Is there any difference between HR Officer and Supervising Officer?

Specific differences are described by the generic scope of each supervisory and managerial level. Another way to look at it is that a manager is responsible for making significant decisions on what the unit does: its purpose, functions and role, and for making commitments and decisions that require the expenditure of significant unit resources. Managers have a significant, external focus (to the world outside the unit), whereas a supervisor has a more internal focused responsibility for implementing the manager’s decisions through the work of subordinate employees. Once a decision is made on what to do, supervisors have a significant role in deciding how to do it; how to achieve the objective established by the manager. Supervisors often perform the same kind of work that the subordinates do; managers do not do the daily work of the unit as a regular part of their work, they may do it more on an exception basis or in resolving the most difficult problems facing the unit.
