The United States Postal Service announced on Friday it will be offering $15,000 buyouts to 45,000 staff in an attempt to lower operating costs. During a time when 60 percent of Americans pay their bills online, the postal service plans to cut 229 mail centers in total to save $2.1 billion annually. Starting this summer, it will begin by closing 48. Mail handlers must agree to retire by the end of August to be eligible for the payouts. “The agreement with the Postal Service is intended to provide a financial cushion, and added peace of mind, for mail handlers who might be prepared to move on to the next chapter of their lives by leaving the Postal Service,” the National Postal Mail Handlers Union posted on its website.
