A national rally Monday protesting the moves to privatize the U.S. Postal Service.
Postal Service employees joined with community activists at 140 different sites carrying signs that read "the U.S. mail is not for sale."
In Tucson, a group of about two dozen lined up along Broadway between Swan and Columbus to bring awareness to the potential selling off.
In June, the White House's Office of Management and Budget proposed shift the business of mail carrying to a private entity.
A report on the impacts of that move was due on the president's desk on Aug. 10, but that report has yet to be publicly released.
"We're not waiting to see the task force report. The administration has already indicated where they're headed," American Postal Workers Union President Mark Dimondstein said. "Private companies are going to raid the precious resources of the people's Postal Service, which has only grown more valuable due to the growth of ecommerce. Then these companies are going to raise prices, cut service and leave rural communities isolated, senior citizens stranded and many businesses without a reliable means of reaching their customers."
