In many industrial countries, people work five eight-hour days or 40 hours a week. But some companies now want their employees to work just four days a week and still pay them for five. Is it too good to be true? Companies that reduced work hours have found that their employees like their jobs more and are more productive at work. Jan Schulz-Hofen set up the computer software company Planio in Berlin, Germany. Planio offered a four-day week to its 10-member work force earlier this year. Schulz-Hofen said, “It is much healthier and we do a better job if we’re not working crazy hours.” In New Zealand, a company called Perpetual Guardian tested how its employees reacted to a 32-hour workweek earlier this year. It said the workers reported feeling less pressured and more involved with the business.
