I don't think a 32-hour work week would work as a truck driver. I work 4 days a week and get a 3-day weekend, but it's like 40-45 hours a week.
I don't think I could do my job at 32 hours a week due to the nature of the work, but I like not having to work 5+ days a week. I'm fine with 4 10-hour days if I can keep the 3-day weekends. 3 12-hour days would be ideal in my situation. But every industry is a little different
