According to The Atlantic’s Uri Friedman, Gothenburg, Sweden wants to find out what six hour work days will do for health and the economy:
In 1930, in the throes of the Great Depression, cereal magnate W.K. Kellogg decided to conduct an experiment. He replaced the three daily eight-hour shifts at his plant in Battle Creek, Michigan with four six-hour shifts. The results? The company hired hundreds of new people, production costs plummeted, and employees operated more efficiently, learning to prioritize leisure over work. Vestiges of the system remained in place until 1985.
Now the Swedish city of Gothenburg is considering a similar experiment. The governing coalition has proposed a year-long trial that would divide some municipal workers into a test and control group at the same pay rate, with the test group working six-hour days and the control group working the traditional eight. (It’s unclear how, or if, a lunch break will factor into the scheme.)
