There are 1.27 million lawyers in the United States, one for about every 300 Americans — about 400,000 more of them than there are doctors. Their work is rarely glamorous, and especially for those just starting out in the profession, it can be grinding and repetitive. Jason Luckasevic, hired out of law school in 2000 by a firm in Pittsburgh, passed the bar exam on his first try and was quickly sworn in to practice. The ceremony, such as it was, took place on a Thursday in a clerk’s office, rather than in a courtroom in front of family and friends, because his bosses needed him to get started. The following Monday morning, he drove to Johnstown, about 90 minutes away, where he spent the day taking depositions from former employees of an enormous steel plant that had exposed them to asbestos. Late that afternoon, he climbed back into his Honda Civic and headed home. He repeated this routine for the next six months, five days a week, racking up some 400 depositions and about 20,000 miles on the road.
