Unironically I love reforms like this, though

https://en.wikipedia.org/wiki/Soviet_calendar#Work_weeks

During the second half of May 1929, Yuri Larin (Юрий Ларин, 1882–1932) proposed a continuous production week (nepreryvnaya rabochaya nedelya = nepreryvka) to the Fifth Congress of Soviets of the Union, but so little attention was paid to his suggestion that the president of the Congress did not even mention it in his final speech. By the beginning of June 1929, Larin had won the approval of Joseph Stalin, prompting all newspapers to praise the idea.

Eighty percent of each factory’s workforce was at work every day (except holidays) in an attempt to increase production while 20% were resting. But if spouses, and their relatives and friends, were assigned different colors or numbers, they would not have a common rest day for their family and social life. Furthermore, machines broke down more frequently both because they were used by workers not familiar with them, and because no maintenance could be performed on machines that were never idle in factories with continuous schedules (24 hours/day every day). Five-day weeks (and later six-day weeks) “made it impossible to observe Sunday as a day of rest.[1]

I really do love novel organizational reforms like this, a shame it didn’t work out!
