A resource map covering the full range of separations, from a single for-cause termination to a multi-state plant closing. Twelve pillars treat the decision architecture that determines which body of law applies, the WARN counting rules and the state mini-WARN patchwork that usually controls, selection criteria and the hierarchy of defensibility, disparate impact under Title VII and the ADEA including the employer's burden to prove a reasonable factor other than age, the adverse impact analysis and its privilege problem, the protected-status screen, severance design and its interaction with WARN offsets and ERISA plan status, the OWBPA including the group decisional-unit disclosure and the no-tender-back rule of Oubre, the post-McLaren Macomb limits on confidentiality and non-disparagement, the collateral obligations from effects bargaining through Section 409A and COBRA, individual terminations and the performance-management record that makes them defensible, and the post-separation questions of recall, rehire, and references. Appendices provide a nine-week project timeline, a separation-agreement clause inventory, and the seven failures that account for most litigation.

Labor and Employment > Termination and Layoffs | Published 4 April 2026 - Updated 26 June 2026 | UpLaw - uplaw.us

Every separation raises the same three questions, and the size of the event only changes which ones can hurt you. Was notice required, and was it given? Can the selection be explained with documents that existed before the decision? Does the release actually buy peace? A single for-cause termination usually implicates only the second. A sixty-person reduction across two states implicates all three, on three different clocks, and the notice clock runs backward from the date the business wants to announce.

How to read this toolkit

Twelve pillars, each with the governing doctrine, the anchor authority, the trap, and links to the documents that go deeper. Three ground rules.

One: sequencing is the whole game. Notice statutes run backward from the announcement date. Selection criteria must exist in writing before names are collected. Both mean the legal work has to be finished before the business feels ready.

Two: the state analysis is usually the operative analysis. Federal WARN's 33 percent test makes it inapplicable to many large-sounding layoffs; several state statutes have no percentage test at all. The most common WARN class action follows a correct federal analysis and no state analysis.

Three: severance is the employer's purchase of peace. If the release does not hold, the employer has funded its opponents. Two rules make that easy to get wrong — Oubre (a defective OWBPA waiver bars nothing and the employee keeps the money) and McLaren Macomb (the confidentiality and non-disparagement clauses in almost every template are unlawful to offer).

Our running employer. Halvard Systems, Inc. (fictional), 1,240 employees, industrial software. Eliminating 62 positions across two sites in two states, sixteen weeks after a separate 9-position action.

Pillar 1 — Decision architecture: which law applies

Doctrine. Separations fall on a spectrum, and where an event sits determines the legal apparatus:

Event Notice law Selection law Release law
Single for-cause termination None Disparate treatment; contract Optional release; OWBPA if 40+
Small group reduction Usually none federal; check state Treatment + impact OWBPA 21 days if individual
Reduction hitting WARN thresholds Federal WARN + state Treatment + impact + statistics OWBPA 45 days + group disclosure
Plant closing / site shutdown Federal WARN + state; effects bargaining Usually function-based Same as above
Sale of business WARN allocation by closing date Buyer's selection rules Deal-allocated

Trap. Employers treat a 30-person reduction as a routine set of individual terminations, so nobody computes anything. But a 30-person reduction offered a common severance package is an "exit incentive or other employment termination program offered to a group or class" under the OWBPA, triggering the 45-day period and the group disclosure. The threshold for the group-program rules is not the WARN threshold, and it is much lower than employers assume.

Pillar 2 — WARN: the counting rules

Doctrine. Sixty days' written notice of a plant closing (50+ employment losses at a single site, or from shutdown of a facility or operating unit within a site, in any 30-day period) or a mass layoff (500+, or 50–499 constituting 33%+ of active employees at the site), for employers with 100+ employees excluding part-time. 29 U.S.C. §§ 2101–2109; 20 C.F.R. Part 639.

Employment loss includes a termination, a layoff exceeding six months, and a reduction in hours over 50% in each month of any six-month period. § 2101(a)(6).

Anchors. The 90-day aggregation rule, § 2102(d) — sub-threshold losses within any 90 days aggregate unless the employer proves separate and distinct actions and causes. The three exceptions (faltering company, plant closings only; unforeseeable business circumstances; natural disaster), each requiring notice as soon as practicable plus a written statement of the basis for reduced notice. § 2102(b). Remedies capped at 60 days' back pay and benefits, further capped at half the days employed, with no injunctive relief. § 2104.

