Got to my first stop of the day, and my starter went. Called my sup and he asked me if I could get it running. There was a tow truck behind me so I asked him if he could give me a little push to pop the clutch. Once I had the vehicle started my sup asked me if there was anyway I could do my trip and just leave the truck running all day. Yes, he asked me if I could LEAVE THE TRUCK RUNNING ALL DAY. He didn't want to come out with another 1000 and move the work, or lose the time. His solution was to leave the vehicle running all day long. He is no longer a sup. Unbelievable what management does at times regardless of safety, or the rules.
