Indiana WARN Act: Triggers, Notice Rules, and Penalties

The Indiana WARN Act is really the federal Worker Adjustment and Retraining Notification Act applied in Indiana — the state has no separate statute of its own. Employers with 100 or more full-time workers must give at least 60 calendar days’ written notice before a plant closing or mass layoff.¹ In Indiana, the notice is filed with the Department of Workforce Development through its online Employer Portal, and a copy must go to the chief elected official of the local government where the job losses will occur.² Skip the notice or cut it short and the employer owes affected workers back pay and benefits for up to 60 days, plus a possible civil penalty payable to the local government.

Which Employers Are Covered

Coverage turns on headcount. An employer falls under WARN if it employs at least 100 full-time workers, or if it has 100 or more employees (including part-time staff) who together work at least 4,000 hours per week, excluding overtime.³ Meeting either test is enough.

A “part-time employee” for counting purposes is anyone who averages fewer than 20 hours per week or has worked fewer than 6 of the 12 months before notice would be required.³ Part-timers are excluded when deciding whether the employer is big enough to be covered, but they are still entitled to receive notice once a covered event happens.⁴

Nonprofits and quasi-public entities that operate commercially are covered. Regular federal, state, and local government agencies providing public services are not.

What Triggers a Notice

Two types of workforce reductions require notice, and employers need to track both because each has its own thresholds.

Plant Closings

A plant closing happens when an employer permanently or temporarily shuts down a single employment site, or one or more operating units within that site, and 50 or more full-time employees lose their jobs during any 30-day period.⁵ The whole company doesn’t have to close. Shutting one production line or one warehouse at a larger facility can trigger the requirement on its own.

Mass Layoffs

A mass layoff is a workforce reduction that isn’t a plant closing but still produces significant losses at a single site during any 30-day period:⁵

500 or more employees always triggers WARN, regardless of what share of the workforce they represent.
50 to 499 employees triggers WARN only if those workers make up at least 33 percent of the employer’s full-time workforce at the site.
Fewer than 50 does not trigger WARN, even if it wipes out most of a small site.

The 90-Day Aggregation Rule

An employer can’t split a large reduction into smaller rounds to avoid notice. If separate groups of workers are let go over a 90-day window and no single round meets the threshold, the groups are added together. If the combined total would have triggered WARN as a single event, notice is required. The only escape is showing that each round resulted from a distinct cause or business reason, not just the passage of time between announcements.

What Counts as an Employment Loss

Not every separation counts toward these thresholds. The statute defines “employment loss” as a termination other than a firing for cause, voluntary quit, or retirement; a layoff lasting longer than six months; or a reduction in work hours of more than 50 percent during each month of any six-month stretch.⁵ Buyouts and early-retirement packages that workers truly accept voluntarily don’t count. But if a position is eliminated and the employer labels the exit “voluntary,” courts look at whether the worker had any real choice. Substance beats the label on the paperwork.

Who Has to Be Notified

A WARN notice must reach three recipients. Missing any one of them creates liability.¹

Affected employees, or their union. Represented workers get notice through the chief elected officer of the bargaining unit. Unrepresented workers each receive an individual written notice.
The state dislocated worker unit. In Indiana, that’s the Department of Workforce Development.
The chief elected official of local government where the job losses will occur — the mayor, county executive, or equivalent. If the employer pays taxes to more than one local jurisdiction, notice goes to the one receiving the highest tax payments.

What the Notice Must Say

Notices to individual employees must be in plain language and state whether the action is permanent or temporary, the expected first separation date and the specific date the employee will be separated (or a 14-day window), whether bumping rights exist, and the name and phone number of a company contact.⁴ Notices to a union must include the job titles affected and the number of workers in each. Notices to the state and local government must include the employer’s name and address, the nature of the planned action, whether the whole facility is closing, the schedule for separations, and a company contact.

Filing in Indiana

Indiana’s Department of Workforce Development accepts WARN notices through its online Employer Portal, and the filing must land at least 60 calendar days before the first separation date.² On the same timeline, the employer sends a copy to the chief elected official of the local government where the layoffs will occur. These are parallel obligations. Sending one does not satisfy the other.

After a filing comes in, DWD typically coordinates rapid response services for the affected workforce, including on-site orientations covering unemployment insurance, job search help through WorkOne career centers, and information about retraining and continuing health coverage.

