Give the ADEA Waiver Its Full 21-Day Window Before Calling the Severance Signed

The Signal

If a severance agreement asks someone 40 or older to waive age-discrimination claims, the clock on that waiver isn't negotiable, and it isn't 24 hours, and it isn't "sign today, we'll wire tomorrow." Under the Older Workers Benefit Protection Act (OWBPA), 29 U.S.C. § 626(f), a waiver of ADEA rights isn't "knowing and voluntary" — and isn't enforceable — unless the employee gets at least 21 days to consider it, gets told in writing to talk to a lawyer first, and gets a separate 7-day window after signing to revoke it before the agreement can take effect. Skip any one of those pieces and the waiver doesn't partially work. It doesn't work at all. The company can still owe the severance money and still face the age claim it paid to avoid.

Why this matters now

Reductions have been steady this year, and most severance paperwork gets built off whatever template HR used last time, not off a fresh read of what changed. Two things trip people up specifically. First, the 21 days is a floor, not hours — pressuring someone to sign same-day or "by Friday" to lock in a departure date doesn't shorten it, it just makes the waiver void when challenged later. Second, the 7-day revocation period runs after signing, and the agreement "shall not become effective or enforceable until the revocation period has expired" — meaning final paycheck timing, COBRA paperwork, and reference letters tied to a signed severance can all be moving forward against an agreement that isn't actually binding yet.

The mistake to avoid

The mistake is treating the waiver like every other contract clause — something the employee either signs or doesn't, done the moment ink hits paper. OWBPA doesn't work that way. It builds in a cooling-off period on both ends: time to think before signing, time to reverse after. A company that releases final payment, finalizes a neutral reference, or tells a replacement hire to start before the 7-day window closes isn't being generous — it's acting on a waiver that has no legal effect yet, and that gap is exactly what a plaintiff's lawyer looks for first.

The group-termination trap: 21 days becomes 45

The 21-day minimum only applies to an individual departure negotiated on its own. The moment a severance offer goes out to a group or class of employees — a layoff round, a department closure, an "exit incentive program" — the clock extends to 45 days, and a second disclosure obligation kicks in: the company has to tell each person in writing, at the start of that window, who else is eligible or selected for the program, by job title and age, and who in the same job classification or unit was not selected. Companies that reuse an individual-severance template for a group reduction hand out the wrong consideration period and skip a disclosure the statute requires — two separate defects in the same document, both triggered by treating a group event like a one-off.

What stays protected

None of this is about whether the severance amount is fair or whether the business reason for the departure is sound — those stay exactly where they were. What OWBPA protects is narrower and absolute: the employee's actual opportunity to read the agreement, get outside advice, and change their mind, on the statute's timeline, not the company's preferred close date. That's not a negotiable business term. A company can offer more time than the floor; it cannot offer less and call the waiver valid.

The first move

Pull every severance agreement signed in the last 12 months where the departing employee was 40 or older. For each one, check three dates against the actual signature date: was at least 21 days (45 for any group/class reduction) offered to consider it, is there a written "consult an attorney" advisory, and is there an explicit 7-day revocation clause with an effective date that respects it. Flag anything that doesn't have all three in writing — not just "we gave them time," but the dates on paper.

The move this week

For any severance agreement currently in flight, stop and confirm which clock applies before it goes out: individual (21 days) or group/class (45 days, plus the age/job-title disclosure). If it's a group reduction and the current draft only has 21 days built in, fix the template before the first copy goes out — not after someone on day 22 asks why they were only given three weeks.
