If you're employer won't pay for a washout, then I guess ya need to tell them ya can't load your next load until they make arrangements to properly dispose of it. An now we're gonna go in circles a little bit. Cuz the proper place to dispose of extra product is a truck wash that will accept it, dispose of it in their drains or dumpster an wash out the trailer. Other than that the carrier needs to foot the bill for proper disposal by any legal appropriate means necessary. Ex: Landfill. Now if it's a reefer with extra food product, some things can be donated to a food bank. Some things can not be donated due to potential lawsuits for handing out bad food that say someone could get sick from. The whole notion of people talking about selling it out the back of the trailer is nonsense. Who has time on modern e-logs to stand around a truck stop trying to sell rejected product for who knows how much time it would take when ya gotta get to next load. Just pay the truck wash the extra cost for product disposal an carry on. An I know for a fact ya can do that cuz I had to dispose of multiple pallets of ham steaks at a blue beacon cuz my carrier required photo proof of product being properly thrown away by the beacon employees.
