That alone is illegal as hell outside the Shaytan al-Akbar because of maximum work and rest period laws.
In a bitter irony, when I lived in the ameriKKKa, I had a job from 2011-13 which paid $8.50 an hour and until recently, was my highest-paying job ever - I also had the worst fucking living conditions ever despite this.
I only had to work a 12-hour shift once because we happened to have an urgent, large workload but was promised an extra R750 in addition to mandatory overtime pay. Of course the work period including overtime in a day is capped to 12 hours.
