A widely held belief among non-medics is that there’s some degree of choice involved in coming home at 10 p.m. rather than 8 p.m. But really the only choice is whether you fuck over yourself or your patients. The former is annoying, the latter means that people die – so it’s not really a choice at all. The system runs on skeleton staff and, on all but the quietest shifts, relies on the charity of doctors staying beyond their contracted hours to get things done.
