The purpose of this study is fifth fold. The first one is to test the hypothesis that the rise of the position is proportional to the ratio of plateaued employees in the corresponding position. The second one is to investigate the differences in work values between plateaued and non-plateaued employees. The third one is to test the hypothesis that plateaued employees perceive their jobs as job enrichment of lower standard than non-plateaued employees. The fourth one is to test the hypothesis that career consciousness of plateaued employees is lower than that of non-plateaued employees. The fifth one is to investigate the differences in the relationship between perception of job characteristics and career consciousness between plateaued and non-plateaued employees. The facts and conclusions in this paper were drawn by using 216 employees in nine enterprises. About the first one, after using chi-square test, it was clear that the rise of the position isn't proportional to the ratio of plateaued employees in the corresponding position. About the second one, after using frequency distribution, it was almost clear that there isn't much difference between plateaued employees' work values and non-plateaued employees' them. About the third one, after using a t-test, it was clear that plateaued employees perceive their jobs as job enrichment of lower standard than non-plateaued employees. About the fourth one, after using a t-test, it was clear that career consciousness of plateaued employees is almost lower than that of non-plateaued employees. About the fifth one, after using multiple regression analysis, it was almost clear that the relationship between the perception of job characteristics and career consciousness in plateaued employees is stronger than that of non-plateaued employees. The probability that job design is more effective for plateaued employees than for non-plateaued employees, etc. was pointed out.
