OWBPA: The 21-Day Rule for Severance Agreements
The Older Workers Benefit Protection Act gives employees 40+ at least 21 days to consider severance offers and 7 days to revoke after signing. Here is how the rule works, what makes a waiver valid, and what to do with the time.
If you are 40 or older and your employer asks you to sign a severance agreement, the law gives you time and the law is specific about how much. The Older Workers Benefit Protection Act (OWBPA), enacted in 1990 as an amendment to the Age Discrimination in Employment Act (ADEA), sets out what an employer must do to obtain a valid waiver of age-discrimination claims. The headline rules are 21 days to consider, 7 days to revoke, and 45 days for group layoffs. Understanding how each one operates changes what you do during the offer window.
What OWBPA covers and who it applies to
OWBPA applies whenever an employer conditions severance, enhanced severance, or any other benefit on the employee waiving claims under the ADEA. The ADEA itself protects employees aged 40 and over from age-based discrimination in hiring, firing, promotion, compensation, and benefits. If you are 40 or over and your severance agreement contains a release of claims, that release almost certainly includes ADEA claims, which is what triggers OWBPA's procedural requirements (29 U.S.C. § 626(f), Cornell Law, verified April 2026).
OWBPA does not require your employer to give you severance. It governs how a waiver is obtained when severance is offered. An employer can decline to offer severance at all and OWBPA has no role. Once the offer is on the table with a release of ADEA claims attached, the procedural floor kicks in.
The 21-day consideration rule
For an individual separation, the employer must give you at least 21 days to consider the agreement before you sign. This is a floor. Your employer can give you more time and frequently does. The 21 days starts when you receive the agreement in final, written form. If your employer materially changes the terms during the 21-day window, the count restarts under EEOC interpretation, although a minor edit (a typo, a name correction) does not (EEOC OWBPA guidance, verified April 2026).
You can sign earlier than 21 days if you choose to. But the agreement still has to give you the option of taking the full 21 days. An agreement that requires you to sign within, say, 7 days is invalid as to the ADEA waiver, even if you would have signed quickly anyway. The Supreme Court made this point clear in Oubre v. Entergy Operations, Inc., 522 U.S. 422 (1998): a defective OWBPA waiver does not bar an ADEA claim, and the employee does not have to return the severance to bring the claim.
The 7-day revocation rule
After you sign, you have at least 7 days to revoke. Revocation must be in writing and delivered to whoever the agreement designates. Your employer cannot pay you the severance until the 7-day revocation period expires. That is OWBPA's structural protection: even if you signed under emotional pressure, you have a week to think it over and pull back without losing your job (you have already lost your job; you would lose only the severance) (29 U.S.C. § 626(f)(1)(G), verified April 2026).
The 7-day window is also a floor. Your employer can give you longer. State law sometimes layers on additional revocation rights. California and Minnesota in particular impose state-specific revocation periods that overlap with OWBPA but are not identical.
Group layoffs and the 45-day rule
If your separation is part of a "group termination" or "exit incentive program" affecting two or more employees, the consideration period extends from 21 days to 45 days. The 7-day revocation period stays at 7. The 45-day period exists because group layoffs are statistically more likely to disparately affect older workers, so the law gives those workers more time to consider the implications (29 U.S.C. § 626(f)(1)(F)(ii), verified April 2026).
In a group layoff, OWBPA also requires the employer to disclose the eligible job titles and ages of all individuals selected, and the eligible job titles and ages of all individuals not selected, in the same decisional unit. This disclosure is what makes age-discrimination claims actionable in group layoffs: without the data, employees can't determine whether older workers were selected at higher rates than would be expected by chance.
