"98 Minutes" is a collaborative multimedia investigation by WBEZ and the Center for Public Integrity. The project examines the death of a temporary worker due to burns he suffered on the job at a Chicago-area factory. It also examines crucial workplace-safety enforcement issues affecting temporary workers, a growing part of the U.S. labor force. Our reporting found that these temp workers face distinct hazards and that the federal government isn't keeping close track of their injuries. Highlights of the investigation include (a) data, acquired and analyzed by WBEZ, that expose the lack of federal record-keeping concerning temp-worker injuries and (b) a U.S. Occupational Health and Safety Administration internal memorandum, acquired by CPI, that recommends criminal prosecution for alleged safety violations found during inspections triggered by the death, (c) recorded comments from top national OSHA officials recorded in ambush-style settings after the agency had failed to grant repeated interview requests and (d) recorded comments from a recently retired top regional OSHA official who suggested a way for the agency to step up inspections of temp-worker job sites. The project, co-reported by WBEZ's Chip Mitchell and CPI's Jim Morris, includes five components: (1) a 12-minute broadcast story, (2) a 3,500-word text story, (3) a timeline with still photos and text enabling web visitors to follow the 98 minutes between the worker's accident and his arrival at an appropriate medical facility, (4) data visualizations showing the growing number of U.S. temporary workers and the lack of federal records about their injuries and (5) a 25-minute conversation about temporary-worker hazards and safety enforcement. The conversation, broadcast live and recorded for web streaming, includes experts and listener callers.
