Well I"m in the San Diego area working as a CNA in acute care and my pay is almost $12/hr for 8 hour day. If I decide to work a double its time and a half for the next 4 hours and double time the next 4 hours. Many try to get a double to get all the pay.
EMT-B's make $9-$10+/hr here. Don't know their shift schedule that would give them more. I took an EMT-B class in the summer to keep learning while I was on summer break. It was great. I know a lot of things my fellow students don't know. But to work as an EMT on a rig here you just do patient transports from one facility to the other. No real skills involved. The real guys work for the county with the fire department. They only make $9/hr for all their life-saving efforts.
But the good thing about working as an EMT-B is that if your company is not busy you sit around doing your homework. But you do have to pass a physical endurance test. The EMT's I rode with had to carry a gurney up and down the stairs to get their job. (I'm sure with a partner.) Their company was not a busy one and their was a lot of down time plus getting $10+ an hour.
The CNA work I do is hard work. But I have learned some things. Time management for one. Also I got to participate in a code and do CPR and then post-mortem care. No time for homework on the job though.
Good luck in your job hunt whatever you decide.
