So, I pick up a couple of trailers at a fairly big hub. One of the many problems there, is loaders, sups and all re-entering trailers after they have been cleared to couple or even pull! I had a part-timer loader, pt sup and full time lie and conspire to not tell the truth(I really didn't expect them to tell what really happened)(especially the part-timer since he threatened me)(for several minutes)(and no, I don't expect his homies to give him up)(and yes, the sups don't like me much as I hold them to pull-times and safety)(I can give more detail, but it's pretty boring)............So, I gathered the two pt sups, ft sup and loader(in the trailer, after cleared to pull)(not the same one that threatened me) and we had a meeting. I pulled out my I phone and showed everyone I was going to record the meeting. It was amazing how cordial and TRUTHFUL and helpful everyone was.......although the ft was only worrying about how much time was being taken by the meeting(I told him we ARE going to discuss a safety concern). As I was about to couple, I heard noise in the rear trailer( I knew they had gone back in)(I could have pulled that trailer)(with the loader in it)(I was cleared to pull it down the road).......but that's not me. This is how people get hurt and killed. The pt sups said it was a mis-communication.......I told them we can't have those type mistakes. I will record every conversation with these folks from here on out. I have been burned by folks lying to cover their ass at UPS. No more.
