Final answer:
Reward Systems is not a function of Human Resource Management.
Step-by-step explanation:
The correct answer is Reward Systems. While all the other options listed are functions of Human Resource Management (HRM), reward systems are not considered a core function of HRM. HRM is responsible for tasks such as organizational design, staffing, performance management and appraisal, and employee training and organizational development. Reward systems, on the other hand, fall under the purview of compensation management and are typically handled by the finance or compensation department within an organization.
