Today, life has become simpler due to technology. One way to monitor the activation time of the Internet or phone line completed by field staff is to check it against the standard work time. This helps determine whether they are efficient or wasting time. However, a more reliable method is the use of GPS trackers.
Using GPS Trackers for Employee Monitoring
Latitude from Google is one such software. Most of your employees likely have smartphones (my office boy has an Android phone), where Latitude can be activated and used to track the exact location of the person. Employees should be instructed not to switch it off during office hours. Ghost working will also be detected as you can call to check, and if the same voice answers multiple numbers, then you know what is happening.
Some Indian companies have developed personnel tracking GPS devices as stand-alone products. I know three courier companies that use these. Ostensibly, they are provided so that HQ knows where you are and you can be diverted quickly to a customer in emergency service needs. Actually, these are being used to know where the employee is. The tracker is accurate to within a 10 ft radius.
Being a telecom company, you can get free or low-cost connectivity for your GPS trackers. In India, the connectivity cost is as low as Rs 99 per month. The GPS devices cost between Rs 3500 to 9500 depending on what you want. Blue Dart, for example, has combined it with a barcode reader and takes the receiver's signature electronically to confirm and update the delivery status to the sender. That would be costly, but they can afford it. Another local delivery company has opted for a tracker built into a pager-type device that all their field staff carry. That’s at the lowest range.
Of course, the cheapest way is to use an app on a smartphone and track the entire workforce from the office free of cost.
Hope this helps.