Four traps.

  1. Remote workers are assigned to the site to which they report or from which work is assigned. 20 C.F.R. § 639.3(i). Fifty-five remote employees reporting to headquarters can be a plant closing there.
  2. The 90-day rule runs forward as well as backward. A reduction planned for next quarter can retroactively convert this one into a covered event.
  3. Furloughs that slip past six months create an employment loss, and notice was due 60 days before the original date.
  4. The reduced-notice statement is omitted routinely, forfeiting the exception the employer thought it had.

Halvard. 44/310 and 18/96, separate sites, prior action outside 90 days. Federal WARN not triggered — a correct conclusion, and precisely the point at which most employers stop working.

Pillar 3 — The state mini-WARN patchwork

Doctrine. A substantial and growing group of states impose their own notice regimes, generally stricter. They differ on employer size threshold, event threshold and whether any percentage test applies, whether measurement is per site or employer-wide, notice period (60, 90, or other), coverage of relocations, whether severance is mandated by statute, which exceptions are recognized, notice recipients and prescribed forms, penalties, and whether officers face individual liability.

Trap. Attempting a single national timeline. Build a matrix — one row per site, one column per requirement — comply with the most protective rule at each site, and set the announcement date from the longest applicable notice period. Verify current statutory text; these change frequently.

Pillar 4 — Selection criteria: the hierarchy of defensibility

Doctrine. In descending order: elimination of a function, position, or business line; objective pre-existing performance data; skills assessment against a written future-state specification applied by a panel using a rubric; meaningful prior performance ratings; seniority; manager discretion with contemporaneous written justification.

Anchor. Not a case — the dated document stating the criteria, created before any names are collected. Metadata establishes the sequence in discovery, which cuts for the employer when the order is right.

Traps. Three.

"Identify your lowest performers by Friday" is not a criterion. It is a request for undocumented preference, and it is the most common instruction in American layoffs.

Compensation cost as a criterion correlates strongly with age and tenure. "Reduce the highest-cost positions" is an age-impact machine.

Benefit proximity is worse than a proxy — selecting to prevent vesting independently violates ERISA § 510, 29 U.S.C. § 1140, and it is the limit on the otherwise employer-friendly holding of Hazen Paper Co. v. Biggins, 507 U.S. 604 (1993), that pension status is analytically distinct from age.

Also required: calibration across managers. Twelve managers applying one criterion in twelve ways produces the appearance of pretext even where each acted in good faith. And score the whole decisional unit, not just the departing — a record that scores only the selected cannot support a comparative defense.

Pillar 5 — Disparate impact, and the ADEA's distinctive burden

Doctrine. Title VII: the plaintiff identifies a practice causing impact; the employer must demonstrate it is job related and consistent with business necessity; the plaintiff may show a less-impactful alternative the employer refused. 42 U.S.C. § 2000e-2(k). Subjective criteria are subject to impact analysis. Watson v. Fort Worth Bank & Trust, 487 U.S. 977 (1988).

ADEA: impact claims are cognizable — Smith v. City of Jackson, 544 U.S. 228 (2005) — but the statute supplies a reasonable factor other than age defense, and the employer bears the burden of pleading and proving it. Meacham v. Knolls Atomic Power Laboratory, 554 U.S. 84 (2008). See the RFOA considerations at 29 C.F.R. § 1625.7.

For disparate treatment under the ADEA, the plaintiff must prove age was the but-for cause. Gross v. FBL Financial Services, Inc., 557 U.S. 167 (2009).

Trap. Meacham is the sleeper. In a layoff with statistically significant age impact — which is most layoffs, since older employees are often more senior and concentrated in legacy work — the employer must affirmatively prove a business rationale. That record has to be built while deciding, not reconstructed in litigation.

Halvard. Selected group's mean age 51 against a workforce mean of 38, statistically significant. The driver is a legacy product line wind-down staffed by long-tenured engineers. That is a genuine RFOA — if Halvard can document which product, when the retirement decision was made, who staffed it, and that the criterion was the product line rather than tenure. Without documents, the numbers speak alone.

Pillar 6 — The adverse impact analysis and its privilege problem

Doctrine. Before the list is final, compute selection rates by decisional unit for age 40+, sex, race and ethnicity, and disability status where known. Apply the four-fifths rule of thumb (Uniform Guidelines, 29 C.F.R. Part 1607) and a test of statistical significance.

