Labor issues

Company A employee X became ill while working and was taken to a hospital and died a few weeks later.Since Mr. X's family had heard before Mr. X's life that he was staying at work because he was too busy to go home, he thought that there was overwork due to work in the causal relationship with Mr. X's death. He filed a complaint with the Labor Standards Inspection Office through a lawyer.Based on the allegation, Company A conducted an internal investigation into Mr. X's working conditions, but could not confirm the working conditions that would lead to overwork.In the wake of this situation, the Labor Standards Inspection Office decided to sort out the arguments of both parties by saying, "Electronic devices that record all the work and living conditions of Mr. X, including the PC used by Mr. X at work. FRONTEO decided to conduct an investigation because it requested Company A to "investigate and clarify the facts."
