>Then, in 1961-1967, they switched to 5 days per week, 8 hours per day, which finally gave the Soviets a real weekend, like those in the West.

>In 1987, the maximum number of hours was limited to 40 per week, with more in some sectors (agriculture, construction, transport), and less in others (education, art and culture, or coal mining)

>Soviets had 15 minimum days of paid holidays per week by then and 75% of workers had more than that. Workers younger than 18 were entitled to twice that. Working mothers with more than two children and less than 28 days of holidays per year, had three more days of holidays. Additionally, women had partial paid leave for infant care (<1 year), and they could take additional unpaid leave (<18 months)
