This study investigated the influence of principals’ decision-making styles and ethical leadership on teachers’ job performance. Employing an explanatory sequential mixed methods design, the research first gathered quantitative data to determine the levels of principal decision-making styles, ethical leadership, and teachers’ job performance among public secondary school teachers in Region XI, followed by qualitative inquiry to further explain and validate the quantitative findings. A purposive sampling technique was utilized in selecting the teacher-respondents for the survey, which served as the quantitative phase. Subsequently, in-depth interviews (IDIs) and focus group discussion (FGD) were conducted to substantiate and clarify the salient quantitative results. The quantitative data were analyzed using mean and regression analyses, while the qualitative data were examined through thematic analysis. The findings revealed that principals’ decision-making styles were rated high, indicating that they were oftentimes evident; ethical leadership was rated very high, signifying that it was always manifested; and teachers’ job performance was also rated very high, meaning it consistently met expectations. Moreover, the combined effect of principal decision-making styles and ethical leadership was found to significantly influence teachers’ job performance. The qualitative phase confirmed the quantitative results, highlighting the consistent high and very high ratings and reaffirming the significant combined influence of the two independent variables. Data integration was characterized by connecting-confirmations, wherein the qualitative findings reinforced and elaborated on the quantitative outcomes.
