Your First Layoff Under 100 Employees: Five Legal Gates Federal WARN Hides

Pre-Flight Gate: Why "Under 100 Employees" Is Never an All-Clear

Founders ask one question before their first reduction: "Are we under 100 employees for the WARN Act?" Stopping research after that yes turns a survival layoff into five separate statutory defaults.

Picture a 62-person software or healthcare services firm cutting 14 roles next Tuesday to extend runway by nine months. An HR-of-one practitioner runs payroll, drafts separation packets, and fields panicked manager questions alone. Nobody on the executive team has run a reduction before.

Execute these five chronological gates in strict sequence during every turning point below 100 total headcount. Do not mail a single invite until Gate 1 through Gate 5 pass verification.

Gate 1: Check State Mini-WARN Thresholds at 25, 50, and 75 Employees

Federal WARN starts at 100 full-time employees, yet half a dozen states pull employer thresholds down to 25, 50, or 75 workers. Missing a 90-day New York notice or 60-day California notice adds two to three months of full back pay per person.

Pull an immediate HRIS headcount export grouped by physical office AND remote home work state. Check your total headcount and planned reduction count against these sub-100 state statutes:

• 25+ employees — Iowa (Iowa Code § 84C.2): Covers employers of 25+ full-time workers; requires 30 days' written notice when laying off 25 or more full-time employees at a single site.
• 50+ employees — New York (NY Lab. Law § 860-a): Covers private employers with 50+ full-time employees in New York; requires 90 calendar days' notice when a layoff at a single site affects 25+ full-time staff representing at least 33% of the site's workforce (or a plant closing affects 25+ full-time staff). Remote employees based at or reporting into the NY site count.
• 50+ employees — Wisconsin (Wis. Stat. § 109.07): Covers employers of 50+ employees in Wisconsin; mandates 60 days' notice when a business closing affects 25+ workers or a mass layoff affects at least 25% of the workforce (minimum 25 employees).
• 75+ employees — California (Cal. Lab. Code § 1400): Covers any industrial or commercial facility employing 75 or more full-time OR part-time persons within the preceding 12 months; requires 60 days' notice for any layoff, relocation, or termination affecting 50 or more employees within a 30-day window (with zero 33%-of-workforce requirement).
• 75+ employees — Illinois (820 ILCS 65/5): Covers employers with 75+ full-time employees; requires 60 days' notice when 25+ full-time employees representing at least 33% of full-time site staff are laid off, or on any plant closing of 50+ full-time staff.
• Multi-entity & Maine check: Confirm whether parent/VC portfolio control creates a single 100+ integrated enterprise, and check Maine (26 M.R.S. § 625-B, 90-day notice on covered facility closings/relocations).

Gate 2: Switch to OWBPA 45-Day Group Waivers Starting at Two Terminations

An "other employment termination program" under the Older Workers Benefit Protection Act starts at just two laid-off employees, not fifty. Reusing your standard 21-day single-exit release renders every age-discrimination waiver unenforceable.

Open 29 U.S.C. § 626(f)(1)(F)(ii) and (H) (covering employers with 20 or more employees under the ADEA) and 29 CFR § 1625.22(f). Whenever you terminate two or more employees under a common reduction—and ask even one departing worker aged 40 or older to waive federal age claims in exchange for severance—three non-negotiable rules replace your individual template:

1. 45 calendar days to consider (not 21 days): Every 40+ employee must receive a full 45 calendar days to review the agreement (employees may sign earlier voluntarily if unpressured, and 29 CFR § 1625.22(e)(6) lets parties agree in writing that immaterial edits do not restart the 45-day clock).
2. 7 calendar days to revoke: An explicit, non-waivable 7-calendar-day revocation window after signing; never disburse conditional severance until Day 8 post-signature.
3. Written decisional-unit disclosure Exhibit B: At the exact start of the 45-day window, attach the class/unit/group definition, eligibility/selection factors, and a complete table listing the exact job titles and exact integer ages (never age bands like "40–49") of every person in the decisional unit selected AND not selected for layoff. Follow our step-by-step OWBPA CSV age-table builder so zero omission voids your releases.

Gate 3: Scrub Selection Criteria for Protected Leave and Adverse Impact

Small cohorts magnify statistical anomalies, and one manager picking "whoever is out right now" triggers strict FMLA and PWFA retaliation claims. Freeze the draft list 72 hours early and verify every single selection reason in writing.

Inside people operations, demand objective, contemporaneous selection records before approving the final 14 names:

• Protected-leave & accommodation firewall: Cross-check every selected name against active or recent FMLA, PWFA pregnancy accommodations, ADA requests, workers' comp, or recent protected whistleblowing/NLRA complaints. Under 29 CFR § 825.216(a) and § 825.220(c), you carry the burden of proving the role would have been eliminated regardless of leave—and if managers used raw ticket or AI output counts, strip leave overlaps first using our metric leave-neutralization protocol.
• Small-cohort adverse impact check: Even when sample sizes are too small for formal chi-square significance, check exact selection rates across age (40+ vs. under 40), sex/pregnancy, race, and disability. If 5 of your 6 employees over age 50 are on a 14-person cut list out of 62 total staff (83% vs. 16%), halt and interrogate every subjective "adaptability" score immediately.
• Visa-holder end-date check: If any selected worker holds H-1B, E-3, or TN status, review our H-1B bona fide termination and 60-day grace-period guide before picking the separation date.

Gates 4 & 5: Same-Day Final Paychecks, COBRA/Mini-COBRA, and State UI Forms

Involuntary layoffs trigger strict discharge-day payroll deadlines—never resignation clocks—plus mandatory state unemployment separation notices. Stage off-cycle payroll, benefits continuation, and master sign-offs 72 hours before notification day.

Lock down Payroll and Benefits execution across Gates 4 and 5:

1. Gate 4 — Involuntary discharge final-pay clocks: A layoff is an involuntary discharge. In California (Lab. Code § 201) and Massachusetts (M.G.L. c. 149, § 148), 100% of earned wages plus all accrued, unused vacation/combined PTO must be delivered on the exact day of termination—never held for the next biweekly payroll run and never reduced for an unreturned laptop (see our final-paycheck PTO and hardware deduction audit). Remember the exempt-salary rule under 29 CFR § 541.602(b)(6): you may prorate an FLSA-exempt employee's salary for the actual days worked in their final week, provided state notice rules allow.
2. Gate 5 — Federal COBRA (20+), State Mini-COBRA (<20), and State UI Separation Packets: If you employed 20+ workers on more than 50% of typical business days in the prior calendar year (29 U.S.C. § 1161), the employer has 30 days to notify the plan administrator and the administrator has 14 days to mail the COBRA election notice (44 days combined when self-administered under 29 CFR § 2590.606-4). Under 20 employees, state mini-COBRA laws (in CA, NY, MA, IL, TX, and 35+ states) govern continuation. Simultaneously attach state-mandated Unemployment Insurance separation notices (such as California DE 2320, New York IA 12.3, New Jersey BC-10, and Massachusetts Form 0590A) inside every Day-0 exit packet.
