Organizational change and innovation are generally treated as unquestioned goods, but some have argued that there exists a darker side to these phenomena. Change is often resisted or only grudgingly accepted by those involved and, given the assumed virtues of change and innovation, resistance has traditionally been considered an obstacle to overcome. This chapter will first consider the dark sides of change—that is, negative aspects, in particular change initiatives that are undertaken for ethically questionable reasons, using ethically questionable means, or resulting in deleterious consequences. Second, it reviews resistance to change—that is, an aversive cognitive, emotional, or behavioral response to a change initiative. Using a framework to consider the substance, processes, and outcomes of change initiatives, practical and theoretical implications are provided for a more nuanced approach to acknowledge the connections between perceptions of a change initiative as potential dark side judgments and resultant resistance behaviors.
