CDL in hand ,need training

I got my CDL in July of 2009 at a school. Was placed with a major carrier ,who's name starts with a P, ends with an e, to which I was placed with a trainer who started out fine and within a day or so started to cuss me like a dog for things like an occasional gear grind or using his windshield fluid when bugs were on the windshield, says it cost him money, switched to a new trainer after a week of verbal abuse. He also started out fine and we cross countried 3 times before one day he skreeled the truck to a stop in the Mojave desert and told me get out before he cut my throat.Over the fact that he told me to get in the sleeper but I couldn't sleep, we had been at a truck stop for 3 days waiting for a load and had been doing nothing but sleeping. After the threat on my life and some get -no-where calls to dispatch I had him let me off the truck in the next town(no way I was sleeping after throat cutting threat) at which point I flew to Tennessee.Re: company had no concerns for my personal safty.Question? I loved driving, what are my options? Note: both trainers had been reporting I was a great driver to the company.Am 53 and have surveyed land for 27 years. Am no whimp!
