Who among us, hand on heart, can say we did not take the odd work-related call during the summer break, or check the occasional work-related e-mail from the comfort of a foreign beach?

Technology, such as wireless networking, BlackBerries, Palms and PDAs, has revolutionised employment, giving most companies sufficient infrastructure to influence how, where and when we work. IDC, the research company, estimates that, by 2009, 25 per cent of the global labour force will work from home or on the move.
