_____________ is a continuous process because new jobs may be created and some of the existing employees may leave the organisation.

The correct option is Staffing.

Explanation:
Staffing is the managerial function of acquiring, deploying, and retaining a workforce of sufficient quantity and quality to create positive impacts on the organization's effectiveness. It is considered a continuous process due to the following reasons:
1. Dynamic Nature of Business: Organizations continuously evolve. As they grow or diversify, new jobs and roles are constantly created, which requires hiring new personnel.
2. Employee Turnover: Employees regularly leave organizations due to retirement, resignation, promotion, transfer, or termination. These vacancies must be filled promptly to prevent disruptions in workflow.
3. Ongoing Development: Staffing also involves training, development, and performance appraisal, which are ongoing activities to keep the workforce aligned with organizational needs.

Thus, staffing is not a one-time event but a permanent, ongoing process that runs throughout the lifespan of any organization.
