심리 상담 운영이 휴먼에러에 미치는 영향

Abstract

There are many types of stress for workers. Stress cause human error and further inflicts negligent accident during the operation. If it aggravates, stress can lead a depression or even suicide. This kinds of behaviors is a partial results of uneasy elements that indwells on worker's mind and Korea ranked number one country in terms of suicide rate among Organization for Economic Cooperation and Development (OECD) countries. It cannot be denied that this does not be generated from stress. Assembly process of car industry, where frequent suicide has been noticed, consists of conveyor belt due to the nature of the industry, and this puts a lot of pressure for workers. Even if they have difficulties, workers cannot easily get a break and have to endure even in the case of poor communications with co-workers. In addition, as work has to be done in a special environment; night time, many workers suffer from sleep deprivation, have difficulty in maintaining normal social contacts with family and others, and feel alienated as social activities such as relationship with friends, official social gathering, and cultural events are constrained. For this reason, matters regarding mental health such as relationship between individual, family and spouse and interpersonal conflicts have been emerging major concerns of safety concern. According to the research by Korea Productivity Center about mental health state of 10,000 Korean workers, which can impact productivity of companies, the average score was 50 points, which is equivalent to a serious condition to the extent of requiring treatment. Moreover, job stress of 7,000 workers from 254 businesses across the country, 73% has been exposed potential job stress and 22% showed severe stress, according to the research of the Korea Institute of Occupational Stress. Korea, where working hours are 44.6 hours a week which is the most among OECD countries, workers' job stress is the world’s highest. This is higher than that of Japan; 61.5%, the United States; 40% and EU; 28%. The bigger problem is that workers take the job stress for granted. This problem is more serious in the domestic auto manufacturing plants. For the last four years, 19 people committed suicide in the automotive workplace and 11 (0.034%) committed suicide in 2011 alone. This rate is higher than that of national suicide rate (31.7 out of 100,000 populations; 0.032%). Judging by this, it can be inferred that restriction in social life and inconvenience in life cause significant stress for shift workers and directly and indirectly generate mental and physical problem by inflicting various interference over family and social life. In addition, continued increase in suicide due to this phenomenon raises more and more labor and management conflicts and compensation issues. Thus, car manufacturing workplace needs to aggressively introduce suicide prevention and treatment system through company-wide and active psychology consultation. This study focuses on automobile manufacturers so that it could discover causal factors generating human error and prepare countermeasures to prevent them in advance. In addition, by measuring stress level depending on occupational group for those in car manufacturing industry using conveyor belt, this study aims to empirically analyze the relationship between stress level and causal factors generating human error. Finally, it plans to suggest effective measures for controlling job stress by operating psychological counseling as a measure to reduce human error.
