Teachers, as individuals outside the classroom, deals with their problems yet are still expected to display desirable dispositions during student interaction. Thus, the strategy for regulating thoughts and emotions is vital for effective teaching. This study aims to measure Filipino teachers' problem compartmentalization ability, their level of emotional intelligence, and teaching performance, mainly when they experienced personal issues. It also seeks to determine the relationship among variables. Validated researcher-made and adopted instruments were administered to the 140 teachers from different public schools in the Cebu province, Philippines. The tools were subjected to validity and reliability tests. The gathered data were analyzed using the weighted mean and Spearman rho coefficient. Findings revealed that Filipino teachers have a high ability to compartmentalize their problems. Also, they have a high level of perceiving, understanding, managing, and using their emotions. They also display positive disposition when they are in the classroom showing their good performance despite their personal issues. Statistically, Filipino teachers' emotional intelligence and their problem compartmentalization ability were positively and significantly correlated to their teaching performance. Hence these approaches may be included by the school leaders in teachers' training for the improvement of their well-being.
