Employment Contract Law in the United States

Most U.S. workers do not need a written employment contract. Employment is "at-will" by default—meaning either party can end the relationship anytime, for any legal reason, with or without written terms. Federal law only mandates specific clauses when waiving age discrimination claims, contracting with the federal government, or handling trade secrets.

Do I need a written employment contract?

Usually no for private sector work—most U.S. jobs are at-will without written contracts. You need a written contract with specific clauses only if you're waiving rights under the Age Discrimination in Employment Act (ADEA), working on a covered federal government contract, or signing a confidentiality agreement governing trade secrets.

What basic terms should every employment contract include?

If you have a written contract, it should cover these baseline terms: - Job title and description - Compensation (salary/hourly rate, pay frequency) - Start date and work location - Benefits eligibility - At-will vs. for-cause termination conditions - Probationary period (if applicable)

When is a written employment contract required?

Federal law requires written agreements with specific clauses in three situations:

1. ADEA Waivers: Any agreement waiving rights under the Age Discrimination in Employment Act must contain seven mandatory elements (29 U.S.C. § 626(f)):

For group termination programs, employers must provide written disclosures covering eligibility factors, time limits, and the job titles and ages of all individuals eligible or selected for the program and the ages of all individuals in the same job classification or organizational unit who are not eligible or selected (29 CFR 1625.22(f)).

The party asserting the validity of a waiver bears the burden of proving it was knowing and voluntary (29 U.S.C. § 626(f)(3)). No waiver may affect the EEOC's enforcement rights or interfere with an employee's right to file a charge or participate in EEOC proceedings (29 U.S.C. § 626(f)(4)).

2. Federal Government Contracts: Covered contracts must include specific Federal Acquisition Regulation clauses:

Non-construction prime contractors and subcontractors with 50+ employees and a contract or subcontract of $50,000+ must maintain a written affirmative action program (FAR Subpart 22.8).

Government contractors must include a clause informing employees of NLRA rights, which may be incorporated by citation; physical posting must be conspicuous where employees will likely see it, with multilingual notices for non-English workforces and electronic posting only for contractors who customarily post electronically (29 CFR 471.2).

3. Trade Secret Agreements: Any confidentiality or trade secret agreement entered into or updated after May 11, 2016 must include notice of immunity under 18 U.S.C. § 1833(b) for disclosing trade secrets to report violations or in sealed filings, or may provide a cross-reference to a compliant policy document (18 U.S.C. § 1833(b)(3)).

Sexual Assault and Harassment Disputes

• Arbitration and joint-action waivers: No predispute arbitration agreement or joint-action waiver is valid or enforceable with respect to a case alleging conduct constituting a sexual assault or sexual harassment dispute, at the election of the person alleging such conduct or their representative (9 U.S.C. § 402). A court, not an arbitrator, determines the applicability of this chapter and the validity of any agreement or waiver to which it applies (9 U.S.C. § 402(b)).
• Nondisclosure and nondisparagement clauses: These are judicially unenforceable for sexual assault or sexual harassment disputes when the conduct is alleged to have violated Federal, Tribal, or State law, for claims filed on or after December 7, 2022 (42 U.S.C. Chapter 164).

Noncompete Agreements

There is no operative federal ban on noncompete clauses. The FTC's Noncompete Rule was enjoined August 20, 2024, and the FTC dismissed its appeal September 5, 2025; as of the latest source information, no operative federal ban exists. Enforceability remains governed entirely by state law.

Involuntary Servitude and Peonage

Any contract term compelling labor through force, legal action, or threats is unenforceable under the Thirteenth Amendment. Contracts attempting to create debt bondage or peonage are void under 42 U.S.C. § 1994.

Non-Waivable Rights

Employees cannot waive these rights in any agreement:

When is an employment contract legally binding?

Consideration

A waiver must be supported by consideration in addition to anything of value to which the individual is already entitled (29 CFR 1625.22(d)). For ADEA waivers, this means consideration in addition to anything of value to which the individual is already entitled (29 CFR 1625.22(d)).

Employee vs. Independent Contractor Classification

Federal law uses different tests:

FLSA (Wage and Hour): The "economic reality" test examines six non-exhaustive factors: (1) opportunity for profit or loss depending on managerial skill; (2) investments by the worker and potential employer (compared on relative basis); (3) degree of permanence of the work relationship; (4) nature and degree of control; (5) extent to which work is integral to the employer's business; and (6) skill and initiative (DOL Final Rule, effective March 11, 2024).

ERISA and ADEA: The common-law agency test applies, focusing on the hiring party's right to control how work is performed.

Copyright Act: "Work made for hire" requires either an employment relationship under common-law agency principles or a specially commissioned work in nine enumerated categories with a written agreement (17 U.S.C. § 101).

Worker classification depends on the specific test applied: FLSA uses economic reality; ERISA/ADEA use common-law agency; Copyright Act uses common-law agency principles. Ask Sawyer researches federal and state law to answer questions about your facts.

Arbitration Clauses

Under the Federal Arbitration Act, arbitration agreements are generally enforceable (9 U.S.C. § 2), but with key exceptions: - Transportation workers: The FAA does not apply to seamen, railroad employees, or workers engaged in foreign or interstate commerce (9 U.S.C. § 1). The Supreme Court clarified in Bissonnette v. LePage Bakeries Park St., LLC, 601 U.S. 246 (U.S. 2024) that the test is "what the worker does," not whether the employer is in the transportation industry. - Sexual assault/harassment: As noted above, predispute arbitration agreements are voidable.

Forum Selection and Choice-of-Law Clauses

Forum selection clauses are prima facie valid unless enforcement would be contrary to a strong public policy of the forum or the clause is unreasonable—meaning it was the product of fraud, undue influence, or overweening bargaining power, or would deprive the party of their day in court (M/S Bremen v. Zapata Off-Shore Co., 407 U.S. 1 (1972)). Courts should transfer cases to the agreed forum absent extraordinary circumstances (Atlantic Marine Construction Co. v. U.S. District Court, 571 U.S. 49 (2013)).

Choice-of-law clauses are generally honored if the chosen state has a substantial relationship to the parties or the transaction and the application of that state's law is not contrary to a fundamental policy of a state with a materially greater interest.

What mistakes make employment contracts unenforceable?

How does state law differ from federal rules?

States may impose additional requirements, such as longer consideration periods or specific formatting for state age-discrimination waivers, and may apply different classification tests (source bundle notes: no single national standard exists; state law controls).

Because enforcement of specific clauses depends on your jurisdiction, industry, and job duties, Ask Sawyer researches both federal and state law to answer questions about your situation.
