Complaints against a U.S. Postal Service (USPS) employee are easily filed online at the USPS website. If your business is experiencing a delivery issue or has a concern regarding customer service, the email service or a telephone call offer a convenient way to discuss the problem. For more serious concerns, such as potential theft or fraud, the USPS Office of the Inspector General takes the lead. The inspection service can also be contacted online.

Talk to Your Carrier

Postal routes are handled by a regular carrier most days of the week and a substitute for some Saturdays and to cover the regular carrier's vacation days. If you have a complaint that leans more toward a request, such as that mail be left at a different location within your business, flag the carrier the next time she stops by and explain your request. As long it does not interfere with the execution of duties or violate postal code, the carrier may be able to accommodate you. A regular carrier can also discuss delivery issues with her substitute, so feel free to reach out to your normal carrier if your Saturday delivery schedule is a problem. For more serious problems, take your complaint to the next level.

Online Complaints

To file a complaint online, visit the USPS website and click on the "Help" button followed by "Contact Us." Click "Customer Service" followed by "Email Your Question." For concerns about employees, select the "Personnel" tab and select the employee type, such as letter carrier, clerk or supervisor and "Continue." In the provided form, add details about the employee and the situation. Blanks allow you to list the date of an incident and details about the situation. Add the contact information for your business on the next page. All of your entries are presented for review on the final screen before submitting. If you see an error, you can edit the form. Otherwise, submit and wait for a return email. These communications are forwarded to a supervisor at your local post office for review and response.

Contact the Local Post Office

Reaching out to your local post office is an excellent way to touch base with a direct supervisor. At some post offices, the postmaster directly supervises both carriers and the front counter. Larger units sometimes have a delivery supervisor who then reports to the postmaster. When you call the local unit, tell the employee who answers the phone that you want to speak to a supervisor regarding a carrier complaint. This will ensure you are connected to the appropriate person.

Explain your complaint clearly and how the problem impacts your business. The supervisor will then discuss the problem with the carrier and find a solution. If the problem persists, call the office back and let the supervisor know. Having trouble finding the right phone number? Call 1-800-275-8777 to get contact details for the post office that services your business.

Criminal Complaints

More serious concerns, such as theft or fraud, should be escalated above the local post office. Two agencies oversee the post office for criminal issues, such as the theft of mail by carriers, employees or contractors. The USPS Office of the Inspector General investigates allegations of fraud, waste and misconduct. Complaints can be submitted by both employees of the USPS and consumers. To file a report, visit OIG website and click on "Contact Us." Select the appropriate complaint under the "I Need to Report" section.
