When a large health care employer announces layoffs, the first question is almost always about the severance agreement sitting in your inbox. Federal law does not require any employer to offer severance. But two statutes give affected workers real procedural rights: the WARN Act controls how much advance notice the company must give before a mass layoff, and the Older Workers Benefit Protection Act (OWBPA) dictates how long you have to review, accept, or reject any waiver of age discrimination claims. Understanding these timelines is the difference between signing too fast and signing informed.

To see what these rules look like in practice, take Priya, a clinical data analyst who has worked at Optum for six years. Priya is 43, earns $105,000 a year, and just received a separation agreement with a 21-day review deadline. Her experience will anchor every worked example below.

What did Optum disclose about the 2026 layoffs?

Optum, a subsidiary of UnitedHealth Group and one of the largest health care services companies in the United States, reported a workforce reduction of about 524 roles on June 4, 2026. The company has not disclosed the percentage of its workforce affected by the cut. State WARN Act filings, where required, appear on dashboards maintained by individual state labor departments such as the New York Department of Labor[1] and the California Employment Development Department.[2]

Because Optum has not released a public SEC Item 2.05 filing specific to this event, the most detailed public record currently sits with state WARN notice databases and third-party layoff trackers. Affected employees should check their state's WARN dashboard to confirm whether a formal notice was filed for their specific worksite.

Does the federal WARN Act apply to a 524-person layoff?

The Worker Adjustment and Retraining Notification Act applies to employers with 100 or more full-time employees, or 100 or more employees (including part-time workers) who collectively work at least 4,000 hours per week, excluding overtime.[3] Optum far exceeds that threshold. A "mass layoff" under the statute occurs when an employer lays off at least 50 workers at a single site during any 30-day period, provided those 50 workers make up at least one-third of the site's workforce, or when 500 or more workers are laid off at a single site regardless of the one-third test.[3]

A 524-person reduction spread across multiple sites could trigger WARN at every site where 50 or more workers lose their jobs. The statute requires 60 calendar days of written notice to each affected employee, the state dislocated worker unit, and the local government.[3]

Employers sometimes offer "pay in lieu of notice," meaning they pay 60 days of salary and benefits instead of keeping workers on the payroll. The DOL's employer guide explains the mechanics of WARN compliance.[5] Receiving pay in lieu of notice does not waive WARN Act rights if the notice itself was deficient.

Which states have stricter mini-WARN laws that could affect Optum workers?

Several states impose layoff notice requirements that exceed the federal 60-day standard. Optum operates in dozens of states, so the applicable rule depends on where each affected worker is employed. Two of the most relevant state laws are California's WARN Act and New York's WARN Act. The table below compares federal and key state requirements.

Jurisdiction	Employer threshold	Layoff trigger	Notice period	Source
Federal	100+ full-time employees	50+ at one site (with one-third test) or 500+ at one site	60 days	29 U.S.C. § 2102 [3]
California	75+ employees	50+ in a 30-day period	60 days	CA EDD WARN page [2]
New York	50+ employees	25+ full-time employees	90 days	NY DOL WARN dashboard [1]

New York's threshold is notably lower: 50 employees rather than 100, and only 25 affected workers trigger the notice obligation. The notice period is 90 days, a full month longer than the federal floor.[1] California's threshold sits at 75 employees and does not include the federal one-third-of-workforce test for layoffs of fewer than 500.[2] Priya should check whether her worksite falls in a state with a mini-WARN overlay by visiting her state labor department's website.

How does OWBPA affect severance waivers for workers 40 and older?

If a severance agreement asks an employee to waive age discrimination claims under the Age Discrimination in Employment Act (ADEA), the waiver must satisfy the requirements of 29 U.S.C. § 626(f).[6] A waiver that does not meet these requirements is unenforceable, regardless of whether the employee signed it. The Supreme Court confirmed this rule in Oubre v. Entergy Operations, holding that a defective OWBPA waiver is voidable even after the employee accepts the severance payment.[7]

The core OWBPA requirements for a valid waiver include:

The agreement must be written in plain language an average eligible worker can understand.[6]
The employee must receive consideration (something of value) beyond what they are already owed.[6]
The agreement must advise the employee in writing to consult an attorney.[6]
For an individual termination, the employee gets at least 21 days to consider the agreement.[6]
For a group layoff or exit incentive program, the employee gets at least 45 days to consider.[6]
After signing, the employee has 7 days to revoke the agreement.[6]

The EEOC's guidance on OWBPA waivers details additional disclosure requirements for group layoffs, including decisional-unit data showing the ages of workers selected and not selected for layoff.[8]

Workers who feel pressured to sign before the 45-day window closes should know the deadline is a legal floor, not a suggestion. An employer cannot shorten it. For more detail on how severance agreements and OWBPA interact, see our guide on how to negotiate severance.

How does a severance payment interact with unemployment insurance?

This is one of the trickiest areas because unemployment insurance (UI) is administered state by state, and rules vary. Two states with large Optum workforces illustrate the range:

California: The California Employment Development Department treats a lump-sum severance payment as wages allocable to a specific period. If the payment is allocated to the period immediately following separation, UI benefits are deferred for that period.[9] A lump sum covering 12 weeks of pay, for example, would defer UI eligibility by 12 weeks.

