"One employee, a source told Kotaku, had been working until 3 AM the night before"
Moral of the story, never work for any company until 3am.
I've been interviewed at companies where it was evident from my questions that I would make more working half time at my current employer than the hours typically worked at the prospective employer.
Really, I don't see why overtime is so rare in our industry. Not having it is more often an excuse to over utilize and under budget than to deal with extreme situations.
Besides, you're only as valuable to others as you allow yourself to be treated. An employer who is accustomed to exploiting you with ease doesn't have much impetus to improve the terms of your employment.
working long != working hard
