What does GPS technology primarily track regarding supervision?

GPS technology primarily focuses on tracking the whereabouts of individuals. This capability allows supervisors to monitor the locations of employees in real time, ensuring that they are where they are expected to be for their assigned duties.

While it may seem like tracking employee performance, GPS is not designed to evaluate how well an employee is performing their specific tasks or activities in detail; its primary function is related to geographical positioning. This means that the technology can provide valuable information regarding an employee's movements, but it does not provide insights into the quality of their work, their engagement level, or their communication with others.

The options that imply broader monitoring, such as tracking all activities or communication, extend beyond the core function of GPS. The technology does not intrinsically capture performance metrics or communication without additional systems in place. Hence, employee whereabouts is the most accurate and focused interpretation of what GPS technology primarily tracks in the context of supervision.
