How to handle redundancy in the United States
Reviewed by Mellow Editorial Team, HR & payroll content team
Redundancy in the United States — often called a "layoff" or "reduction in force" (RIF) — does not follow a single federal framework the way it does in many other countries. There is no statutory redundancy pay, no mandatory consultation period in most cases, and employment is generally at-will. What you do have are several specific legal obligations that, if missed, carry real consequences.
Understand the at-will baseline
Most US employment is at-will, meaning either party can end the relationship at any time, for any lawful reason, without notice. That gives employers more flexibility than most comparable countries, but it does not mean anything goes.
Layoffs can still trigger legal liability if:
- The selection process has a disparate impact on a protected class (age, race, sex, disability, etc.) under federal anti-discrimination law
- Employees have contractual protections — written employment agreements, offer letters with implied guarantees, or union collective bargaining agreements
- The timing or circumstances look like retaliation (for example, letting go of employees shortly after they filed an internal complaint)
Before you finalize a RIF list, have employment counsel review the selection criteria and run a basic adverse-impact analysis.
Check whether the WARN Act applies
The federal Worker Adjustment and Retraining Notification (WARN) Act requires 60 days' advance written notice when:
- You have 100 or more full-time employees, and
- You are laying off 50 or more employees at a single site within a 30-day period, or closing a facility entirely
Covered employers who fail to give proper notice can owe employees up to 60 days of back pay and benefits. There are narrow exceptions — unforeseeable business circumstances, natural disasters, and "faltering company" situations — but relying on them without legal guidance is risky.
Many states have their own "mini-WARN" laws with lower thresholds or longer notice requirements. California, New York, and New Jersey all have versions that can apply to smaller employers or require more notice than the federal floor. Check the rules in every state where affected employees are located.
Severance: voluntary, but consequential
There is no federal requirement to pay severance. If you offer it — and many employers do, both for goodwill and to reduce litigation risk — structure it carefully.
A few practical points:
- Severance in exchange for a release of claims is the most common arrangement. The release must be knowing and voluntary to be enforceable.
- If any employees are 40 or older, the Older Workers Benefit Protection Act (OWBPA) sets additional requirements: at least 21 days to consider the agreement (45 days in a group layoff), and a 7-day revocation period after signing. Missing these requirements invalidates the release entirely.
- In a group RIF, OWBPA also requires you to give affected employees a written list of job titles and ages of everyone selected and not selected for the layoff, within the same decisional unit. This is easy to overlook and regularly causes problems.
- Put severance terms in writing. Be consistent — inconsistent severance amounts across similar employees can raise discrimination flags.
Final pay and benefits obligations
Final pay deadlines are set by state law, not federal law, and vary considerably. Some states require payment on the last day of employment; others allow the next regular pay date. Get this right for every state involved.
COBRA requires employers with 20 or more employees to offer laid-off workers the option to continue their group health coverage at their own expense, for up to 18 months. You must send a COBRA election notice promptly after the qualifying event.
Accrued paid time off is another state-law question. California treats accrued vacation as earned wages that must be paid out on termination. Many other states do not, unless your own policy promises otherwise. Review your policy and the state rules before you process final pay.
Documentation and offboarding
Keep records of the business rationale for the RIF and the selection criteria used. If a discrimination claim arises later, you will need to show that decisions were based on legitimate, non-discriminatory factors — role elimination, performance metrics, skills requirements — and that those criteria were applied consistently.
On the administrative side, laid-off employees receive a Form W-2 reflecting all wages paid during the tax year, issued by January 31 of the following year. Severance is taxable income subject to regular withholding, including federal income tax, Social Security, and Medicare (FICA).

Revoke system access on the last day, retrieve company equipment, and confirm the employee's mailing address for final documents. A clean, respectful offboarding process reduces friction and protects both parties.
