 or more full-time employees at the affected site

Mass layoff trigger

A reduction in force (not a plant closing) at a single site requires notice if either of these thresholds is met:

Option A

50 to 499 employees

who represent at least 33% of the full-time workforce at the site

Option B

500 or more employees

regardless of percentage of the workforce

Remote workers and Ohio's distributed workforce

Columbus, Cleveland, and Cincinnati are home to significant distributed workforces in insurance, finance, and tech. Remote workers count toward WARN thresholds at their assigned reporting site. A company with a Columbus headquarters and 80 remote employees assigned to that site may cross the 100-employee employer threshold before accounting for any in-office staff.

Does federal WARN apply to your Ohio layoff?

Work through these steps in order. If you answer yes to each, WARN notice is required.

1

Do you have 100 or more employees?

Count full-time employees company-wide. Part-time employees (under 20 hours per week or fewer than 6 months tenure) do not count toward the 100-employee threshold.

Yes: Continue to step 2
No: Federal WARN does not apply.
2

Is the action a plant closing or mass layoff at an Ohio site?

A plant closing is a permanent or temporary shutdown of a single site. A mass layoff is a reduction in force that is not a plant closing. Each site is analyzed independently.

Yes: Continue to step 3
No: Federal WARN does not apply to this action.
3

Does the layoff meet the headcount trigger?

Plant closing: 50 or more full-time employees. Mass layoff: 500 employees, or 50 to 499 employees who represent at least 33% of the site workforce.

Yes: Continue to step 4
No: Federal WARN does not apply unless a separate threshold is met.
4

Does an exception apply?

Three exceptions exist: faltering company (plant closings only), unforeseeable business circumstances, and natural disaster. The Sixth Circuit applies the unforeseeable business circumstances exception narrowly.

Yes: Reduced notice may be permissible. Document the exception in writing.
No: Full 60-day notice is required.
5

Have you notified all three required recipients?

Notice must go to: (1) affected employees or their union, (2) Ohio DJFS Rapid Response, and (3) the chief elected official of the local government where the layoff occurs.

Yes: WARN obligation is met (assuming timely and complete notice).
No: Notice is incomplete. Missing a recipient is a WARN violation.

Who must receive WARN notice in Ohio

Federal WARN requires written notice to three parties. All three must receive notice simultaneously. Missing any recipient is a violation.

1

Affected employees or union representative

Each full-time employee who will experience an employment loss. If employees are represented by a union, notice goes to the chief elected officer of the relevant local. The notice must be specific: position titles, expected date of separation, and whether the action is permanent or temporary.

2

Ohio DJFS Rapid Response program

The Ohio Department of Job and Family Services is the designated state dislocated worker unit under federal WARN. Submit the WARN notice to the ODJFS Rapid Response program so the state can coordinate reemployment services for affected workers.

3

Chief elected official of local government

The mayor, county executive, or equivalent of the unit of local government where the plant closing or mass layoff will occur. For layoffs spanning multiple jurisdictions, notify each relevant jurisdiction.

Exceptions to the 60-day requirement

Federal WARN provides three exceptions that permit reduced notice. None eliminates the notice obligation entirely. The employer must still give as much notice as practicable and state the exception in the notice itself.

Faltering company

Plant closings only

The employer was actively seeking capital or business at the time 60-day notice would have been required, and reasonably believed in good faith that giving notice would have precluded obtaining that capital or business.

Limits

  • Applies only to plant closings, not mass layoffs.
  • The employer must have been actively seeking capital, not merely hoping for investment.
  • The notice must explain that the faltering company exception is being invoked.

Unforeseeable business circumstances

Plant closings and mass layoffs

The closing or layoff was caused by circumstances that were not reasonably foreseeable at the time 60-day notice would have been required, such as a sudden, dramatic, unexpected action by a major customer.

Limits

  • The Sixth Circuit applies this exception narrowly. Circumstances must be sudden and truly unexpected.
  • A predictable revenue decline does not qualify, even if the exact timing was uncertain.
  • Automotive OEM shutdowns do not automatically qualify for suppliers.

Natural disaster

Plant closings and mass layoffs

The closing or layoff was a direct result of a natural disaster: flood, earthquake, drought, storm, tidal wave, or similar event.

Limits

  • The layoff must be a direct result of the disaster, not downstream economic effects.
  • Even with this exception, the employer must provide notice as soon as practicable.

