I have,on more than one occasion,gone toe to toe with management over this issue. I`m fair about it,as mentioned above I won`t refuse to bring a load back because of a marker or maybe one of the tail lights. But a completely dark tlr because of an electrical failure,no. Something more serious,structural or suspension,then the trailer isn`t going anywhere. Another sometime issue is the "hot load" that was just wrapped up and needs to get to the railyard by its cutoff. Problem is the only way to get it there is to speed. Sorry,it ain`t going to happen. I`ve been threatened over this enough times that they know to not even look at me if these trailers come up. But they find someone to do it and the dice are rolling as to when someone finally balls one up and maybe hurts someone.
The tip mentioned above,having it in writing,works well. So does pulling a witness over to hear and see the person direct you to work or else.
The one thing I`ll tell every rookie in feeder is that at the end of the day even if you no longer have a job the primary goal in your life is to go home in one piece. Making sure others do also is goal number two.
