I spend 80 days a year on the road, often a full week or longer at a time. My senior staff may spend 40 days a year on the road with similar distributions. We typically plan to be out of the office at different times as we are spread thin and are trying to cover all bases. Add vacations, the coming holidays, the stuff of life, and my senior staff and I are together in the office only about half the weeks of the year
I have not done phone 03's and I am pretty certain that my staff would view that as over-the-top intrusion. They are just getting used to the idea that meeting regularly with the boss is a good thing. Also, international calls when I am overseas are logistically problematic.
I am open to suggestions about how to keep connected while on the road.
