neither do i. all of the on-call folks I know must respond to pages; they don't have the option to pass on them.
that's just the existing on-call model. it's quite easy to imagine that a service overprovisions to account for people not being required to accept a "page". that overprovisioning specifically is so that people can hold multiple on-call type jobs simultaneously.
But I think if Uber and Lyft are required to pay their employees an hourly rate they would then require them to respond to every page for their scheduled shift.
