Penal labour orprison labour is a term for various kinds offorced labour thatprisoners are required to perform,[1] typicallymanual labour. The work may be light or hard, depending on the context.[2] Forms ofsentence involving penal labour have includedinvoluntary servitude,penal servitude, andimprisonment with hard labour. The term may refer to several related scenarios: labour as a form of punishment, theprison system used as a means to secure labour, and labour as providing occupation for convicts. These scenarios are sometimes applied to those imprisoned for political, religious, war, or other reasons as well as to criminal convicts.[3]
Large-scale implementations of penal labour includelabour camps,prison farms,penal colonies,penal military units,penal transportation, or aboardprison ships.[4]
Punitive labour, also known asconvict labour,prison labour, orhard labour, is a form of forced labour used in both the past and the present as an additional form of punishment beyond imprisonment alone. Punitive labour encompasses two types: productive labour, such as industrial work; and intrinsically pointless tasks used as primitiveoccupational therapy, punishment, or physical torment.
Sometimes authorities turn prison labour into an industry, as on aprison farm or in a prison workshop. In such cases, the pursuit of income from their productive labour may even overtake the preoccupation with punishment or reeducation as such of the prisoners, who are then at risk of being exploited as slave-like cheap labour (profit may be minor after expenses, e.g. on security). This is sometimes not the case, and the income goes to defray the costs of the prison.
Victorian inmates commonly worked thetreadmill. In some cases, it was productive labour to grind grain (an example of using convict labour to meet costs); in others, it served no purpose. Similar punishments included turning thecrank machine or carrying cannonballs.[5] Semi-punitive labour also includedoakum-picking: teasing apart old tarry rope to makecaulking material for sailing vessels.
In a number of penal systems, inmates have the possibility of getting jobs. This may serve several purposes. One goal is to give an inmate a meaningful way to occupy their prison time and a possibility of earning some money. It may also play an important role in resocialisation as inmates may acquire skills that would help them to find a job after release. It may also have an importantpenological function: reducing the monotony of prison life for the inmate, keeping inmates busy on productive activities, rather than, for example, potentially violent or antisocial activities, and helping to increase inmate fitness, and thus decrease health problems, rather than letting inmates succumb to a sedentary lifestyle.[6]
The classic occupation in 20th-century British prisons was sewing mailbags. This has diversified into areas such as engineering, furniture making, desktop publishing, repairing wheelchairs and producing traffic signs, but such opportunities are not widely available, and many prisoners who work perform routine prison maintenance tasks (such as in the prison kitchen) or obsolete unskilled assembly work (such as in the prison laundry) that is argued to be no preparation for work after release.[7] Classic 20th-century American prisoner work involved makinglicense plates; the task is still being performed by inmates in certain areas.[8]
Many businesses, large and small, already make use of prison workshops to produce high quality goods and services and do so profitably. They are not only investing in prisons but in the future of their companies and the country as a whole. I urge others to follow their lead and seize the opportunity that working prisons offer.
A significant amount of controversy has arisen with regard to the use of prison labour if the prison in question isprivatised. Many of these privatised prisons exist in the SouthernUnited States, where roughly 7% of the prison population are within privately owned institutions.[10] Goods produced through this penal labour are regulated through theAshurst-Sumners Act which criminalises the interstate transport of such goods.
The advent of automated production in the 20th and 21st century has reduced the availability of unskilled physical work for inmates.

Imprisonment with hard labour was first introduced into English law with theCriminal Law Act 1776 (16 Geo. 3 c. 43),[11] also known as the "Hulks Act", which authorised prisoners being put to work on improving the navigation of theRiver Thames in lieu oftransportation to theNorth American colonies, which had become impossible due to theAmerican War of Independence.[12]
ThePenal Servitude Act 1853 (16 & 17 Vict. c. 99)[14] substituted penal servitude for transportation to a distant British colony, except in cases where a person could be sentenced to transportation for life or for a term not less than fourteen years. Section 2 of the Penal Servitude Act 1857 (20 & 21 Vict. c. 3)[15] abolished the sentence of transportation in all cases and provided that in all cases a person who would otherwise have been liable to transportation would be liable to penal servitude instead. Section 1 of the Penal Servitude Act 1891[16] makes provision for enactments which authorise a sentence of penal servitude but do not specify a maximum duration. It must now be read subject to section 1(1) of theCriminal Justice Act 1948, which replaced penal servitude with imprisonment.
