Why do any SW/QA engineer routinely accept to work night and WE? Of course this is gonna be non productive and produce only buggy crap. I expect any reasonable person to understand that, and only very naive and/or junior people to not. So just don't. What is your employer going to do? Fire you? Good, you don't want to work there anyway. And especially if you work at Apple, it is going to be easy to find a new job. Refuse to ship crap. Refuse to work in insane conditions. If you don't it is not your employer's fault. It is yours. (I'm saying that in the context of highly qualified jobs, like engineering -- it does not apply to other situations where the employer has all the power and people are easily replaceable and sometimes have a hard time to find a job.)
