Same with us. Our area for storing boxes will hold about 4-5 small boxes and 1-3 large boxes from each route at any one time.Where in the world do you have the office space to store all of the oversized/heavy parcels? Our office is crammed full and then some. The stuff HAS to leave the building the day it comes in because the next day will always be the same or worse as far as parcels.
We have filled a pumpkin and stashed it in a hole by the dock at for a day or two, but space is a premium. More stress about getting rid of the big stuff each day. As a part timer sub, I've probably had 10 3-trip days in the last 6 months. Never got a word back about it.
