Why must Mail Clerks be familiar with postal regulations?

Understanding postal regulations is crucial for Mail Clerks primarily to ensure compliance with legal requirements and to avoid penalties. Postal regulations dictate how mail should be handled, including specific guidelines on acceptable packages, prohibited items, and proper mailing procedures. Non-compliance can result in fines, legal issues, or operational disruptions. By adhering to these regulations, Mail Clerks help maintain the integrity of postal services and ensure smooth operations, which is essential for the overall effectiveness of mail distribution. This knowledge not only protects the clerk and their organization from potential repercussions but also contributes to the reliability of the postal system as a whole.
