"We're watching the deliberate destruction of the Post Office unfolding in front of us." The operational changes described by Portland mail carriers resemble a new initiativ e the USPS officially launched Wednesday titled "Expedited to Street/Afternoon Sortation (ESAS)."Under the new program, according to a USPS document posted on Twitter by The Intercept's Ryan Grim, "city carriers will not sort any mail during the morning operation.""They will clock in, retrieve mail that was pulled down from the previous day," the document reads. "Any unsorted First Class flats will go directly to the street with the carrier and be routed in delivery sequence while on the street. Upon return from the street delivery, carriers will sort all mail, as directed by management. During this time they will also handle any ancillary duties previously performed in the morning"
