Rising employers worldwide are switching to a four-day week, making workers happier and organisations stronger.

Written by the head of the UK's 4 Day Week campaign, this easy-to-follow guide shows how businesses, charities, and government organisations can reap the benefits of introducing smarter working.

It takes anyone considering modernising their hours through the current academic evidence for the benefits of introducing a four-day week – with no loss of pay.

It tackles:

1. The productivity improvements that flow from more energised and focused staff
2. The typical challenges faced in running a trial, including part-time workers and bank holidays
3. The different approaches to introducing a four-day week, such as staggered and fifth-day stoppage

The 4 Day Week Handbook features case studies from the British economy. There are tips for improving the output of a business and a resources section with the essential information you need to start making progress, including a list of academics and researchers who may be able to help.

As the leader of the 4 Day Week Campaign in the UK, Joe Ryle has years of practical experience working with organisations that have adopted more flexible working.

Explaining why companies are changing, he charts the changes to our working lives over time. At the turn of the 20th Century, workers routinely toiled for six days a week. Then the Ford Motor Company invented the five-day working week, and the 'weekend'.

Now, with longer commutes and more family members employed, the five-day working week no longer works for employers or employees. Stressed-out workers stagger home on a Friday evening and take the weekend to recover, while productivity stagnates.

The 4 Day Week Handbook cites the evidence that shortening working hours provides major benefits for the health and welfare of staff – and employers. During a trial involving 2,900 workers at 61 organisations in the UK, sick days fell by 65% (improving productivity). Staff felt much more loyal to their bosses.

Companies’ revenue stayed broadly the same, rising by 1.4% on average.

Almost all employers who piloted a four-day week continued operating one after the trial ended.

The 4 Day Week Handbook charts the many benefits of working smarter, not harder.

Better work-life balance

A four-day week with no loss of pay gives workers the time to live happier and more fulfilled lives, allowing for those non-work parts of life that are often neglected:

• rest – sleep and physical, mental, social, emotional and sensory rest
• parenting –reducing the use of paid childcare
• leisure – spending time with family and friends and pursuing hobbies and passions
• 'Life Admin' – shopping, cleaning, managing household finances

A four-day week with no loss of pay lowers the financial and environmental costs of commuting.

Higher performance and profits

Real-world examples show that employers who move to a four-day week improve productivity and cut costs. In 2021, the Henley Business School estimated that UK businesses would save a combined £104 billion a year if all the UK worked a four-day week.

Reducing the working week enables organisations to attract and retain high-quality employees who are happier and less stressed.

More sustainable lifestyle

More free time allows citizens to cycle and walk instead of driving and cook with fresh ingredients rather than buying energy-intensive ready meals.

Research has shown that a four-day week could reduce the UK's carbon footprint by 127 million tonnes per year. That is the equivalent of taking Britain’s entire private car fleet of 27 million cars off the road.

The business and human resources case for introducing a 4-day week at your office, shop or factory is clear. This succinct and practical book shows how to make the change.
