A split three-day week with workers split into "A teams" and "B teams" has been proposed as part of the economic recovery from the Covid-19 crisis.
The Royal Society for the encouragement of Arts, Manufactures and Commerce (RSA) is suggesting that firms separate their staff into two groups.
In a typical office, one team could work Monday to Wednesday and the second group could work Thursday to Saturday, the group has suggested.
It is based on a similar arrangement in South Korea, which has won praise for its handling of the coronavirus outbreak and crushing of its curve.
