How to Lay Off an Employee Legally: WARN Act, Severance, and Final Pay

To lay off an employee legally, you need to select people using documented, objective criteria that don’t disproportionately affect a protected group, give any advance notice federal or state law requires, meet the technical rules for severance releases and benefits continuation, and keep records of every step. Most layoff lawsuits succeed not because the business decision was wrong, but because the process was sloppy: selection criteria no one can explain, a missed WARN Act notice, or a severance waiver that fails a checklist requirement. The walkthrough below covers each obligation in the order you’ll face it.

Anti-Discrimination Laws Apply to Every Layoff Decision

Every federal statute that governs hiring and firing applies to layoffs. Three come up most often when employers get sued after a reduction in force:

Title VII of the Civil Rights Act prohibits selecting employees for layoff based on race, color, religion, sex, or national origin.¹
The Age Discrimination in Employment Act protects workers aged 40 and older. Age-based patterns are among the most heavily litigated claims after large reductions.²
The Americans with Disabilities Act bars discrimination against qualified individuals with disabilities at employers with 15 or more employees.³

Federal law also protects against discrimination based on pregnancy, genetic information, and sexual orientation or transgender status.⁴ If your list ends up disproportionately affecting any protected group, intent won’t save you.

Retaliation Is the Overlooked Trap

If anyone on the list recently filed an EEOC charge, complained about harassment, requested a disability accommodation, or reported a safety issue, expect scrutiny. Federal law prohibits punishing employees for participating in any EEO process. Courts treat close timing between protected activity and a layoff as strong evidence supporting an inference of retaliation.⁵ You can still include that employee in a legitimate reduction, but the documentation needs to be airtight. Have counsel review the file before the decision is final.

Build Selection Criteria You Can Defend

Selection criteria are the single most important piece of evidence when a layoff is challenged. Document them before any names go on a list, and make them specific enough that two managers applying them independently would reach similar results.

Defensible criteria rely on measurable factors: documented performance ratings, specific skills required for the roles that remain, seniority within the affected department, or the elimination of an entire function. Criteria that lean on subjective judgment, such as “cultural fit” or “leadership potential” without supporting metrics, invite challenge because they leave room for unconscious bias to shape the outcome.

Written records from any prior performance improvement plan are valuable. Evidence that an employee received a fair warning and specific goals undercuts a later claim that the layoff was pretext. If performance was not the documented reason for selection, don’t introduce it retroactively as justification.

Run a Disparate Impact Check Before Anyone Is Notified

Facially neutral criteria can still produce a list that disproportionately hits older workers, women, or another protected class. Compare the demographics of the people selected against the demographics of those who were not, and do it before you finalize anything.

The EEOC’s guidance on age-related disparate impact identifies the factors that determine whether a process was reasonable: how closely the criteria relate to the stated business purpose, whether managers received clear guidance on applying them, whether subjective discretion was limited, and whether the employer actually assessed adverse impact on protected groups.⁶

Large employers that already use software to monitor workforce demographics for race and sex disparities would be acting unreasonably if they failed to run the same analysis for age. Smaller employers without those tools can meet the standard through informal methods, such as manually reviewing the list broken down by age bracket, gender, and race.⁶ If the numbers skew badly, revisit the criteria or adjust selections before anyone hears about it.

Check Contracts That Limit Your Discretion

Before applying selection criteria, look at what you’ve already agreed to. Collective bargaining agreements almost always dictate the order of layoffs (usually by seniority), recall rights, and severance terms. Deviating from those provisions exposes you to a grievance and potentially an unfair labor practice charge.

Individual employment agreements, especially for executives, may specify notice periods, guaranteed severance, or other terms that override your standard process. If a contract calls for 12 months of severance and you offer six, the contract wins. Review every affected employee’s agreement before you announce anything.

WARN Act: When You Must Give 60 Days’ Notice

The Worker Adjustment and Retraining Notification Act requires covered employers to give affected workers at least 60 calendar days’ written notice before a plant closing or mass layoff. Notice also has to go to employee representatives (such as a union) and to state and local government officials.⁷

Who Is Covered

You’re covered if you employ either 100 or more full-time workers (excluding those with under six months’ tenure or averaging under 20 hours per week), or 100 or more employees including part-timers who together work at least 4,000 hours per week.⁸ Private for-profit businesses, nonprofits, and quasi-public entities all fall under the law.

What Triggers the Notice

A “mass layoff” is a reduction at a single site that results in job losses for 500 or more employees (excluding part-timers), or for 50 to 499 employees if that group makes up at least one-third of the active workforce at the site.⁷ A plant closing triggers the requirement when a shutdown at a single site causes 50 or more job losses within a 30-day period. Many states have their own versions with lower thresholds, longer notice, or broader triggering events. Check yours.

Penalties

An employer that violates WARN owes each affected employee back pay and the value of lost benefits for every day of the violation, up to a maximum of 60 days, and the liability cannot exceed half the total days the employee worked for you. On top of that, the employer faces a civil penalty of up to $500 per day payable to the affected local government, though you can avoid the penalty by paying each employee within three weeks of ordering the layoff.⁹ Courts may also award attorney’s fees to prevailing plaintiffs.

Narrow Exceptions to the 60 Days

Three exceptions permit shorter notice. The “faltering company” exception applies only to plant closings, where the employer was actively seeking financing and reasonably believed that giving notice would have killed the deal.¹⁰ The “unforeseeable business circumstances” exception covers situations the employer could not reasonably have predicted, such as the sudden loss of a major contract. A natural disaster exception applies when a closing or layoff results directly from a flood, earthquake, or similar event. In all three cases, you still have to give as much notice as is practicable and explain in writing why the full 60 days wasn’t possible.

