But perhaps pay rises will stagnate and they'll gradually not be competitive with 5-day companies at full pay.
Edit: Oh, it's started already, from the article:
> "With many businesses struggling to afford 10% inflation pay rises, we're starting to see increasing evidence that a four-day week with no loss of pay is being offered as an alternative solution."
Yes, with inflation and stagnant wage growth ( even before the pandemic ) I think and hope the 4 days work solution will push for increase in productivity per working hours.
Unfortunately not every industry is suited for 4 days work. But May be UK should start with Civil Servant?