Exceptions That Shorten the 60 Days

Three circumstances allow shorter notice. Each is an affirmative defense, so the employer bears the burden of proof. Even when an exception applies, the employer still has to give as much notice as the situation practically allows and attach a written explanation of why the full 60 days wasn’t feasible.¹

Faltering Company

This one applies to plant closings only, not mass layoffs. The employer must have been actively seeking financing or new business when notice was due, had a realistic chance of landing it, and reasonably believed that announcing a potential shutdown would scare the deal away.⁶ Courts read this narrowly. A general hope of finding investors is not enough; the employer needs an identifiable prospect that was realistically within reach.

Unforeseeable Business Circumstances

This exception covers both plant closings and mass layoffs caused by events the employer could not reasonably have predicted when the 60-day clock started: a major client’s sudden cancellation of a contract, an unanticipated government order shutting down operations.⁶ A gradually worsening financial picture doesn’t qualify. The triggering event has to have been genuinely unforeseeable when notice should have gone out.

Natural Disaster

When a closing or layoff is the direct result of a flood, earthquake, storm, drought, or similar natural event, no advance notice is required, though the employer must still send notice as soon as practicable, even after the fact.⁶ The word “direct” matters. A tornado that destroys the facility clearly qualifies. A tornado that disrupts the supply chain and leads to a closure months later does not, though the unforeseeable circumstances exception might.

Pay in Lieu of Notice

WARN has no provision letting an employer substitute 60 days of pay for 60 days of notice. An employer that skips notice and writes checks instead has technically violated the law. But because the penalty is back pay and benefits for up to 60 days, paying workers for the full notice period essentially satisfies the maximum liability.⁷

One trap: the payment has to be above what the employer already owes. Wages promised through a contract, severance agreement, or company policy don’t offset WARN damages. The employer would owe the WARN penalty on top of those contractual amounts.

Business Sales

A sale creates a technical break in employment, but WARN does not treat the sale itself as an employment loss as long as workers keep their jobs with the buyer. Employees of the seller automatically become employees of the buyer for WARN purposes on the effective date of the sale.³

Notice responsibility turns on timing. The seller handles any plant closing or mass layoff occurring up to and including the sale date. After that, the buyer is on the hook.⁸ This creates a hazard in deals where the buyer plans to keep only part of the workforce. Post-sale layoffs may trigger WARN, and the buyer, not the seller, owes the notice.

Remote and Mobile Workers

WARN thresholds measure job losses at a single site, so where a remote worker “belongs” affects the count. Federal regulations assign traveling and field-based employees to the location that serves as their home base, the site that assigns their work, or the site they report to.⁹ That rule was written with bus drivers and salespeople in mind. For employees who work entirely from home and never report to an office, some courts have treated the worker’s residence as the single site, scattering a large remote workforce across many “sites” and making the 50-employee threshold harder to hit at any one. Employers with substantial remote headcount in Indiana shouldn’t assume those workers cluster at corporate headquarters for WARN purposes.

The regulations also handle physical groupings. Separate buildings on a campus or across the street from each other generally count as one site. Non-contiguous buildings in the same area can count as one if they share staff and purpose. Facilities on opposite sides of town with different workers and operations are separate sites, even under common ownership.⁹

Penalties for Noncompliance

An employer that orders a plant closing or mass layoff without proper notice faces two kinds of liability.

First, back pay for each affected worker at the higher of their average rate over the last three years or their final regular rate, plus the cost of benefits (including medical coverage) they would have received during the notice period. This runs for the entire violation period up to a 60-day maximum. There’s a second cap: liability to any one worker cannot exceed half the total days that person was employed there.¹⁰ A worker employed only 40 days before the layoff can recover 20 days of back pay at most, not 60.

Second, failing to notify the local government carries a civil penalty of up to $500 per day of violation. It disappears if the employer pays every affected employee the full amount owed within three weeks of ordering the shutdown or layoff.¹⁰ Miss that three-week window and the civil penalty cannot be avoided.

WARN claims are brought in federal district court. The statute sets no specific filing deadline, so courts borrow the most analogous state limitations period, which varies. Workers in Indiana who believe they were denied proper notice should talk to an employment attorney promptly rather than assuming they have years to act.
