CIC (and the whole hospital) starting at $28/hr here. Median avg gross salary is about $45k around these parts, we make almost $60k a yr w/o OT and holiday pay.
Night shift gets a 10% diff, puts us a little over $30/hr.
Yearly raise for living costs, and yearly raise provided your eval isn't bad. Going up the clinical ladder gets some thousand dollar bonus each year, and extra raises.
We don't get any differential for being ICU or CCRN cert, BSN vs ADN, etc. Instead, those are built into the clinical ladder. AFAIK 20 points gets you from RN I --> RN II.. CCRN is 10 points, having BSN is like 2 points, etc. So although they're not given a differential, it makes it much easier to get an extra raise and yearly bonus.
