We have a program that grants a short (4 week) sabbatical every 5 years. You can add an additional 2 weeks of PTO to get to a 6 week break.
It's not an academic's typical sabbatical, but it's a nice perk to disconnect as well as force us to not be excessively dependent on a long-time veteran for daily ops.
To your last question, it's a company perk, so wasn't negotiated; my first one went very well; I caught up on some hobbies that I'd let slide and did some fun travel and am looking forward to my second one.
