There is a specific kind of tiredness that comes from being on call, and it isn't really about the pages. It's about the part of your brain that never fully powers down. You can be at the pub, halfway up a hill, asleep at 2am, and a small background process keeps a thread warm just in case. You learn to recognise the pattern of your own phone's buzz from across a room. You stop trusting silence, because silence might just be a notification you haven't heard yet.
This weekend I was off the rota, and I'd forgotten how much lighter that feels.
It crept up on me on the Saturday morning. I made a coffee, sat down with a book I'd been not-reading for a month, and got about three chapters in before I realised I hadn't checked my phone once. Not glanced at it, not patted my pocket to confirm it was there. It was upstairs, on silent, and the world had not ended. That sounds like nothing. After a few weeks holding the pager, it felt like a small holiday.
We went out for a long walk in the afternoon, the kind where you lose track of time on purpose. Somewhere along it I caught myself doing the on-call maths anyway, working out how far I was from a laptop, what the signal was like out here, whether I could get back inside the response window if something went wrong. Then I remembered I didn't have to, and the thought just dissolved. Lovely.
I'm not going to pretend on-call is some terrible burden. It's part of the job, the systems are ours, and there's a real satisfaction in being the person who can fix the thing at 3am when it matters. Good on-call, well-staffed, with sane alerting and a culture that fixes the noisy alerts instead of tolerating them, is entirely survivable. I've done plenty of weeks where the phone never went off and I slept fine.
But the value of a rota isn't only in who carries it. It's in the weeks you don't. The off weeks are what make the on weeks sustainable, and I think we undersell that. A handover isn't just passing the pager along; it's passing back the right to ignore your phone for two whole days. That's worth protecting. A team that quietly lets the off-weeks erode, where you're "not technically on call but could you just keep an eye on things", has broken the only thing that makes the whole arrangement work.
So I did very little of consequence this weekend, on purpose, and I recommend it. The coffee was good, the book was better, and the phone stayed upstairs. Back on the rota tomorrow, and that's fine. I feel ready for it again, which is rather the point.