Where impact appears, choose consciously among three legitimate options: change the criteria, change the list, or document the justification and accept known risk.

Trap. The privilege collapse. Counsel directs the analysis for legal advice; someone puts the summary chart in the steering-committee deck; privilege is gone. And note the deeper tension: relying on the analysis to establish good faith may waive privilege over it anyway. Decide the purpose at the outset rather than discovering the question in a deposition.

What is worse than not running it: running it, finding impact, changing nothing, and having no explanation.

Pillar 7 — The protected-status screen

Doctrine. Before locking the list, identify anyone on FMLA or other protected leave; with a pending ADA or PWFA accommodation request; a recent complainant or charging party; a workers' compensation claimant; a whistleblower under SOX, Dodd-Frank, the False Claims Act, or a state analogue; on military leave; on an employment-based visa; pregnant or recently on parental leave; or engaged in protected concerted activity.

Trap. Two opposite errors. Exempting people because of protected status creates reverse-discrimination exposure and implies the employer thought the reduction was unlawful. Ignoring status leaves the employer unable to explain temporal proximity. The correct posture is neither — it is documented equal treatment, ideally with records predating the protected activity.

The hardest case: an employee on protected leave whose position is eliminated. Permissible where the position would have been eliminated regardless, but the employer bears the burden and pre-leave documentation is the only persuasive evidence.

Pillar 8 — Severance design

Doctrine. Formula (weeks per year, floor and cap), applied consistently by level. COBRA subsidy. Outplacement. Accrued vacation per state law. Equity treatment.

Two structural decisions.

WARN offset. Voluntary, unconditional payments not otherwise legally owed can offset WARN liability; payments conditioned on a release generally cannot. § 2104(a)(2). An employer that conditions all severance on a release may forfeit the offset it thought it had.

ERISA plan status. A one-time lump sum triggered by a single event, requiring no ongoing administrative scheme, generally is not an ERISA plan. Fort Halifax Packing Co. v. Coyne, 482 U.S. 1 (1987); see also Massachusetts v. Morash, 490 U.S. 107 (1989). A recurring program with eligibility criteria and discretionary determinations may be. Plan status brings SPD and claims-procedure obligations — and deferential review plus preemption of state contract claims. An employer that wants deference may prefer plan status. Choose deliberately.

Trap. § 409A. Conditioning payment on return of a release, where the consideration-plus-revocation window straddles two tax years, lets the employee choose the payment year — a § 409A failure whose 20 percent additional tax falls on the employee. Fix it with a fixed payment date after the revocation period, regardless of when the release comes back.

Pillar 9 — The OWBPA

Doctrine. 29 U.S.C. § 626(f); 29 C.F.R. Part 1625, Subpart B. Seven elements: plain language; specific ADEA reference; no waiver of post-execution claims; additional consideration; written advice to consult counsel; 21 days to consider (45 for a group program); 7 days to revoke with delayed effectiveness.

Group program disclosures, § 626(f)(1)(H): the decisional unit, eligibility factors, time limits, the job titles and ages of all eligible or selected, and the ages of all not eligible or selected in the same job classification or organizational unit.

Anchor. Oubre v. Entergy Operations, Inc., 522 U.S. 422 (1998): a non-compliant waiver cannot bar an ADEA claim, and the employee need not tender back the consideration. No ratification doctrine exists. The employer has paid and bought nothing on the age claim.

Traps. The decisional unit does double duty — it frames the statistical analysis and defines the disclosure — so use one definition for both; employers who use different units have created an inconsistency a plaintiff's expert will exploit. The disclosure is functionally a compelled adverse-impact exhibit delivered to every employee over forty, which is why the impact analysis belongs earlier in the sequence. And note the partial consolation: the OWBPA governs only ADEA claims, so a defective age waiver may still release Title VII, ADA, FMLA, and state claims if otherwise valid.

