一项由波士顿学院研究人员进行的全球性研究，追踪了来自六个国家的近2900名员工，并与对照组进行了比较。结果显示，在为期六个月的四天工作制（不减薪）试验中，员工的倦怠感显著降低，睡眠质量和心理健康得到改善，工作满意度也有所提升。研究还发现，尽管工作时间减少，但多数员工认为自己的生产力有所提高。这项研究为四天工作制的益处提供了新的证据，并与英国、比利时、冰岛等国的类似试验结果相呼应，表明缩短工作时间是一种有益的模式。

📊 四天工作制显著改善员工福祉：研究显示，实施四天工作制（不减薪）的员工，在为期六个月的试验后，普遍反映倦怠感减少了67%，心理健康改善了41%，睡眠问题也减少了38%。这些积极变化在未调整工作模式的对照组中并未出现，有力证明了工作时间缩短对员工身心健康的积极影响。

🚀 员工生产力与工作满意度提升：尽管工作时间减少，但超过半数（52%）的受访员工表示，他们在更短的工作时间内变得更有效率。同时，员工的工作满意度也得到了提高，这表明缩短工作时间并未牺牲生产力，反而可能通过提升员工状态来促进生产力的增长。

🌍 全球范围内推广四天工作制趋势：这项研究的结果与多国推行四天工作制的实践相符。例如，英国一项2022年的试验也发现，大多数公司认为生产力保持稳定或有所提升；比利时和冰岛等国家已开始实施或推广四天工作制，旨在提高员工福祉和生活质量，这反映了全球对优化工作模式的共同探索。

💡 工作时间缩短效果显著：研究发现，每周工作时间减少至少八小时的员工，在身心健康方面的获益最为明显。然而，即使是工作时间的微小缩减，也对所有衡量指标带来了可衡量的积极改变，这表明缩短工作时间是一种普遍有效的策略，能够为员工带来实在的益处。

A new study found four-day workweeks without pay cuts boost well-being.The study tracked 2,896 employees across six countries, who reported less burnout and better sleep.Many countries, including Belgium and Iceland, have been rolling out four-day workweeks.

If you ever feel like the five-day workweek leaves you burned out, you may not be imagining it.

A new global study led by Boston College researchers Wen Fan and Juliet Schor found fresh evidence that four-day workweeks — without a pay cut — are beneficial for employees' well-being.

Over a six-month period, the researchers tracked nearly 2,896 employees across 141 organizations in the US, UK, Australia, Canada, Ireland, and New Zealand. They also tracked a control group of 300 people working a traditional five-day workweek.

These organizations voluntarily participated in the four-day workweek trials and were given eight weeks ahead of time to restructure their workflows to maintain productivity. Some chose to eliminate activities such as unnecessary meetings to meet their new goals.

Researchers asked questions such as "How would you rate your mental health?" to evaluate workers' well-being two weeks before the trial started, and again six months into their new schedule.

According to the study's results, after six months of only working four days a week, workers self-reported less burnout, better sleep, and higher job satisfaction.

Schor, an economist and sociologist at Boston College, told Business Insider that six months into their new schedule, 67% of workers reported reduced levels of burnout, 41% said their mental health improved, and 38% experienced fewer issues with sleep. The control group of workers did not show a meaningful change in any of the metrics.

While the study did not specifically measure productivity — and the responses were self-reported — when compared to before the change in schedule, 52% of workers said they became more productive despite working fewer hours.

Employees who saw their work time reduced by at least eight hours a week experienced the biggest gains in mental and physical well-being, but even smaller reductions delivered measurable benefits across all metrics, compared to workers at 12 companies that stuck with the traditional five-day schedule.

The new findings add to a growing body of evidence in favor of the four-day model.

A widely cited 2022 trial in the UK tracked 3,300 workers at 73 companies who shifted to a four-day workweek, and most supervisors of those workers reported either stable or boosted productivity.

Belgium introduced a law in late 2022 allowing workers to compress their 40-hour week into four longer days without losing pay, while Iceland is taking a similar approach for most workers by simply reducing hours.

Lithuania allows public sector workers with young children to work 32-hour weeks at full pay, and Dubai is trialing a temporary four‑day week for public sector employees throughout the summer.
