The Postal Service is facing a deficit of $238 billion over the next 10 years, The Los Angeles Times reported Monday.
"Given the fact that we're facing such a huge deficit, we'd like to move as quickly as possible," Postmaster General John Potter said at a news conference.
To move forward, the proposal next goes to the Postal Regulatory Commission for approval.
If approved, the plan could save $3 billion in operating costs in the first year and $5.1 billion per year after that through 2020, the Postal Service said.
The cuts would include 26,000 carrier positions that the Postal Service said would be handled through attrition and 13,000 part-time substitutes, who often work just one day a week, the Times said.
