A layoff is three legal problems wearing one name. The first is notice: whether the WARN Act or a state mini-WARN statute requires sixty or ninety days' warning, computed from headcount thresholds that are easy to trip and easier to miscount. The second is selection: whether the criteria used to choose who leaves can survive a disparate-impact analysis under the ADEA and Title VII, and whether the employer preserved the privileged adverse-impact study that would tell it in advance. The third is the release: whether the severance agreement actually buys peace, which under the OWBPA requires seven specific elements plus, for group programs, disclosure of the decisional unit with job titles and ages — and which, after McLaren Macomb, cannot carry the broad confidentiality and non-disparagement clauses that severance agreements have contained for decades. This article works through all three, plus the collateral obligations most employers discover late: effects bargaining, COBRA, final pay, accrued vacation, Section 409A, and unemployment insurance. A worked example follows a fictional employer through a 62-person reduction across two states.

In brief. Three questions decide whether a reduction in force is lawful, and they are almost entirely independent of each other. Did notice go out in time? — a headcount-and-calendar question governed by the WARN Act and a patchwork of state statutes that are frequently stricter. Was the selection defensible? — a statistics-and-documentation question governed by disparate treatment and disparate impact law, where the employer's own criteria are the evidence. Does the release work? — a drafting question governed by the OWBPA for employees over forty and, since 2023, by the NLRB's McLaren Macomb decision for the confidentiality and non-disparagement clauses that nearly every severance agreement still contains. An employer can get two of the three right and still face the full litigation it was trying to avoid.
