And I often wonder if on call is justifiable “because you make more money than most professionals”.
It was pretty great, I took a week shift every month or so except when I was going on holiday, and aside from lugging a backpack with my laptop everywhere, didn't affect my life at all except 1 or 2 minor issues
Also, if you can get an equivalent role with less requirements such as being on call, then I guess it is just a question of grabbing it!
I wouldn't call this a permanent on-call, just being responsive.
But it depends on stability of your service. If it is messed up and people are woken up often, then you won't find many volunteers if they have other choice.
