Severance Agreement Red Flags: OWBPA's 21-Day Window, the 7-Day Revocation Period, and the Three Releases You Can't Actually Waive

The HR director closes the door, slides a ten-page packet across the conference table, and tells you to take a few days but no later than Friday. Inside the packet: eight weeks of severance, continued health insurance through the end of the month, and a release of "any and all claims" against the company "known or unknown, past, present, and future."

You are forty-three. You have a vague sense that there is supposed to be a 21-day window for this. You don't know what OWBPA stands for. The HR director has done this 200 times. You have done it once.

That asymmetry is what severance agreement red flags are built on. The good news: federal law caps how badly that asymmetry can play out. Most severance agreements are written assuming you do not know the law. Reading them in the right order, with the right framework, changes the leverage.

TL;DR

• OWBPA (29 U.S.C. § 626(f)) governs every severance that includes an ADEA waiver, which is every severance for anyone over 40. It requires 21 days to consider individually, 45 days for group programs, and a separate 7-day revocation window after signing.
• Three categories of claims cannot be waived even with a signed release: unpaid wages under the FLSA, workers' compensation claims, and future claims that have not yet arisen.
• McLaren Macomb (NLRB, February 2023) held that overly broad non-disparagement and confidentiality clauses in severance agreements violate NLRA Section 7. Many 2022-era severance forms are now unenforceable on this point.
• "Sign by Friday" is almost always a negotiating tactic, not a real deadline. OWBPA's 21-day window runs from the date the employer presented the agreement, not from when the employee chooses to sign.
• The biggest dollar items to negotiate are not the headline severance number: extended COBRA subsidy, accelerated equity vesting, and a neutral reference letter often outweigh an extra 2 weeks of pay.

The 21/45-day window (OWBPA § 626(f)(1)(F))

If you are over 40 and the agreement asks you to release age-discrimination claims, federal law gives you a minimum window to consider it.

The individual is given a period of at least 21 days within which to
consider the agreement; or, if the waiver is requested in connection
with an exit incentive or other employment termination program offered
to a group or class of employees, a period of at least 45 days within
which to consider the agreement.

Three things this paragraph does that most readers miss:

1. The window is a floor, not a ceiling. The employer cannot force you to sign sooner than 21 days. The employer can absolutely give you 30 or 60 if you ask.

2. Group layoffs trigger 45 days. If your termination is part of a reduction-in-force, OWBPA also requires the employer to disclose the job titles and ages of everyone in the decisional unit, both selected and not selected. Most layoff packets include this as an attachment titled "Schedule A" or "Disclosure." Read it. Disparities are how age-discrimination claims start.

3. The window runs from presentation, not from signature. If HR hands you the packet on Monday and you sign Wednesday, you have used 2 of your 21 days, not all 21. You can take the rest. There is no penalty for using the full window.

A High risk clause is one that says "by signing below, you acknowledge you have had at least 21 days" when you've had four. Strike it. The acknowledgment does not make the underlying violation go away. OWBPA is not waivable.

The 7-day revocation period (§ 626(f)(1)(G))

After you sign, you have seven calendar days to revoke. The agreement is not enforceable until the revocation period expires. This is also unwaivable.

What this means in practice: if you sign Friday and on Tuesday morning you find a recruiter's offer, an attorney, or a posting that suggests age discrimination in the layoff selection, you can revoke. The revocation must be in writing, delivered to the contact named in the agreement, and postmarked or received within seven days.

The cost: severance payments scheduled to begin during the 7-day window are paused until day 8. Almost every agreement structures it that way. Don't let HR tell you the revocation period is "just a formality." It is the only window where the leverage shifts back.

The three releases you can't actually waive

Severance agreements typically include catch-all release language: "any and all claims known or unknown, past, present, and future, of any kind whatsoever." That language is mostly enforceable. Three categories punch through.

1. Unpaid wages under the FLSA. Federal courts have held since Lynn's Food Stores v. United States (11th Cir. 1982) that FLSA wage claims cannot be waived by private agreement without DOL or court supervision. If you are owed overtime, unpaid commissions, or final-paycheck wages, the release does not extinguish them. State wage-and-hour claims often follow the same logic, especially in CA, NY, MA, and WA.

