The building where I am employed received 1734; all Express; and management was to maintain physical control until they were all scanned, processed, etc. Then, we handed them to the driver, watched them walk into their truck, and we "signed off"; at that point, it is on them if some go missing (or on the management person if they were stupid enough to "lose" one).
We didn't actually know the details (amount, addresses, tracking numbers, etc) until about quarter of 8am. It was quite frantic after that.
From my low rung on the corporate ladder, I did my job; however, I feel bad for the drivers and the driver supervisors because there were no manifests, half of them were not in EDD; I mean, how are you supposed to track one of these things? That's above my pay grade, apparently.
It's unfortunate it had to be this way; with proper information and an appropriate lead time, we (i.e. the building I work in as a whole) could have processed them all no problem.
