Abstract: Compulsory citizenship behaviour (CCB) refers to employees who perform extra-role behaviour against their will. The study is among one of a handful on compulsory citizenship behaviour if compared with organisational citizenship behaviour (OCB), which are directed toward individuals (OCBI) and an organisation (OCBO) as a whole. Thus, this study mainly focuses examining the effect of intention to leave, job stress, sucker effect, burnout, organisational politics, negligent behaviour, and conflict between colleagues on compulsory citizenship behaviour. A total of 100 academic staff from private higher education institutions in Melaka participated in this study. Self-administered questionnaires were used for data collection and SmartPLS was employed to perform the analysis. The findings of this study reveal that negligent behaviour and organisational politics have a significant direct relationship with compulsory citizenship behaviour. This study not only has noteworthy contributions on enriching the available literature on compulsory citizenship behaviour, but also provides some important insights to employers in private higher education institutions in relation to their human capital management, which focuses on compulsory citizenship behaviour.