2. Workers' compensation. Every state's workers' comp statute makes private waiver of comp benefits void. If you have a pending injury or one that surfaces post-termination, the release will not block the claim.

3. Future claims that have not yet arisen. A release can extinguish claims that exist on the date of signing. It cannot reach forward to events that have not happened. If your former employer leaks your medical records six months after termination, the prior release does not protect them. State courts vary on the edges, but the rule is consistent.

A clean release will explicitly carve these out, often as "Excluded Claims." If yours doesn't, the carve-out applies anyway as a matter of law, but the silence is a tell. It tells you the agreement was drafted to maximize what the employer could plausibly extract.

McLaren Macomb: non-disparagement is no longer free

In McLaren Macomb (NLRB, February 21, 2023) the National Labor Relations Board held that overly broad non-disparagement and confidentiality clauses in severance agreements violate Section 7 of the NLRA, which protects employees' rights to discuss terms and conditions of employment, including with former coworkers, the press, government agencies, and unions.

What this means in practice:

Non-disparagement clauses that prohibit you from making any negative statement about the employer for any reason, in any forum, are now likely unenforceable for non-managerial employees. Narrowly tailored versions, those limited to false or defamatory statements, are still likely valid.

Confidentiality clauses that bar you from discussing the existence or terms of the agreement with anyone are likely unenforceable. Versions that allow disclosure to spouse, attorneys, accountants, and government agencies survive.

If your severance still has the old broad language, that is not just a negotiating point. It signals the employer's HR has not updated its forms in two-plus years, which is a signal about a lot of other things.

Confidentiality and non-disclosure

Most severance includes a confidentiality term covering trade secrets, customer lists, and pricing. That is reasonable and enforceable. What is not reasonable: a clause that defines "confidential information" so broadly that it covers your own pay history, performance reviews, and the existence of your job. Strike or narrow.

The federal Defend Trade Secrets Act (18 U.S.C. § 1833(b)) also requires every confidentiality agreement to include an immunity notice for whistleblower disclosures to government officials and attorneys. Most don't. The omission costs the employer the ability to recover punitive damages and attorney's fees in a future trade-secrets suit. Worth flagging.

The "sign by Friday" deadline

The most common pressure tactic in severance negotiation is a sign-by date that falls inside the OWBPA window. The deadline is real in the sense that the employer can pull the offer. It is not real in the sense that any serious employer will hold the offer through the full statutory consideration window for an over-40 employee. Pulling the offer would itself look like retaliation in any subsequent suit.

The negotiation move: a written request for the full 21 days, or 45 if it's a group program, sent within 24 hours of receiving the agreement. Most HR teams accommodate. The ones that refuse are revealing something about how they expect the negotiation to go.

What to actually negotiate

The headline severance number is rarely where the value lives. Higher-leverage asks:

• Extended COBRA subsidy. Continuing the employer's healthcare contribution for 3-12 months. At ~$2,000/month for family coverage, this often exceeds 2-4 weeks of base pay.
• Accelerated equity vesting. Especially in startups, a 6-12 month vesting acceleration can be worth more than the entire cash severance.
• Neutral reference letter with agreed-on language. Costs the employer nothing. Saves you a year of explaining gaps.
• Garden leave / extended end date that pushes the termination date past a vesting cliff or quarterly bonus payout.
• Outplacement services the employer already has on contract.
• Relinquishment of any clawback of bonuses or expenses.

Most of these are line items the employer is willing to grant if asked. None will appear in the form unless you raise them.

Red flags that warrant a lawyer

A 30-minute consult with an employment lawyer typically runs $200-$500 and almost always pays for itself on a five-figure severance. Trigger points:

• Termination near a vesting cliff, bonus, or commission payout
• Layoff selection that disproportionately affects your protected class
• Pre-termination complaints about discrimination, harassment, FLSA, or safety
• Pending workers' comp claim
• Severance amount under industry norms (1-2 weeks per year of service is the floor, 2-4 weeks at senior levels)
• Non-compete or non-solicit broader than 12 months or all geography
• Catch-all release with no Excluded Claims carve-out

The shape underneath every severance is the same. The employer wants finality, the employee wants pay continuation, and the release language is where those two purposes collide. Reading it in the right order surfaces the negotiable from the load-bearing.
