The endorsement follows Sanders’ spirited address to the APWU Las Vegas Conference in October.
“We should judge candidates not by their political party, not by what they say, not by what we think they stand for, but by what they do,” said APWU president Mark Diamondstein. “Applying that criteria, Sen. Bernie Sanders stands above all others as a true champion of postal workers and other workers throughout the country.”
During his tenure in the Senate, Sanders has opposed both the consolidation and closure of USPS mail processing facilities and post offices; opposed privatization of the mail service; and has voted to restore USPS’ overnight delivery service, and continue timely mail delivery in rural areas.
APWU’s endorsement is a critical one for Sanders.
Democratic front-runner Hillary Clinton has already received endorsements from two of the largest labor unions in the U.S., the National Education Association and the American Federation of State, County and Municipal Employees, with approximately 3 million and 1.6 million members respectively.
With Thursday’s announcement, Sanders now has the backing of two labor unions. In August, the National Nurses Union (NNU) announced their support for the Vermont Senator.
NNU has approximately 185,000 members in the United States.
