Could Shorter Work Weeks Really Live Up To Their Hype?

While shorter hours or four-day work weeks sound like a blessing, research shows that they might not be as promising as they sound.

Have you ever wished you never had to work on a Monday? Your dream might be closer than you think. The concept of reduced working hours is gaining traction globally as organizations and governments recognize the detrimental effects of long hours on employees and employers.

This perspective is catalyzing a shift toward rethinking and reducing work hours to promote healthier life practices. For instance, the post-lockdown adoption of hybrid work models contributed to the understanding that a healthy work-life balance boosts employee satisfaction and productivity. Shorter workweeks can be achieved in different ways. For example:

• Four-day week. Apart from the weekend, you are also given a day off on Monday or Friday.
• Fewer daily work hours. You still have to work a five-day workweek, with a reduction in your daily working hours.
• Half-days off. You are given two afternoons off in a five-day workweek.

What Are The Benefits Of Reduced Working Hours?

In several countries, including the United States, United Kingdom, Germany, Sweden and Spain, trials have been carried out to test the efficiency of shorter workweeks, highlighting the following benefits:

1. Improved work performance. Shorter workweeks might encourage you to finish your work quicker and with fewer distractions. In 2020, Buffer, an American company, introduced four-day weeks. Based on their extensive trials, 34% of their employees felt more productive, resulting in Buffer permanently shifting to a four-day workweek in 2021. The reduced hours also incentivize you to be creative with your time and encourage efficiency. In their 2019 four-day workweek project, Microsoft Japan initiated collaborative online communication, reduced meetings to 30 minutes and limited meeting participants. Not only were the workers happier, they also experienced a 40% increase in productivity.
2. Improved health and well-being. Having more time to recuperate from work can positively influence your well-being. A 2022study found that upon reducing work hours to 30 hours per week, individuals experienced reduction in stress and sleep problems. A four-day week trial conducted in the USA and Ireland showed that employees experienced a 9% reduction in fatigue and 67% also experienced a drop in burnout levels.
3. Higher life satisfaction. Shorter work hours and more free time tend to improve one's perception of their life situation. A study in Sweden examined the effects of reduced work hours and canceled lunch breaks for nurses while retaining their wages. The participants reported greater life satisfaction and higher energy levels. "You get a life. I can say as much. You do get it, actually—it is unbelievable what a big difference these two hours make," a participant explained.
4. Better work-life balance. Reduced work hours can foster a healthy balance between work and leisure activities. A study found that reducing employees' work hours while retaining their full pay led to positive work-life balance. They experienced more positive emotions before work, reduced work-related worries and improved relationships with partners, colleagues and their children.

While reduced working hours might seem like a revolutionary idea from afar, reality may be more complex up close. Which brings us to:

What Are The Potential Pitfalls Of Reduced Working Hours?

Here's why ditching the time-tested five-day workweek needs to be considered carefully:

1. Monetary issues. Some companies provide shorter workweeks with salary deductions. Employees might also face issues in wage regulations and overtime pay. These can adversely impact their living standards and savings. A 2022 study found that working reduced hours left 45% of individuals worried about having low future retirement income and 33% of individuals found it harder to make ends meet.
2. Reduced employee bonding. The time crunch to complete tasks in less time can impede social aspects of the job. Some companies also shorten lunch breaks to compensate for missed hours. In such cases, employees rarely get to meet their colleagues and miss out on social interaction.
3. Higher work pressure. Reducing work hours can increase strain on employees when implemented without foresight. A four-day workweek trial conducted in the UK found that work felt more intense for 36% of the employees. Forty-five percent of employees also felt that their productivity either remained the same as before or decreased in comparison.
4. Short-term effects. Extensive research on reduced working hours has yet to establish its effectiveness in the long run. A 2022 Gallup survey revealed that the high well-being once associated with four-day workweeks leveled out to match that of the five-day workweek. Four-day workweeks also led to greater burnout than five-day workweeks.

Your desire for a shorter workweek is well-founded. However, initiating a conversation about reduced work hours with your team requires tact and consideration. You must engage in open dialogue, highlighting the potential benefits and addressing concerns to ensure a healthy consensus and eventually, a smooth transition to a work environment that accommodates diverse work styles.

Working less can improve your quality of life. It's also important to find a "psychologically safe" workplace. Learn if your employer is meeting your needs by taking the evidence-based Psychological Safety Scale.
