Purpose – The purpose of this paper is to investigate the relationship between transformational leadership (TL) and the innovative behavior of Korean workers. To this end, this paper also examines whether knowledge sharing and perceived organizational support (POS) influence the above causal relationship. Design/methodology/approach – The paper used a cross-sectional design, with questionnaires administered to 356 employees working in Korea manufacturing firms to test the relationship between TL and innovative behavior through knowledge sharing and the moderating role of POS. Findings – TL was significantly related to both employee innovative behavior and knowledge sharing. The results also shown that knowledge sharing mediated and POS positively moderated the relationship between TL and innovative behavior of employees. Research limitations/implications – Future research should examine antecedents of knowledge sharing and measure the effect of TL in other level such as team level, to enhance generalizability. Data should be also collected longitudinally, to extend the current cross-sectional design. Practical implications – Understanding the link between TL and innovative behavior with mediating and moderating factors can provide useful information to increase positive leadership outcomes and innovation performance. Originality/value – The findings point toward a positive relationship between TL and innovative behavior with mediating and moderating factors. In doing so, the paper adds to a body of work where innovative behavior was connected with leaders’ behavior and organizational-level predictors.

In the era of a graying workforce, individuals and their employers are concerned with the impact of the graying workforce on the level of engagement at work. Contrary to the myths about older workers being less engaged, statistics have shown that the level of engagement is higher as people age. Within the broad framework of conservation of resources theory in the area of work engagement, the current study aims to clarify how older workers are more engaged at work than younger workers. Building upon socioemotional selectivity theory and continuity theory from a life‐span perspective, we explain how individuals gain more resources as they age, including the abilities to regulate emotion and to maintain a career identity. We argue that this positive relationship between age and resources explains why older people have high levels of work engagement. We tested our predictions with a sample of 613 workers in the United States. The study demonstrates that well‐regulated emotion and strong commitment to career mediate the positive relationship between age and work engagement simultaneously. These findings contribute to the understanding of an aging workforce's engagement in the workplace. © 2016 Wiley Periodicals, Inc.

The transfer of innovation between organisational members has recently drawn attention from both academia and business because corporate competitiveness is linked directly to the diffusion of innovation through an organisation. As the spread of innovation within an organisation depends on the efficient transfer of knowledge between members, this study focuses on the concept of knowledge withholding, which is known to disrupt this transfer. First, Herzberg's two-factor theory is used to prove that knowledge sharing and withholding are separate concepts and to explain the difference between them. Second, past studies on knowledge management are shown to have overlooked knowledge withholding in favour of knowledge sharing, leading to a paucity of information on the former. Third, knowledge withholding is classified into two separate behaviours: the intentional hiding and the unintentional hoarding of knowledge. Finally, four territorial behaviours related to knowledge withholding are summarised in order to suggest areas of future study.
