Question

Is there a cheap way to block my employees from receiving calls on their cellphones during working hrs?
Receiving calls on personal cellphones while in the factory leads to loss in production. I want to control that. How to do it?

Answer

You cant legally do it without their consent unless you make a company policy requiring that all cell phones are prohibited and if anyone is found using one then they will be warned and then eventually let go. They have to sign this consent paper or leave and not be employed there any longer. brIf they are concerned with receiving emergency calls tell them to leave your office number, or a secretarys office number with family to contact them via the service so if its important enough someone can get through to them, otherwise all other calls are unnecessary and a great distraction, etc.brbrI would even hold a meeting discussing this they shouldnt be allowed to discuss it or theyd argue with you. You tell them the rules and thats it.
