Tea is picked by hand at a scale almost no other crop matches, and the world has never settled on one way to pay for that labour. Three systems operate side by side across the producing countries: a resident estate wage, paid partly in cash and partly in housing, rations, and other benefits the company supplies rather than sells; a smallholder price per kilogram of green leaf, in which the grower is not an employee at all; and a hired casual wage sitting beneath either system, paid by a factory or a farmer rather than by any law. What a Tea Garden Worker Earns sets out what each system pays today, country by country. This is the reference on the systems themselves: where the resident-labour model came from, what the law asks of it, and where a century of trying to regulate tea labour has and has not closed the gap.

Three systems, one crop

The resident estate model is the oldest and still the dominant one in India and Sri Lanka. A worker lives on the garden, is paid a notified daily wage set by the state or a wage board, and receives housing, a food ration, and access to a school or a clinic as part of the deal rather than as a discretionary benefit. Who Grows It sets out how that model divides against the newer smallholder sector, in which a farmer owns a few acres, sells green leaf to a separate factory, and is paid a per-kilogram rate that rises and falls with the auction, not a wage at all. Kenya's cooperative system, run through the Kenya Tea Development Agency, is the clearest large-scale version of the second model. Underneath both sits a third, less visible system: hired casual labour, workers a smallholder or a factory brings on for the picking season, paid directly by whoever hires them, covered by neither an estate's statutory housing obligation nor a cooperative's payout structure. The three systems price different things. The first prices a worker's day. The second prices the leaf. The third prices neither in any way a regulator tracks closely.

The bargain a 1951 law wrote down, and what it still misses

India's Plantation Labour Act, passed in 1951, is the clearest statement of what the resident-labour bargain is supposed to be: an estate that pays a lower cash wage than an ordinary factory job is required, in exchange, to provide housing, drinking water, medical care, and schooling for its workers' children. The law formalized a deal the industry had structured around itself for a century, that a plantation is not just a workplace but a small, self-contained settlement the company runs.

That settlement model has its own origin, and it is older and larger than any single wage dispute. India's Tea Industry traces the founding recruitment drive itself, the single deadliest documented wave of 1863 to 1866. The fuller, longer-run demographic picture behind it comes from a Hindi-language history of Assam's tea garden community: British planters recruited an estimated 419,841 indentured labourers into Assam across the wider 1877 to 1929 window, a total that breaks down as roughly 162,000 men, 120,000 women, and 138,000 children, brought from the central and eastern districts of what are now Jharkhand, Odisha, Chhattisgarh, West Bengal, and Andhra Pradesh to clear forest and build the gardens by hand. Workers lived in barrack-style "coolie lines" allotting barely twenty-five square feet per person, and for the whole 1865 to 1881 period one plantation's payroll fixed a man's wage at five rupees a month and a woman's at four, against twelve to sixteen rupees for a railway labourer doing comparable work at the time. Estate hospitals were rare before 1889, and the same source records thousands of workers dying annually of disease in years before basic medical care existed on the gardens at all. The community those recruits founded has not left. It now numbers an estimated seven million people, close to a fifth of Assam's entire population, still concentrated in the upper Assam districts where the gardens are thickest.

That history is why the 1951 Act reads the way it does: not a generous add-on, but a codified floor under a system that, left to itself, had provided almost nothing. It is also why the gap between what the law asks and what a worker actually receives is the more useful question than the law's existence. A 2020 study in the International Journal for Equity in Health, based on 16 focus groups with 134 women workers across three plantations in Assam's Jorhat district, found the ration guarantee running short in practice, a private-plantation entitlement of six kilograms of rice and wheat flour every twelve working days that "almost all" of the women surveyed said they typically received less of, alongside inadequate latrines that left many women defecating in the plantation grounds for lack of working facilities, and only one of the surveyed private plantations running a crèche, and that one open only to permanent workers' children. The same study found women making up more than half of the plucking workforce, the labour-intensive, lowest-paid tier of garden work, and linked the conditions to a measurable health gap: Assam's maternal mortality rate stood at 237 per 100,000 live births against a national figure of 130, in the 2009 data the study cites. Housing, rations, and a clinic are what the law promises in place of a market wage. Whether a worker actually receives all three, on a given estate in a given year, is a separate fact from whether the law exists, and it is the fact that keeps recurring in ground-level surveys.

