Officials in Sweden's second city, Gothenburg, want to slash the working day of some staff to six hours, in a bid to improve productivity.
They say the experiment will lead to employees taking fewer sick days and could create more jobs, the BBC reports.
Gothenburg City Council intends to test the theory that you should work to live, not live to work and that a working day from 9am to 3pm will yield only benefits.
Starting mid year, staff in one department will spend six months to a year doing a 30-hour week on the same salary as other employees who will put in an hour a day more.
Deputy mayor Mats Pilhem believes the experiment will lead to greater efficiency, less sick leave and possibly extra jobs.
