Purpose: This study explores the politics of ideology in the process of sensegiving and sensemaking at a Japanese retailer in Hong Kong. Studies on power and politics are scarce despite key role of power and politics in understanding the factors behind the conflict between the management's policy legitimization (sensegiving) and employees' policy interpretation (sensemaking). By using the three dimensions proposed in the critical sensemaking approach (discourse, rules and contexts), this paper explores the complex mechanism of power and politics in sensemaking and sensegiving. Design/methodology/approach: Using 15 months of participant observation as a salesperson, this paper discusses how the Japan-centric customer service philosophy (dominant discourse), customer service policies and practices (organizational rules) and asymmetric power structure between the Japanese global headquarters and Hong Kong subsidiaries (formative contexts) are presented and perpetuated through the sensegiving–sensemaking process. Findings: Dominant discourse was observed in the management's sensegiving, which placed the Japanese style of customer service over others. This ethnocentric dominant discourse informed the creation of customer service policies, although the realization of the discourse was determined by the employees' conflicting interpretations of the organizational rules. As a formative context, an asymmetric power structure was present that positioned the Hong Kong subsidiary as subservient to the global headquarters in Japan. This shows that the political process of sensegiving and sensemaking deeply implicates the dominant discourse, organizational rules and power structure as central forces that determine the level of perpetuating ideology. Originality/value: This research illustrates the wider implications of power and politics in sensegiving–sensemaking studies and provides a complex picture of ethnocentric management.
