The USPS 12 Hour Rule in 2024: An In-Depth Guide

ByCharles Scott Last Update on

The little-known USPS 12 hour rule limits the working hours for postal employees. But it‘s clear that mail carriers, clerks and other staff routinely work far beyond those limits due to under-staffing and excessive mail volumes.

In this extensive guide, I‘ll explain how the 12 hour rule works, who it applies to, exceptions, issues around violations, and most importantly – your rights and options if forced to work overtime.

What Exactly is The USPS 12 Hour Rule?

The formal policy states that except for certain exempt employees or emergencies, USPS staff cannot be made to work:

  • More than 12 hours in a single day
  • More than 60 hours within a USPS defined service week

Importantly, those 12 hours include meal breaks, scheduled breaks and any time spent waiting for mail dispatches or equipment.

So if you have a 30 minute unpaid lunch break and two paid 15 minute breaks, you cannot work more than 11 hours around those breaks.

Here are two example schedules that would violate the 12 hour limit:

  • Start time: 8am, Lunch: 12-12:30pm, Two breaks: 10-10:15am and 2-2:15pm, Finish time: 8:30pm = 12.5 hours
  • Start time: 7am, Lunch: 11:30-12pm, One break: 9-9:15am, Finish time: 7:15pm = 12.25 hours

And two example shift that would be within limits:

  • Start time: 8:30am, Lunch: 12-12:30pm, Break: 10-10:15am, Finish: 8pm = 11.75 hours
  • Start time: 7:15am, Lunch: 11:15-11:45am, Break: 9:15-9:30am, Finish: 6:45pm = 11.5 hours

So you can see even 30-60 minutes makes the difference between an acceptable shift and an excessive one.

Which USPS Employees Does The 12 Hour Rule Cover?

The 12 hour rule covers all major staff roles including:

  • City and rural mail carriers
  • Mail handlers
  • Postal clerks
  • Mail processing machine operators
  • Retail counter staff

The only main exceptions are postmasters, postal execs and some administrative/management roles considered exempt.

One partial exception is city carriers on the "Overtime Desired" list. They agree to work over 60 hours per week year-round. However, even ODL carriers cannot work over 12 hours in one stretch without a waiver.

Rural carriers also see expanded hours of up to unlimited overtime during the peak December mailing season.

So almost all staff have a 12 hour cap per day, with overtime provisions between certain groups.

How Often Do USPS Employees Work Over 12 Hours a Day?

While the 12 hour rule aims to prevent excessive hours, it‘s clear from postal employee forums and surveys that violations remain common.

For example, a 2022 survey by the National Association of Letter Carriers (NALC) union found:

  • 61% of city carriers worked over 12 hours at least once a week
  • 18% of city carriers exceed 12 hours every day

Meanwhile the American Postal Workers Union (APWU) reports carriers in some districts average up to 15 hours during December.

So despite the official policy, 10+ hour days are relatively normal for many carriers, clerks, handlers and drivers.

This leads to immense fatigue and impacts safety.

Why Does The USPS Have a 12 Hour Limit To Begin With?

The Postal Service first introduced national 12 hour restrictions in the 1950s and 60s.

Prior to that, 16+ hour shifts were common as the organization struggled with a massive influx of mail and packages after World War 2 while being deliberately understaffed by Congressional budget cuts.

The extreme hours led to exhaustion, high turnover and raised safety risks.

So the USPS codified daily and weekly overtime limits that became known as the "12 hour rule".

The goal was to strike a balance between operational flexibility and humane working conditions to attract and retain talent.

Over subsequent decades, postal unions enshrined those hourly restrictions into national labor contracts. Although as we‘ve seen, violations still happen in practice.

Exceptions Where The 12 Hour Rule Does NOT Apply

There are some key exceptions where USPS employees can be made to exceed daily or weekly time restrictions:

City Carriers Opting for Overtime (ODL)

As mentioned, city mail carriers can sign up for the overtime desired list (ODL). This allows managers to assign them over 60 hours of work per week without restrictions.

However, even ODL carriers should not work over 12 hours per day without a written waiver.

December Peak Season

Rural carriers have no weekly overtime restrictions for the full month of December. This peak delivery month is excluded from hourly limits thanks to union negotiations.

Emergency Situations

The Postmaster General or district managers can declare an "emergency" to override standard limits. But labor groups argue emergencies are declared too loosely.

In practice, short-staffing, high mail volume, truck breakdowns and even weather delays can be cited as emergencies to compel overtime.

The declaration of these constant "emergencies" to skirt the contracts leads to widespread fatigue and health issues.

Your Rights and Options Around Excessive Overtime

Ensure you fully understand your rights around unlawful overtime based on your role and contract.

If forced to work over 12 hours, you legitimately have two options:

1. Refuse and take administrative leave

Once you hit the 12 hour mark, clock out and go home. You cannot be disciplined for this as long as you have not signed a waiver.

You will still be paid for the remaining scheduled hours in your shift.

However, some employees have reported retaliation threats from individual managers. So understand your risks.

2. Work the overtime then file a grievance

If explicitly instructed to work beyond 12 hours, then continue working but file a formal complaint with your union after.

Document evidence like photos of your timesheets, supervisor‘s instructions and any retaliation.

The union can fight for penalty pay rates and disciplinary action if contracts were violated maliciously.

I recommend you speak to your local union representative to understand the best path forward when faced with unlawful overtime.

I hope you now better understand the USPS 12 hour rule – both how it‘s meant to work officially and how it plays out practically given constant under-staffing issues.
