The aim of this paper is to examine the relationship between emotional intelligence and conflict resolution among secondary education teachers in Greece. The research sample consists of 130 high schools’ teachers in Greece. Data were collected using a structured questionnaire, concerning teachers’ working environment, their behavior during workplace conflicts as well as their emotional intelligence and were analyzed using descriptive and inductive statistics. The statistical analyses have revealed that the main reason for workplace conflicts in secondary schools is the existence of informal groups. In addition, emotional intelligence seem to have a direct relationship with conflict resolution styles, while a negative relationship between emotional intelligence and the frequency of involvement in workplace conflicts is observed. Furthermore, it was found that holding a position of responsibility does not play a significant role in conflict resolution style adoption. The research results show that the solution-oriented method is the most popular amongst the other conflict resolution styles. Last, it was found that the average score of emotional intelligence among the respondents was high.
