Acknowledging inter-individual differences is essential to understanding experiences. This study examined the relationships among personality traits, occupational burnout, resilience, and career commitment, using data from 220 Iranian EFL educators and four standardized questionnaires. Results revealed significant correlations between the Big Five traits and the variables examined. Extraversion (r = -0.282, p < .001), conscientiousness (r = -0.201, p = .003), and agreeableness (r = -0.193, p = .004) were negatively correlated with emotional exhaustion, indicating protective effects. Neuroticism correlated positively (r = 0.182, p = .007), underscoring the need for emotional support. Neuroticism was not significantly related to depersonalization (r = 0.081, p = .234), suggesting distinct causes. Extraversion (r = 0.326, p < .001) and conscientiousness (r = 0.247, p < .001) were positively associated with personal accomplishment; neuroticism was negatively associated (r = -0.197, p = .003). Resilience correlated negatively with neuroticism (r = -0.397, p < .001) and positively with extraversion (r = 0.364, p < .001), agreeableness (r = 0.225, p = .001), conscientiousness (r = 0.298, p < .001), and openness (r = 0.161, p = .045). Career commitment was positively linked to extraversion (r = 0.275, p < .001) and openness (r = 0.163, p = .015), and negatively to neuroticism (r = -0.218, p = .001), with no significant correlation with agreeableness (r = 0.041, p = .545) or conscientiousness (r = 0.119, p = .079). Agreeableness was most common; extraversion least. Findings underscore personality’s key role in performance and coping with demands.
