“At a time when the U.S. Postal Service is considering deep cuts in services and jobs, an internal watchdog told Sen. Bernie Sanders on Monday that a big funding cushion already has been built into the mail service’s retirement and health benefit funds. Billions of dollars owed to the funds have been cited by Postal Service managers as a main reason that it must cut 220,000 jobs and close 3,700 post offices and 252 mail processing plants – half of all the current sorting centers.”
