Not likely an error, but can't rule that out just yet.
Also, you haven't said where your device is being triggered, but you may be entering an area designated to alert you by location. Restricted cell phone area [your profile shows you in an auditorium where a geofence could likely be set up], or somewhere your employer wishes to track your activity? Lots of possibilities. Is your device work issued, or did you buy it on the street used or new?
All just guess work until we know more about your circumstances.
