You may think you have no way of knowing what your employees are doing with their time unless you physically pay a visit to the job site, but thanks to the expanding world of GPS-based fleet vehicle management, this is not necessarily the case.
If you were the boss of any sort of non-roofing-related company like, say, the software-engineering firm in the movie Office Space, then you would be able to closely monitor your employees. You could see when they arrived, tell when they took extended coffee breaks and even track their Internet usage if you wanted to. Of course, we are sure you would be a better boss than the guy in the movie, who had some employees that ended up stealing from him and another who burned down his building.
At any rate, the point is: You may think you have no way of knowing what your employees are doing with their time unless you physically pay a visit to the job site, but thanks to the expanding world of GPS-based fleet vehicle management, this is not necessarily the case.
