A few years ago I joined an employer that doesn't have chat at all (a university, schools and government seem to be where you're most likely to find this) and after a few months I marveled over why I was getting so much done without working overtime and why I wasn't so exhausted when I got home.

I am healthier in every way (the visible change literally makes people's jaw drop), I have energy for a social life and side projects, and my work is higher quality than ever. I'm making a lot less than I could elsewhere but right now it's worth it.
