Australia Four-Day Work Week Study Data Shows Boosted Productivity
https://scienceaim.com/australia-just-proved-the-four-day-work-week-works-here-is-what-the-data-actually-says/Calling it a study is a disservice to science. As Feynman said, anything where they have to put science as a suffix is usually not science.
Take all that AI productivity and found a one-day work week company. One day of focused collaboration each week, let bots and brains chew on stuff in the interim.
Fixing the work week to just 5 days have similar issues. Some weeks will be less work and other weeks more work but you spend the same five days there. So the what you learn that matters is to spend 5 days physically there and perform a minimum workload so you don't get fired. You drag the weeks with less work and pick up inefficient habits as a result. That is what a 5 day working week teaches. Again there will be exceptions.
Now assuming this study is correct I am not surprised with the results. You just incentivized workers to get the same amount of output done with the condition that you gain 1 day off. Off course workers will find better and quicker ways of working to get that day off.
Even if we did a 4 working day week the problem of working based on time either fixed or paid by the hour remains. The incentivisation is the problem.
This is the actual problem to discuss, not the days per week.
Stressors vary a lot by industry and experience level. A senior manager in IT may do more than 40 hours a week plus be on-call with almost no stress as long as their projects are doing well. Meanwhile, there may be no sane amount of overtime pay that will convince a young guy doing roofing in his first year, and he's highly stressed out either way.
Anyone spinning this as a political issue is plain ignorant.
