Traveling Causes a Hit in Business Productivity?

As a small business with a significant number of employees who travel extensively, these numbers from the Australian Sunday Herald came as a bit of a shock:

Recent research shows more than half of Australian businesses (55.3 per cent) believe that merely having the cost of roaming in mind when travelling impacts employee productivity. For small-to-medium sized companies, this was more relevant when compared to larger organisations (62.2 per cent versus 49.0 per cent).

But it goes one step further. The research indicates nearly half (49.6 per cent) of employees are unlikely to call or text colleagues who are travelling internationally due to the high costs and complexity of roaming. So not only do we limit our own communication when we travel, our colleagues back home are less likely to communicate with us.

Perhaps there is something to limiting phone calls, but there are factors like time zones in play as well.  But limiting texting?  Thought-provoking.
