Which manual outlines the personnel policies and regulations governing employment within the Postal Service?

The Employee Labor Relations Manual (ELM) is the correct answer because it serves as the primary document that outlines the personnel policies and regulations regarding employment within the Postal Service. The ELM provides comprehensive guidelines on various aspects of labor relations, including employee rights, benefits, disciplinary procedures, and grievance processes. This manual is essential for both employees and management to ensure a clear understanding of the rules governing employment and to maintain consistent and fair practices across the organization.

The other options, while related to postal employment, do not specifically serve the same purpose as the ELM. The Employee Handbook may offer some general information about benefits and workplace practices, but it lacks the comprehensive detail on labor relations found in the ELM. The Postal Operations Manual focuses more on procedures and regulations pertaining to postal operations rather than personnel policies. The Postal Employee Guide might provide useful information for employees, but it does not contain the same depth of regulatory detail concerning employment policies as the ELM does.