New York: The New York Department of Labor treats dismissal pay (severance) as disqualifying during the period it covers if paid in installments, but a lump-sum payment does not reduce benefits if no continuing employment obligation exists.[10]

Regardless of state, file your UI claim the week you stop working. Even if benefits are temporarily deferred, the filing date establishes your claim and avoids losing weeks on the back end. Use our severance tax calculator to model the tax impact of lump-sum versus installment payments.

What terms can a departing Optum employee try to negotiate?

Low confidence

No federal statute requires an employer to offer severance at all. The package Optum provides is governed by company policy and, for some employees, by individual employment agreements. That said, several terms are commonly negotiable in health care layoffs:

Cash multiple. Many large employers offer one to two weeks of base salary per year of service. Optum has not disclosed its formula for this reduction.
COBRA subsidy. Employers sometimes pay COBRA premiums for a fixed period (often 3 to 6 months) rather than requiring the employee to cover the full cost.
Outplacement services. A commitment to job-search coaching or resume assistance.
Reference language. A written agreement on what the company will say to future employers.
Equity treatment. For employees with unvested RSUs or stock options, the separation agreement may address accelerated vesting or an extended exercise window.

Because these terms are not standardized by law, their availability depends on the employer's internal policies and the employee's individual negotiating position. Our severance negotiation guide walks through the mechanics step by step.

What should affected Optum employees do right now?

Priya's checklist applies to everyone inside a severance consideration window:

Read the full agreement before anything else. Do not sign on the day you receive it. OWBPA gives group-layoff participants 45 days.[6]
Check your state's WARN dashboard. Confirm whether Optum filed a WARN notice for your worksite. In New York, check the NY DOL WARN dashboard. In California, check the CA EDD WARN page.
File for unemployment insurance immediately. Even if your severance defers benefits, the filing date matters for claim processing.
Consult an employment attorney. OWBPA itself requires the employer to advise you to do this.[6] Many employment attorneys offer free initial consultations.
Run the numbers. Use the layoff calculator to estimate your total separation value, including severance, accrued PTO, WARN back pay (if applicable), and unemployment benefits.
Compare your offer to benchmarks. Read our analysis of recent tech and health care layoffs to see how other companies have structured similar packages.
Remember the 7-day revocation window. Even after you sign, you have 7 calendar days to change your mind on any ADEA waiver.[6]

Frequently asked questions

Does the WARN Act guarantee severance pay?

No. The WARN Act (29 U.S.C. § 2102) requires 60 days of advance written notice before a qualifying mass layoff, but it does not mandate severance pay.[3] If an employer fails to give the required 60 days of notice, 29 U.S.C. § 2104 requires the employer to pay back pay and benefits for each day of the notice shortfall, up to 60 days.[4] Workers sometimes confuse this back-pay remedy with severance, but the two are legally distinct. The WARN penalty compensates for inadequate notice, while severance is a contractual benefit the employer chooses to offer.

How long do Optum employees have to review a severance agreement?

Employees 40 and older who are part of a group layoff program receive at least 45 days to consider a severance agreement that includes an ADEA waiver, plus 7 days to revoke after signing.[6] Employees under 40 are not covered by OWBPA, and no federal statute sets a minimum review period for their waivers. The EEOC's guidance on OWBPA waivers provides a detailed checklist of required disclosures.[8]

Can I collect unemployment benefits while receiving severance?

The answer depends on your state. In California, lump-sum severance is allocated across weeks and defers UI benefits for the covered period.[9] In New York, a lump-sum dismissal payment generally does not reduce UI benefits as long as no continuing employment obligation exists.[10] File your claim immediately after your last day regardless of severance structure. Processing times can add weeks, and a delayed filing date can cost you benefit weeks on the back end.

What happens if I sign a severance waiver that violates OWBPA?

The Supreme Court ruled in Oubre v. Entergy Operations (1998) that an ADEA waiver failing to comply with OWBPA requirements is not valid, even if the employee accepted the severance payment and did not return it.[7] An employee who signed a defective waiver can still file an age discrimination claim. The employer cannot enforce the release. This rule applies regardless of whether the employee knew the waiver was defective at the time of signing. Workers who suspect a defective waiver should consult an employment attorney within the 45-day consideration window.

Should I negotiate my severance package or just accept it?

No federal law prevents employees from negotiating severance terms. Common items to discuss include the cash multiple (weeks of pay per year of service), COBRA premium subsidies, outplacement services, and reference language. Employees with unvested equity should review how the separation agreement treats stock options or RSUs. The severance negotiation guide on this site walks through the process. An employment attorney can also review whether the release language is broader than necessary, which creates room to negotiate better terms in exchange for the broader waiver.

What is the difference between WARN back pay and severance?

WARN back pay is a statutory penalty under 29 U.S.C. § 2104 that compensates employees when an employer fails to provide the required 60 days of advance notice before a mass layoff.[4] Severance pay is a voluntary employer benefit, typically offered in exchange for a release of legal claims. An employee can receive both: WARN back pay for any notice shortfall, plus whatever severance the employer offers under its separation agreement. The two do not offset each other unless the severance agreement explicitly says otherwise and the employee agrees to that term.
