How did the five-day and eight-hour work system originate?

At present, all countries in the world generally implement the 8-hour working system. In fact, the eight-hour work system was first put forward by sociologist robert owen in August 18 17. He also invented a slogan, "Eight hours of work, eight hours of leisure and eight hours of rest". 1833, with Owen's support, compassionate factory owner John do Holti and others launched a campaign for an eight-hour working day. 1866, the first international Geneva conference put forward the slogan of "eight hours of work, eight hours of self-control and eight hours of rest", requiring countries to enact laws to confirm it.

The five-day and eight-hour working system is a standard regular working day, working five days a week and eight hours a day. It's basically four hours in the morning and four hours in the afternoon. The working hours of 8 hours a day are the daily working hours of the workers who implement the fixed working system directly stipulated by the labor law. On the one hand, it embodies the protection of the physical and mental health of workers by law, on the other hand, it also protects the right of employers to use labor.
