Having worked in one of the few centers that have a full time preload, I have both driven and preloaded. I have to say that both jobs have their merits. Some people prefer preloading and some prefer to drive. To me, the grass seems greener on the other side of the fence. When I preloaded, I always got my breaks and lunches on time, overtime was kept to a minimum and I was out of the weather. I felt bad for the drivers. When I drove, I enjoyed working outside, meeting different people and not having a supervisor around constantly. There were plenty of times when I was on preload when I wished that I was driving and vice-versa.
