The aim of this study was to empirically investigate a set of personality traits based on self-evaluations in relation to workplace deviance among volunteers at one of the national Emergency Relief departments, and to determine the importance of personality characteristics in contributing to volunteers' workplace deviance. A cross-sectional research was conducted with self-reported questionnaire. The participants were 200 volunteers attached to six emergency relief centers in Peninsular Malaysia. Data were analysed using SPSS version 19.0 software. Data analysis procedures; descriptive statistics, Pearson product-moment correlation and hierarchical multiple regression analysis were conducted. The findings confirmed the importance of taking personality traits into consideration during the process of recruitment of volunteers to minimise workplace deviance. This study contributes on the crucial role of volunteers' personality traits that can be an imperative factor to minimise workplace deviance.
