IF someone employees you full-time, the 40-ish hours they pay for is always interpreted as whenever they need you (if they're working you are too, right?). If you're part-time the mental model is you are only available for a very specific subset of hours (which a crisis rarely honours) or the expectation is you don't respond immediately because you're not a full-time engagement. Either way you don't have to be on call 24/7
