20 Biggest Four-Day Work Week Companies (Oct 2024)
During the Industrial Revolution, factory workers logged 80-100 hours per week. But in 1926, Henry Ford popularized the 40-hour work week after he found that working more barely yielded an increase in productivity. It was a breakthrough in how we work. But it was also nearly one hundred years ago.
Just like how Henry Ford implemented the five-day work, today’s visionary companies have implemented four-day work weeks for better work-life balance and higher productivity.

Very informative and well-articulated post. Thank you.
This is BY FAR the most complete source of information on everything to do with shorter work hours that I’ve ever seen. Congratulations! We should talk about the abortive California legislation soon. While many shorter hours bills get stalled in legislative committee due to political maneuvering, this one is simply badly designed if what you say in your article is anywhere close to accurate. To be continued, I hope.
very nice sharing, thank you very much
Great post! Really enjoyed reading it. Your insights are spot-on and your writing style is engaging. Looking forward to more content like this!

Thank you! Updated.
This is undeniably the most comprehensive source of information on shorter work hours I’ve ever encountered. Congratulations! We should discuss the unsuccessful California legislation soon. While many bills on shorter work hours often get stuck in legislative committees due to political tactics, this particular one seems poorly crafted if your article’s assertions are even remotely accurate. Looking forward to continuing this conversation.
