Kangwonland has been the only domestic casino and movement in casino industry has not been notable, but if more domestic casinos open in the future, it is inevitable those casino workers will move for the better remuneration and working condition. In this situation, in order to keep the previous customers and create new ones, we need to realize the importance of workers who lead customers' satisfaction. For this purpose, we need to find out the influential factors which affect the job satisfaction of the workers and try to turn the worker's satisfaction into good customer service. Despite the importance of casino workers, previous researches about casino industry focused only on economic effects, and there was few systematic research about the casino workers considering their job characteristics who provide services to customers in field. Therefore, this research aims to grasp influential factors of job satisfaction of casino dealers, analyze satisfaction and find out the ways to enhance the satisfaction. This will eventually help profit maximization of the casino company by improving the service quality. For this purpose, research was conducted whether job itself, relationship with the supervisors, promotion, remuneration, working environment affect the job satisfaction of the employees meaningfully and whether job satisfaction changes according to demographic characteristics.
