This week, Postmaster General Louis DeJoy pulled back on a host of cost-saving measures at the U.S. Postal Service after a public outcry over delivery delays and the potential to upset mail-in voting come November. Of particular concern was the removal of hundreds of mail sorting machines.

According to a grievance filed by the American Postal Workers Union and obtained by The Washington Post, the USPS was poised to decommission 671 of the massive machines, roughly 10% of its inventory, and capable of sorting 21.4 million pieces of paper mail per hour. The Postal Service, by comparison, processes as much as 500 million items each day.
