FAQ on Telework and Telecommuting by Telework Unlimited . The emphasis here is on reduction or elimination of the daily commute to and from the workplace.
Telecommuting is a form of teleworking.
Also, in my definition, telecommuters are generally employees of some organization, as contrasted to people with home-based businesses. Again, the distinction is that, absent telecommuting, these people would be going to a work place somewhere else. The term teleworking, on the other hand, includes such variations as home-based businesses that use telecommunications to work with their customers, as well as those who may commute every day to some traditional location but use information technologies to deal mostly with people in other cities, states, or countries. The number of teleworkers in the world is also growing, possibly even at a faster rate than the number of telecommuters. The immense growth of the Internet, assuming that it survives the expansion problems, is a major factor in this.
