Page 118, Chapter 5, 'Individual Change': The book discusses the Change Curve, noting that the initial phase following a change announcement is characterized by shock and denial, which is fundamentally a reaction to a perceived loss. The subsequent stage involves emotions like fear, anger, and self-doubt as individuals grapple with the implications of the change.

Section: 'The Change Curve': This university resource explains that the curve begins when a change is introduced, leading to a "dip in morale and performance." The initial stages are described with terms like shock, fear, and denial, all of which are rooted in a sense of loss. The subsequent stage of "resistance" is characterized by doubt, frustration, and uncertainty.

Part I, Chapter 3-7: While the original context is grief, this foundational work is the basis for the Change Cycle. The initial stages of Denial and Anger are direct responses to a significant loss. The emotional turmoil described in these early stages inherently includes feelings of uncertainty and doubt about the situation and the future. This model is widely applied to organizational change to understand employee reactions.
