How Much Notice Must You Give Employees Before Closing?

If you have 100 or more employees, federal law requires you to give at least 60 calendar days’ written notice before closing a business location.{¹} That floor comes from the federal Worker Adjustment and Retraining Notification Act, known as the WARN Act. How much notice you actually need to give employees before closing a business can be longer than 60 days: several states require 90, and a handful cover employers with as few as 25 workers. Smaller businesses exempt from these laws still owe employees final pay, benefits continuation, and any notice their contracts or handbooks promise.

Does the Federal 60-Day Rule Apply to You

The WARN Act applies to private businesses, nonprofits, and quasi-public entities that employ either 100 or more full-time workers, or 100 or more employees whose combined hours (including part-timers) total at least 4,000 per week.{²} Part-time means anyone averaging fewer than 20 hours a week or anyone employed for fewer than six of the last twelve months. Part-timers don’t count toward the 100-employee threshold or toward the number of affected workers that triggers notice.{¹}

For a full shutdown, the triggering event is a plant closing: shutting down an entire employment site (or one or more units within a site) that costs 50 or more full-time employees their jobs within a 30-day window. If you’re closing the whole business and you meet the size threshold, this is almost certainly the definition that applies to you.

Watch the 90-Day Aggregation Rule

Employers sometimes try to duck WARN by staggering layoffs, letting 30 people go one month and another 25 the next. The law anticipates that. If separate rounds of cuts within any 90-day period each fall below the threshold but together hit 50 full-time job losses, WARN treats the whole sequence as a single covered event.{³} The only escape is proving that each round arose from a genuinely separate and distinct cause, which is a hard sell when you’re winding down the same business over a few months.

Practically, if you know you’re closing, don’t assume small batches let you avoid notice. Count every separation over the prior 90 days. If the rolling total hits 50, you likely needed to give notice before the earliest of those layoffs.

When You Can Give Less Than 60 Days

Three narrow exceptions allow shorter notice. None of them eliminate the requirement entirely. You still owe as much notice as circumstances allow, plus a written explanation of why the full 60 days wasn’t feasible.{⁴}

Faltering company. Available only for plant closings. You must have been actively pursuing financing or new business that would have kept the doors open, and you must have reasonably believed announcing the closure would have killed the deal. Courts read this narrowly. A vague hope isn’t enough; you need a concrete prospect.
Unforeseeable business circumstances. Sudden events you couldn’t reasonably have anticipated, such as an abrupt loss of a major contract or a regulatory change that eliminates your market. The test is what a reasonable employer would have foreseen at the time notice would have been due.
Natural disaster. A closure directly caused by a flood, earthquake, drought, or similar event needs no advance notice, though you should still notify employees as soon as possible.

Employers reach for these more often than courts accept them. The faltering company defense in particular fails regularly when the employer wasn’t truly pursuing a specific deal or can’t show that giving notice would have wrecked it. If you think an exception fits, document the specific prospect, the timeline, and why earlier notice wasn’t workable.

Can You Pay Employees Instead of Giving Notice

The WARN Act does not authorize pay in lieu of notice. Providing 60 days of pay and benefits without any advance warning is technically a violation.{⁵} In practice, though, the maximum penalty for a violation is 60 days of back pay and benefits, and voluntary unconditional payments offset that liability. So an employer who pays workers through the full 60-day period has effectively already satisfied the penalty.{⁶}

The catch is that the payment must be voluntary and not already owed. Severance required by an employment contract or collective bargaining agreement does not count toward the offset.{⁵} If your handbook already promises four weeks of severance, that four weeks does not reduce your WARN exposure. You’d pay the WARN amount on top of it.

What the Notice Must Say and Who Gets It

WARN requires separate written notices to three groups: affected employees (or their union representative if they’re organized), your state’s dislocated worker unit, and the chief elected official of the local government where the closing occurs.{¹}

Each employee notice must state whether the shutdown is permanent or temporary, the expected date of closing, the employee’s separation date, whether bumping rights exist (the ability to displace a less-senior worker), and the name and phone number of a company contact.{⁷} If your workforce is unionized, notice goes to the union’s chief officer rather than to each worker individually.

