Moderating effect of perceived organizational support on the relationship between leader-member exchange and expatriate voice in multinational banks

Purpose The purpose of this paper is to examine the effects of home and host country leader-member exchange (LMX) on expatriate voice and determine whether perceived organizational support (POS) moderates the relationship between home or host country LMX and expatriate voice. Design/methodology/approach This study surveyed 300 expatriates (expatriation of at least six months) working for Taiwanese banks. The participants had expatriated to Cambodia, Indonesia, Japan, Malaysia, Myanmar, the Philippines, Singapore, the USA and Vietnam. Convenience sampling was adopted. Findings Based on an analysis of 132 expatriates working for Taiwanese banks, home and host country LMX were positively related to expatriate voice. Moreover, host country LMX accounted for more variance in expatriate voice than home country LMX did. Financial POS moderated the relationship between home country LMX and expatriate voice. Career POS and adjustment POS moderated the relationships between home and host country LMX and expatriate voice. Originality/value In the field of expatriate management, whether expatriate voice is influenced by home and host country LMX requires further exploration. To the best of the authors' knowledge, this is the first study to examine the effects of home and host country LMX on expatriate voice in host countries, as well as the moderating effect of POS on the aforementioned relationships.
