PurposeThe effect of empowering leadership on knowledge sharing is well defined, but factors that stimulate employees for knowledge sharing are still limited. Therefore, this study aims to address to what extent empowering leadership is desirable to create a trustful and fair environment that is conducive for an employee’s knowledge sharing.Design/methodology/approachThrough integration of social exchange, equity and uncertainty management theories develop a moderating mediating model that links empowering leadership to knowledge sharing. Three-wave data collection from the sample of 375 managers–subordinates’ dyads was done in Pakistan textile industries.FindingsHierarchal regression analysis and bootstrapping method were applied to test the hypotheses. The results indicate that affective trust partially mediates the relationship between empowering leadership and knowledge sharing. More especially, the findings demonstrate that the relationship between empowering leadership and knowledge sharing becomes strong with high level of distributive and procedural justices.Practical implicationsThis research study uses empowering leadership as a proposed motivational pathway for stimulating employee’s knowledge sharing through development of affective trust and buffering effect of distributive and procedural justices.Originality/valueMost of previous research in knowledge sharing just cynosure organizational-level elements like leadership and organizational justices but deteriorate individual factors like trust. Therefore, this study will combine both organizational- and individual-level factors for urging employees for knowledge sharing.

Given the pivotal function of ethical leadership (EL) in the hospitality industry, this study explains how moral guidance can help to reduce mental stress. The modern complex and hectic working style of organizations demands ethical conduct, in order to sustain the positive behavior of employees for knowledge sharing (KS). For this reason, in this study, we restrict our awareness to the usage of social media (SM) for social identity and aspects of subjective well-being (SWB) for happiness intensity. The time-lag method is applied for data collection from 406 supervisors and subordinates of the hotel industry in Pakistan. Partial least squares structural equation modeling (PLS-SEM) and bootstrapping are utilized to scan the data. The results of the current study demonstrate that ethical leadership provides motivational strength for knowledge sharing amongst employees. Moreover, the serial mediation effects of subjective well-being and social media boost knowledge sharing by the induction of ethical values. Our findings indicate that knowledge sharing is an important product of subjective well-being and social media. Therefore, we recommend that managers focus on ethical leadership values and employee well-being (e.g., life satisfaction), as well as highlight the individuality of employees to promote knowledge sharing. The presented research adds to the literature by establishing a new connection between ethical leadership and knowledge sharing by opening the black box of contextual (i.e., ethical leadership) and developmental (i.e., subjective well-being and social media) factors.
