Your thoughts

Personally, I wouldn't be doing it at all. It leaves you wide open for liability in case anything should happen. You aren't a legally authorized driver of their vehicles.

 

Soon they'll accuse you of leaving bread crumbs in the trucks or changing the radio station. When they damage something they'll say you did it. You've opened the floodgates. Unless you're being paid really well to move their trucks for them, I wouldn't do it.
When another driver calls you, don't answer the phone unless company policy dictates that you answer.

 

That too. Even within my own company, someone drove my truck while I was on military duty. I was extremely annoyed by it because the office never gave me a heads up, I just got back into my truck to find all my stuff on the front seat had been dumped on my bunk and on the sleeper floor, and a bunch of stuff shoved willy nilly into the cabinets. But beyond all that, because it IS "their" truck, is the fact that their temp driver used my pillows and sleeping bag. It hasn't happened since because I raised holy hell about it, tho.
Oh, and that driver also high-hooked a trailer and smashed the bunk AC condenser on the back of the cab. Took quite a bit of explaining that it wasn't ME that did it.

The position you've placed yourself in, you're a scapegoat.

 

Tell them to back their own trucks or ask for extra pay like $5.00 a truck.

 

Wait, let me get this straight. You're getting paid by the hour, yet complaining about getting another hour of pay ( for doing nothing?) I wouldn't touch their trucks, and if the boss says anything, tell them the situation, and get out the can of wax.

 

Why does the head driver have your phone number? It's best that you stop driving their trucks asap

 

You're generous. My time is important. I want 2x my hourly wage in cash. Per truck.

Mr @marshmann1979 , no one appreciates a doormat. You should never volunteer for doormat duty.

 

Actually, I spoke too soon. There were times on my route job, at some places, all the docks had dropped wagons, and I would "double drop", so I could make the delivery. Many places wouldn't let you do that, because in the past, some drivers would take off after their delivery, and not put the wagon back.

 

Either way he deserves extra money otherwise if he doesn't say something his boss will continue taking advantage of him.
