I dunno from Ambulance -- they're load driven... by my understanding is that around here, the fire people are 3 days on, and 4 days off, or something 
similar to that.  Since they sleep in, they're effectively on-call at 
all times, and they've got enough people on a shift that they can do 
internal rotations as to who goes, unless it's a big enough call that they
all need to roll, which is a small enough percentage of calls to make 
it work.
