A lie detector or a polygraph examination is something that is very popular and has been around for a long time now. Although technology has advanced there is nobody that can fool this test and in case you doubt somebody then one of the best things to do is to ask them to undergo this test so that they can prove their honesty to you. While it is not tough to find talented people in the industry these days it is extremely difficult to find somebody who is loyal towards the organization. No matter how well you treat your employees there is always going to be one person who wants a little more and could sell out your company secrets to another organization for their personal benefit. 
This could prove to be very bad for your organization and if you do not want such employees then you should always ensure that you get your employees tested on a regular basis on the lie detector test. Not only does this ensure that you have employees who will not think about cheating the organization, it also maintains the level of honesty throughout your work force. You need to remember that you need to keep your employees aware about the situation and all higher authority employees should be informed that they need to take this test from time to time especially when it comes to certain decisions in the organization.
