We work in different fields, but from where I stand it doesn't feel like employers are going out of their way to foster a work/life balance or healthy, stable work environments. Speaking of work/life balance, this article (also from The Week) talks about how flexible work hours might benefit employers and hurt employees.
I've never asked for much from my employer for work/life balance other than not working a ton outside of normal hours (e.g. I haven't had children or a major family illness). It seems like the company has a pretty decent work/life balance, but I also think a lot of that boils down to company culture and the people in management that foster it. I think it's really fragile. There's nothing set in stone in the company that people will be understanding.
