Next Apple ( Foxconn ) factory will be in Brazil. Since costs will be higher and labour laws are stricter don't think it will happen the same thing over there. I don't know about US working conditions but here in Japan there are factory workers who work 240 hours overtime ( 6 days a week, 8 hours overtime a day ). Rules here are being stricter now since there are many people suiciding and so on, so most factories can only allor 60 hours overtime a month. In case the workers need to work more than these 60 hours, medical evaluation is needed. Although there are people overworking still.
