Behind the Scenes of the Supply Chain

Before the mail ever reaches a delivery truck, it must be processed at lightning speed in our massive sorting facilities. The Mail Handler Assistant (MHA) is the physically demanding, high-energy engine of the USPS processing plant.

  • The Work: You will load, unload, and move bulk mail and empty equipment. You will physically toss sacks, push heavy wire cages, and operate mechanized sorting equipment.
  • The Environment: Fast-paced, loud, and industrial. This is not a desk job; it is a full-body workout.
  • The Future: MHAs are first in line to become Career Mail Handlers, unlocking federal pensions and lifelong healthcare security.
