The sense of lengthening hours, if unjustified by literal clock measure, may nevertheless catch something about the intensity of the work experience in an age that is mastering efficiency. In so many industries people are working faster. Journalists, lawyers, movie-makers, television producers, building contractors-these workers have no visible assembly lines, but their invisible assembly lines are accelerating. The gears and the passing belt are driven by faxes and E-mail messages-time-saving forms of communication. Without the snail's pace of ordinary mail serving as friction, their projects slide forward in a rush. Also driving the work is the expectation of its quickening, plugged-in consumers. You do demand timeliness in your news and your movies and your legal work, don't you? Some jobs fill the seconds and minutes of every hour with the increasing density of transistors on a silicon wafer.
