who came up with the 8 hour workday
Eight-hour day Robert Owen had raised the demand for a ten-hour day in 1810, and instituted it in his socialist enterprise at New Lanark. By 1817 he had 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 in 1847. French workers won the 12-hour day after the February Revolution of 1848.[3] A shorter working day and improved working conditions were part of the general protests and agitation for Chartist reforms and the early organisation of trade unions.
Workweek and weekend In 1908, the first five-day workweek in the United States was instituted by a New England cotton mill so that Jewish workers would not have to work on the Sabbath from sundown Friday to sundown Saturday.[9] In 1926, Henry Ford began shutting down his automotive factories for all of Saturday and Sunday. In 1929, the Amalgamated Clothing Workers of America Union was the first union to demand a five-day workweek and receive it. After that, the rest of the United States slowly followed, but it was not until 1940, when a provision of the 1938 Fair Labor Standards Act mandating a maximum 40-hour workweek went into effect, that the two-day weekend was adopted nationwide.[9]
