Resigning from the postal service is different than leaving most jobs. You're part of a federal system with clear hierarchies, union protections, and personnel files that follow you. Whether you're a carrier, clerk, mail handler, or supervisor, your resignation letter becomes part of your permanent record—and how you leave can affect re-employment eligibility and references down the line.

The reason you're leaving shapes what you write. A better-paying logistics role needs a different tone than walking away from chronic understaffing or pivoting to a completely new field.

Why your reason for leaving shapes the letter

Postal Worker resignations land in your official personnel file and may be reviewed if you ever apply to federal positions again. A vague letter works fine, but tailoring your message to your actual situation—better offer, burnout, relocation, career change—makes handover smoother and keeps professional bridges intact. If you're leaving on good terms for a clear opportunity, say so. If you're burned out or dealing with workplace conflict, keep it professional and brief. The examples below cover the three most common scenarios.

Thank you for the opportunity to serve. I have great respect for the work this team does.

Industry handover notes for Postal Workers

  • Route documentation: Leave notes on delivery quirks, dog warnings, access codes, business holds, and customers who require special handling
  • Accountable mail: Ensure all scans are complete, no undelivered certified or registered items remain, and your accountable log is current
  • Vehicle condition: Complete a final vehicle inspection form, note any damage or mechanical issues, and return keys/fuel cards to supervisor
  • Case and equipment: Return scanners, satchels, arrow keys, uniforms (if issued), and any other USPS property; document serial numbers if required
  • Leave balances and benefits: Confirm your final paycheck schedule, submit any pending leave requests, and understand TSP rollover or FEHB continuation options if applicable

What to do BEFORE you submit the letter

Resigning from a federal job has consequences you can't undo once the letter is in. Before you hit send or hand over the paper, lock in the basics. If you're leaving for another role, confirm your offer in writing—start date, salary, benefits. Screenshot or save the offer email. If you're walking away without something lined up, make sure you have a financial cushion; USPS jobs come with health insurance and TSP matching that stop the day you leave.

Check your leave balances. Some employees are owed annual leave payout; others lose it depending on employment type (career vs. non-career). Talk to a union steward or HR before you resign if you're unsure. Know your re-employment eligibility window if you think you might come back—USPS does rehire former employees, but personnel file notes matter.

Finally, decide whether you're telling your supervisor verbally first or submitting cold. In postal culture, a quick heads-up conversation before the written letter often smooths things over, especially if you've been reliable. If the relationship is strained, the letter alone is fine. Just keep a timestamped copy—email with read receipt, or a photo of the signed paper you handed in.
