There are a lot of negative comments that I find surprisingly imbalanced in how they view the employer-employee relationship.
Employers have the balance of power in almost any working relationship, and should take some responsibility in creating satisfactory employment conditions. Allowing bad management to mishandle employees is an abuse of that power. If a new employee doesn't choose to speak to HR, it's most likely because HR are doing a crap job of making new employees aware of what support they offer, if any.
Apple (the company) certainly wouldn't think for one second about breaching contracts where the benefit outweighed the risk of legal consequences. We might say "that's just business". So, why should you personally care about breaching contracts if turning up to work has such a strongly negative effect on your life?
I personally want to say to this guy: well done, you did the right thing for yourself. Find yourself better employment.
Sorry that this job didn't work out, and I'm sorry it was so bad that you felt you had to take a (small, temporary) hit to your reputation, but if you needed to get out of there so bad, it was worth it: best of luck for the future :)
