Questions         Always at the forefront of forward-thinking initiatives, Sweden has striven to provide a good work-life balance for its workers. It should be no surprise that five weeks - not days - of paid vacation is a given there. People have biological and psychological needs to be met: sleep, food, and leisure time.        Sweden has also begun experimenting with the idea of six-hour workdays instead of the traditional eight. In the city of Gothenburg, Sweden’s second largest, some companies have been trying out the concept for the past year. A member of Gothenburg’s City Council has said that 40 years of a 40-hour workweek has only resulted in a society of high sick leave rates and early retirement. Workers at a nursing home that was selected to be part of the experiment took less sick leave, were less stressed, and their productivity improved over the course of the year.