Sentences of penal servitude were served in convict prisons and were controlled by theHome Office and thePrison Commissioners. After sentencing, convicts would be classified according to the seriousness of the offence of which they were convicted and their criminal record. First time offenders would be classified in the Star class; persons not suitable for the Star class, but without serious convictions would be classified in the intermediate class.Habitual offenders would be classified in theRecidivist class.[17] Care was taken to ensure that convicts of different classes did not mix.
Penal servitude included hard labour as a standard feature. Although it was prescribed for severe crimes (e.g. rape, attempted murder, wounding with intent, by theOffences against the Person Act 1861) it was also widely applied in cases of minor crime, such as pettytheft andvagrancy, as well asvictimless behaviour deemed harmful to the fabric of society. Notable recipients of hard labour under British law include the prolific writerOscar Wilde, imprisoned inReading Gaol after his conviction forgross indecency.
Labour might be either arduous but pointless work intended solely as punishment, such as the treadmill, or useful. InInveraray Jail from 1839 prisoners worked up to ten hours a day; most male prisoners made herring nets or pickedoakum for caulking wooden watercraft (Inveraray was a busy herring port); those with skills were often employed where their skills could be used, such as shoemaking, tailoring or joinery. Female prisoners picked oakum, knitted stockings or sewed.[5]
Forms of labour purely for punishment included thetreadmill, shot drill, and thecrank machine.[5]
Treadmills for punishment were used for decades in British prisons beginning in 1818; they often took the form of large paddle wheels some 6 metres (20 feet) in diameter with 24 steps around a 1.8-metre (6 ft) cylinder. Prisoners had to work six or more hours a day, climbing the equivalent of 1,500 to 4,300 vertical metres (5,000 to 14,000 ft). While the purpose was mainly punitive, the mills could have been used to grind grain, pump water, or operate a ventilation system.[18]
Shot drill involved stooping without bending the knees, lifting a heavy cannonball slowly to chest height, taking three steps to the right, replacing it on the ground, stepping back three paces, and repeating, moving cannonballs from one pile to another.[5]
The crank machine was a device which turned acrank by hand which in turn forced four large cups or ladles through sand inside a drum, doing nothing useful. Male prisoners had to turn the handle 6,000 to 14,400 times as registered on a dial for six hours a day (1.5–3.6 seconds per turn). The warder could make the task harder by tightening an adjusting screw,[5] which gave rise to the slang term "screw" for a prison officer.[19]

TheBritish penal colonies in Australia between 1788 and 1868 provide a major historical example of convict labour, as described above: during that period, Australia received thousands of transported convict labourers, many of whom had received harsh sentences for minormisdemeanours in Britain orIreland.
As late as 1885, 75% of all prison inmates were involved in some sort of productive endeavour, mostly in private contract and leasing systems. By 1935, the portion of prisoners working had fallen to 44%, and almost 90% of those worked in state-run programmes rather than for private contractors.[20]

Penal servitude was abolished forEngland and Wales by section 1(1) of theCriminal Justice Act 1948.[21] Every enactment conferring power on a court to pass a sentence of penal servitude in any case must be construed as conferring power to pass a sentence of imprisonment for a term not exceeding the maximum term of penal servitude for which a sentence could have been passed in that case immediately before the commencement of that Act.
Imprisonment with hard labour was abolished by section 1(2) of that Act. Section 45(1) of the UKNational Minimum Wage Act 1998[22] excludes prisoners from entitlement to the nationalminimum wage.[23]
Penal servitude was abolished forNorthern Ireland by section 1(1) of theCriminal Justice Act (Northern Ireland) 1953.[24] Every enactment which operated to empower a court to pass a sentence of penal servitude in any case now operates so as to empower that court to pass a sentence of imprisonment for a term not exceeding the maximum term of penal servitude for which a sentence could have been passed in that case immediately before the commencement of that Act.
Imprisonment with hard labour was abolished by section 1(2) of that Act. Imprisonment with hard labour was abolished by section 1(2) of that Act. Section 45(1) of the UK National Minimum Wage Act 1998[22] excludes prisoners from entitlement to the national minimum wage.
Penal servitude was abolished inScotland bysection 16(1) of theCriminal Justice (Scotland) Act 1949 on 12 June 1950, and imprisonment with hard labour was abolished by section 16(2) of the act.
