Telecommuting is a natural for the business traveler. Every time we head out on a trip we become default telecommuters. So if you're new to the whole idea of working out of the office, or from the hotel/plane/train/car, you might want to read these Telecommuting articles at Melissa Dylan's Working Culture topic at Suite101.
This article, her Adjustment Period telecommuter piece, is useful and applicable for the business traveler. You might be dealing with issues of checking in with the boss, dealing with co-worker jealousy and handling time-stealing family requests (especially if the family is along for the business trip).
Each time you see the words home in these articles, mentally insert coffeeshop, airport, hotel room, yurt, igloo or wherever else you are temporarily and professionally squatting.
