Abstract
Drawing on the social exchange theory (SET) and research on leadership influences, we developed and inspected a multilevel model to test the conditions and mechanisms through which a leader's behavioral integrity (LBI) deters workplace ostracism (WO). We used trust as a mediator and the narcissistic personality of a leader as a boundary condition in the connection between a LBI and WO. Data were collected from 249 employees working in different five- and four-star hotels in Pakistan over three time lags. The statistical results revealed that a LBI reduces WO. Additionally, a LBI has an indirect effect on WO through interpersonal trust. We did not find statistical support for the moderating role of the narcissistic personality of a leader in the relationship between a LBI and WO. Implications, along with limitations and future research directions, are also discussed.
