Some years back I went from full-time (5 day work week) to part-time (3 day work week). For me it was absolutely worth it. My mindset and lifestyle are that of an artist: I spend all my free time writing, coding, drawing, composing music, cooking, and just generally building stuff. Money is not an issue because I don't buy anything other than what I need to survive. I'm aware I'm not the norm.
I went from 5 day to 4 day about a year ago. Absolutely worth it, even with the drop in pay. I don't have the artist lifestyle, but I'm able to support my family on my income even so.
That said, note that it's not a panacea for burnout. My current company is currently thrashing after layoffs and reorgs and general leadership incompetence, and I feel the siren call of quitting. Even in this market.
