Both UPS and FedEx are having issues moving all volume they are getting. So a shipper may load a trailer that UPS picks up and UPS does not unload the trailer for days so it still shows label printed but no movement. The issue is usual on ground shipments that move between UPS hubs on trailers. The is just not enough drivers on the long haul loads to move all the trucks.
We are having this issue most with our shipments from our Southern CA warehouse. Example a package our warehouse loaded on a trailer 8/27 was just scanned yesterday at the FedEx So. CA hub. Usual once moving the package will move thru the system as normal.
It is a customer service mess as anyone tracking their package thinks it has not been shipped by our warehouse.
