When I interviewed at Hall something like 2 years ago, they said as a new EMT they only had the 3/4 12 hr shifts (I think it was Sun,M,T, e.o. W and vice versa?). Now I can't remember specifically if that was because that was the only openings available at the time, or if all new EMTs get that schedule and whichever case it's probably changed since then lol.
A little closer to LA if you're unable to move/commute to Bakersfield, my department, Glendale Fire we will almost guaranteed have an EMT Ambulance Operator application period opening up in the next few weeksor month or so. Starting pay is about 13/hr, 100% 911, in station response, transport all ALS/BLS calls (unlike some other AO programs with a mix of fire medic ALS and AO BLS ambulances, all our ambulances are AOs with the medics on the engine so you won't get cancelled just cuz it's a non routine call lol) Granted they mirror the application process to that of the FFs so it won't be apply, tedt, interview and start all in one month, more like ~9-12 so def take Bowers/AMR/ whoever tou want in the meantime
