Last month, the United States Postal Service announced their plan to move the current six day delivery system to five days by cutting Saturday delivery.
Postal workers gathered across the nation and here in Rapid City today, to express how they feel about the potential change.
"It's gunna hurt jobs and it's gunna hurt the mail in America," said mail carrier Bob Nix. "I don't think we should do it."
Those in opposition are trying to make sure that does not happen by protesting in front of local post offices.
Postal workers say the planned cut would add to an already busy Monday for mail carriers, who drive long routes delivering Sunday's mail.
"What customer wants their mail at seven, eight O' clock at night?" said Branch Secretary for the National Association for Letter Carriers, Rick Hatzenbuhler "Most people are ready going to bed at that time."
Mail carriers say small businesses that could miss out on weekend mail may face hardships because they rely on it.
"We need to take care of everybody," said Nix. "Big business, small business, we're the nation."
But the attempted end to Saturday delivery service would also threaten businesses and jobs for many postal employees. According to Hatzenbuhler, anyone affiliated with the U.S. Postal Service could be at risk.
"There is so many other jobs connected to the post office that relies on us," said Hatzenbuhler. "People that prepare mail and get it to us, there is a lot of people that are tied to the post office."
The post office would remain open on Saturdays if by August 5th delivery is cut; however, express mail, packages, and medicine would continue to ship.
The United States Postmaster says the cut will help the post office save $2 billion annually.