Severance Agreements and OWBPA Compliance

Severance pay isn’t legally required in most situations. But when you offer it in exchange for a release of claims, the agreement has to satisfy strict requirements or the release won’t hold up. The stakes are highest with workers aged 40 and older, where the Older Workers Benefit Protection Act adds specific conditions.

For a waiver of age discrimination claims to count as knowing and voluntary, it must meet all of the following:

Written in plain language, understandable to the person signing it or to an average eligible participant.
Specific reference to rights under the ADEA.
No waiver of claims arising after the date of signing.
Consideration beyond what the employee was already entitled to.
Written advice to consult an attorney.
At least 21 days to review for an individual layoff, or at least 45 days if the waiver is part of a group layoff or exit incentive program.
At least 7 days after signing to revoke, with the release not effective until the revocation period expires.¹¹

Group layoffs carry an extra disclosure requirement. At the start of the consideration period, you must provide each eligible employee with a written description of the group covered by the program, the eligibility factors and time limits, and the job titles and ages of all individuals eligible or selected for the program alongside the ages of those who were not.¹¹ Miss any of these and the age-claim waiver is void. The employee keeps the severance and can still sue.

Severance itself is treated as supplemental wages for federal tax purposes, and structured plans that spread payments over time can implicate Section 409A of the Internal Revenue Code. A noncompliant plan makes the employee owe tax on the full deferred amount plus a 20% additional tax.¹² Have a tax professional review any structured severance before it goes out.

Final Pay, COBRA, and Other Benefits

Final Paychecks

Final pay should include accrued unused vacation (where your policy or state law requires payout), commissions, bonuses owed, and any other outstanding compensation. Deadlines vary significantly by state, from immediate payment on the termination date to several days later. Getting the timing wrong creates wage-claim liability on top of whatever the layoff itself might produce. Check your state labor department’s rules before the layoff date.

COBRA Notices

COBRA applies to employers that maintained a group health plan and had at least 20 employees on more than half of their typical business days in the prior calendar year.¹³ A layoff is a qualifying event that entitles the employee and their covered dependents to continue group coverage at their own expense, typically for up to 18 months.

The timeline is tight. Notify your plan administrator of the qualifying event within 30 days. The plan administrator then has 14 days to send an election notice to each qualified beneficiary. If you serve as your own plan administrator, the election notice must reach the employee no later than 44 days after the qualifying event.¹⁴ Missing these deadlines exposes you to excise taxes and lawsuits from employees who lost the chance to elect coverage.

Retirement and Equity

Give clear information about retirement plan balances, stock options, and any other employer-sponsored benefits. Vested 401(k) balances stay with the employee, but unvested employer contributions may be forfeited depending on plan terms. If stock options have an accelerated exercise window after termination, the employee needs to know the deadline.

Protect Trade Secrets and Cut Digital Access

The federal Defend Trade Secrets Act gives employers the right to seek injunctions and damages when a trade secret related to interstate commerce is misappropriated. Remedies include actual losses, unjust enrichment, and, in cases of willful misappropriation, exemplary damages of up to twice the actual damages.¹⁵ A court cannot use this statute to prevent someone from taking a new job; injunctions must rest on evidence of threatened misappropriation, not merely on what the person knows.

On non-competes, the FTC’s attempted federal ban was formally removed from the Code of Federal Regulations effective February 12, 2026, after federal courts struck down the rule and the Commission dropped its appeals.¹⁶ Enforceability depends entirely on state law, and several states restrict or ban non-competes. Review existing agreements with counsel before relying on them.

Revoke digital access at the moment of the layoff notification, not afterward. Disable the employee’s accounts through your identity provider or single sign-on system, revoke access to individual tools like messaging platforms and cloud storage, force a logout of active sessions across browsers and mobile devices, and shut down VPN and internal network access. If a company laptop or phone can’t be collected immediately, initiate a remote wipe.

Conducting the Layoff Meeting

Keep the meeting short, direct, and respectful. The employee’s direct manager should deliver the news, with an HR representative present to handle questions about benefits and next steps and to serve as a witness.

Cover the essential facts: the effective date, the reason the position is being eliminated (framed as a business decision, not a performance critique unless performance was the documented and non-discriminatory basis for selection), final pay timing, COBRA rights, and how to return company property. Hand the employee a written summary of everything discussed. People in this situation retain very little of what they hear.

Resist the urge to over-explain. Lengthy justifications create room for inconsistency across meetings, and inconsistency is what plaintiffs’ attorneys exploit. Stick to the script, answer direct questions honestly, and mention any outplacement services or employee assistance program without turning the meeting into a pitch.

After the Layoff

Unemployment Insurance

When the state unemployment agency asks for separation information, respond promptly and accurately. A laid-off employee is generally eligible because the separation wasn’t their fault. Contesting a valid claim rarely succeeds and creates unnecessary friction with someone who might otherwise move on quietly. Layoffs also feed into your state unemployment tax rate under most states’ experience-rating systems, so the cost can extend for years after a large reduction.

Record Retention

Keep everything: the selection criteria and disparate impact analysis, the WARN notice if applicable, every signed severance agreement, the COBRA notice, and your notes from each meeting. Title VII and ADA charges must generally be filed with the EEOC within 180 to 300 days, but ADEA claims and breach-of-contract disputes can surface later. Contemporaneous documentation is your best defense if a claim shows up a year after the fact.

Communicating With Remaining Employees

The employees who stay will watch closely. If the process looked arbitrary or secretive, expect a drop in morale and voluntary departures among your best performers. A brief, honest communication about what happened and why, without disclosing individual details, helps maintain trust with the people you kept.
