In 1926, US automaker Henry Ford shortened its employees' workweek from six eight-hour days to five, with no pay cuts. It's something workers and labor unions had been calling for. Ford wasn't responding to worker demands； he was being a businessman. He expected increased productivity and knew workers with more time and money would buy and use the products they were making. It was a way of encouraging consumerism and productivity to increase profits, and it succeeded.
Since standardization of the 40-hour workweek in the mid-20th century, everything has changed but the hours. If anything, many people are working even longer hours, especially in North America. This has a severe influence on human health and well-being, as well as the environment. Until the Second World War, it was common for one person in a family, usually the oldest male, to work full-time. Now, women make up 42 percent of the world's full-time workforce. Technology has made a lot of work unnecessary, with computers and robots doing many tasks previously performed by humans.
Well into the 21st century, we continue to work the same long hours as 20th century laborers, using up ever more of Earth's supply to produce more goods that we must keep working to buy, use and replace in a seemingly endless cycle of hard work and consumption. It's time to pause and consider better ways to live like shifting from fossil-fueled lifestyles with which our consumer-based workweeks are connected.
The UK think tank, New Economics （经济学）Foundation, argues that a standard 21-hour workweek would address a number of interconnected problems： "overwork, unemployment, over-consumption, high carbon emissions, low well-being, and the lack of time to live sustainably, to care for each other, and simply to enjoy life".
Economic systems that require constant growth on a finite （有限的）planet don't make sense. It's time for a change in our economic thinking.
