【職場新常態】研究：四天工作週試驗期間企業收入增加約8% Research suggests Company Revenue Increased by About 8% During Four-Day Work Week Trial

近日World Economic Forum研究顯示，將工作週縮短為四天不僅能提升生產力，同時也能增進員工的身心健康，並有效減少二氧化碳排放量。在2023年達沃斯世界經濟論壇年會上，人力資源諮詢公司Randstad CEO Sander van 't Noordende稱，這是企業必須面對的趨勢。西班牙第三大城市瓦倫西亞於2023年4月和5月間進行了四天工作週試驗計畫，成效顯著。

1. 提升生產力：研究發現員工在較短的工作時間內能完成更多的工作任務，如微軟日本報告指出生產力提高了40%。
2. 增進身心健康：參與試驗的員工體驗到了更高的自我感知健康狀態，壓力水平下降，疲勞感減少，整體幸福感和個人滿意度提升。超過九成的參與試驗員工希望繼續保持四天工作制，他們在試驗期間的幸福指數高達9.1分（滿分10分）。在英國的研究中，家庭時間有顯著提升，特別是男性員工照顧孩子的時間增加了27%。
3. 環境友好：由於通勤天數的減少，造成交通量減少，進而降低了二氧化氮的排放量和提高了空氣質量。另外，前期研究指出，減少工作時間10%可以將個人的碳足跡減少8.6%，這對於全球減排有重要意義。

試驗獲得員工近乎一致好評，97%員工希望將其永久化。企業方面，92%參與英國試驗的公司決定保留四天工作週。全球範圍內的公司報告稱，試驗期間收入增加約8%，比2021年同期高出37.55%。

在人才稀缺的世界中，四天工作週已成為企業的經營必須。Noordende建議，老闆應該像對待顧客一樣對待員工，提供靈活的工作時間和混合辦公方式，已被證實能顯著提高工作滿意度。

Recent research by the World Economic Forum shows that shortening the work week to four days not only boosts productivity but also improves the physical and mental health of employees, and effectively reduces CO2 emissions. Speaking at the 2023 World Economic Forum annual meeting in Davos, Sander van 't Noordende, CEO of HR consulting firm Randstad, described this as a trend that businesses must confront. Valencia, Spain's third-largest city, conducted a four-day work week trial program in April and May 2023, with significant results.

1. Boost in Productivity: Studies found that employees could accomplish more tasks in shorter working hours, such as a 40% productivity increase reported by Microsoft Japan.
2. Improved Physical and Mental Health: Employees participating in the trial experienced higher self-perceived health status, reduced stress levels, less fatigue, and an increase in overall happiness and personal satisfaction. Over ninety percent of the employees involved in the trial wished to maintain the four-day work week, with their happiness index reaching 9.1 out of 10 during the trial. The study in the UK also showed a significant increase in family time, especially with male employees spending 27% more time caring for their children.
3. Environmentally Friendly: The reduction in commuting days led to less traffic, thereby decreasing nitrogen dioxide emissions and improving air quality. Additionally, previous studies indicated that a 10% reduction in work hours could cut an individual's carbon footprint by 8.6%, which is significant for global emission reductions.

The trial received near-unanimous praise from employees, with 97% wishing to make it permanent. On the business side, 92% of the companies participating in the UK trial decided to keep the four-day work week. Companies worldwide reported that during the trial, revenues increased by about 8% and were 37.55% higher than the same period in 2021.

In a world where talent is scarce, the four-day work week has become a business necessity. Noordende suggests that bosses should treat employees as they would customers, offering flexible working hours and a hybrid office model, which has been proven to significantly increase job satisfaction.
