The first factory law to protect children required inspectors because employers ignored the previous one.
In the early decades of the Industrial Revolution, children as young as five worked in British textile mills, coal mines, and chimney sweeping. The 1833 Factory Act, also known as Althorp's Act, was the first British law to include an enforcement mechanism. It prohibited employment of children under nine in textile factories, limited working hours for children aged nine to thirteen to eight hours per day, and created a system of four factory inspectors to enforce compliance.1
Earlier legislation had failed. The Health and Morals of Apprentices Act of 1802 limited working hours for pauper apprentices in cotton mills to twelve hours per day, but included no inspectors and was widely ignored.2
In the United States, the first state child labor law was passed in Massachusetts in 1836, requiring children under fifteen working in factories to attend school for at least three months per year. By 1900, an estimated 1.75 million children between the ages of ten and fifteen were employed in American industry.3
Lewis Hine, a sociologist and photographer hired by the National Child Labor Committee in 1908, documented child workers across the country. His photographs of children in mines, mills, and canneries became evidence in the campaign for federal legislation.4
The Fair Labor Standards Act of 1938 established the first permanent federal restrictions on child labor in the United States, setting minimum ages for employment and limiting hours for workers under sixteen.5 The International Labour Organization estimates that in 2020, 160 million children worldwide were engaged in child labor, an increase of 8.4 million from 2016.6
