I came off the on-call rota on Friday evening and the first thing I did, before anything else, was turn the volume on my phone down from "wake the dead" to "ordinary human". That small act, thumb on the volume rocker, watching the bars go down, is the actual start of a weekend off. Not the leaving of the office. The lowering of the volume.
There's a particular tension that being on-call installs in you, and you stop noticing it until it lifts. It isn't fear exactly. It's a low background process, always running, that checks the phone every time you sit down somewhere it can't easily reach. Can I go to the cinema? Technically. Will I enjoy it knowing I might have to scramble out at the quiet bit and find somewhere with signal to SSH from my phone? Not really. So you don't go. You stay within a comfortable radius of a laptop and decent connectivity, and you call it relaxing.
This weekend the radius is gone. I went for a long walk on Saturday and left the laptop at home, properly at home, not in a bag in the car as a hedge. I got to the top of a hill with no signal at all and felt, for once, delighted about it rather than faintly anxious. Someone else has the pager. If it goes off, it is genuinely, completely, not my problem, and I trust the person who has it because I've sat in that chair and I know they're good.
I want to be clear that I don't resent on-call. It's part of the job, the team is small enough that it has to be shared, and I'd rather be woken by my own systems than have someone external poking at them blind. A rota that's fair and not too frequent is a reasonable ask of an engineer who runs things in production. The problem was never the duty. The problem is what continuous low-level readiness does to your sense of rest over weeks, so quietly that you forget it's there.
So the weekend has been small and unremarkable and lovely. Coffee that went cold because I was reading rather than watching a dashboard. A walk with no escape plan. An evening where I did not, even once, instinctively reach for my phone to check that a graph was still flat. Monday I pick the pager back up and that's fine. But I'd forgotten how good it feels to be properly, deliberately unavailable, and I'm writing it down so that next time I'm three weeks into a shift and grumbling, I remember that the quiet does come back.
