What are my chances of getting a good job?

Long story short here, I want to get my CDL, my current job is about to play out. In January 2014 I was terminated from a job ( I was a maintenance supervisor) for taking up for one of my workers who come to find out lied to me about messing up a machine. I took his word, and stuck my neck out and it bit me in the butt. Anyway got another job, been here for a year and half. My question is will the termination affect me getting a driving job with companies like Averitt, Big M, or Schneider? I don't wanna go through the school and then find out nobody will hire me because of my termination. I'm sure the place I was terminated from will say they would not rehire me. I had been at that job for 13 years. Any help will be appreciated

 

Yes, I'm 34 and have only held 4 jobs since I was 15 years old. And have worked everyday since I was 15. No unemployment periods. Never been arrested for anything. Never had a DUI or anything of sort, no accidents, and haven't had a speeding ticket in almost 10 years.

 

I'm looking at a CDL school here close by. I'm located in Tupelo, MS. My ultimate goal is to get on with Ashley Distibution. Ecru terminal is very close to me, but they require 1 year experience so gotta get that somewhere. Averitt is my first choice with all the research I have done. But I am open to others. Home time is important, I have a family so don't wanna be out months at a time. Main reason I like Averitt and Ashley.

 

Thanks for everything guys. Sure didn't wanna go through school and all that and then have a problem finding work. I'm gonna have to quit my job to go to cdl school. And can't afford to be out of work totally much over 2 months. I have savings to cover me that long maybe a little longer.
