But being on call and suddenly having to fix an urgent issue takes the more energy: warm-up energy, context switching from dining with the family or playing with the kids, or being woken up from sleep. How can that be calculated so that nobody gets taken advantage of? And there's a downside, if being on call becomes profitable, say pays 2X or something like that, I bet new urgent issues would be engineered so that they're taken care of while on call time.
