The number of samples was determined by the Slovin formula at a 95% confidence level, so that there were 94 teachers consisting of 29 male teachers and 65 female teachers. The instrument used is a questionnaire. Furthermore, reliability and validity tests were carried out. The data were analyzed using coefficient, correlation and regression analysis techniques. The results of the coefficient calculation show that there is a significant relationship, (1) the variable of the teacher's work characteristics X1Y = 3,300, (2) the variable of the principal's leadership X2Y = 2,92, (3) the variable of the school climate X3Y = 5,537 and (4) the work characteristics of the teacher, Principal leadership and school climate X1X2X3Y = 3.892 at the 5% confidence level. Looking at the strength of the relationship using the Spearman rank test, it was found that (1) the variable of teacher work characteristics X1Y = 0,542** is interpreted as having a strong and direct correlation, (2) the principal leadership variable X2Y = 0.678** is interpreted as a strong and direct correlation, (3) the variable school climate X3Y = 0.806** means a very strong and unidirectional correlation. The results of the regression calculation show that the contribution of teacher work characteristics to satisfaction is 38%, for principals' leadership 22.6% and for school climate 42.8%. The suggestion is that it is necessary to develop other variables that contribute to teacher job satisfaction.
