United States Postal Service The United States Postal Service employs some 617,000 workers, making it the third-largest civilian employer in the United States behind the federal government and Wal-Mart.[39] In a 2006 U.S. Supreme Court decision, the Court noted: "Each day, according to the Government's submissions here, the United States Postal Service delivers some 660 million pieces of mail to as many as 142 million delivery points."[40] As of 2016, the USPS operates 31,585 post offices and locations in the U.S., and delivers 153.4 billion pieces of mail annually.[2]
Going postal The expression derives from a series of incidents from 1986 onward in which United States Postal Service (USPS) workers shot and killed managers, fellow workers, and members of the police or general public in acts of mass murder. Between 1970 and 1997, more than 40 people were killed by current or former employees in at least 20 incidents of workplace rage.
