Somebody asked about nursing/hospital work. Having 20years experience in the medical field coming here, I learned that hospital jobs are acutely census-driven. And hospitals being small, for the small population, will routinely call off nurses or put them "on call" when the census goes down, which is often weekly. That means if you work a 12hr shift, you lose 12hr of pay. But then if the census sharply rises, they're scrambling to find people to work extra. So you may be called to come in on your days off, or if you're on duty and no help is found, you may get a double patient load. The same goes for radiology, physical therapy, respiratory therapy etc. EMT's work for the Fire departments, most of which are volunteer, so most of the EMT's are volunteers, people who work they're regular jobs, like police jobs, CNA,s, nurses, business managers, and come in when their beepers go off or the siren sounds. The only monetary advantage is they get their recerts and advance schooling paid for.
