There is an estimated time of about 3 to 4 hours of an employee’s day (depending on their job of course) that will be used in dealing with telephone communications at the office. Among the most common uses and purposes of calls are for making venue reservations or business arrangements, addressing customer’s concerns, getting hold of suppliers, consulting with managers and even for clarifying points among colleagues across the halls and confirming projects. This basically is the main task of those who works in the call centres – they’re spending their entire shift taking and placing calls.
