Wow, you are very very skilled at playing the victim.
He doesn’t “have to” pee in a cup. He chooses to.
He doesn’t “have to” break traffic laws. He chooses to.
He’s not “forced to use his phone and drive at the same time”. He’s chosen to not buy a car mount and to not know his route.
“Throw him under the bus”? How? Do you know what this means?
If he is injured because a vehicle maintained by the company failed, he can sue the company. If *he’s* negligent, like blowing through stop signs, that’s on him.
Don’t get me wrong, if these aren’t woefully exaggerated complaints, it sounds difficult. But, you are also acting like he’s a slave and working under duress. He’s not.
Talking to management won’t work if he speaks like you do. He needs to be clear, concise, and have documented concerns with dates and specifics.
He can research laws for his state to see if there is a legal avenue.
He can refuse to drive unsafe equipment.
