It would be a nice change of atmosphere to switch from the preload (am shift) to the local sort (pm shift). However the main reason I'm considering this is because I may be without a car for an extended period of time, and I would prefer not asking for rides. The problem is that the train/bus schedules don't look like they run early enough for the preload, earliest being around 5:30 am. There is plenty of trains/buses running around the local sort shift though. I need to get more details on what this switch would involve though. I'm not concerned about if the shift is harder or easier, or the general atmosphere. What I need to know is details like pay, and seniority and stuff like that. Would I keep the same pay? Would I still keep my years worked towards retirement? Does UPS allow switching back and forth between the 2 shifts? Basically any negatives/positives you can think of about making this switch please share (other then the physical or mental aspects of the shift of course).
