The Red Book (Handbook M-41)
What carriers call Handbook M-41 — the rulebook for how the job actually gets done.
📕 What Is the Red Book?
"The Red Book" is the nickname carriers use for USPS Handbook M-41, City Delivery Carriers Duties and Responsibilities — named for its red cover. It's the Postal Service's official manual for how city delivery work is supposed to be performed, from casing mail to street delivery to safe driving.
Where the National Agreement (the NALC-USPS contract) covers your rights, the Red Book covers your duties — the procedures management expects you to follow. Knowing both is how you protect yourself: the Red Book tells you what's actually required, so you can push back when a supervisor asks for something it doesn't say.
🗂️ What's Inside
- Office duties — casing, pulling down, preparing mail for the street in delivery order.
- Street duties — delivery methods, sequencing, handling parcels and accountable mail, customer contact.
- Vehicle operation — safe driving practices, parking, and load securement for postal vehicles.
- Safety — the baseline safety practices carriers are expected to follow on the route.
- Conduct — professional standards for interacting with customers and the public.
⏱️ Why It Matters for CCAs
New carriers often hear "that's not how we do it here" from a supervisor or a veteran carrier. Local habits and shortcuts exist everywhere — but the Red Book is the actual standard. When there's a dispute about whether something is "the rule" or just "how it's always been done," the Red Book is one of the first places to check.
If a supervisor tells you to do something that doesn't match what you've read in the Red Book, that's worth a conversation with your shop steward — not necessarily a confrontation on the spot.
🧭 How to Use It on the Job
You don't need to memorize it. Most carriers keep it as a reference for the handful of situations that come up again and again: how a delivery point should be sequenced, what counts as an accountable item, or what the manual actually says about a disputed procedure. Your station should have a copy available, and your shop steward can help you find the section you need.