Every enactment conferring power on a court to pass a sentence of penal servitude in any case must be construed as conferring power to pass a sentence of imprisonment for a term not exceeding the maximum term of penal servitude for which a sentence could have been passed in that case immediately before 12 June 1950. But this does not empower any court, other than the High Court, to pass a sentence of imprisonment for a term exceeding three years.

During theChinese Civil War (1938–1949), theKuomintang (KMT) authorities established a series of labor and detention facilities aimed at suppressing progressive youth and activists who supported theChinese Communist Party. Young activists and students accused of supportingMao Zedong and theChinese Communist Party (CCP) were arrested and re-educated in the spirit ofanti-communism at theNorthwestern Youth Labor Camp.[26] During the Kuomintang's rule,Chiang Kai-shek carried out a brutal suppression campaign against Communist activists through theBureau of Investigation and Statistics.[27] One of the most notorious sites of repression was theXifeng Concentration Camp, where political prisoners were detained and subjected to forced labor. In the final year of Kuomintang control on the mainland, a large number of inmates were massacred as the regime retreated.[28]
After thefounding of the People's Republic of China in 1949, the systems oflaojiao (Re-education Through Labour) andlaogai (Reform Through Labour) were established as part of the country's efforts to maintain social order and rehabilitate offenders in the early stages of state-building.[29] Since the 1980s, as China advanced itsReform and Opening Up Policy, the original regulations governing re-education through labor gradually became outdated and no longer suited the evolving social environment.[30] Due to changing societal expectations and the push for advancing law-based governance, relevant legislation did not move forward, and calls for reform increased.[30] Responding to public concerns and the needs of national governance, on December 28, 2013, the Standing Committee of the12th National People's Congress adopted the Decision on Abolishing Laws and Regulations on Reeducation Through Labor, officially bringing the system to an end.[31] In subsequent years, various localities further strengthened the standardized, lawful management of correctional work; for example, in Shanghai, offenders participating in labor programs could receive compensation of up to 600 yuan per month in 2019.[32]
Prison inmates can work[33] either for the prison (directly, by performing tasks linked to prison operation, or for the Régie Industrielle des Établissements Pénitentiaires, which produces and sells merchandise) or for a private company, in the framework of a prison/company agreement for leasing inmate labour.[34] Work ceased being compulsory for sentenced inmates in France in 1987. From theFrench Revolution of 1789, the prison system has been governed by a new penal code.[35] Some prisons became quasi-factories, in the nineteenth century, many discussions focused on the issue of competition between free labour and prison labour. Prison work was temporarily prohibited during theFrench Revolution of 1848. Prison labour then specialised in the production of goods sold to government departments (and directly to prisons, for example guards' uniforms), or in small low-skilled manual labour (mainly subcontracting to small local industries).[36]
Forced labour was widely used in the African colonies. One of the most emblematic projects, the construction of the Congo-Ocean railway (140 km or 87 miles) cost the lives of 17,000 indigenous workers in 1929. In Cameroon, the 6,000 workers on the Douala-Yaoundé railway line had a mortality rate of 61.7% according to a report by the authorities. Forced labour was officially abolished in the colonies in 1946 under pressure from theRassemblement démocratique africain and theFrench Communist Party. In fact, it lasted well into the 1950s.[37]
Before 1970, there were five kinds of confinement in Germany. They wereZuchthaus (hard labor prison),Gefängnis (prison),Einschließung (jail),Arbeitshaus (workhouse), andHaft (custody). AZuchthaus was a prison of physically exerting hard labor, such as breaking rocks, where prisoners had to work, even to the point of collapse. This was repealed by the Große Strafrechtsreform ("Great Panel Law Reform") of theWest German penal code, which came into force on April 1, 1970.[38] Today, aGefängnis is known as aJustizvollzugsanstalt, or "Justice Enforcement Facility".[39]
Only convicts sentenced to "rigorous imprisonment" have to undertake work during their prison term.[40] A 2011Hindustan Times article reported that 99% of convicts that receive such sentences rarely undertake work because mostprisons in India do not have sufficient demand for prison labour.[41] In the Indian Penal Code prior to 1949, many sections prescribed penal servitude for life as a viable punishment. This was removed by Act No. XVII of 1949, known as the Criminal Law (Removal of Racial Discriminations) Act, 1949.[42]
Penal servitude was abolished inIreland by section 11(1) of theCriminal Law Act, 1997.[43]
Every enactment conferring a power on a court to pass a sentence of penal servitude in any case must be treated as an enactment empowering that court to pass a sentence of imprisonment for a term not exceeding the maximum term of penal servitude for which a sentence could have been passed in that case immediately before the commencement of the Criminal Law Act 1997.
