The assistance of host-country nationals (HCNs) both within the workplace and in the external environment plays a significant role in expatriate adjustment and work performance on international assignments. Extant research exploring antecedents of HCNs' attitudes and behaviors toward expatriates focuses on personal and intrapersonal factors but overlooks organizational contextual effects. In this study, we propose and test a model that HCNs' willingness to help expatriates is influenced by HRM practices in international subsidiaries of multinational enterprises (MNEs). Results of analyzing data collected from Chinese subsidiaries of South Korean MNEs showed that high-commitment HRM practices directly and indirectly influence HCNs' willingness to help expatriates through the mediation of perceived organizational support (POS). Socially responsible HRM indirectly influences the criterion variable through the mediation of organizational identification. Moreover, POS and organizational identification sequentially mediate the effect of high-commitment HRM on HCNs' willingness to help expatriates. These findings shed some light on organizational antecedents that go beyond personal and intrapersonal factors of HCN attitudes and behavior toward expatriates.
