Alas, at the heart of private legal practice is perhaps the most autonomy-crushing mechanism imaginable: the billable hour. Most lawyers—and nearly all lawyers in large, prestigious firms—must keep scrupulous track, often in six-minute increments, of their time. If they fail to bill enough hours, their jobs are in jeopardy. As a result, their focus inevitably veers from the output of their work (solving a client’s problem) to its input (piling up as many hours as possible). If the rewards come from time, then time is what firms will get.