The government notices are more detailed because they’re used to mobilize reemployment assistance. They must include the site’s name and address, the date of first separations, a schedule of any further layoffs, the job titles being eliminated, the number of affected workers in each title, and whether bumping rights exist.

State Laws That Require More

Many states have their own version of WARN, commonly called mini-WARN laws. Some cover businesses with as few as 25 or 50 workers, and a handful require 90 days’ notice instead of 60. Federal WARN does not preempt these; the notice periods run at the same time.{⁷} If your state requires 90 days and federal law requires 60, you owe 90. Check your state labor department before assuming the federal rule is your only obligation. State laws sometimes define triggering events differently too, covering relocations or applying to smaller groups of affected workers, and penalties vary by state.

If Your Business Has Fewer Than 100 Employees

Federal WARN doesn’t apply to you if you’re under the 100-employee threshold.{²} That doesn’t mean you owe nothing. Three things can still require advance warning:

ul>

State mini-WARN laws that cover smaller employers.

Individual employment agreements or handbook provisions that promise a notice period before termination.{}⁷

Collective bargaining agreements requiring advance notice of layoffs. WARN cannot shorten a notice period set by union contract, only extend it.

Even without a legal mandate, giving reasonable notice is worth doing. Blindsided employees are more likely to file complaints with state labor agencies, and sudden closures draw scrutiny from regulators looking for unpaid wages or benefits violations.

Selling the Business Instead of Closing

If you’re selling rather than shutting down, the rules shift. You’re responsible for notice of any closing or layoff up to and including the sale date. After the sale closes, that responsibility passes to the buyer.{⁸} When workers keep their jobs under the new owner, the change of employer isn’t itself an employment loss, so WARN doesn’t apply to the transition. If the buyer plans to eliminate positions soon after closing, though, the buyer owes those workers 60 days’ notice. Make sure the purchase agreement clearly allocates WARN responsibilities between seller and buyer.

Final Paychecks, Benefits, and COBRA

Notice is one piece of a closure. Final pay and benefits have their own deadlines, and some are tighter than WARN’s timeline.

Federal law doesn’t set a deadline for a final paycheck.{⁹} State law does. Deadlines range from the same day as termination to the next regular payday. Since a closure means your payroll function won’t be running much longer, build final paycheck processing into your shutdown timeline. Waiting until employees complain reliably triggers wage claims.

Whether you must pay out accrued, unused vacation or PTO depends on your state and your written policy. In most states, if your policy promises a payout at separation, you’re bound by it. In a few states, payout is mandatory regardless of policy. Review your handbook and state guidance before finalizing your closure budget.

If your business has 20 or more employees, COBRA requires you to offer continuation of group health coverage to affected workers and their dependents.{¹⁰} You have 30 days after the qualifying event to notify your plan administrator, who then has 14 days to send election notices to each qualified beneficiary.{¹¹} A wrinkle for full closures: if the company administered its own group health plan and no longer exists, the plan can effectively terminate with the business, leaving no coverage to continue. Employees in that situation usually turn to marketplace insurance or a spouse’s plan. If you’re winding down gradually, keep the group health plan active long enough to meet your COBRA notice obligations, or work with the insurer on the transition.

Penalties for Failing to Give Notice

The exposure adds up quickly across a large workforce. An employer that fails to give proper notice owes each affected employee back pay and the cost of benefits for every day of the violation, up to 60 days. Back pay is calculated at either the employee’s average rate over the last three years or their final rate, whichever is higher. Liability for any individual employee cannot exceed half the total number of days that person was employed.{⁶}

An employer that fails to notify the local government also faces a civil penalty of up to $500 per day of violation. That penalty can be avoided by paying each affected employee the full amount owed within three weeks of ordering the shutdown. Courts also have discretion to award reasonable attorney fees to the prevailing party, and in a class action brought on behalf of hundreds of workers (the usual form of WARN litigation) those fees can be substantial. The Department of Labor itself does not enforce WARN or investigate complaints. Workers or their unions enforce the law by filing suit in federal court.{⁵}
