Policy on Internet and Mobile Phone Usage
First of all, you need to have a policy on the usage of the internet and mobile phones. Circulate it across the organization and even display it on the notice boards. It is better to identify the requirements and disconnect the internet facility for those who do not need it. You can also cancel the facility of using CDs and pen drives.
Mobile Phone Usage
As far as mobile phones are concerned, communicate with all employees who have company mobile phones to restrict their usage to business purposes. Personal calls will be charged, or alternatively, ask them to use their personal mobiles. If mobiles are used for company purposes, reimburse the amounts upon submission of related bills or data.
Implementation Steps
Since you have already taken necessary steps in withdrawing the same, it should not affect the business. Call for a meeting with all Heads of Departments, involve them in decision-making, gather their inputs, circulate the meeting minutes, submit them to Senior Management, obtain their approval, and initiate the process.
