Yes this is true. And it's a good thing to remember to ask about when applying for jobs (and seems like an entirely reasonable thing to want to know before you sign up) It was helpful when I had a more structured on-call rotation and once we switched to 3 day shifts I was able to trade off shifts so I almost never was on-call Sunday morning. Unfortunately I was also team lead on a temperamental system for a while which had many production issues, so despite the on-call rotation, things often escalated. It was not a fun year. That said it only happened a few times that year, though the constant threat of it wears on you after a while, and it's precisely that issue which lies at the spirit of the Sabbath. It's not really a day off if you're worried about the pager going off all the time and constantly checking slack, even if nothing is happening.