In the case of any enactment in force on 5 August 1891 (the date on which section 1 of the Penal Servitude Act 1891 came into force) whereby a court had, immediately before the commencement of the Criminal Law Act 1997, power to pass a sentence of penal servitude, the maximum term of imprisonment may not exceed five years or any greater term authorised by the enactment. Imprisonment with hard labour was abolished by section 11(3) of that Act.[44]
Most Japanese prisoners are required to engage in prison labour, often inmanufacturing parts which are then sold cheaply to private Japanese companies. This practice has raised charges ofunfair competition since the prisoners' wages are far below market rate.[45]
During the earlyMeiji era, inHokkaido many prisoners were forced to engage inroad construction (Shūjin dōro (囚人道路)),mining,[46] andrailroad construction, which were severe. It was thought to be a form ofunfree labour. It was replaced byindentured servitude (Takobeya-rōdō (タコ部屋労働)).[47]
(Hard) penal labour[definition needed] does not exist in the Netherlands, but a light variant consisting ofcommunity service (Dutch:taakstraf)[48] is one of the primary punishments[49][which?] which can be imposed on a convicted offender.[50] The maximum punishment is 240 hours, according to article 22c, part 2 ofWetboek van Strafrecht.[51] The labour must be done in their free time.Reclassering Nederland [nl] (the Dutch parole office) keeps track of those who were sentenced to community services.[52][53]
TheCriminal Justice Act 1954 abolished the distinction between imprisonment with and without hard labour and replaced 'reformative detention' with 'corrective training',[54] which was later abolished on 30 June 2002.[55]
North Korean prison camps can be differentiated intointernment camps for political prisoners (Kwan-li-so in Korean) andreeducation camps (Kyo-hwa-so in Korean).[56] According to human rights organisations, the prisoners face forced hard labour in all North Korean prison camps.[57][58] The conditions are harsh and life-threatening[59] and prisoners are subject to torture and inhumane treatment.[60][61]
Another historically significant example of forced labour was that ofpolitical prisoners and other persecuted people inlabour camps, especially in totalitarian regimes since the 20th century where millions of convicts were exploited and often killed by hard labour and bad living conditions.[62] For much of the history of theSoviet Union and otherCommunist states, political opponents of these governments were often sentenced to forced labour camps. These forced labour camps are called Gulags, an acronym for the government organisation that was in charge of them.[63] The Soviet Gulag camps were a continuation of the punitive labour system ofImperial Russia known askatorga, but on a larger scale. The kulaks were some of the first victims of the Soviet Union's forced labour system. Starting in 1930, nearly two million kulaks were taken to camps in unpopulated regions of the Soviet Union and forced to work in very harsh conditions.[64] Most inmates in the Gulag were ordinary criminals: between 1934 and 1953 there were only two years, 1946 and 1947, when the number of counter-revolutionary prisoners exceeded that of ordinary criminals, partly because the Soviet state hadamnestied 1 million ordinary criminals as part of the victory celebrations in 1945.[65]: 343 At the height of thepurges in the 1930s political prisoners made up 12% of the camp population; at the time ofJoseph Stalin's death just over one-quarter. In the 1930s, many ordinary criminals were guilty of crimes that would have been punished with a fine or community service in the 1920s. They were victims of harsher laws from the early 1930s, driven, in part, by the need for more prison camp labour.[66]: 930
The Gulags constituted a large portion of the Soviet Union's overall economy. Over half of the tin produced in the Soviet Union was produced by the Gulags. In 1951, the Gulags extracted over four times as much gold as the rest of the economy. Gulag camps also produced all of the diamonds and platinum in the Soviet Union, and forced labourers in the Gulags constituted approximately one fifth of all construction labourers in the Soviet Union.[67]
Between 1930 and 1960, theSoviet regime created manylabour camps inSiberia andCentral Asia.[68][69] There were at least 476 separate camp complexes, each one comprising hundreds, even thousands of individual camps.[70] It is estimated that there may have been 5–7 million people in these camps at any one time. In later years the camps also held victims of Joseph Stalin's purges as well asWorld War IIprisoners. It is possible that approximately 10% of prisoners died each year.[71] Out of the 91,000 German soldiers captured after theBattle of Stalingrad, only 6,000 survived the Gulag and returned home.[72] Many of these prisoners, however, had died of illness contracted during the siege of Stalingrad and in the forced march into captivity.[73] More than half of all deaths occurred in 1941–1944, mostly as a result of the deteriorating food and medicine supplies caused by wartime shortages.[74]: 927
