Dozens of companies in the U.K. will begin Monday an unprecedented experiment of a four-day work week with no loss of pay for workers.

This is stated in the publication of Sky News.

Participating in the study are companies from a variety of industries, including banking, hospitality, nursing and even animation studios.

Companies will still pay workers 100 percent of their wages - as long as they maintain maximum productivity.

The experiment, which will last six months and involve 3,000 people, is positioned to be the largest four-day pilot project anywhere in the world.

The study's organizers, 4 Day Week Global in partnership with think tank Autonomy and the 4 Day Week UK campaign, are working with university scientists measuring the impact on productivity and staff well-being.

They will also assess how the four-day workweek affects the environment and gender equality.

Joe O'Connor, executive director of 4 Day Week Global, said Britain is on the "crest of the global momentum of the four-day week," as people are used to being out of the office during the coronavirus pandemic.

One of the companies involved in the study is Charity Bank. CEO Ed Siegel said the move to a four-day week "seems like a natural next step" after the pandemic.

"The 20th-century concept of a five-day workweek is no longer appropriate for 21st-century business," he said.

Talk of a four-day workweek in Britain, however, began even before the pandemic. Before the 2019 election, Labor, which was in opposition, promised to introduce a four-day week within ten years.
