The purpose of this study is to define the vocational development process through balancing duties and union activities in the part-time operating officer. Research questions are as follows. How do officers become officers and How role and job awareness and behavior change? What factors affect changes in job awareness and behavior? The survey targeted 16 officers (average age: 36.3). Semi-structured interviews were conducted on 15 subjects. A verbal protocol was made for the interview contents, which was then analyzed by the modified grounded theory approach (M-GTA). It was determined that the theoretical saturation was reached with 66 concepts, and from the inter-conceptual aspect, they were arranged into 14 categories and 5 category groups. There is a hesitation and a reason to be appointed before becoming an officer, changes in role and job awareness and behavior through executive experience. There are both hardships and rewarding experiences, and the experience gained because of officers accumulates.
