A downside of cheap communication, like the email, is that there is way too much of it.
The sheer volume of e-mail information flow seriously, threatens theirs advantages as knowledge workers suffer from a chronic state of mental overload, reduced productivity and a declining sense of well–being.
E–mail is becoming a tragedy, encouraging casual placement of corporate spam in the in–boxes of all.
Information overload exists for all business communication channels.
Instant messages, system alerts, phone calls, visits from co–workers and even self–interruptions occur so frequently that workers rarely have more than five minutes of focused work before an interruption occurs.
If users take an average of one minute to read and respond to each message, the current volume consumes more than a quarter of an eight–hour day.
With projected growth of incoming messages, workers could spend 50 percent of their workday managing e–mail by 2009. How much of that time is and will productive?
It's true, many of that time has profit value. But how many hasn't?
