This study aims to explore the effects of teachers' psychological capital competencies on their emotional labor competencies based on their perceptions. It follows a quantitative research design adopting survey method. Data were collected from 266 teachers working in Siirt Province, Turkey. The results show that teachers have high levels of positive psychological capital (all self-efficacy, optimism, trust, extraversion, and hope dimensions) and though relatively low compared to psychological capital competencies, they often display emotional labor behaviors. It was also found out that PsyCap competencies teachers possess have an impact on their tendency to display emotional labor behaviors. The study presents valuable theoretical and practical implications for research on PsyCap and emotional labor at school organizations.