Document shortened notice in writing

Whenever an exception is invoked, the notice itself must state the reason for reduced notice and must be delivered as soon as practicable. Courts in the Sixth Circuit have rejected after-the-fact exception claims that were not reflected in the original notice. If you are relying on an exception, document it contemporaneously and include it in every copy of the notice.

Penalties for violation

Federal WARN penalties are the same in Ohio as in every other state with no additional state law: back pay and benefits liability for each affected employee, plus a civil penalty.

Per-employee liability

Back pay at the employee's regular rate, plus the value of benefits (including medical expenses that would have been covered), for each day of the violation, up to 60 days per employee.

Civil penalty

Up to $500 per day of violation per local government unit. This can be offset if the employer makes voluntary payments to affected employees during the violation period.

Sixth Circuit litigation risk

Ohio automotive and manufacturing employers have faced WARN Act litigation in the Sixth Circuit. Courts in the Sixth Circuit apply the unforeseeable business circumstances exception narrowly. Employers who rely on that exception without solid contemporaneous documentation have faced significant back pay exposure.

Industry notes for Ohio employers

Automotive manufacturing

Ohio is one of the largest automotive manufacturing states. Assembly plants (Honda, Ford, GM, Stellantis facilities) and supplier plants with 100 or more employees are fully covered. A single plant closing or mass layoff involving 50 or more workers triggers the 60-day notice requirement. Suppliers following an OEM shutdown may have shorter effective timelines, but WARN obligations do not shorten with them. The Sixth Circuit applies the unforeseeable business circumstances exception narrowly to supplier claims.

Steel and metals

Ohio's steel industry (Cleveland-Cliffs and others) involves large single-site workforces. Blast furnace shutdowns and production line eliminations regularly cross WARN thresholds. Individual production units at a single site are analyzed as part of that site's headcount, not independently.

Healthcare

Cleveland Clinic, OhioHealth, and other major health systems are among Ohio's largest employers. Facility consolidations and service-line closures affecting 50 or more staff at a single campus trigger WARN. A merger or system integration that eliminates positions across multiple campuses must analyze each campus separately.

Financial services and insurance

Columbus is home to major insurance and financial services headquarters. Companies with 100 or more Ohio employees, across one or multiple Ohio sites, are covered. Each site is analyzed independently. A decision to consolidate two Columbus offices must consider whether the headcount reduction at either location crosses the 50-employee plant closing threshold.

Ohio vs. Illinois WARN

Illinois has its own WARN Act (IL WARN, 820 ILCS 65) with a 75-employee threshold, 25 fewer than federal WARN. Ohio employers with Illinois operations become subject to IL WARN at a lower headcount. The table below shows the key differences.

Frequently asked questions

Does Ohio have its own WARN Act?

No. Ohio has not enacted a state plant closing or mass layoff law. Ohio employers are governed exclusively by the federal WARN Act (29 U.S.C. 2101 et seq.), which requires 60 days advance written notice for covered plant closings and mass layoffs.

Which state agency do I notify for a WARN filing in Ohio?

The Ohio Department of Job and Family Services (ODJFS) Rapid Response program is the state recipient for WARN notices in Ohio. In addition to ODJFS, notice must go to each affected employee (or their union representative) and to the chief elected official of the unit of local government where the layoff will occur.

Does the Sixth Circuit treat WARN exceptions differently?

The Sixth Circuit applies the unforeseeable business circumstances exception narrowly. Employers in Ohio (and other Sixth Circuit states) should not assume that a fast-moving business event automatically qualifies. Courts look for circumstances that were sudden, dramatic, and truly unexpected, not merely a worsening trend the employer was tracking.

Does federal WARN apply to automotive supplier layoffs triggered by an OEM shutdown?

Yes. If you meet the headcount and affected-employee thresholds, your WARN obligation runs on your own timeline, not the OEM's. An automotive supplier that receives short notice from an OEM must still provide 60 days of WARN notice to its own employees if coverage thresholds are met. The unforeseeable business circumstances exception may apply in some cases, but courts in the Sixth Circuit apply it narrowly.

Can a single Ohio distribution center trigger WARN independently of other Ohio locations?

Yes. Each site is analyzed separately under federal WARN. A single warehouse or distribution center with 50 or more affected employees can trigger WARN even if the company has other Ohio locations that are not affected. WARN thresholds are applied at the single site of employment level, not across all of a company's Ohio facilities.
