The USPS Inspector General claims the postal service could save as much as $2.3 billion a year by using part time employees to case and prepare mail for city letter carriers. The OIG arrived at this conclusion after comparing USPS work methods with those of FedEx and UPS.
Postal service management disagreed with the recommendation, pointing out that it was not possible under current collective bargaining agreements. The USPS did say that it is
currently working with NALC to examine how city delivery routes might be structured in the future. The parties are working on a test that will attempt to separate the casing and delivery functions to the extent possible while operating within the current work rules…
Management also indicated in a separate discussion that the Postal Service will pursue additional flexibility in the workforce and provided a target date of May 2012 for their ongoing test to separate the casing and delivery functions.
