Having a smartphone might seem a casual thing, but many don't realize is that presence of smartphones has opened a portal of hell - not literally, its just that people target smartphones to carry on their illicit activities such as bugging, cyber bulling, cyber crimes, and most importantly they can easily cheat people. As for such kind of scams and frauds, children and employees are the easy targets!
Kids Will Be Kids - You Act Mature
Kids, especially teens will act weird, will rebel and revoke almost any rule you put up on them. Remembering back one's own teenage days can justify these facts, but still, those justifications don't give a pass to your kids to carry on with their activities. You have all rights to monitor them regularly. Teens do almost ever forbidden things, because their's is an age of curiosity and anxiousness.
It's up to the parents how they want to tackle these issues and keep a check on their kids!
Employees Could Be Disastrous
Well, it varies from person to person; it could either be a single employee or a group of employees who could turn up against you and worst case scenario could be - your company's confidential information getting leaked out. If you have had a similar experience before hand, then it is suggested to monitor all activities of your employees. This will help you save your company and know who is a loyal employee!
Just to stay ahead and monitor your employees or kids, its better to install a cell phone tracking software in their cell phone and keep things in your hand. Always act first before things happen!
