Who knows the context the worker released this information? This person might have thought it was confidential and that Pegatron sanctioned it.
Just because jobs are hard to find does not give employers license to abuse employees.
Apple is a corporation. One that most of us like. But an individual's life should be more important than even the most powerful corporation.
Exactly how were they being abused? I attempted to download that 60 page document but I was not about to read all of that. Were they being beaten down, tied up and never allowed to go home, then only let loose during work time? Maybe you have the job from heaven and the perfect boss or maybe you work for yourself and your work life is great but that's not reality for most.
Many companies have bosses that are extremely difficult and hard on employees which is the main reason so many people hate their jobs.
These workers in Apple's factories better be happy they have a job, period. You wanting to keep their identity secret for leaking information and referring to them as "poor employees" for being "abused" is just plain nonsensical. Those "poor employees" can certainly relieve themselves from Apple's "abuse" and find another job too. Ever thought of that?
