Final answer:
The management function related to the founder speaking to the employees about their work in finding a cure for pediatric diabetes is leading.
Step-by-step explanation:
When the founder of an organization addresses all the employees, emphasizing the importance of their work in finding a cure for pediatric diabetes and urging them to continue their efforts for the children, it can be associated with the management function of leading. Leading involves inspiring and motivating employees, as well as influencing their behavior through communication, group dynamics, leadership styles, and other interpersonal processes. Unlike planning, organizing, and controlling, leading focuses on guiding and encouraging team members towards achieving the organization's goals.