What makes an OWBPA waiver valid
OWBPA enumerates seven requirements. A waiver missing any of them is not "knowing and voluntary" and does not bar the employee from bringing an ADEA claim.
| # | Requirement | Source |
|---|---|---|
| 1 | Written in plain English the employee can understand | 29 U.S.C. § 626(f)(1)(A) |
| 2 | Specifically references rights under the ADEA | 29 U.S.C. § 626(f)(1)(B) |
| 3 | Does not waive rights or claims that arise after the date of signing | 29 U.S.C. § 626(f)(1)(C) |
| 4 | Exchanged for consideration above and beyond what the employee is already entitled to | 29 U.S.C. § 626(f)(1)(D) |
| 5 | Advises the employee in writing to consult an attorney before signing | 29 U.S.C. § 626(f)(1)(E) |
| 6 | Provides at least 21 (individual) or 45 (group) days to consider | 29 U.S.C. § 626(f)(1)(F) |
| 7 | Provides at least 7 days after signing to revoke | 29 U.S.C. § 626(f)(1)(G) |
If any of these are missing or defective, the waiver is unenforceable as to ADEA claims even if the employee signed and accepted the severance (29 U.S.C. § 626(f), Cornell Law, verified April 2026).
What to do if your employer's agreement is non-compliant
A waiver that violates OWBPA does not bar an ADEA claim. The Supreme Court in Oubre held that the employee does not have to "tender back" the severance before suing. You can keep the severance and still pursue the ADEA claim. This rule has practical consequences: if your agreement gives you only 14 days to consider when 21 are required, or omits the written advisement to consult counsel, you have a defective waiver and you retain your ADEA rights regardless of whether you sign.
Bringing an ADEA claim usually starts with a charge filed at the EEOC within 180 days (or 300 days in deferral states) of the alleged discrimination. The EEOC investigates, attempts conciliation, and either pursues the claim itself or issues a right-to-sue letter that lets the employee file in federal court (EEOC charge process, verified April 2026).
How to use the 21-day window
The 21 days is leverage. Most employees sign on day 3 or 4 because the offer feels final and they want to move forward. The employer's experience says otherwise: about half of all severance agreements receive at least one counterproposal during the consideration period, and the consideration period itself is the obvious moment to send one.
What to ask for during the 21 days:
- Cleaner non-disparagement language that is mutual rather than one-sided
- A neutral reference letter or agreed-upon talking points for prospective employers
- Extension of healthcare coverage past the standard COBRA window
- Acceleration of any unvested equity that would have vested in the next 6 to 12 months
- A longer post-termination exercise window for vested stock options
- Removal of any non-compete or non-solicit language that overreaches
The layoff calculator grades severance offers against industry benchmarks and surfaces the specific clauses to negotiate. The methodology page documents the data sources behind those benchmarks.

FAQ
How does OWBPA interact with state law?
OWBPA is the federal floor. State laws can layer on additional consideration periods, additional revocation periods, or additional waiver requirements. California's Business and Professions Code § 16600 voids most non-compete clauses regardless of OWBPA, and California Code of Civil Procedure § 1542 requires specific language for general releases. Minnesota Statute § 181.932 provides additional revocation rights. Your state's specific overlay shows up in the calculator's state-by-state data for California or /ny for New York. The federal protections apply on top of any state protections, never instead of them.
What if I have already signed and the 7 days have not passed?
Send written notice of revocation to the contact named in the agreement, by the method the agreement specifies (email, certified mail, hand delivery to HR, etc.). Send it before the 7-day window closes. Keep proof of delivery. Once revoked, the agreement is void and you do not receive the severance, but you also have not waived any claims.
Does OWBPA apply if I am under 40?
No. OWBPA's procedural requirements are tied to ADEA waivers, and the ADEA only protects employees 40 and over. If you are under 40, your employer is not required to give you 21 days, 7 days to revoke, or any of the OWBPA disclosures. State law may still impose its own consideration-period or revocation requirements; check your state's overlay before signing.
What is a "decisional unit" for the group disclosure?
The decisional unit is the broader group from which the employer selected those terminated. It might be a department, a job classification, a geographic location, or the entire company, depending on how the layoff was structured. The employer's selection of decisional unit affects whether disparate-impact age-discrimination claims are viable, which is why OWBPA requires the disclosure in the first place. The EEOC's interpretation runs in 29 CFR § 1625.22, verified April 2026.
Can my employer revoke the offer during the 21-day period?
Generally yes, but not as retaliation for protected activity (filing an EEOC charge, complaining about discrimination, etc.). Most employers will not revoke once the offer is on the table because doing so creates its own legal exposure, but the consideration period is not a binding offer in the contract sense. If the offer is revoked, see an employment attorney before doing anything else.
