When I was working I worked 60, 80, 100, up to 120 hours per week. Not as much about the money (though that was nice) but I loved my job and being a critical care RN is often exciting. But I only worked crazy hours three weeks per month. At the beginning of my fourth week I worked two 12 hour shifts on the weekend and then had five to seven days off. It was fantastic and worked well for me. Perhaps he could plan in some slow days or days off.
