How Wrongful Termination Claims Work Under U.S. Employment Law

At-Will Employment Is the Rule—But the Exceptions Are Everywhere

The United States is one of the only developed nations where private-sector employees can legally be fired at any time, for any reason, or for no reason at all—without notice and without severance. This "at-will" employment doctrine, established in nineteenth-century common law, remains the default rule in 49 states. (Montana is the sole exception, requiring good cause for termination after a probationary period under the Montana Wrongful Discharge From Employment Act.) Yet the number of successful wrongful termination lawsuits filed each year—along with hundreds of thousands of EEOC charges—demonstrates that the exceptions to at-will employment are substantial, consequential, and frequently litigated.

Understanding wrongful termination requires understanding when at-will employment ends and statutory or common law protections begin.

Three Categories of Wrongful Termination

Wrongful termination claims fall into three broad categories, each with distinct legal foundations.

Federal statutory protections are the most powerful. Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e-2, prohibits termination based on race, color, religion, sex, or national origin. The Age Discrimination in Employment Act (ADEA), 29 U.S.C. § 623, protects workers 40 and older. The Americans with Disabilities Act (ADA), 42 U.S.C. § 12112, prohibits termination for disability where a reasonable accommodation would allow the employee to perform essential job functions. The Pregnancy Discrimination Act, 42 U.S.C. § 2000e(k), and the Pregnant Workers Fairness Act of 2022 extend protections to pregnancy, childbirth, and related conditions.

Retaliation Claims: The Most Commonly Filed EEOC Charge

Retaliation is the single most frequently charged violation in EEOC filings—comprising over 55% of all charges filed in recent years. Federal law prohibits employers from firing, demoting, or taking adverse action against employees who engage in protected activity.

• Filing or participating in an EEOC complaint or discrimination lawsuit is protected under Title VII's anti-retaliation provision, 42 U.S.C. § 2000e-3.
• Opposing discriminatory practices—such as reporting harassment to HR—is protected even if the underlying claim is ultimately unsuccessful, provided the employee had a good faith belief the conduct was unlawful. Crawford v. Metropolitan Government of Nashville, 555 U.S. 271 (2009).
• Whistleblower protections under the Sarbanes-Oxley Act, 18 U.S.C. § 1514A, shield employees of publicly traded companies who report securities fraud.
• The Dodd-Frank Wall Street Reform and Consumer Protection Act, 15 U.S.C. § 78u-6, extends protections to employees who report securities violations to the SEC—with potential monetary awards.

The EEOC Process and Exhaustion Requirement

Before filing a federal lawsuit for discrimination or retaliation under Title VII, the ADA, or the ADEA, employees must exhaust administrative remedies by filing a charge with the Equal Employment Opportunity Commission (EEOC) within 180 days (or 300 days in states with a fair employment practice agency) of the discriminatory act.

• The EEOC investigates the charge and may attempt mediation or conciliation.
• If the EEOC dismisses the charge or does not resolve it within 180 days, it issues a Right to Sue letter, which gives the employee 90 days to file in federal court.
• Under § 1981 of the Civil Rights Act of 1866, 42 U.S.C. § 1981, race discrimination claims can be filed directly in federal court without EEOC exhaustion and with a four-year statute of limitations.

Damages Available in Wrongful Termination Cases

The damages available depend on the legal theory underlying the claim.

State law claims often permit uncapped damages. Some state statutes—such as California's Fair Employment and Housing Act (FEHA) and New York State Human Rights Law—provide broader protections and more generous remedies than their federal counterparts, including uncapped compensatory and punitive damages.

Wrongful termination law rewards those who document everything. Emails, performance reviews, HR complaints, and witness names become the evidentiary backbone of every successful claim.
