Step-by-step explanation:
The approach to change management that highlights the willingness of senior managers to negotiate and bargain for introducing change is the c) Participative approach. This approach fosters a collaborative environment where leaders encourage group participation and consensus building in decision-making processes. It contrasts with the authoritarian style where communication flows from the top down and orders are given without much staff input. The participative style is akin to the democratic leadership style, where decisions are made collectively, and the laissez-faire leadership style, which is more hands-off. Both the participative approach and these leadership styles are linked to the concept of transformational leadership, where leaders inspire employees and encourage their input to bring about significant change within an organization.
