Leadership is generally considered helpful for team knowledge sharing. However, differences in the influence of different leadership styles on team knowledge sharing mechanism is still unclear. To understand different leadership style foster team knowledge sharing, this study focuses on leader–follower trust during team interactions. From the perspective of leadership as social problem solving, we argue that transformational leadership and authoritative leadership are different linked to team knowledge sharing. Through the collection of a sample of 791 valid questionnaires in China, we used the structural equation model to test the theoretical model. Results showed that: (1) Transformational leadership was positively linked to explicit and implicit knowledge sharing, while authoritative leadership was positively linked to explicit knowledge sharing. (2) Trust tendency mediates the relationship between authoritative leadership and knowledge sharing. (3) Supportive and bureaucratic culture moderate the influence of trust tendency on implicit knowledge sharing, such that the positive relationship is stronger for the low-quality of supportive culture and the high-quality of bureaucratic culture. Finally, The study’s implication for theory and practice were discussed, its limitations were identified, and directions for future research were suggested.

Based on the 2017 China General Social Survey data, with 5,439 observations as research objects, this paper empirically tests the impact of flexible employment on workers’ wellbeing and introduces labor income as mediator and social security as moderator to explore the mechanism of action. The empirical results show that: flexible employment has an inverted U-shaped relationship with workers’ wellbeing, which indicates that increasing employments’ flexibility will first rise and then reduce their perceived subjective wellbeing after reaching the peak; labor income plays a mediating role in the relationship of flexible employment and wellbeing of workers; social security moderates the mediating effect of labor income whereas the moderating role in the relationship between flexible employment and workers’ wellbeing is not observed. Implications and future development of flexible employment are discussed.
