If you're FT, longisland does not pay hourly. It's salaried, unless you're per diem, and in some cases part time.
You can expect $60-$65k per year full time, more if you have a lot of experience.
You can also expect to work nights, as most hopital's maternity jobs (incl PP, ante, L&D and NN) have an in house waiting list to slip into days and eves-although most Long Island hospitals have 12hour shifts in OB, not 8. Exception being post partum floors.
