People working overtime, taking their work home with them, and living constantly on-call is definitely a compound problem.
Right now with such high unemployment many people are working harder because they are afraid of losing their jobs.
Other people who would work part time if they could, can't because they need to keep their benefits especially health insurance. Simultaneously some people have two or three part time jobs because the businesses they work for don't hire full time because they can't afford to pay benefits.
What a mess, I agree, it's totally time for full time to be 32 hours and benefits to be affordable, so that more people can work, and others can work less and live more.
