I heard they’re creating these positions to help train new feeder drivers through 80 hour packets and to help with conducting feeder schools. Similar to the feeder on road job but without having to supervise a group of drivers.
I would be less worried about this and more worried about getting fired and not having any recourse since you're not covered by the contract (your words paraphrased).
I was told by human resources that I would be going to driver trainER school. I have searched the threads ad nauseum and I can't get specific information about how long driver trainer school is.
