We all have personal lives where we do things employers would pay for. It doesn't follow from that that employers demanding constant availability is nothing new, we still have those personal lives, so this isn't a swap of fungible work. Even if it were, we aren't required to deal with professional bullshit in personal driving or family emergencies.
