Definition
Permanent employment is a term of art in employment law describing an employment arrangement of indefinite duration — one that does not expire on a fixed date or at the completion of a specific task. It is distinguished from term employment (which ends on a set date) and project-based employment (which ends when a defined task concludes).
The word "permanent" is misleading. Permanent employment does not mean employment that cannot be ended. It means employment that continues until affirmatively terminated by either the employer or the employee. Under the at-will employment doctrine, which governs most private employment in the United States, a permanent employee can be discharged at any time, for any reason or no reason, absent a contract, statute, or public policy protection to the contrary.
Where an employment contract exists, "permanent employment" may carry a different weight. Courts have occasionally interpreted employer representations of "permanent employment" or "a job for life" as creating enforceable contractual obligations, but this interpretation is the exception, not the rule, and depends heavily on the surrounding facts and jurisdiction.

Common Language
Modern common usage (Wiktionary): "Permanent" means lasting or intended to last indefinitely; not temporary or impermanent.
Historical common usage (Webster's 1913): "Continuing in the same state, or without any change that destroys the essential form or nature of the thing; remaining unaltered or unremoved; stable; durable; not temporary."
The gap between common and legal meaning here is substantial and practically significant. In ordinary usage, "permanent" connotes stability, continuity, and durability — the opposite of provisional or temporary. In employment law, "permanent employment" carries none of those guarantees. It signals only that the employment has no fixed end date, not that the employee is protected from discharge. A researcher or practitioner who imports the common-language meaning into legal analysis will misread sources and misjudge outcomes.

Common Confusion
PERMANENT EMPLOYMENT vs. JUST CAUSE EMPLOYMENT: These are frequently conflated but are legally distinct. Just cause employment requires that an employer demonstrate a legitimate reason before terminating an employee. Permanent employment, as the term functions in most legal contexts, creates no such requirement. An employee can hold permanent employment (indefinite duration) and still be terminable at will. The confusion arises because unions, civil service systems, and some employment contracts bundle indefinite duration with just-cause protections — but the two features are conceptually separable and legally independent.
PERMANENT EMPLOYMENT vs. TENURE: In academic and some public-sector contexts, "tenure" functions as a stronger form of job protection, typically requiring a formal hearing or cause before discharge. Permanent employment in the general employment law sense does not carry this procedural protection unless expressly provided by contract or statute.

Why It Matters in Research
The central research trap with permanent employment is the false security its name implies. When reading historical cases, statutes, and treatises, researchers must attend carefully to what the source means by "permanent" — whether it is describing duration alone (indefinite term), a contractual guarantee of continued employment, or a civil service or union classification with specific procedural protections.
Historical sources up through the mid-twentieth century sometimes use "permanent employment" in contexts where the practical effect approached job security — particularly in labor union contracts and government employment. But the legal definition, as Bouvier's confirms, has consistently meant only indefinite duration terminable by either party. The policy landscape around that baseline has changed dramatically: the at-will doctrine, once nearly absolute, is now qualified by federal and state anti-discrimination statutes, public policy exceptions, implied covenant of good faith doctrines (in some jurisdictions), and express or implied contract theories. Researchers tracing the strength of any "permanent employment" promise must account for which of these overlays applied in the relevant time and jurisdiction.
In civil service and public employment contexts, "permanent" employment is a formal classification distinct from provisional or probationary status. The word carries administrative and procedural consequences — including appeal rights and due process protections — that do not apply to at-will employees. Researchers working in public employment law should not assume that the at-will rules applicable to private permanent employment govern.
The term also appears in immigration law, where "permanent employment" or "permanent employment authorization" refers to an employee's authorization to work without time restriction — a separate usage that is not coextensive with the employment law definition and should not be cross-applied.

Historical Dictionary Support
Bouvier's Law Dictionary provides the foundational definition: "Employment for an indefinite time which may be severed by either party." This is consistent with how courts treated the term in the nineteenth and early twentieth centuries. The Bouvier's entry does not equate permanent employment with irrevocable or protected employment — it explicitly preserves the mutual right of termination.
What Bouvier's does not address is the evolution of exceptions to the at-will rule that would eventually qualify the employer's unilateral power to sever. The definition reflects the period's strong at-will baseline. Researchers using Bouvier's in historical analysis should note that the entry captures the definitional core — indefinite duration, bilateral terminability — but does not anticipate the statutory and common law erosion of at-will employment that accelerated through the latter half of the twentieth century.

Jurisdictional Note
Montana is the only U.S. state that has legislatively abrogated the at-will rule for permanent employees: under the Montana Wrongful Discharge from Employment Act, an employee who completes a probationary period may be discharged only for good cause. In all other states, permanent (indefinite-duration) employment remains at-will unless contract, statute, or recognized public policy exception applies. International researchers should note that many civil law jurisdictions presume job security protections that would effectively convert what American law calls "permanent employment" into something much closer to just-cause employment.
