My friend managed to do it by boiling that frog via taking Friday afternoons off. Everyone was happy with that arrangement, so he started taking entire Fridays off. Then he switched to Mondays.
Meanwhile my SO got a hard "no" on any amount of reduction. She's looking for a part time job, but it's not something employers normally advertise.
For sticky-downward values of "full time".
Of course I like the idea of having more options in the workplace but sometimes the down sides are too obvious to get worked up over it. Be thankful we can work five 8 hour days (or less). We could have the 9 to 9, 6 day a week culture that exists in some places.
Of course it might be just an observation effect, but I think that is normally controlled for.
My jobs could never spare for me to take time off, I was too valuable to the company. Yet they also survived and were able to replace me once I left. 'impossible' is mainly 'inconvenient' in company speak.
The 9/9/6 culture is common in poorer countries and also in very highly paid professions, such as in finance. It's not some 1800s ethos, but something that a lot of people everywhere suffer with today. Some of them don't even view it as suffering. I personally wouldn't like that, but it depends on your stage in life and also your particular interest in the job.
We didn't start working with 5 8 hour days from the begging. 5 8 hour days isn't some magical number. It was fought hard for, with business screaming it couldn't be done. With people killed over it. The people that fought and died for that weren't fooling themselves even though many told them they were.
I worked crazy hours when I was young. I'm not some slacker. But saying we somehow settled upon the perfect combination the very first time labor won concessions from business, and also that the human condition can never improve from where it is, it a ridiculous position.
Good thing I never said that. What I said was, if you work less then you should get paid less. On a related note, there's also nothing about any particular job that guarantees a living wage. There are many jobs that can provably not bring in enough profit to justify paying a living wage.
If you demand a 32 hour work week for the same pay as 40 now, while people abroad can work overtime 50-60 hours for a quarter to a tenth of your salary, you're essentially claiming that an hour of your time is 20x more valuable than theirs. You can demand all you want but you ultimately can't make anyone employ you.
However, pre-industrial people used to work far less than early industrial workers: around 2-4 hours a day, 3 to 5 days a week, with long break seasons.

It's also not about half-assing. If you work someone 80 hours a week, and they work as hard as they possibly can, they will still likely be less productive than if they just worked 40 hours. Because they start making mistakes, which they then have to fix, and make more mistakes while they fix those mistakes...
After a certain point, your productivity might be negative. Meaning, no employee at all might be more productive than an employee working 100 hours a week.
