The U.S. Postal Service could look a lot more like a private corporation in a few years.

The current postmaster general, Megan Brennan , plans to step down from her position in early 2020 after a career in the Postal Service and five years as the first woman to head it. The agencys board of governors, which is now stocked with a quorum of Senate-approved Trump nominees, will name her successor.

Like other close watchers of the agency, Ronnie Stutts, president of the National Rural Letter Carriers Association, suspects the board will look outside the Postal Service for its next leader, perhaps to someone in the business world. Stutts biggest fear is that it will choose someone eager to spin pieces of the service off to the private sector.

After all, as Fortune recently reported, thats what the White House has recommended to turn the independent federal agency into an investor-owned utility .

Theres a real risk that the successor could try to hand over parts to privatize. Thats what we dont want to happen, Stutts, a former letter carrier whose union represents 130,000 postal employees in rural and suburban areas, told HuffPost. We welcome innovation; we just dont want privatization.
