Also notice that it is impossible to achieve in the real world. What company will have enough people for rotation + systems that barely fail + major bonus for oncall + time off + people who are decisively not trigger happy against your pager...
the only downside is a small rotation (3 people 1 week each) and some serious scaling issues which have made the pervious few months much worse than earlier ones. though we also have management buy in to fix the less than good parts.
It's certainly not easy to get to that point but it's entirely possible. Everything on the post you're replying to is how on-call works for me. It's not some imaginary world, it's reality.
Go to SRECon for example and talk to people there. You'll be surprised. Just because you haven't experienced it (yet) doesn't make it impossible.
Met way too many people who consider their on-call to be okay. And when digging deeper, they're being totally exploited and I wouldn't touch their positions/teams/organizations with a 10 foot pole.
People who care about on-call moved to contracting or positions where they are not on call, they're not coming back. I did and I ain't coming back ;)
