Teachers’ emotional well-being is incredibly crucial for both teachers themselves and children. When considering this importance, researchers need to explore ways to enhance teachers’ emotional well-being. Before developing an invention program, however, it requires performing in-depth research to give fundamental data for intervention. As part of its efforts, thus, this study intends to examine whether promotion focus and job crafting have a mediation effect on the relationship between calling and emotional well-being. For this purpose, this study collected data from 337 elementary school teachers. Subsequently, the current work administered four scales measuring calling, promotion focus, job crafting, and emotional well-being to them. The findings found that promotion focus and job crafting showed full mediation effects on the relationship between calling and emotional well-being, respectively, with a sequential mediation of promotion focus and job crafting. Finally, this paper critically discusses the implication of which researchers and leaders should be aware and then suggests directions for future researchers.
