Who primarily utilizes Postal Service handbooks?

The primary users of Postal Service handbooks are postal employees. These handbooks serve as essential resources, offering comprehensive guidelines, policies, and procedures that govern various aspects of postal operations and employee responsibilities. They provide crucial information on topics such as customer service, mail processing, and safety protocols, which are vital for the efficient functioning of postal employees in their day-to-day activities.

While other groups, such as the general public, investors, and government officials, may have an interest in postal operations, they do not rely on these handbooks for their roles or duties. The content of the handbooks is specifically tailored for the needs of postal staff, ensuring they have the necessary knowledge to perform effectively in their positions. This specificity in purpose underscores why postal employees are the primary users of these handbooks.
