Thanks Dr Brownz but I did read ALL the threads and it still made no sense, but hey who am I to question a question.
Management in his building decided to add another person to the preload "crew", which is not exactly a formal designation but its a past practice that exists in many buildings. Before my center had preload we had the local sort crew and the 2 person pt crew that worked mornings to help the drivers sort and load. It was always a pain in the ass to cover a pter call in in the morning so my center did a similar thing, added a 3rd pt in the morning crew(they really only needed 2 to unload trailers). Sometimes the third guy is bumped by air drivers who get the air from the airport.
But actually there is one unanswered question: Was OP the one who was calling in? And now is this retaliation for calling in?
