I used to work for crown furniture movers in Auckland as a summer job while at uni 15 years ago. We regularly worked from 6.30 to 6ish often 6 days a week. And sometimes there would be special weekend jobs where we would have to move an office starting on Friday after work and finishing Sunday evening often working 15-20 hours straight if not more.
Pay was around $14 an hour (15 years ago), I don't think I got overtime unless it was Sunday work.
Work week was between 60 and 80 hours a week. A couple of guys went straight from that to a bouncer job in the evenings.
Was a great way of losing weight my first summer dropped 30 kg in 3 months.
I couldn't do it now
