We considered that model, but decided against mandatory participation in off-hours on-call. The off-hours rotation is voluntary and paid. This is a trade-off in order to reduce the number of people who have to be on-call at a given time and maintain a voluntary model. Generally, though, the person on-call will be from a team that owns at least a portion of the services they’re on-call for, and the services are distributed among the two rotations thoughtfully.
