Pat Tourney, who lives in Detroit, said she hasn't worked for the postal service but turned out Thursday to join the protest. Holding a sign that read "SAVE THE USPS," she said that, as a customer, she believes in the post office.

On Thursday, postal workers chanted, “U.S. mail not for sale,” in front of eight Missouri post offices, hoping to make their point to the federal government.

United States are protesting against potential changes to the United States Postal Service (USPS), which they say could result in job losses and service reductions, particularly for rural communities.
