In the UK at a large company, I took TOIL for out of hours working at OT rates 1.25 up to 8pm 1.5 up to midnight and Saturday and I think it was 2x plus a day on Sunday.
When I have seen this done, the amount is often inconsequential in relation to the amount of effort to be on-call. I don't love this incentive structure because the cost of being on-call is somewhat fixed up front. Needing to avoid being out of page coverage / availability and having a computer available is a high cost paid by the employee regardless of actual page-out workload. Paying for standby certainly helps, but I haven't seen standby pay match well with the perceived effort. Maybe some companies do this right, but higher negotiated upfront pay has appeared more effective in my experience.
I'm lucky though. I see recurring conversations about it on /r/devops and I'm aware not everyone is in the same situation. Some even wear it as a badge of honour that they improve reliability so they shouldn't be paid for things breaking. (Which I completely disagree with) But working after hours is working after hours - if it doesn't feel right, maybe you should have a conversation about it.
Where devops works is that there's shared call-out responsibility when things go wrong at 2am. It won't happen again because they'll take the time to fix things.
If management don't also share in the responsibility, it -might- will happen again because they won't allocate the time (and-a-half) to fix things.
Google in the US does this. I was on call for my team about once a month and at the end of the year, the bonus for merely being available was quite large. (I think it was something like $1600 a week, but I could be misremembering.)
I believe that is for SRE teams. SRE teams are much more reasonable about on-call, having enough staff to have the on-call person on-call during their workday, not at 3am their time.
SWE teams often don't have the global coverage that entails, so they just pay you extra to be close to your phone.
I’ve never been in a position where we were paid for on-call (i.e. fix prod at 2am) work. Is that not typical?
