Definition
A furlough is a temporary, authorized leave of absence from a duty or service obligation, granted by a supervising authority for a defined period of time. The term carries legal weight across three distinct contexts:
1. Military furlough. A formal grant of permission for a member of the armed forces — officer or enlisted — to be absent from active service for a specified time. The furlough does not discharge or release the service member; military obligations remain intact, and the individual is subject to recall. The furlough may be documented in writing, and the document itself is sometimes called a furlough.
2. Correctional furlough. A temporary release of a prisoner from custody, authorized by prison or correctional authorities, typically for a limited purpose such as attending a funeral, seeking employment, or reintegrating into civilian life before formal release. The prisoner remains in legal custody during the furlough; violation of furlough conditions is a separate offense and may extend the sentence or result in immediate return to confinement.
3. Employment furlough. A mandatory, employer-imposed period of unpaid leave used as a cost-reduction measure, typically short of permanent layoff. The employment relationship continues during the furlough period, and the employee retains benefits eligibility in many frameworks, but receives no compensation for the furlough period. This usage has become especially prominent in public-sector employment, where budget constraints force temporary workforce reductions without termination.
Common Language
Modern common usage (Wiktionary): A leave of absence or vacation, especially one granted to a member of the armed forces or a prisoner; the documents authorizing such leave; a period of unpaid time off used by an employer to reduce costs.
Historical common usage (Webster's 1913): Leave of absence; especially, leave given to an officer or soldier to be absent from service for a certain time; also, the document granting leave of absence.
The ordinary language definition is largely consistent with the military context but obscures a critical legal distinction: in correctional and employment law, a furlough is not a vacation or break from an obligation — it is a controlled, conditional suspension of an obligation that does not terminate the underlying legal relationship. A furloughed prisoner is still a prisoner. A furloughed employee is still an employee. This distinction matters enormously in legal disputes over benefits, liability, and status.
Common Confusion
Furlough vs. Discharge (military): A furlough is temporary and does not end the service member's military status. A discharge formally terminates military service. Historical sources sometimes blur this line, particularly in early American military law, where the terms were used loosely.
Furlough vs. Layoff (employment): A layoff typically ends or indefinitely suspends the employment relationship. A furlough preserves it. The legal consequences differ substantially — for unemployment benefits eligibility, COBRA continuation coverage, pension vesting, and collective bargaining agreement interpretation. Researchers should not assume that pre-2000 legal sources use these terms with modern precision.
Furlough vs. Parole/Supervised Release (corrections): Correctional furlough and parole are both conditional grants of liberty, but parole formally modifies the supervision structure of a sentence after service of minimum time. A furlough is a temporary, short-term release that does not alter the sentence itself.
Recognized Forms
/SUBTYPES
Military furlough: Authorized absence from active duty service for a definite period; does not sever the military relationship.
Correctional/prisoner furlough: Temporary release from physical custody under defined conditions; custody status persists.
Employment furlough: Employer-directed unpaid leave without termination; employment relationship continues.
Missionary/religious furlough: Temporary return from field assignment for rest or reporting, recognized in ecclesiastical and nonprofit employment contexts.
Why It Matters in Research
The legal meaning of furlough has migrated significantly across time and context. Researchers face two compounding problems: first, the term has expanded from a single military meaning to three legally distinct meanings; second, historical legal dictionaries reflect only the military usage, leaving correctional and employment law meanings entirely unaddressed in those sources.
In military law sources, furlough appears alongside mustering out, absence without leave (AWOL), and discharge — terms that must be carefully distinguished when reading 19th- and early 20th-century cases involving pension claims, service records, and veteran status determinations. Courts and pension bureaus sometimes treated unauthorized absence during a furlough period as AWOL, with consequences for benefits eligibility.
In correctional law, furlough programs expanded through the 1960s–1980s and became subjects of significant public and legislative controversy. Researchers examining criminal justice sources from this period will encounter furlough in the context of constitutional due process challenges (does a furlough denial require a hearing?), tort liability when furloughed prisoners commit crimes, and statutory rollbacks of furlough programs after high-profile incidents. The term's connotations are politically freighted in correctional law sources from the late 1980s forward.
In employment law, furlough as a term of art is largely a 21st-century development in the United States, though it has older roots in public-sector and union contexts. The COVID-19 pandemic produced an enormous volume of legal materials — agency guidance, arbitration decisions, and litigation — using the term in employment contexts. Researchers working in labor arbitration or public employment law must be alert to the specific definitions built into applicable collective bargaining agreements, as "furlough" is often a defined term with negotiated parameters that may differ from the general legal definition.

Historical Dictionary Support
Black's Law Dictionary (both editions) and Bouvier's Law Dictionary define furlough identically and narrowly: authorized leave from military or naval service for a fixed time, plus the document memorializing that leave. There is no daylight among the three sources on the military definition.
Bouvier adds context by positioning furlough immediately before furnage, which illustrates the essentially medieval-to-military scope of 19th-century legal vocabulary on this subject. Neither Bouvier nor Black acknowledges correctional or employment uses, which is accurate for their era but creates a significant gap for modern researchers using these dictionaries as reference anchors.
What the historical dictionaries miss entirely: the correctional furlough, which developed as a recognized legal mechanism in American corrections law through the mid-20th century; and the employment furlough, which was not a standard legal concept at the time these dictionaries were written. Researchers should treat the historical definitions as complete only for military contexts before 1920.
Jurisdictional Note
Correctional furlough programs are governed by state statute and prison regulation, and availability varies dramatically — some states have robust statutory frameworks, others have abolished furlough programs by legislation. Employment furlough law is largely shaped by federal frameworks (FLSA, FMLA, ADA, COBRA) but implemented through state unemployment insurance systems that vary in how they treat furloughed workers for benefit eligibility purposes.
