Eight-hour day movement
Movement to limit the working day to eight hours.
The eight-hour day movement, also called the 40-hour week movement or the short-time movement, was a social campaign in multiple countries aimed at setting a legal limit on daily working hours to prevent excessive and abusive labor practices. Its modern form began during the Industrial Revolution in Britain, when factory production drastically changed work conditions: shifts often lasted 10 to 16 hours, the workweek typically spanned six days, and child labor was widespread. From the 19th century onward, the eight-hour workday was gradually adopted by different nations and industries, with broad acceptance coming in the first half of the 20th century.
In 1593, King Philip II of Spain issued a royal decree, the Ordinances of Philip II, establishing an eight-hour workday for construction workers in the American Viceroyalties. An exception limited mine workers to seven hours per day. These rules also applied to Indigenous people in Spanish America, who maintained their own governance through elected mayors in "Indian republics."
During the early 1800s, Robert Owen first called for a ten-hour day in 1810 and implemented it at his socialist enterprise in New Lanark. By 1817, he advocated for an eight-hour day and coined the slogan: "Eight hours' labour, Eight hours' recreation, Eight hours' rest." In England, the Factories Act 1847 granted women and children a ten-hour day. French workers won a twelve-hour day after the February Revolution of 1848. Demands for shorter hours and better conditions were part of Chartist protests and early trade union organizing. Skilled workers in New Zealand and Australia achieved an eight-hour day in the 1840s and 1850s, but most employees did not see it widely adopted until the early to mid-20th century, through legislation across industrialized nations.
The International Workingmen's Association, at its 1866 Geneva Congress, demanded an eight-hour day, stating that limiting the workday was essential for any improvement or emancipation of the working class. Karl Marx, in *Das Kapital* (1867), argued that extending the workday harmed workers' health, causing premature exhaustion and death.
A red triangle became a left-wing political symbol in the 19th century. On Labor Day 1890 in France, workers wore red triangles to represent their demand for eight hours of work, eight hours of rest, and eight hours of leisure. This symbol i

Lore & Background
In 1593, Philip II of Spain established an eight-hour work day for construction workers in the American Viceroyalties by a royal edict known as Ordinances of Philip II, with an exception for mine workers limited to seven hours. During the Industrial Revolution, Robert Owen raised the demand for a ten-hour day in 1810 and instituted it at New Lanark; by 1817 he formulated the goal of the eight-hour day and coined the slogan 'Eight hours' labour, Eight hours' recreation, Eight hours' rest.' Women and children in England were granted the ten-hour day via the Factories Act 1847, and French workers won the twelve-hour day after the February Revolution of 1848.
The International Workingmen's Association at its Congress in Geneva in 1866 declared the legal limitation of the working day a preliminary condition for workers' emancipation, proposing eight hours as the legal limit. Karl Marx wrote in Das Kapital (1867) that extending the working day produces deterioration of human labour power and premature exhaustion and death. On Labor Day 1890 in France, workers wore a red triangle symbolizing 8 hours of work, 8 hours of rest, and 8 hours of leisure. The Second International in Paris in July 1889 decided that workers would demonstrate on May 1 to demand the eight-hour day, leading to International Workers' Day.
Reader's Guide
The eight-hour day movement is significant as a foundational labour reform that reshaped working conditions globally. Originating in the Industrial Revolution, it addressed the exploitation of workers subjected to 10-to-16-hour days, six-day weeks, and child labour. The movement's legacy includes the gradual adoption of the eight-hour day in various countries and industries, with widespread adoption in the first half of the 20th century. Key milestones include the 1866 Geneva Congress of the International Workingmen's Association, which made the eight-hour day a central demand, and the 1919 Hours of Work (Industry) Convention of the International Labour Organization, ratified by 52 countries. The movement also gave rise to International Workers' Day (May Day) and the red triangle symbol. Its influence extended to early adopters like New Zealand and Australia in the 1840s–1850s, and later to countries such as Uruguay (1915), France (1919), Belgium (1921), and Japan (1919). The movement's success was driven by a combination of labour agitation, wartime efficiency studies, fear of revolutionary movements, and international cooperation.
