A B S T R A C TThis paper examines the effect of authentic leadership on leader trust, organizational identification, job performance, and employee loyalty within the context of a food-and beverage department in a hotel. The data were collected from 204 hotel employees and analyzed using structural equation modeling. Findings are as follows: authentic leadership had significant effects on leader trust and job performance, but does not affect organizational identification. Leader trust was found to have significant influences on organizational identification and employee loyalty, and fully mediated the relationship between authentic leadership and organizational identification. Organizational identification significantly affected both job performance and employee loyalty and plays a full mediating role between leader trust and job performance, and also plays a partial mediating role between leader trust and employee loyalty. Finally, job performance had a significant effect on employee loyalty.

PurposeHotels conducting international business are acknowledging the importance of an expatriate general manager (GM), to increase the effectiveness of their knowledge management system through the sharing of knowledge between expatriates and local employees. In the aspect of comparative leadership studies, this study attempts to compare and analyze the effects of knowledge sharing (KS) efforts, which are competencies of expatriate GMs and local GMs, on employee trust, organizational KS and employee loyalty.Design/methodology/approachData were collected from employees of 7 hotels managed by expatriate GMs among 16 franchising luxury (5-star) hotels, and from employees of 6 hotels operated by local GMs among 9 local luxury hotels located in Korea. Structural equation modeling method using SmartPLS 3.3.3 was used to analyze the data.FindingsExpatriate GM’s two-way KS influences affective trust but does not influence cognitive trust. Affective trust influences cognitive and organizational KS but does not influence employee loyalty. Cognitive trust does not influence organizational KS but influences employee loyalty. Finally, organizational KS significantly affects employee loyalty. In addition, in the analysis comparing the estimates between expatriate and local GM group, significant differences in groups were found for the impact of GM’s two-way KS on cognitive trust, for the impact of affective trust on organizational KS, for the impact of affective trust on employee loyalty and for the impact of cognitive trust on organizational KS.Practical implicationsThis study shows that knowledge management designs need to consider different effects of expatriate GMs’ and local GMs’ capabilities on employee attitudes and behavior considering cultural impacts. Expatriate GMs will greatly benefit their effort for KS by assuring employees that they are attentive to their needs, interests and problems.Originality/valueThis study not only contributes to the existing social capital theory but also provides managerial implications for human resources management in the hospitality field through a comparative study of KS efforts of expatriate and local GMs.
