If you have a business that needs to operate 24/7 then you need your Operations team to hire accordingly and then on-call should normally be unnecessary. Operations should be able to fix an emergency that is unsafe, insecure or illegal. Anything else can wait until the next working day even if management might prefer it not to because that costs money. If a business can't or won't make those arrangements (and pay the bill for them) then maybe its management team need to recognise that fully reliable 24/7 operation is not something they can guarantee and they should plan accordingly.
