Two Philadelphia-area U.S. Postal Service unions plan protests on Thursday over mail-service counters in Staples Inc. stores.
Postal union leaders say the mail-service counters, to be staffed by Staples employees, threaten higher-wage unionized postal jobs and the survival of traditional post offices. More retail chains could seek mail-service counters, they said.
The protests are part of a "national day of action" by the American Postal Workers Union. Rallies are also planned for Pittsburgh and Easton in Pennsylvania, and Brick Township and Hamilton in New Jersey.
Staples, the office-supplies chain, had no comment.
Postmaster General Patrick Donahoe has said the Staples partnership won't result in job losses at the nation's 33,000 post offices. He said the deal is "all about growing our business."
