Because work involves producing things, it takes place within fixed boundaries. Not only is it tied to a specific neighborhood, employer, or industrial quarter, it is time-bound and regulated by hours and weeks. Careers, by contrast, tend to be loosened from the constraints of space and time. People who have careers are prepared to move anywhere in search of the next stage, either within the firm or within the country. They are not, however, prepared to punch a clock. Process, not output, counts as the measure of success. Those who pursue careers manage rather than produce. Indeed, one of the things they devote a great deal of time to managing is the transition to an economy that produces less.
