Can I Still Sue After Signing a Severance Agreement?

Yes, you can sometimes sue after signing a severance agreement, but only in specific circumstances: when the release was obtained through fraud, coercion, or without real consideration; when the claim is one federal law says you cannot waive; or when the employer failed to meet the strict requirements that apply to waivers signed by workers 40 and older. Suing after signing a severance agreement is an uphill fight in every other situation, because a properly drafted release is a binding contract that gives up your right to sue for anything that happened during your employment.

When the Release Itself Can Be Attacked

A severance agreement is a contract, and contracts can be set aside when the circumstances around signing were improper. Courts look at whether the waiver was induced by fraud, duress, undue influence, or other improper employer conduct.¹

Fraud or misrepresentation happens when an employer lies to get you to sign. If HR told you the whole department was being cut, but in fact you were the only one let go and the real reason was your age, race, or gender, a court can void the release because your consent rested on false information.

Duress or coercion means the employer used improper threats that left you with no reasonable choice. A common example is conditioning your final paycheck on signing the release. That paycheck is legally owed regardless of any severance deal, so tying it to a waiver crosses from negotiation into coercion.

Lack of consideration is the most straightforward ground. A valid release requires the employer to give you something you were not already owed. If the agreement only repackages your final wages, accrued PTO, or vested retirement funds, you got nothing new in exchange for surrendering your legal rights, and the release fails as a contract.¹

Special Protection If You Were 40 or Older

If you were at least 40 when you signed, federal law gives you a structured checklist that often provides the strongest route to unwind a waiver. The Older Workers Benefit Protection Act (OWBPA), which amended the Age Discrimination in Employment Act, sets out specific requirements employers must satisfy for a waiver of age discrimination claims to count as “knowing and voluntary.” Miss even one, and the waiver of ADEA claims is unenforceable.²

A valid OWBPA waiver must:

Be written in plain language the average eligible employee can understand.
Specifically mention the ADEA by name; a generic release is not enough.
Cover only past claims, not claims arising after you sign.
Offer new consideration beyond anything you were already owed.
Advise you in writing to consult an attorney before signing.
Give you at least 21 days to consider the offer, or 45 days if it is part of a group layoff or exit incentive program.
Include a 7-day revocation window after signing during which you can change your mind.²

Group terminations carry an added disclosure requirement. When severance is offered as part of a group layoff or exit incentive program, the employer must disclose in writing the “decisional unit” from which selections were made, the eligibility factors, applicable time limits, and the job titles and ages of everyone eligible or selected as well as those in the same classifications who were not selected.¹ Broad age bands like “40–50” do not satisfy the requirement; individual ages are required.

If you were under 40, no federal statute mandates a minimum review period or specific waiver language. The general contract defenses still apply, but the OWBPA checklist is not there to help you. Some states impose additional waiver requirements regardless of age, so the ground available depends partly on where you worked.

Claims You Never Waived, No Matter What the Paper Says

Certain rights cannot be signed away as a matter of public policy. Even a technically valid release does not touch them.

EEOC Charges

You always keep the right to file a charge of discrimination with the Equal Employment Opportunity Commission. A severance agreement can waive your right to recover money personally from the charge, but it cannot bar you from filing one or cooperating with the agency’s investigation.¹

Whistleblower Reports

Federal law protects your right to report suspected legal violations to government agencies, and severance agreements cannot silence you. SEC Rule 21F-17 prohibits any person from taking action to impede someone from communicating directly with SEC staff about possible securities law violations, including through confidentiality agreements.³ The Sarbanes-Oxley Act states that the rights and remedies it provides for whistleblowers “may not be waived by any agreement, policy form, or condition of employment.”⁴ Similar protections cover reports to OSHA and other federal agencies.

Workers’ Compensation

A workers’ compensation claim for an on-the-job injury generally cannot be waived through a general release. Workers’ comp runs on a separate state statutory framework, and employers typically cannot offset severance against workers’ compensation benefits.

