New data emerging from a comprehensive four-day work week pilot conducted in the UK suggests a compelling case for its adoption over conventional work structures, with participants frequently citing improved sleep quality as a significant advantage.

According to the trial’s published results, approximately 40% of the nearly 2,900 individuals who engaged in the experiment reported a reduction in sleep disturbances or instances of insomnia. The findings indicate that 45% experienced no alteration in their sleep patterns, while 15% noted an exacerbation of sleep-related issues.

This evaluation, recognized as one of the largest of its kind globally, involved 61 different companies. The statistics reveal that a substantial majority, 56 companies or 92% of those involved, have expressed an intention to perpetuate the four-day work schedule following the conclusion of the trial. Furthermore, 18 organizations have formally committed to integrating this model as a permanent operational policy.

The initiative was orchestrated by 4 Day Week Global, in conjunction with academic research bodies from Boston College, the University of Cambridge, and Autonomy. The pilot program spanned from June through December of the preceding year.

The critical role of adequate sleep in maintaining overall well-being is widely acknowledged. However, statistics from a 2016 report by the Centers for Disease Control indicate that over one-third of the adult population in the United States falls short of the recommended minimum of 7 hours of nightly sleep. While numerous factors contribute to insufficient rest, the CDC maintains that occupational demands are a suspected contributing element.

In a statement accompanying the report’s release, the agency suggested that “employers might consider modifying work schedules to ensure their workforce has sufficient time for restorative sleep.”

Much of the prevailing research within the US governmental framework concerning the interplay between work and sleep tends to focus on professions entailing extended overnight shifts, such as those in nursing or long-haul trucking. Nevertheless, even within a standard 40-hour work week, the pressures inherent in employment can exert a negative influence on sleep, extending into personal time.

A Swedish investigation conducted in 2007 established a correlation between insomnia and occupational stressors, particularly high workload demands. Subsequent research, also from Sweden in 2019, reinforced this connection by analyzing health survey data from over 3,700 individuals. A meta-analysis completed by State Farm Insurance in 2017 demonstrated that job-related pressures, including the volume of work, had a discernible impact on both the quality and quantity of sleep. The US National Institute for Occupational Safety and Health explicitly identifies sleep disturbances as an early indicator of occupational stress.

Suboptimal sleep not only poses a health risk to employees but can also detrimentally affect organizational performance by reducing productivity. A 2010 study projected that productivity losses attributed to fatigue incurred an estimated cost of $1,967 per employee annually across four corporations in the US. Additionally, a 2007 research paper revealed that nearly 38% of the American workforce experienced feelings of fatigue during their work hours.

Within the framework of the four-day work week pilot, 46% of participating employees reported a decrease in their usual levels of fatigue, while 14% indicated an increase.

Evidence suggests a four-day work week offers advantages for businesses as well

Participating companies also reported notable benefits, including an average revenue increase of 1.4% throughout the trial period. When contrasted with comparable periods under a conventional five-day work schedule, the revenue growth for participating firms averaged an impressive 35%, according to the trial’s outcomes.

The marketing and advertising sector constituted the largest contingent of businesses involved in the study, followed by professional services and then charities and non-profit organizations. Regarding employee demographics, 62% of participants identified as women, 37% as men, and 1% as belonging to another category.

A significant reduction in the perceived necessity for employees to resign from their positions was observed during the trial, with a reported 57% decrease in employee turnover. The findings also highlighted that 15% of the employees engaged in the pilot phase indicated a strong preference for the four-day week, stating that no financial incentive would persuade them to revert to a five-day arrangement.

The survey’s findings offer valuable insights into prevailing sentiments in the contemporary workplace, extending beyond the UK to influence employee attitudes globally. A survey conducted by the Adecco Group revealed that four out of ten employees reported experiencing burnout within the past year.

In addition to the observed improvements in sleep, individuals participating in the four-day week program reported other advantages associated with working 32 hours for equivalent compensation. Specifically, 39% of employees experienced reduced stress levels, and 71% reported a decrease in burnout by the trial’s conclusion.
