People who say things like this are usually the source of problems for the people who carry pagers - this is why in DevOps world, developers now join the club. ;)

The notion that you wouldn't rotate people if you don't alert very often is not only silly, it's why I left my last two jobs. No "rotation" meant Justizin is fucking always on-call. :D
