Largest 4-day week trial results good news for future of work

The results of the world’s largest 4-day week trial is good news for the future of work, with new research showing that these results are largely in line with existing global evidence, further demonstrating the benefits of reduced-hour, output-focused working.

The pilot programme conducted in the UK by non-profit 4 Day Week Global, the UK’s 4-Day Week Campaign and think tank Autonomy, guided over 60 companies and almost 3 000 workers through a six-month trial of a 4-day week, with no loss of pay for workers.

This brings the global campaign’s total number of completed pilot participants to 91 companies and approximately 3 500 employees. Lead researcher, professor Juliet Schor of Boston College, says overall results show that almost every organisation will stick to a 4-day week after the trial, with 91% definitely continuing or planning to continue and another 4% leaning towards continuing. Only 4% of participants are definitely not continuing.

Participating companies rated their overall experience of the trials at an average of 8.5/10, with business productivity and business performance each scoring 7.5/10. Revenue increased by 35% over the trial periods when compared to similar periods from the previous year, while hiring increased and absenteeism decreased.

Improved employee wellbeing and health

During the trial it was also found that the health and wellbeing of employees also improved, with significant increases observed in physical and mental health, time spent exercising and overall life and job satisfaction. Rates of stress, burnout and fatigue all decreased along with problems with sleep.

Even the environmental outcomes were encouraging, with commuting time falling across the full sample by a half hour per week.

Schor says she observed an encouraging consistency in the data, with results largely steady across workplaces of varying sizes, demonstrating this is an innovation which works for many types of organisations.

“There are also some interesting differences. We found that employees in non-profits and professional services had a larger average increase in time spent exercising, while those in construction and manufacturing enjoyed the largest reductions in burnout and sleep problems.”

Behavioural scientist and new CEO of 4-Day Week Global, Dr Dale Whelehan, explained the sample produced interesting differences in gender outcomes. “While men and women benefit from a 4-day week, women’s experience is generally better for burnout, life and job satisfaction, mental health and reduced commuting time.”

4-day workweek also balances home tasks

Encouragingly, the research also showed that the burden of non-work duties appears to be balancing out, with more men taking on a greater share of housework and childcare.

Co-founder and MD of 4-Day Week Global, Charlotte Lockhart, says her team is delighted to be expanding the arguments in favour of a 4-day week with this new world-class academic research. “We look forward to adding our Australasian pilot results to this data set in the coming weeks and our European, South African, Brazilian and North American results in the coming months.”

4-Day Week Global was founded in New Zealand by entrepreneurs and philanthropists, Andrew Barnes and Charlotte Lockhart, following the world-renowned success of their pioneering trial of the 4-day week in Perpetual Guardian.

Their approach is based on the 100-80-100™ model designed by Lockhart alongside the Perpetual Guardian trial in 2018. That means 100% of the pay, for 80% of the time, in exchange for a commitment to deliver 100% of the output.

4-Day Week Global’s ambition is to make a 4-day week the new default and reduced working time the new standard.
