Although work has been around as long as humanity, the study of working is barely a hundred years old. And 'working', that is, the human being at work, has so far been given little systematic attention. Yet we know that work and working are different. Work is a 'something', an object - and as such outside ourselves and in need of systematic analysis and synthesis. 'Working' is a human activity, and as such endowed with personality, with distinct physiological, psychological and social needs and characteristics. And working has economic as well as power dimensions. Yet work and working have always to be together and have to be managed together.