A 1958 international standard almost nobody who grows tea has signed

Tea labour is also the subject of its own dedicated international treaty, and the treaty's short ratification list is itself informative. The International Labour Organization's Plantations Convention, adopted in 1958 and in force since January 1960, sets minimum standards for plantation workers' wages, housing, and medical care across the tropical export crops, tea among them. As of the most recent count, only twelve states have ever ratified it, and Sri Lanka is the sole major tea producer among them. India, the world's second-largest producer and the country with the deepest and oldest resident-labour system in tea, has never ratified the convention. Neither has Kenya, the largest African producer and the home of the world's biggest smallholder cooperative system. A treaty written specifically for plantation labour, in an industry built almost entirely on plantation labour, binds only one of the trade's major origins, and the other two regulate the same ground through domestic law alone, with no international floor underneath it. A 2010 academic review of the convention in the International Journal of Sociology of Agriculture and Food put the same fact in structural terms: only a minor share of the world's plantation crops are grown under a ratifying government at all, which the review treats as evidence the convention's own definition of a plantation has fallen behind the industry it was written to cover.

When the labour system made a workforce stateless

Sri Lanka's version of the resident-labour story took the most extreme turn of any producing country, and it ran through citizenship law rather than wage law. The estate workforce the British assembled in Ceylon was, like Assam's, recruited from South India, in this case Tamil labourers brought from Tamil Nadu beginning in 1827 to clear and work the island's coffee, then tea, plantations. When Ceylon became independent in 1948, the new government's first acts included the Ceylon Citizenship Act of 1948 and a companion 1949 law, which together stripped the estate Tamil population of the nationality and voting rights an ordinary path to citizenship would otherwise have given long-resident workers. By 1952, the group could no longer elect a single representative to parliament. The population affected was not small. India and Ceylon negotiated a resolution in the Sirima-Shastri Pact of October 1964, which set out to repatriate about 600,000 of the estate Tamil population to India and grant roughly 375,000 more Ceylonese citizenship. Implementation ran far behind the pact's own numbers, per a Canadian government research review of the agreement: by October 1981, India had repatriated a little over 300,000 people and Sri Lanka had granted citizenship to about 185,000, plus 62,000 children born after the pact, leaving roughly 250,000 people still holding Indian citizenship while they waited to be moved. India declared the pact's implementation period lapsed in 1982, and the outbreak of civil war in 1984 halted the repatriation ferry service before the backlog cleared. Sri Lanka only resolved the last of the group's stateless individuals in 2003, close to four decades after the workforce's own union, the Ceylon Workers' Congress, formed in 1950 specifically to represent it. For an industry whose resident-labour bargain already runs on housing and rations rather than a market wage, a labour force the state does not recognize as its own citizens is a supply-side risk with no real parallel in any other producing country: for the better part of four decades, Sri Lanka's plantation companies drew their pickers from a population with no guaranteed right to remain in the country, to organize on the same legal footing as a citizen, or to bargain from anywhere but the estate that housed them.

Certification promises an audit the ground does not always support

Wages, unions, and citizenship are three ways the labour question surfaces in policy. A fourth is the consumer-facing certification seal, and its track record is the least reassuring of the four. A 2015 BBC investigation into Assam estates supplying Lipton, Tetley, Twinings, and PG Tips documented poor sanitation, no reliable electricity or running water in worker housing, inadequate protection during pesticide spraying, and full-time work by children in their early teens, findings the reporting set directly against the labour standards those brands' own supply chains are meant to enforce. Rainforest Alliance, whose certification seal appeared on tea from the estates in question, conceded to the BBC that the investigation had exposed flaws in its own auditing process. The finding echoes a broader one from labour economist Eric Edmonds' research on child labour regulation generally, that a minimum working age written into law, on its own, has little measurable effect on how much child labour actually occurs, because the law changes what is permitted without changing what a poor household needs its children to earn. A seal on a box states that an audit found no violation on the estate audited, on the day it was audited. It does not state that the underlying economics the 1951 Act, the 1958 convention, and the wage boards all try to address have themselves been resolved, and the premium a certified estate actually receives for meeting the standard is its own separate, and separately incomplete, story.

What the labour system is a floor under

Every one of the mechanisms above, the 1951 Act's in-kind entitlements, the 1958 convention's ratification gap, Sri Lanka's decades-long citizenship fight, and a certification seal's limited reach, is an attempt to put a floor under the same underlying fact: labour is the largest single cost in growing tea, and the margin a grower or an estate keeps out of a box of tea sold at retail runs to the low single digits, out of which the wage, or the in-kind housing and ration that stand in for part of it, still has to be paid. None of the systems above has fully closed that gap, and each leaves a different piece of it exposed: a ration that runs short, a convention that was never signed, a citizenship that took forty years to restore, a seal that certified an estate the BBC could still document child labour on. The labour question in tea is not one problem with one fix. It is the same cost pressure showing up in four different institutions, each built to answer it and each still short of doing so completely.
