I and another person are taking over an old batch processing system at work. The system itself is fairly stable, but interacts with some other systems which keep falling over or changing things without adequate notification. Currently there are (mostly false) alarms almost every day, usually for stupid reasons like the network falling over for a few minutes or disk use going above a fairly arbitrary level. So when the subject of weekend on-call came up we just went hard "no", and we've been discussing solutions to that ever since (adjusting cron scheduling, making alarms more forgiving, adjusting customer expectations, improving automation, etc). Importantly, we can do this because we live somewhere with employee protection, and our contracts do not mention being on call or working weekends. If you don't have that you're pretty much SOL.
