PurposeThis study aimed to contribute to the field of Human Resource Management (HRM) by providing a critical review of existing scholarly research and a thematic analysis of the workforce nationalization domain in the Gulf Cooperation Council (GCC) countries. To strengthen the literature on this topic, it seeks to identify key gaps and areas for further exploration.Design/methodology/approachA two-step systematic research methodology (qualitative and quantitative) and a thematic analysis of empirical and theoretical studies were used in this study. The quantitative review was conducted using a predesigned coding framework.FindingsThe study identified and discussed four perspectives of workforce nationalization in the GCC countries. These were (1) the conceptualization of workforce nationalization; (2) the role of institutional policies in achieving it; (3) the practices and outcomes of nationalization efforts and (4) the impact of gender and women in the nationalization process.Research limitations/implicationsThis study has several limitations, which the authors have addressed by proposing several future research avenues. For example, the reviewed studies are skewed toward certain countries (e.g. UAE and Saudi Arabia), which limits the generalizability of their findings.Practical implicationsA more comprehensive definition of nationalization, development of qualitative and quantitative measures to enhance HRM practices and outcomes, and the identification of alternative approaches to improve the employment of locals are emphasized as needs. Additionally, revised measures and mechanisms to rectify negative perceptions about entitlement and the revision of policies to integrate females in the national labor force are suggested.Originality/valueWorkforce nationalization initiatives in the GCC region offer a unique and rich research phenomenon replete with managerial, organizational, economic and political dilemmas. The investigation of this phenomenon would profoundly enlighten employers, policymakers and scholars.
