This employee monitoring by the warehouse company seems to be a bit excessive. I could see this happening if there is a particular employee that spent a little too much time in the bathrooms, tardy from lunch, or tardy coming, in as this would be a sign of something wrong. I had an employee that had some issues with this and just as we suspected he was a drug user. His numerous breaks weren't due to stomach issues but instead to shoot up his drug du jour. After some confrontation, we were able to get him into a drug rehab center and whatever came of him I don't know.
As far as vehicle monitoring goes, this is a great idea. I've seen too many truck drivers texting and using their cell phones more often than the rest of the drivers. Considering the size of their vehicles and the loads they are carrying, this does present a safety issue.
