Is Severance Pay Required in the US? What Federal Law Says

CheckMySeverance Editorial Team·Reviewed by Founders LLP·April 7, 2026·5 min read

Is severance pay required in the US? No, federal law does not mandate severance pay for private sector employees in the United States. Many employees mistakenly believe employers must offer it upon termination, but this requirement only arises under specific state laws or company policies. For US workers facing a layoff, understanding these rules can reveal opportunities to negotiate far beyond zero.

Key Takeaways

  • US federal law imposes no general requirement for severance pay upon termination without cause.
  • In California, WARN Act violations can trigger 60 days' pay for mass layoffs affecting 75+ employees.
  • Massachusetts mandates 1 week per year of service, up to 52 weeks, for companies with 100+ employees.
  • Common law or contracts in the US rarely exceed 2-6 months for senior roles, far below Canada's up to 24 months.

No Federal Mandate: The Foundational US Rule on Severance

US private employers face no obligation to pay severance under the Fair Labor Standards Act (FLSA, 29 U.S.C. § 201 et seq.) or any federal statute for individual terminations. The Worker Adjustment and Retraining Notification (WARN) Act (29 U.S.C. § 2101 et seq.) requires 60 days' notice or pay only for mass layoffs or plant closings affecting 50+ full-time employees at a single site, or 500+ employees total. Smaller layoffs trigger no federal payout.

State laws fill some gaps but remain limited. For example, 18 states have mini-WARN acts with varying thresholds, such as New York's requirement for 25+ employees or one-third of the workforce. These apply strictly to group terminations, not individual firings. Employers often provide severance voluntarily to secure releases from lawsuits, but employees forfeit negotiation leverage by signing without review.

Federal exceptions exist for government contractors under the Service Contract Act (41 U.S.C. § 6701 et seq.), which mandates one week's pay per year of service in some cases. Unionized workers follow collective bargaining agreements, which may specify severance formulas. Still, 90% of US private employees receive nothing statutorily mandated upon without-cause dismissal.

The Critical Nuance: Releases and State-Specific Entitlements Employees Overlook

Most US employees miss that severance, when offered, requires signing a release waiving all claims, including under the Age Discrimination in Employment Act (ADEA, 29 U.S.C. § 621 et seq.). Courts enforce these strictly, as in Oubre v. Entergy Operations, Inc., 522 U.S. 422 (1998), where the Supreme Court invalidated a defective release but upheld the principle that valid waivers bar future lawsuits. Employees who sign lowball offers lose rights to sue for discrimination or retaliation under Title VII of the Civil Rights Act of 1964 (42 U.S.C. § 2000e et seq.).

State laws create hidden entitlements some ignore. In Massachusetts, under Mass. Gen. Laws ch. 149, § 148, employers with 100+ employees must pay one week per year of service, capped at 52 weeks, upon plant closing. A real-world example: A 52-year-old marketing director with 9 years of service in Massachusetts earning $120,000/year ($2,307.69/week) qualifies for 9 weeks, or $20,769.21. If the employer offers only 4 weeks ($9,230.76) conditioned on a release, the employee could negotiate to the full amount plus benefits continuance, potentially adding $5,000 in health premiums.

Another overlooked case is Cassidy v. Mineta, 835 F. Supp. 2d 7 (D.D.C. 2009), affirming no federal severance duty absent contract but allowing equitable claims for promised packages. Workers in at-will states like Texas or Florida get nothing statutorily, pushing reliance on negotiation. Compare this to Canada: Ontario's Employment Standards Act, 2000 (SO 2000, c 41), S. 64 mandates up to 26 weeks' severance for firms with $2.5M+ global payroll after 5 years' service.

This table highlights US sparsity. Federal WARN covers just 4% of layoffs. California demands 60 days for qualifying events via Cal. Lab. Code § 1400 et seq. Massachusetts ties payouts to tenure explicitly.

Common Mistakes US Employees Make with Severance Offers

Employees sign releases on day one without calculating full value, forfeiting discrimination claims worth six figures.

They ignore state mini-WARN applicability, accepting zero pay in group layoffs when 60 days' wages apply.

Workers overlook bonus and equity inclusion, settling for base salary only despite OWBPA (29 U.S.C. § 626(f)) requiring 21-45 day review periods for age 40+.

Many fail to demand continued benefits, losing COBRA subsidies that add 20-30% to package value.

Employees accept installment plans without guarantees, risking non-payment if the firm declares bankruptcy mid-term.
