Re: " ... in line with its policy of adhering to local laws."
Not sure who you are having a dig at, Apple or the Chinese government, but:
Chinese Law limits the length of the working week to 5 days at 8 hours a day with a maximum 36 hours per month overtime. That's substantially better than the EU working time directive (48 hours/week over 17 weeks and which the UK allows employers to opt people out of by default).
Health and Safety precautions and policies are mandatory, just as they are in the UK. And they have occasionally executed people for breaking them.
There do seem to be some employers that allegedly flout the rules. You may be suggesting that Apple picks and chooses which laws to respect.
