The most important but examine on a four-day workweek included 141 corporations, 90 p.c of which retained the association on the finish of the six-month experiment
Transferring to a four-day work week with out shedding pay leaves staff happier, more healthy and higher-performing, in line with the largest examine of such an intervention thus far, encompassing six nations. The analysis confirmed {that a} six-month trial of working 4 days per week diminished burnout, elevated job satisfaction and improved psychological and bodily well being.
The examine’s authors had questioned whether or not a condensed working week would add to staff’ stress. “When staff need to ship the identical productiveness, they may work very quickly to get the job completed, and their well-being would possibly truly worsen,” says lead writer Wen Fan, a sociologist at Boston Faculty in Massachusetts. “However that’s not what we discovered.” As an alternative, workers members’ stress ranges fell.

Pandemic upheaval
Ranges of worker stress and burnout soared throughout the COVID-19 pandemic, main many staff to give up their jobs, the authors be aware. The consequence was giant numbers of unfilled positions in some labour markets.
To see whether or not shorter weeks may be the antidote for poor morale, researchers launched a examine of two,896 people at 141 corporations in Australia, New Zealand, america, Canada, Eire and the UK.
Earlier than making the shift to diminished hours, every firm that opted into the overhaul was given roughly eight weeks to restructure its workflow to keep up productiveness at 80% of earlier workforce hours, purging time-wasting actions resembling pointless conferences. Two weeks earlier than the trial began, every worker answered a collection of questions to judge their well-being, together with, “Does your work frustrate you?” and “How would you price your psychological well being?” After six months on the brand new schedule, they revisited the identical questions.
Total, staff felt extra glad with their job efficiency and reported higher psychological well being after six months of a shortened work week than earlier than it.
Winners and losers?
A typical criticism of the four-day work week is that staff can’t produce the identical output in 4 days as in 5. The examine didn’t analyse company-wide productiveness, but it surely provides a proof for the way staff might be extra environment friendly over fewer hours. “When persons are extra effectively rested, they make fewer errors and work extra intensely,” says Pedro Gomes, an economist at Birkbeck College of London. However Gomes wish to see extra evaluation of the impacts on productiveness.
Fan notes that greater than 90% of corporations determined to maintain the four-day work week after the trial, indicating that they weren’t frightened a few drop in income.
The authors additionally checked out whether or not the optimistic impacts of shorter work weeks would wane as soon as the system misplaced its novelty. They collected knowledge after staff had spent 12 months after the beginning of the trial and located that well-being stayed excessive.
However as a result of corporations signed up for the trial voluntarily, the outcomes would possibly overestimate the true impact of the four-day work week throughout a spread of corporations. And since all outcomes have been self-reported, staff might need exaggerated the advantages within the hope of holding their further time off. The authors name for randomized research to check the scheme.
