It's too much for everyone, unless your work is your life.
In jobs where 8 hours are no problem, you usually have some periods of time, where you can shut off your brain. Driving to a new location, frequent breaks in the office or practical duties for some variation.
Corporate desk jobs are awful longer than 6-7 hours.
I’d say I only get 6 hours of work done a day. With WFH I just potter about and go on my phone for the rest of it.
I felt bad about it for a while, but the alternative is that I quit and leave my employer in the shit because the team is tiny and they struggle to recruit.
I work 12hour shifts. 3 days a week. I'm telling you, that's way better. Sure the shifts are long. You won't do anything else those days. But you get used to it in a month or two. Once you do adjust, having 4 day weekends each and every week is life changing. I could never go back.
As an industrial engineer it’s amazing that this is proving effective in manufacturing environments. I’d suspected it would but much like with WFH, I assumed this was one of those things that had a chance of catching on for office workers but wouldn’t in factories.
The 40 hour work week was a massive success not because it was just right but because cutting hours so workers can rest was hugely beneficial
Funny, I work in a prominent RV company and in 2022 we went to 4 days, too. Productivity is up, morale is high, and there is zero discussion of returning to 5. I wonder if my company partook in that experiment. Has a list of companies been posted anywhere?
