Definition
A person who works for another — an individual or entity — under terms that give the hiring party the right to control not only the result of the work but the manner and means by which the work is performed. This control test is the defining characteristic that separates an employee from an independent contractor, who retains discretion over how the work is done.
The term carries weight across multiple legal frameworks simultaneously. Under employment law, classification as an employee triggers a web of statutory protections — wage and hour requirements, anti-discrimination statutes, workers' compensation coverage, and collective bargaining rights — that do not attach to independent contractors. Under tax law, the employee classification determines payroll tax withholding obligations. Under tort law, it activates respondeat superior liability, making the employer answerable for the employee's wrongful acts committed within the scope of employment.
Common Language
Modern common usage (Wiktionary): A person who provides labor to a company or another person.
Historical common usage (Webster's 1913): One employed by another.
The common definitions are not wrong, but they are fatally underinclusive for legal purposes. In ordinary speech, "employee" simply describes anyone working for pay. In law, the word does substantial classificatory work: not everyone providing labor qualifies. A freelancer, a gig worker, a leased worker through a staffing agency, or a partner in a firm may all be providing labor to a company, yet none may be an "employee" in the legal sense. The legal definition is a determination, not merely a description — and that determination has concrete, high-stakes consequences for both parties.
Common Confusion
EMPLOYEE vs. INDEPENDENT CONTRACTOR: The most consequential classification dispute in employment law. Both provide labor; the difference lies in the degree of control exercised by the hiring party. Numerous multi-factor tests exist across federal and state law — the IRS common law test, the Fair Labor Standards Act's economic reality test, and various state-law ABC tests — and they do not always reach the same result. A worker may be an employee under one framework and an independent contractor under another simultaneously.
EMPLOYEE vs. AGENT: All employees act as agents of their employer within the scope of employment, but not all agents are employees. An independent contractor can be an agent without being an employee. The distinction matters for respondeat superior analysis and scope-of-authority questions.
Core Elements
Because "employee" is a legal determination rather than a self-evident fact, courts and agencies apply structured tests. The dominant factors across most frameworks:
— Behavioral control: Does the hiring party control how the work is done, not just the outcome?
— Financial control: Who sets the pay rate, bears the risk of loss, and provides tools or equipment?
— Type of relationship: Is there a written contract? Are employee-type benefits provided? Is the relationship permanent or project-specific?
— Economic dependence: Is the worker economically dependent on this hiring party, or operating an independent business?
No single factor is typically dispositive. The weight given to each varies by jurisdiction and by the specific legal framework being applied.
Recognized Forms
/SUBTYPES
At-will employee: An employee whose relationship may be terminated by either party at any time, for any reason not prohibited by law. The default rule in most U.S. jurisdictions.
Leased or temporary employee: Placed by a staffing agency; questions of joint employer status arise regarding which entity bears statutory obligations.
Statutory employee: A category defined by specific federal or state statutes (notably the Internal Revenue Code) that extends employee classification — for tax purposes — to certain workers who might otherwise qualify as independent contractors under common law tests.
Probationary employee: A worker in an introductory period, often with reduced access to certain benefits or protections; the term's legal significance depends heavily on the applicable contract or policy.
Why It Matters in Research
Classification disputes are among the most litigated questions in employment law, and the applicable test shifts depending on which statute or legal doctrine is at issue. A researcher must always ask: employee for what purpose, under what framework? The FLSA uses an economic reality test; the NLRA has its own analysis; the IRS applies common law behavioral and financial control factors; California's AB5 codified an ABC test that is far more worker-protective than federal standards. These frameworks exist in parallel and can diverge sharply for the same worker.
Historical sources — including the Black's Law Dictionary entries below — are of limited utility here. The modern employee-classification problem is largely a product of the regulatory state: the FLSA (1938), the NLRA (1935), the IRC, ERISA, and anti-discrimination statutes created the legal stakes that make the definition consequential. Pre-New Deal dictionary definitions predate most of this architecture and reflect a world where the employee/contractor distinction carried far less legal freight.
Researchers working in historical sources should also note the Black's suggestion that "employee" connoted a person in permanent or at least stable employment. Gig economy and platform-worker disputes — now a primary battleground — involve precisely the opposite: workers in fluid, project-based arrangements. Modern cases have extensively reexamined what "permanence" and "dependence" mean in this context.
The encyclopedia entries on employee handbooks and social media speech are useful starting points for the contractual and expressive-rights dimensions of the employment relationship, both of which presuppose that classification as an employee has already been established.
Historical Dictionary Support
Both Black's editions draw on the same source passage, noting that "employee" arrived from the French and was not originally a pure legal term of art. The historical dictionaries observe that in French practice the word tended toward official or governmental employment, while American usage broadened it to include private employment generally — though with a residual connotation of permanence or stable engagement.
This etymology-forward treatment reflects the word's relative novelty in American legal vocabulary at the time these editions were compiled. What the historical dictionaries do not — and could not — provide is any engagement with the control test, the economic reality test, or the multi-factor classification frameworks that now dominate the field. The 2nd Edition entry compounds the confusion by opening with a reference to the emphyteusis lessee, which appears to be a printer's error or mis-collation in the source; it is not a recognized secondary meaning of "employee."
The historical entries are useful primarily as evidence that the term entered American legal writing without a settled technical definition, which helps explain why courts and legislatures have spent a century constructing the classification tests that fill that void.
Jurisdictional Note
Variation is significant and researchers cannot assume federal standards transfer to state law. California applies an ABC test under AB5 that presumes worker status as an employee unless the hiring party proves otherwise on three specific prongs — a substantially higher bar than federal common law. Other states have adopted their own ABC variants with differing prongs. For any research involving wage claims, benefits disputes, or workers' compensation, state-specific classification law must be identified separately from whatever federal framework applies.
