Technological developments have enabled a dramatic expansion and also an evolution of telework, broadly defined as using ICTs to perform work from outside of an employer's premises. This volume offers a new conceptual framework explaining the evolution of telework over four decades. It reviews national experiences from Argentina, Brazil, India, Japan, the United States, and ten EU countries regarding the development of telework, its various forms and effects. It also analyses large-scale surveys and company case studies regarding the incidence of telework and its effects on working time, work-life balance, occupational health and well-being, and individual and organizational performance.
