In a groundbreaking revelation following the world's largest trial of a four-day work week, a huge number of companies are still practicing shorter work weeks, with more than half committing to the change permanently. The trial, conducted over six months from June to December 2022 across 61 organizations in the United Kingdom, allowed employees the opportunity to work 80% of their usual hours for the same pay, in exchange for delivering 100% of their usual work output.

According to a report published by Autonomy, a think tank that led the trial alongside nonprofit 4 Day Week Global and the 4 Day Week UK Campaign, in collaboration with researchers from prestigious institutions like Cambridge, Oxford universities, and Boston College, a staggering 89% of the participating firms are still adhering to the policy. Even more impressively, at least 51% have made the four-day work week permanent by the end of 2023.

The report, released Wednesday, outlines overwhelmingly positive outcomes for both employees and their respective companies. Employees reported experiencing better physical and mental health, improved work-life balance, heightened life satisfaction, and reduced work-related exhaustion. What's more, these improvements have proven to be enduring, demonstrating that the benefits are not merely transient.

Juliet Schor, Professor of Sociology at Boston College, highlighted the longevity and authenticity of the positive effects, saying, "The strong findings at six months are not due to novelty or short-term impacts. These effects are real and long-lasting."

Moreover, insights from managers and CEOs at 28 of the organizations solidify the positive impact of the four-day work week on their companies. Half of the organizations witnessed a drop in staff turnover, nearly a third reported significant improvements in recruitment, and a remarkable 82% mentioned beneficial effects on staff well-being.

The report also talks about the strategies employed by organizations to sustain the four-day work week model. Adjustments to meeting protocols, communication practices, and task prioritization were named as effective means to ensure the success and continuity of the policy.

In addition to the positive outcomes observed in the trial, the report focuses the diversity of industries participating in the initiative. While close to half of the organizations hail from sectors such as marketing, advertising, and professional services, others include a wide spectrum including construction, manufacturing, retail, healthcare, and arts and entertainment.

The momentum behind the four-day work week movement has been steadily growing in recent years. This momentum has been further prompted by the shift to remote work during the pandemic, which has made millions of employees to rethink traditional work structures and make alternative arrangements that prioritize flexibility and well-being.

However, The success of the UK trial is not an isolated phenomenon. Similar experiments with the four-day work week have been tried on worldwide, including a trial in 2022 encompassing 33 companies, predominantly based in the United States and Ireland. These initiatives serve as compelling evidence of the feasibility and efficacy of shorter work weeks in boosting both individual and organizational productivity, while simultaneously fostering employee satisfaction and well-being.
