This has been in place for a long time... Since 2008 apple has been PUBLISHING, willfully their on-site inspection reports (they were private before that). Many times in history apple has fired a company (yes, an entire supplier), or refused payment or shipment of merchandise for a supplier failing to meet not only local laws, but their own standards. Of all the companies FoxConn manufactures for, Apple is the SOLE company who conducts regular on-site inspections as well as "surprise" inspections. Until the suicide reports, it had been over 3 years since any other firm had an on-site labor condition inspection at all.
60 hour weeks are permitted. 10 hour shifts are permitted. Guess what, they are here in the USA too, and in FoxConn, they're required to be paid their premium rate for ANY hours over 40 in a week. Not all companies enforce such restrictions, and Chinese law does not either, and yet even with these conditions, people willfully leave employment at one company for a chance to work at foxconn.
In a population of 400,000 people, YES, you will find abuse if you go looking. Fact: the suicide rate among workers there is lower than the general US population suicide rate, lower than the specific demographic of US population on par with foxconn workers, and lower than the Chinese suicide rate for the same demographic as well.
As for dawn to dusk, I leave my house before sunrise and arrive home after sunset more days of the year than I do not. This is NORMAL if you commute more than an hour to get to work, or if you work in some fields. 6 different jobs I've had in my career I have averaged over 50 hours per week, and I can't count the number of 70+ hour weeks I've worked. At several points I've lived in crappy, leaky, dysfunctional, insect infested, apartments, or on a friend's graces not being able to afford a place of my own, while working here in the US well above minimum wage and doing said 50+ hour weeks. Everything is relative.
