I'd actually heard that nurses without experience and who didn't go to a good school were having problems with jobs. Nurses *with* experience generally have a lot easier time finding work. Although most people still have to start out on a night shift and then get the option to switch to days when a spot opens up.
If you are willing to move, you will have no problems finding work as an OT. Demand may not quite be as high for OTA's, but again, if you are willing to move there are jobs.
Bilingual spanish OTs and OTAs can make a lot of money in some high demand parts of the country. Like South Texas for $120K a year.
