In order to be a nurse tech you already have to be enrolled in a nursing program and completed a certain number of courses...
I got my job as a tech following completion of an extern program offered by a local hospital (for students entering their final year of a nursing program). My position is contingent so I work when I can around school (so mostly weekends, more during school breaks etc). I know a few students who have contingent, part time, and full time nurse tech positions at a variety of hospitals. Many did "externships" through St John or Henry Ford, but others work at places like Botsford and Beaumont and didn't do an externship before a tech position.
To get tech positions many classmates had to call and hound the nurse recruiters until they found something. Lots of them were recommended by classmates already working there and had an "in." It's all a matter of being in the right place at the right time. You mentioned you're in the ED-- while in school I don't know anyone who has a tech position here. Most of the ED techs have an EMS background and additional training as they do many things that a floor tech does not.
You're not going to get a tech position before enrolling in nursing school
. You may be able to work as a CNA if you have taken a course, but once you're in nursing school hospitals will take you as a tech or CNA (without needing a CNA course) after the first semester.
I have a RN job lined up for when I graduate in May from the traditional program, and a few of my classmates who are techs at other hospitals also have jobs lined up following graduation on our respective units. I ran into a classmate who was in a second degree program and didn't work in the hospital during his program. He has a full time job on the unit next to mine. It took him about 5 or 6 months following his graduation but he did find something (and his is a "desirable" unit). There are jobs out there (and for new grad RNs without experience). It just takes a little persistence to find them.
You also mentioned that you're in the second degree program. Those programs are VERY fast paced, and realistically you may only have time to learn content and not have time for outside work.
Good luck in your program when you start!
