The purpose of this study is to explore the job satisfaction and the differences between personal attribute variables (gender, marital status, age and educational background) and work attribute variables (seniority, position type), as well as the correlation of extrinsic and intrinsic job satisfaction of Chengjheng Juvenile Correction School's staffs. Total staff of 136 were surveyed by questionnaire and 122 copies were returned with 90% return rate. This study found that the rank of job satisfaction was stated as follows: interpersonal relationship, work characteristics, social status, work itself, work environment, executive leadership, salary and welfare. Among personal and work attribute variables, there was no significant difference of overall job satisfaction from gender and marital status. Staffs who are 30 years old and below at Chengjheng high school have higher satisfaction in executive leadership, work environment, interpersonal relationship, social status, and work characteristics, as well as overall job satisfaction than those who are 41 to 46. Staffs graduated from university have higher satisfactions in work itself and social status than those who graduated from senior and vocational school. Regarding seniority, staffs with tenure of between 7-9 years at Chengjheng high school have higher satisfaction in work itself than those with 4-6 years. Staffs with tenure of 3 years and less have higher satisfaction in executive leadership, work environment, salary and welfare, social status, and work characteristics, as well as overall job satisfaction than those with 4-6 years. Guiders at Chengjheng high school have lower satisfaction in interpersonal relationship than other staffs. However, teachers have higher satisfaction in work characteristics, and overall job satisfaction than security guards. Moreover, extrinsic job satisfaction of executive leadership, work environment, interpersonal relationship, salary and welfare are found positively correlated to intrinsic job satisfaction of work itself; social status, and work characteristics.
