PurposeThe challenge of attracting and retaining high performing call center employees is significant. Research in general has shown a link between personality factors and job performance. This study aims to focus on examining the relationship between personality factors and performance using service performance indicators and further, to study the role of emotional exhaustion in this relationship in the context of call centers.Design/methodology/approachUsing a structured questionnaire 194 call center employees and their supervisors were surveyed in eight call centers in five companies in the insurance and telecommunications industries.FindingsResults using structural equation modeling showed that, with the exception of extraversion/introversion, all of the personality dimensions of the five factor model: conscientiousness, agreeableness, openness to new experience and emotional stability as well as locus of control were significantly related to one or more of the performance measures. Emotional exhaustion mediated the relationship between emotional stability and locus of control and intent to turnover.Research limitations/implicationsThe study examined the mediating role of emotional exhaustion in the relationship between personality and performance; the impact of stressors needs further study.Practical implicationsInsights gained from this study could be used to develop selection strategies, work redesign programs and training that would benefit the organization by reducing employee costs and enhancing employee wellbeing.Originality/valueThis study uses service performance assessment data obtained from supervisors to establish the link between personality, emotional exhaustion and service performance among call center employees.
