In this study, 31 not-officially-confirmed teachers as try out samples, and 48 not-officially-confirmed teachers for study samples. The incindental sampling was used for this study. Data analysis employed product moment correlation technique. The data analysis resulted in obtained correlation value rxy = 0,771 whereas p = 0.000 (p<0,01). This suggested there was very significant positive relationship between stress toward the future and the anger behavior of not-officially-confirmed teachers.
