Ergonomics For Road Warriors?

madHomer asks: "About three months ago I took at job in a professional services organization. Our standard consulting stints are about one month apiece, so I never really get settled at a work site. Although I enjoy being away from my cubicle 90% of the time, my body is not enjoying the time spent at the client site. It seems like every three days I am shuffled into a new office, server room, conference room or cubicle that have varied chairs and desks. How do the fellow road warriors out there combat sore necks, numb hands, and bad backs from constantly changing conditions on the road? Also, what are some of the regulations out there? Is it my employer's responsibility to make sure that my work area is ergonomic when I am on the road?"