Vested Retirement Benefits

Benefits already vested under a retirement plan governed by ERISA, such as a 401(k) balance, cannot be forfeited through a severance agreement. ERISA’s nonforfeiture rules bar employers from conditioning vested pension benefits on signing a release.⁵

Unemployment Benefits

Your right to apply for unemployment insurance is set by state law, not by your severance agreement. An employer cannot stop you from filing a claim, though it can contest eligibility through the normal administrative process.

Future FMLA Rights

You cannot waive prospective rights under the Family and Medical Leave Act, and employers cannot induce you to do so. You can settle a claim based on a past FMLA violation, so a release of that specific past claim in exchange for severance is permissible.⁶

Unpaid Wages Under the FLSA

Claims for unpaid minimum wages or overtime under the Fair Labor Standards Act sit in a gray area. The traditional rule, followed by most federal appeals courts, is that FLSA claims cannot be privately settled without court approval or Department of Labor supervision. If you believe you are owed back wages, a boilerplate general release may not actually extinguish that claim.

Overbroad Non-Disparagement and Confidentiality Clauses

Many severance agreements bar you from saying anything negative about the company and require you to keep the agreement’s terms confidential. Since 2023, those clauses face a significant federal constraint. The National Labor Relations Board’s McLaren Macomb decision held that employers violate the National Labor Relations Act simply by offering a severance agreement with broad non-disparagement or confidentiality provisions that would chill employees from exercising their rights to discuss working conditions, organize, or support one another.⁷

This applies to private-sector employees whether or not they are in a union, because Section 7 of the NLRA protects the right of all covered employees to engage in collective activity about their terms and conditions of employment. A narrowly drafted non-disparagement clause may survive scrutiny, but sweeping “you agree never to say anything negative about the company” language is now legally suspect. If your agreement contains one, the clause itself may be unenforceable, and an employer that knowingly included an overbroad provision may also have undermined the voluntariness of the entire agreement.

Do You Have to Give the Severance Back First?

Many people ask whether they must return the severance payment before suing. The answer depends on the type of claim.

For ADEA claims, you do not. In Oubre v. Entergy Operations, Inc., the Supreme Court held that when a waiver fails to meet the OWBPA’s requirements, the employee can challenge the waiver without returning the severance payment.⁸ The EEOC codified this rule and confirmed that employers cannot penalize employees for challenging a waiver by making them agree in advance to pay damages or attorney’s fees for filing an age discrimination suit.⁹

For claims under Title VII, the Americans with Disabilities Act, or the Equal Pay Act, the law is less settled. Some courts require you to return the severance before proceeding. Others borrow the ADEA’s no-tender-back rule and let you keep the money while you challenge the release. Even courts that do not require tender back may reduce any eventual damages award by the amount of severance already paid.¹

Deadlines Are Still Running

An invalid severance agreement does not extend the life of your underlying claim. Federal employment discrimination claims have strict filing windows that run regardless of what you signed.

For most discrimination claims, you must file a charge with the EEOC within 180 calendar days of the discriminatory act. The deadline extends to 300 days if your state has its own anti-discrimination agency enforcing a similar law.¹⁰ For ongoing harassment, the clock starts from the last incident.

Before filing a private lawsuit under Title VII, the ADA, or the ADEA, you must first file a charge with the EEOC, wait for the agency to investigate or request a right-to-sue notice, and then file suit within 90 days of receiving that notice.¹¹ The 90-day window is a hard deadline. People who spend months debating whether to challenge a severance agreement sometimes lose track of these dates, and no amount of waiver invalidity helps if the statute of limitations has passed.

The Risk If the Release Holds Up

Suing after signing is not free even when you have a theory. If a court determines the release was valid, the employer can seek to recover the attorney’s fees and litigation costs it spent defending the case. For ADEA claims, the employer cannot build that penalty into the agreement itself as a deterrent, but the general risk remains.¹

The practical upshot: get an employment attorney’s assessment of whether your waiver has real vulnerabilities before committing to litigation. A strong argument that the employer botched an OWBPA requirement is very different from hoping a court will find duress in an ordinary time-pressured negotiation. A concrete non-waivable claim, a defective OWBPA waiver, a missing disclosure in a group layoff, an overbroad non-disparagement clause, or a serious misrepresentation is the kind of hook that turns a signed agreement back into a live case.
