A supervisor in the context of HR, is an individual who has the authority and responsibility to oversee and manage the work of other employees or a team within an organization. They are responsible for providing guidance, assigning tasks, monitoring performance, providing feedback, and ensuring that work is completed effectively and efficiently.

Their role involves setting production goals, assigning tasks to employees, monitoring the workflow, addressing any issues or challenges that arise, and ensuring that production targets are met. The supervisor also plays a key role in employee development, providing training, coaching, and feedback to help employees improve their skills and performance.
