Organizations are increasingly required to improve their ability to enhance employees' support or acceptance for change initiatives. In studies that have examined the conditions in which employees support organizational change, researchers have focused on various attitudinal constructs that represent employees' attitudes toward organizational change. The constructs, which frequently serve as key variables in these studies, include readiness for change, commitment to change, openness to change, and cynicism about organizational change. These constructs have distinct meanings and emphases and therefore they can provide us with different information regarding employees' evaluation of and concerns about particular change initiatives. In this literature review, the author discusses how the constructs are defi ned in the organizational change literature and synthesizes the antecedents of each construct. Based on the discussion, it is proposed that the constructs are susceptible to situational variables, and may change over time as individuals' experiences change; therefore, they are better conceptualized as states than as personality traits.

Individual readiness for organizational change reflects the concept of unfreezing proposed by Lewin (1947/1997b) and is critical to successful change implementation. Understanding the conditions conducive to individual readiness for organizational change, instead of the more traditional focus on resistance to change, can be useful for designing and implementing effective human resource and organization development (HROD) interventions. In this conceptual article, we examine the concept of individual readiness for organizational change as well as its relationship to change strategies and organizational culture. A review of literature on change strategies and a learning culture suggests that individuals are more likely to have higher levels of readiness for organizational change when (a) they experience normative-reeducative change strategies and when (b) they perceive their work environment to have the characteristics associated with a learning culture.

Purpose The purpose of this paper is to investigate the moderated mediation model in which the effect of perceived organizational support (POS) on knowledge sharing intention is mediated by levels of individual affective commitment to the organization, while the relationship between POS and affective commitment is moderated by organizational tenure. Design/methodology/approach Hypotheses on mediation, moderation and moderated mediation were tested with data collected from Korean for-profit organizations. Conditional process analyses with bootstrapping supported all three hypotheses. Findings The findings demonstrate that the relationship between POS and knowledge sharing intention is mediated by affective organizational commitment. In addition, the mediation effect is strengthened when an individual’s organizational tenure is low. Theoretical and practical implications and directions for future research are followed. Originality/value This study contributes to the literature on knowledge sharing by providing a basis for understanding the mediating mechanism through which POS influences knowledge sharing intention, and, ultimately, organizational functioning via individual affective attitude. This is the first attempt examining the role of organizational tenure as a key contingency factor in knowledge sharing. By investigating the underlying logic of individual intention to share knowledge, this study expands the current spectrum for knowledge management.
