The purpose of this study is to investigate the labor environment of IT workers in connection with the introduction of the 52-hour work per week in the domestic IT industry. The survey was conducted between June and August 2019 on 1,364 IT workers, including basic working conditions, such as working hours, breaks and welfare systems, and health and safety education. As a result of the study, the welfare system was well provided for workplaces with 500 workers, including securing exercise space, and occupational safety and health education were well conducted. 70.16 percent answered that the average working hours per week were between 8 and 10 hours per day, and there were some differences between the size of workplaces and jobs. The daily working hours were the highest for SI jobs, the lowest for management, and the H/W maintenance staff during rest hours, while the digital content workers did not have adequate rest time. In addition, it did not believe that the perception of labor unions by IT workers could actively help solve problems due to their personal performance-oriented working environment.
