Delivering for America Act This bill prohibits the U.S. Postal Service (USPS) from making changes to operations or levels of service from those that were in effect on January 1, 2020. Specifically, the USPS may not, during the period beginning on enactment of this bill and ending on the last day of the COVID-19 (i.e., coronavirus disease 2019) public health emergency or January 1, 2021, whichever is later, implement or approve any change to the operations or the level of service that would impede prompt, reliable, and efficient services, including changes in the nature of services that will generally affect service on a nationwide basis; revisions of service standards; closures or consolidations of post offices or reduction of operating hours; prohibitions on payment of overtime pay to USPS officers or employees; changes that would prevent the USPS from meeting its service standards or that would reduce measurements of performance concerning those standards; changes that would have the effect of delaying mail, allowing non-delivery to a delivery route, or increasing the volume of undelivered mail.
