More than 3000 workers in the UK are getting an extra day off. The UK launched a four-day work week this week.

Thousands of workers across 70 companies will take part in the trial, which is based on the 100-80-100 rule, which states that employees will work 80% of their time for 100 percent of their pay.

Is the 4-day work week better? There is evidence that points to yes.

Quality of life is the new frontier for competition, and that reduced-hour, output focused working is the vehicle to give them a competitive edge, according to Joe O'Connor, chief executive of 4 Day Week Global.

A tight labor market and a ruthless battle for talent have led to the emergence of the four-day work week. There is more to the incentive than just attracting good people.

Juliet Schor is a sociology professor at Boston College and the experiment's lead researcher.

The 40-hour work week didn't become commonplace until after the Great Depression, when the government rationed work hours to help people find jobs. It used to be common to work six days a week for more than 70 hours. Henry Ford was one of the first leaders to speak out about the benefits of a reduced work week.

The experts in the UK hope that this change will become the new normal.

The business of this company has been doing better since they switched to a 4 day workweek.

The UK arm of 4 Day Week has a wide range of sectors that are participating in the pilot. We're hoping it will show that the four-day workweek is possible across the economy in the long run.

Researchers will measure how the reduced workweek affects productivity and satisfaction among employees, as well as the impact on the environment and gender equality over the course of six months.
