Ladies and gentlemen, Ethic is not a student of history. The eight hour work day is great. It's half what the work day was at the beginning of the industrial revolution, and the workers aren't little kids anymore (in the industrialized countries). For your edification and enlightenment, I will now quote part of my European History book.

Robert Owen. Robert Owen (1771-1858) did not have a family business to develop. The son of a small tradesman, he was apprenticed to a clothier at the age of 10. As a teenager he worked as a shop assistand in Manchester, where he audaciously applied for a job as a manager of a cotton mill. At 19, he was supervising 500 workers and learning the cotton trade. Owen was immediately successful, increasing the output of his workers and introducing new materials to the mill. In 1816, he entered a partnership to purchase the New Lanark mill in Scotland. Owen found conditions in Scotland much worse than those in Machester. More than 500 workhouse children were employed at New Lanark, where drunkenness and theft were endemic. Owen believed that to improve the quality of work one had to improve the quality of the workplace. He replaced old machinery with new, reduced working hours, and instituted a monitoring system to check theft. To enhance life outside the factory, he estaqblished a high-quality company-run store, which plowed its profits into a school for village children.
Owen was struck by the irony that in the mills, machines were better cared for than were humans. He thought that with the same attention to detail that had so improved the quality of commodities he could make even greater improvements in the quality of life. He prohibited children under 10 from mill work and instituted a 10-hour day for child labor. His local school took infants from one year old, freeing women to work and ensuring each child an education. Owen instituted old-age and disability pensions, funded by mandatory contributions from workers' wages. Taverns were closed and workers were fined for drunkenness and sexual offenses. In the factory and the village, Owen established a principle of cummunal regulation to improve both the work and the character of his employees. New Lanark became the model of the world of the future, and each year thousands made an industrial pilgramage to visit it.

The Wages of Progress

Robert Owen ended his life as a social reformer. His efforts to improve the lot of his workers at New Lanark led to experiments to crete ideal industrial communities throughout the world. He founded cooperative societies, in which all members shared in the profits of the business, and supported trade unions in which workers could better their lives. ... The Factory Act (1833) prohibited factory work by children under nine, provided two hours of daily education, and effectively created a 12-hour day in the mills under the Ten Hours Act (1847). The Mines Act (1842) prohibited women and children from working underground.

Yeah, so I didn't answer when the eight hour day became standard - the point is, stop $$$$$ing. It could be a lot worse. Stupid communists... never want to work, just want the benefits.