Pillar 10 — What a release cannot do, and McLaren Macomb

Never waivable, however drafted:

  • The right to file an EEOC charge or participate in an investigation (monetary recovery may be waived; the right to file may not). 29 C.F.R. § 1625.23.
  • Communication with a government agency or receipt of a whistleblower award. SEC Rule 21F-17 prohibits impeding communication with the Commission, and the SEC has brought enforcement actions over restrictive severance language.
  • Vested benefits, unpaid wages, and in most states workers' compensation and unemployment claims.
  • Prospective FMLA rights. 29 C.F.R. § 825.220(d).
  • Pre-dispute NDAs and non-disparagement clauses covering sexual assault or harassment disputes. Speak Out Act, 42 U.S.C. § 19401 et seq.; see also 26 U.S.C. § 162(q) denying deductions for confidential harassment settlements.

McLaren Macomb, 372 NLRB No. 58 (2023): offering a severance agreement with overly broad confidentiality or non-disparagement provisions violates § 8(a)(1), because such provisions restrain § 7 rights.

Operational points: § 7 applies in non-union workplaces; the offer is the violation, not just enforcement; genuine supervisors under 29 U.S.C. § 152(11) are outside it but the definition is narrower than employers assume; and a savings clause alone does not cure an overbroad provision.

Drafting response. Narrow confidentiality to the financial terms rather than the existence and all terms. Narrow non-disparagement to maliciously false statements. Add a prominent affirmative carve-out for protected concerted activity, coworker discussion of wages and working conditions, agency charge-filing and communication, and lawful subpoenas. Re-verify current Board doctrine before finalizing a template — this area moves with the Board's composition.

Pillar 11 — The collateral obligations

Effects bargaining. Required for represented employees even where the decision is not a mandatory subject. First National Maintenance Corp. v. NLRB, 452 U.S. 666 (1981); compare Fibreboard Paper Products Corp. v. NLRB, 379 U.S. 203 (1964). Announcing before satisfying the obligation is a routine unfair labor practice. On a sale, add successorship: NLRB v. Burns International Security Services, 406 U.S. 272 (1972); Fall River Dyeing & Finishing Corp. v. NLRB, 482 U.S. 27 (1987).

ERISA § 510. No discharge for the purpose of interfering with benefit attainment. 29 U.S.C. § 1140.

COBRA. Notices on the statutory timeline. 29 U.S.C. §§ 1161–1169.

§ 409A. Short-term deferral or separation-pay exemption; fixed payment date.

Final pay and vacation. State deadlines, often immediate on involuntary termination, sometimes with waiting-time penalties. See Wage and Hour Law Under the FLSA: A Comprehensive Guide.

Unemployment. Severance may delay or offset benefits by state characterization. Do not guess in employee communications.

Immigration. Grace periods, portability, and employer notification for visa holders. See Employment-Based Immigration: A Comprehensive Guide to H-1B, O-1, and EB Visas.

Equity. Vesting acceleration, post-termination exercise windows (an ISO extended past 90 days becomes an NSO), and repurchase rights — the most frequent source of post-layoff disputes. See Founder Equity, Vesting, and the 83(b) Election: A Practical Checklist.

Trade secrets. Departing employees take information. Build the exit protocol before the announcement. See Protecting Trade Secrets When Employees Leave: A Practical Checklist and The Trade Secret Litigation Toolkit.

Pillar 12 — Individual terminations, and the record that makes them defensible

Doctrine. No notice statute applies, and at-will employment is the default in nearly every state — but at-will means the employer needs no reason, not that any reason will do. The defense to an individual termination is a contemporaneous performance record.

What a defensible individual termination file contains: a written performance expectation the employee received; documented specific instances of failure to meet it, dated at the time; documented coaching or warning; consistency with how comparable employees were treated; and a decision-maker who can articulate the reason without reference to protected characteristics.

Traps.

  • The unblemished file. Managers avoid difficult reviews, rate everyone "meets expectations," and then terminate abruptly. The resulting record shows six years of adequacy and one sudden termination, and the employer's only witness is the manager's memory.
  • The pretext of recency. Documentation created in the two weeks before termination, after a protected complaint, is worse than no documentation.
  • The inconsistent comparator. Someone else did the same thing and was coached. Find that person before the plaintiff does.
  • The OWBPA still applies to an individual release from an employee 40 or over: 21 days and 7 days to revoke.

This toolkit is educational and is not legal advice. State mini-WARN statutes vary substantially and change frequently; NLRB doctrine on severance-agreement provisions shifts with the Board's composition; and Section 409A, ERISA, and state final-pay and vacation rules add jurisdiction-specific requirements. Confirm current federal and state law before executing any separation program.