Probably the worst of the camp complexes were the three built north of the Arctic Circle atKolyma,Norilsk andVorkuta.[75][76] Prisoners in Soviet labour camps were sometimes worked to death with a mix of extremeproduction quotas,brutality,hunger and the harsh elements.[77] In all, more than 18 million people passed through theGulag,[78] with further millions beingdeported and exiled to remote areas of the Soviet Union.[79] The fatality rate was as high as 80% during the first months in many camps. Immediately after the start of theGerman invasion of the Soviet Union duringWorld War II, theNKVD massacred about 100,000 prisoners who awaited deportation either to NKVD prisons inMoscow or to the Gulag.[80][81]
The13th Amendment of the US Constitution, enacted in 1865, explicitly allows penal labour as it states that "neither slavery nor involuntary servitude, except as a punishment for a crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction".[82][83][84] Unconvicted detainees awaiting trial cannot be forced to participate in forced rehabilitative labour programs in prison as it violates the Thirteenth Amendment. Penal labour is also sometimes used as a punishment in theUS military.[85]

The "convict lease" system became popular throughout the South following theAmerican Civil War and continued into the 20th century. DuringJim Crow, former slaves were often arrested and worked in much the same way as before the war. Since the impoverished state governments could not afford penitentiaries, they leased out prisoners to work at private firms. Reformers abolished convict leasing in the 20th-centuryProgressive Era.[86] At the same time, labour has been required at many prisons.
In 1934, federal prison officials concerned about growing unrest in prisons lobbied to create a work program.Federal Prison Industries (FPI;doing business as UNICOR since 1977) is a wholly ownedUnited Statesgovernment corporation created in 1934 that uses penal labour from theFederal Bureau of Prisons (BOP) to produce goods and services. FPI is restricted to selling its products and services, which include clothing, furniture, electrical components and vehicle parts, to federal government agencies and has no access to the commercial market so as not to compete against private employment.[87]
By 1979, private interests were once again invited into this economy of incarceration. Through thePrison Industry Enhancement Certification Program (PIECP), Congress allowed private companies to directly profit from prison labor under the guise of providing "employment opportunities" to inmates. This marked a return to a profit-driven model that blurred the line between punishment and exploitation.State prison systems soon followed, establishing their own penal labor divisions—further entrenching the economic dependence on inmate work and blurring the moral boundary between correction and commodification.[88]
From 2010 to 2015[89] and again in2016[90] and2018,[91] some prisoners in the USrefused to work, protesting for better pay, better conditions and for the end of forced labour. Strike leaders have been punished with indefinitesolitary confinement.[92][93] Forced prison labour occurs in both public andprivate prisons. The prison labour industry grosses over $1 billion per year selling products that inmates make, while inmates are paid very little or nothing in return.[94] In California, 2,500 incarcerated workers fightwildfires for $1 an hour through the CDCR'sConservation Camp Program; the voluntary participation of prisoners in this work saves the state as much as $100 million a year.[95]
In 2016,Mississippi inmates removedtrash fromhighways to save theDepartment of Transportation money.[96] The prison strikes of 2018, sponsored by Jailhouse Lawyers Speak and theIncarcerated Workers Organizing Committee, are considered the largest in the country's history. In particular, inmates objected to being excluded from the13th Amendment which forces them to work for pennies a day, a condition they assert is tantamount to "modern-day slavery".[97][98][99]
Correctional standards promulgated by theAmerican Correctional Association provide that sentenced inmates be required to work and be paid for that work.[100] Some states, such as Arizona, require all able-bodied inmates to work.[101]
Much of the work imposed on prisoners—often routine "prison housework" rather than economically productive activity.[102] An analysis of theInternational Trade Union Confederation's report in 2025 indicates that the United States has not effectively adhered to the labor conventions it has ratified,[103] thereby failing to realize its commitments to the protection of workers' rights.[104][105]
As a rule the work of prisoners is performed under compulsion
