The OWBPA Severance Review Window: 21 or 45 Days Explained for Workers 40+

This article explains the Older Workers Benefit Protection Act (OWBPA) severance review window, how to know which timeline applies to you, and what to do during that window.

What the OWBPA Is

The Older Workers Benefit Protection Act of 1990 amended the Age Discrimination in Employment Act of 1967. The amendment specifically addressed the conditions under which workers aged 40 and older can knowingly and voluntarily waive age discrimination claims, typically in exchange for severance benefits.

In plain language: when your employer asks you to sign a severance agreement that includes a release of claims, that release cannot waive age discrimination claims unless specific federal requirements are met.

The OWBPA imposes strict requirements on employers. Failure to meet any one of these requirements voids the age discrimination waiver.

The Two Different Time Windows: 21 Days vs. 45 Days

The length of your review window depends on whether you were laid off individually or as part of a group.

21-Day Window: Individual Layoff

If you are the only one being laid off in your situation, or your termination is unrelated to a group action, you have 21 calendar days to review the severance agreement before signing.

This applies when:

• You are being terminated for a reason unrelated to others (performance, restructuring of a single role, individual position elimination)
• The agreement is presented to you alone

45-Day Window: Group Layoff

If you were laid off as part of a "group termination program," you have 45 calendar days to review the severance agreement before signing.

This applies when:

• Two or more employees are being terminated as part of the same employer action
• The terminations are part of a reduction in force, reorganization, or layoff
• The agreement is presented as part of an "exit incentive program" or similar group action

The 45-day window also requires the employer to provide additional information not required for individual layoffs (described below).

How to Tell Which Window Applies to You

Look at the severance agreement itself. The agreement must explicitly state which window applies. If it says "21 days," it is being treated as an individual layoff. If it says "45 days," it is a group layoff.

If the agreement says 21 days but you know other people were laid off in the same wave, the 21-day window may be insufficient. You should consult an employment attorney before signing.

Other signs of a group layoff:

• Multiple coworkers received severance offers on the same day
• The company announced a reduction in force, layoff, or restructuring
• Your manager or HR mentioned a broader workforce action
• News reports cover layoffs at your company

If any of these apply, you may be entitled to the 45-day window.

The 7-Day Revocation Period

OWBPA also requires a 7-day revocation period after you sign. The clock starts the day you sign. For 7 calendar days afterward, you can revoke your acceptance and the agreement becomes void.

This means even after you sign, you have one more week to change your mind.

Practical implications:

• The agreement is not legally effective until day 8 after you sign
• Severance payments typically do not start until after the revocation period ends
• Revocation must be in writing per the agreement's specified procedure (usually email or certified mail to a specific HR contact)

What the Group Layoff Disclosure Must Include

If you are in a 45-day window group layoff, your employer must give you specific information about who else is being laid off. This is one of the strictest OWBPA requirements.

The disclosure must include:

• The "decisional unit" (the group from which the employer chose who to lay off)
• The eligibility factors for the program
• Time limits applicable to the program
• The job titles and ages of all individuals selected for the program
• The job titles and ages of all individuals in the same decisional unit who were not selected

This last point is critical. By disclosing the ages of who was kept and who was let go, the law gives you data to evaluate whether you have an age discrimination claim.

What to Do During the Review Window

The review window is not just a waiting period. It is time to do five specific things.

1. Read the entire agreement

Read every sentence. Pay particular attention to:

• The release of claims (what claims you are waiving)
• Non-disparagement clauses (what you can and cannot say after leaving)
• Non-compete and non-solicit clauses (what work you cannot take)
• Cooperation clauses (what assistance the company can demand later)
• Confidentiality provisions (what information you must keep private)
• Return of property requirements

2. Calculate the actual severance value

Severance is more than the cash payment. Total compensation includes:

• Lump-sum or continued-salary payment amount
• COBRA subsidy (if employer is paying part of your premium)
• Accelerated equity vesting (if any)
• Outplacement services value
• Bonus accrual for the year
• Unused vacation and sick time payout
• Any retention bonuses being paid out

Add it all up. The headline number on page 1 may understate the total package.

3. Compare to peers

If you have access to information about what others at your level received, this is the time to use it. Anonymized peer benchmarks (such as those Layoff HQ provides as part of paid plans) help you understand whether your offer is at, above, or below market.

4. Consider negotiating

Most laid-off workers do not negotiate severance, assuming the offer is final. It usually is not. Reasonable areas to negotiate:

• Larger lump-sum payment, especially for senior roles
• Extended COBRA subsidy (often 3 to 6 months instead of 1 to 2)
• Accelerated vesting on some or all unvested equity
• Removal or narrowing of non-compete language
• Extended exercise window for vested options (some companies extend from 90 days to 1 year or longer)
• Mutual non-disparagement (the company also agrees not to disparage you)
• Letter of recommendation or agreed reference language

5. Decide whether to consult an attorney

The OWBPA explicitly recommends consulting an attorney before signing. The agreement itself usually contains language advising you of this right.

Cost of severance review by an employment attorney: typically $200 to $400 for a written analysis, $400 to $800 for a phone consultation plus written analysis. If your severance is worth more than $30,000, the cost of an attorney is almost always worth it.

Common Mistakes Workers 40+ Make

Mistake 1: Signing on the day they receive the offer. Federal law explicitly gives you time. Use it.

Mistake 2: Not realizing the 7-day revocation period exists. If you sign and immediately regret it, you have 7 days to back out.

Mistake 3: Treating the offer as final. Companies have flexibility, especially for senior roles. The "standard package" is usually the opening offer, not the only offer.

Mistake 4: Ignoring the group layoff disclosure data. The list of ages of laid-off and kept employees is given to you for a reason. Read it. Look for patterns.

Mistake 5: Waiving age discrimination claims without understanding what you are waiving. The release language matters. If a pattern of age discrimination is visible in the disclosure, that release has substantial value.

What If You Already Signed?

If you signed within the past 7 days, you can still revoke. The agreement specifies how. Send the revocation in writing per the procedure stated.

If you signed more than 7 days ago, the OWBPA waiver is generally enforceable, but only if all the OWBPA requirements were met. If any single requirement was not met, the age discrimination waiver is void and you may still bring an age discrimination claim within the standard 180-day or 300-day filing window.

The most common OWBPA failures:

• Failure to give the full review window (21 or 45 days)
• Failure to provide the group disclosure for group layoffs
• Failure to include the 7-day revocation language
• Pressure or coercion to sign quickly
• Failure to advise consultation with an attorney

If you suspect any of these, consult an employment attorney to evaluate whether the waiver is enforceable.

Frequently Asked Questions

Does OWBPA apply if I am 39?

No. OWBPA protections apply only to workers aged 40 and older at the time of the layoff. Younger workers can still be subject to standard severance agreement law but do not get the OWBPA review windows.

Can my employer reduce the review window?

No. The 21-day and 45-day windows are minimums set by federal law. An employer can offer more time but cannot offer less.

Does signing waive my unemployment benefits?

No. Severance and unemployment are separate. Some states reduce or delay unemployment if you receive severance, but signing the agreement does not waive your right to file.

Can the company rescind the offer if I take the full window?

Generally no, but read the agreement. Most agreements specify the offer is open for the full statutory window. If your agreement says otherwise, ask in writing for clarification.

Tracking the Window

Layoff HQ tracks your specific OWBPA window based on your last day worked, age at layoff, and group layoff status. We send reminders 14 days, 7 days, and 1 day before the window closes. We also identify if your situation may qualify for the longer 45-day window even if the agreement says 21 days.
