In modern society, police officials are responsible for key security tasks such as crime prevention, crime response, and civil safety, and play a role in maintaining national safety and stability. Therefore, it can be said that the job satisfaction of police officials is an important factor that has a great influence on social stability and the effectiveness of law enforcement. In this study, an in-depth study was conducted to analyze the relationship between police officials' job satisfaction based on Herzberg's motivation and hygiene theory to examine the factors affecting police officials' job satisfaction. Herzberg's motivation and hygiene theory is one of the important theories for explaining and improving job satisfaction, and classifies job satisfaction and job dissatisfaction as other factors. According to the analysis, higher growth potential, promotion, praiseㆍrecognition, and achievement, which are Herzberg's motivating factors, can have a positive effect on job satisfaction, and higher hygiene factors such as communication, work environment, policyㆍ supervision, and salaryㆍallowance can have a positive effect on job satisfaction. These results support Herzberg's motivation and hygiene theory, and suggest that police organizations need to improve job satisfaction by strengthening organizational management and support. As active and active police activities of individual police officials are required, the following implications are derived based on the analysis results of this study. The first is a sense of accomplishment. As shown in the analysis results, it was found that the sense of achievement had a high effect on job satisfaction. If you feel rewarded and accomplished through your current work as a police officer, this will soon help you improve your ability and expertise. Second is the rationalization of the police personnel management system. A representative area of human resources management is promotion. This is because police officials, unlike other organizations, are a vertical class culture and have a large difference in authority and responsibility for performing their duties depending on the class. Therefore, measures should be devised to increase the rationality of the performance evaluation system and the fairness of promotion.
