How the members of your team communicate with each other is changing. 

There is a new wave of instant messaging applications that is in the process of changing how the members of your team communicate with each other.  This change may be causing the older members of your team to scramble  in order to keep up. 

As a manager, you are going to have to take steps  to use your manager skills to make sure that everyone on your team can  stay ahead of the changes that are being caused by instant messaging.
