The investigation into the issue of workplace safety of temporary workers emerged as a joint investigation between ProPublica and Univision News' investigative unit. Univision's investigative unit then continued investigating and exposed different cases of injured temp workers, including the death of a temp worker in a sugar plant. Blue-collar temp work is the fastest-growing and more dangerous segment of the U.S. labor market. Since the 2008 recession, companies have increasingly turned to temporary employees to work in factories and warehouses and on construction sites. In some states, temp workers are six times as likely to be injured than permanent employees doing similar jobs.
