In 1842 a government commissioner went down a coal mine near Barnsley in Yorkshire and interviewed an eight-year-old girl named Sarah Gooder. Her job was to sit alone in the dark and open a ventilation door when coal carts passed. She told him she was a trapper, that she had to trap without a light, and that she was scared. Sometimes, she said, she sang when she had a light, but never in the dark. Her words, printed in an official report with drawings of children hauling carts on all fours, shocked the country. Within months Parliament had passed a law banning women, girls and young boys from working underground.

Child labor before and during industry

Children had always worked on farms and in family workshops. What changed with industry was the setting: long shifts in mills and mines, under overseers who were not family, and with machines that could maim. Early cotton mills recruited pauper apprentices, orphans and poor children sent from workhouses, who lived in mill dormitories and worked twelve hours or more a day. In the early nineteenth century children and teenagers made up a large share of the workforce in many textile mills, where small hands and low wages suited employers. Some children crawled under moving machinery to piece broken threads or clear cotton waste.

The campaign for reform

In 1830 the land agent Richard Oastler wrote a letter to the Leeds Mercury titled "Yorkshire Slavery," comparing child mill workers to enslaved people in the colonies. Reformers formed short-time committees demanding a ten-hour day. In 1832 the MP Michael Sadler chaired a parliamentary committee that heard harrowing testimony from mill workers about beatings, exhaustion and deformities.

The Sadler report was powerful but one-sided. Witnesses were chosen by reformers and were not cross-examined, and mill owners complained that the picture was exaggerated. A royal commission was sent out in 1833 to gather evidence more systematically. Its findings were less lurid but confirmed that long hours were harming children. The result was the Factory Act of 1833:

• No children under nine could work in most textile mills.
• Children aged nine to thirteen were limited to nine hours a day, and had to receive two hours of schooling daily.
• Young people aged thirteen to eighteen were limited to twelve hours a day.
• Four paid factory inspectors were appointed to enforce the rules.

Four inspectors for thousands of mills could not catch every abuse, and age was hard to prove before birth registration began in 1837. But the principle mattered: the state now accepted a duty to inspect private workplaces. Inspectors such as Leonard Horner wrote detailed reports that became evidence for further laws.

Mines, women and the ten-hour day

The 1842 Children's Employment Commission produced the report that included Sarah Gooder's testimony. The Mines Act of 1842 banned all women and girls, and boys under ten, from working underground. In 1847 the Ten Hours Act, championed in Parliament by Lord Ashley, later the Earl of Shaftesbury, limited women and young people in textile mills to ten hours a day. Since mills could not easily run without them, the act shortened the day for many men too.

Opponents argued that such laws interfered with the freedom of contract, would raise costs and drive industry abroad, and would leave poor families without needed income. These arguments were not always made in bad faith, and families did depend on children's wages. But over time reform spread to other industries, and compulsory schooling, introduced in stages from the 1870s, pulled children out of the workforce for good.

Were workers better or worse off?

Historians have argued for generations about the standard of living debate. Optimists point out that cheaper goods, more jobs and eventually rising wages benefited workers. Pessimists point to crowded cities, long hours and lost independence. Modern evidence suggests real wages for many workers rose only slowly between about 1780 and the 1830s, even as output per worker grew; the economist Robert Allen called this lag Engels' pause. Studies of soldiers' and convicts' records show that average heights, a marker of childhood nutrition and health, stalled or fell for some groups born in the early decades of the nineteenth century. Gains came, but for a generation or two, many working families paid the costs before they shared the rewards.

Worked example: judging a parliamentary report

You find a quotation from the Sadler report describing a child beaten for falling asleep at a machine. How should you use it?

• Ask who chose the witnesses: reformers selected them to make a case.
• Look for corroboration: did the 1833 commission or inspectors' reports find similar cases?
• Avoid both errors: neither dismiss the testimony as propaganda nor treat it as typical of every mill.
• State the claim carefully: abuses like this happened and were serious enough to change the law.
