People are constantly asking me if work/life balance exists for developers. While it's certainly not the norm, there are companies who have built their culture around having it.
I put together a page listing all the companies that selected "Work/Life Balance" as one of their top 8 key values, and thought I'd share it. People's definitions of work/life balance vary wildly, so you can see how different teams talk about what it means to them, and make your own judgment.
Hope it's helpful!
