Instant messaging, also known as IM, has become prevalent at work, and is fast becoming a management and HR issue. In fact, a report issued by Radicati.com, states that in 2011 there were nearly 2.6 billion IM accounts worldwide and that number is expected to grow to over 3.8 billion by the end of 2015.  According to Radicati, that’s a growth rate of 11% per year. IM isn’t necessarily bad or disruptive for businesses IF it’s used correctly and for the right purposes.
