Stay away from fickle supervisor! Supervisors’ behavioral fluctuation diminishing the effect of job embeddedness on employees’ service behavior

This study examined how hotel employees’ job embeddedness influences their in-role and extra-role service behaviors, and under what boundary conditions this influence can be magnified based on the psychological ownership and information-processing theories. Using longitudinal data from a matched sample of 163 hotel employees and their supervisors in China, the moderated mediation analysis revealed that affective commitment mediated the effect of job embeddedness on in-role and extra-role service behaviors, while a supervisr's behavioral fluctuations moderated the mediation of affective commitment between job embeddedness and in-role and extra-role service behaviors; this mediation effect was stronger for employees with a supervisor exhibiting stable behaviors. These findings provide theoretical and managerial implications for tourism researchers and practitioners.
