Postmaster General Louis DeJoy has managed to break the 250-year-old postal service and must resign, according to the Bay State’s junior senator and other local officials.

U.S. Sen. Ed Markey, on Wednesday, joined by Boston City Council President Ruthzee Louijeune, City Councilor Sharon Durkan, and representatives of the American Postal Workers Union, said that postal service to parts of Boston has become so bad, that some residents no longer receive the reliable service that is their right.

“I am constantly hearing reports from residents of egregiously delayed mail delivery, closed post office locations, weeks of lost mail, and so much more,” Markey said. “Specifically, I’m hearing from residents across the city of Boston who are getting mail once a week, if not once a month. They are experiencing months of mail delays, and important mail pieces like medications and checks are delayed on a consistent basis.”

Standing outside the Mission Hill Post Office, Markey also called for the postal service to stop any changes that will result in job losses or further degrade mail delivery performance, “including consolidation of the Brockton Processing and Delivery Center” and “zipcode level data” from the postal service in order to figure out exactly where service lapses have occurred.

Markey is also “supporting efforts in Congress” to hold DeJoy and future USPS leaders accountable to lawmakers. Wednesday’s call for DeJoy to step down was not Markey’s first, and the Trump-era appointee has faced criticism almost from the start.

Scott Hoffman, speaking on behalf of the American Postal Workers Union, said that data shared by the USPS under DeJoy which shows few lapses in service doesn’t match the lived reality of many Boston residents.

“They seem to want the communities to not believe their own eyes and ears,” he said.

Of the data, he said that “if their mouths are moving, they are lying.”

On top of that, if somebody doesn’t do something to stop the problem from growing worse, the postal service may well cease to exist, Hoffman said.

“This is one of those things that people won’t realize they have until it’s gone,” he said.

The plan, according to the union leader, is to make the service so bad that privatization of the program seems a more reasonable response than fixing any problem.

“What you see right now, is somebody who is breaking down the infrastructure. I think it’s a move toward privatization,” Hoffman said.

Louijeune said that residents who aren’t receiving mail are “sick and tired” of not getting the service they deserve.

“We’ve started hearing about this, really, around the city,” she said. “It’s about the entire city of Boston.”

“Justice depends on us keeping our foot on the gas and making sure residents get what they deserve. If DeJoy can’t do the job, he’s got to go,” she said.

Also on Wednesday, Markey, U.S. Sen. Elizabeth Warren and the rest of the state’s congressional delegation sent letters to USPS Inspector General Tammy Hull and DeJoy, demanding the postal service address delivery concerns in Massachusetts.

“For more than a year, we have observed a pattern of facility closures, consolidations, and slowed service resulting in delayed or lost mail for our constituents. Our efforts to address these concerns with USPS have been shrugged off by management. We write to ask that you conduct a review of the cause of these problems,” they wrote to Hull.

They adopted a slightly different tone when writing to DeJoy.

“Proper postal service takes differing lived experiences into account when ensuring that mail delivery is regular and frequent. We understand that proper mail delivery is a justice issue; we question whether you do,” they wrote.

According to the lawmakers, their letters come in response to the failure of the postal service to deliver mail on a timely basis, their refusal to explain the lapse in service to the Boston City Council, and local postal officials’ failure to respond to a Council subpoena.

The USPS did not return a request for comment by press time.
