Must every mobile employee in my company carry a >The G-Trac GPS Tracker device?
No. The G-Trac GPS Tracker is designed to be used at individual post locations. For example, if a specific post is staffed with a worker 24 hours a day/seven days a week, then that post would be equipped with a single G-Trac GPS Tracker to be used by all of the employees working at that location. The device is simply passed from person to person as the shifts change.
