Blame the people loading the trailer, not the driver. A properly loaded trailer should allow the driver to move the freight around that much.

You still need to fill out your log books. Also, keep in mind (although I can't confirm with Walmart), most loading and unloading is done on a schedule. You're expected to be a certain place by a certain time to meet your unloading appointment. Early? Tough. Late? Tough.
