4-Day Week: Pros and Cautions
This article examines the four-day workweek as a potential productivity boost and improved work–life balance, while noting substantial caveats. It highlights Erento’s 2018 German trial of a four-day week with equal pay, where sales remained comparable to other months, a 5% rise in new customer support, and noticeably better work–life balance. It also covers Perpetual Guardian’s New Zealand experiment, where 240 staff shifted to four days with no extra hours; a two‑month period showed 54% reporting better work–life balance, 78% after the test, life satisfaction up 5%, and stress down 7%. The piece discusses Treehouse’s earlier 32‑hour-week trial and its long‑term downsides, plus global surveys from Kronos’ Workforce Institute: about 45% think four days could work without interruptions and 72% would accept four days for the same pay. It notes industry and cultural factors shaping feasibility and potential productivity gains through structural improvements.
Discusses multiple 4-day week experiments and related productivity surveys; not platform/MAJOR industry shift.
