Schools and workplaces could operate a four days on, 10 days off approach under new advice to ease the spread of the coronavirus.
Keith Willison, professor of chemical biology at Imperial College London, suggested the scheme in a study for the Adam Smith Institute.
He recommended that businesses divide their workforce into two groups, so workers would be less likely to infect their colleagues.
Weekends built around Saturdays and Sundays would no longer apply, with workers' time off shifting depending on when the four days end and begin.
