I worked full-time for 1.5 years and it was the most miserable time. Maybe because I wore a suit and worked in a place where everyone was politically right-wing. Whatever the reasons, every middle of the week I'd have a small breakdown. My view was that if life was going to be like that, I didn't want it.
Part-time work made things so much better, but I must be 'regressing', because now that I work from home even going to an office part-time feels like a form of slavery. I think it's got to do with me having radical views and at the same time pretending to fit in, there's this big gap between the public and private personas and it was making me miserable. The best workplace I had was still hierarchical, and what seemed like a dream job to many people, to me was a source of misery and resentment.
Personal history aside, I think part-time work is almost always better. It is easy to be busy. Household tasks (cleaning, cooking, gardening, pet care), volunteering, or having any kind of interest fill up the time. 'Work' is good for you, but it has to be varied and meaningful. It might be different for people who find it hard to get out of the bed in the morning, but I don't think that a 40 hour week is a viable solution. I expect the 4-day week to be introduced in the near future, as the national mental health crisis mounts. None of my full-time colleagues were happy or healthy.
