As the number of demonstrations mobilized by police is expected to increase after the COVID-19 complaint, the experience of riot police officers in the process of managing and responding to demonstrations is expected to increase. While previous studies have verified the impact of violent experiences on the intention of leaving work, the number of demonstrations and corresponding violent experiences of riot police officers is expected to increase. The mandatory police system was completely abolished in 2023, and police riot police are in the process of replacing it, but the number of mobile police officers who replace compulsory police is very short of 30 percent. In this situation, it will be difficult to effectively accomplish the task of establishing an advanced rally demonstration culture where law and principles are observed if existing or new police officers break away from their duties.
 Therefore, the purpose of this study is to analyze the impact of violent police experience on the intention to leave work, to analyze whether social support for mobile police has the effect of adjusting the relationship between violent police experience and intention to leave work. Accordingly, 829 people who said they had experienced violence in a survey of riot police officers belonging to the Seoul Metropolitan Police Agency in 2021 were used for analysis. The analysis revealed that the experience of riot police officers has a positive effect on their intention to leave the job, and that social support has the effect of controlling the relationship between the experience of riot police officers and intention to leave the job. Based on the results of these studies, they presented policy recommendations to prevent and manage the intention of mobile police officers to leave their jobs.
