The present study aimed to investigate the impact of managers’ personality traits and social skills on teachers’ job security. The population of this study included all the elementary school teachers in Tehran, and a sample size of 300 teachers was studied using Cochran's formula. In this study, data collection tools involved Matson Social Skills Questionnaire (1983), Seyed Muhammad Hussein Kamani Job Security Questionnaire (2000), and Costa and McCrae Personality Traits Questionnaire (1992). In this study, SPSS software version 22 was applied for data analysis. Descriptive statistics (mean and standard deviation) were utilized for data description, and inferential statistics such as regression analysis were used for data analysis. The results indicated that personality traits (neuroticism, adaptability, extroversion, conscientiousness, openness, and openness to experience) and social skills (appropriate social skills, antisocial behaviors, aggression and impulsive behaviors, dominance, excessive self-confidence, relationship with peers) affect job security.
