I would quit too. I love Apple products but they come at a huge human cost. One of my best friends works there and he's always extremely stressed out. He works like 15 hour days, 6 days a week. He's constantly bailing on his obligations because Apple decides to run a conference call at a ridiculous hour of the night, or right before we go into a theater to watch a movie. Nevermind the China trips that get dragged out for weeks. I've heard from him on several occasions that there are few people who have worked at Apple longer than a few years because of the burnout.
May depend on which role or which products. I had a friend who did tech support at Apple for 10+ years and loved it, and another friend who works as a web dev and loves it as well.
I don't think either of my friends were in roles that had to fear Apple's goon squad... imagine things are different if you work on something iPhone/iPad/iOS related.
This is untrue. A family member worked on the Apple "software side", and it was insanely stressful (constant overtime, stay over weekends etc...). If the hardware guys have it worse, then it must be inhuman. I wonder what the turnover rate of Apple employees is.
