they dont run as team. TE required to be on duty not driving in passenger seat while student is driving. Company drivers. added perks? maybe a hotel on occasion. I was with TE and another student. He paid for the hotels but was reimbursed. And a few nights he slept in the room while we got a taste of the truck.
Not sure on pay exactly but I do know up to a certain length of time, he will continue to get paid as long as the student remains with SNI. It could be a daily rate, but that could be an incentive to keep a student longer than necessary?
Not sure on how long a driver with SNI before you go to their school for it. You would have to adhere to any and all compnay policies and drive as such too.
