"The eight-hour day movement or 40-hour week movement, also known as the short-time movement, was started by James Deb and had its origins in the Industrial Revolution in Britain, where industrial production in large factories transformed working life. The use of child labour was common. The working day could range from 10 to 16 hours for six days a week."[1]

It is the second time this month that this misconception about Ford comes around, I am curious to know where it comes from.
