Also, unlike say a trucker, the work of doctors and nurses is very reactive to environmental conditions (feast or famine), so it allows for limited downtime where you might sneak in a nap between 20-60 minutes, or might be 100% your entire shift. It might make scheduling slightly easier is some regard, but it's actually a very expensive way to staff.
