I am a loader at local sort. I'd load about 800 - 1200 packages in the 28 footer by myself in less than two hour time frame. It seems we are getting busier and busier (good thing!) each week and I often get overwhelmed by the volume. I still keep up though. My question is, at what point do they bring in new employees to lessen the load on current employees? Is there reasonable limitation as to how many boxes loader can handle per hour basis?
