Final answer:
During Lewin's change stage, managers should provide new information and perspectives to employees to help them understand and accept changes.
Step-by-step explanation:
During Lewin's change stage, managers should give employees new information, perspectives, and models for behavior. This is because Kurt Lewin's model of change involves unfreezing the current state, making the change, and then refreezing to stabilize the new state. Providing new information and models for behavior is crucial during the change stage to ensure that employees understand and accept the new processes, behaviors, or organizational goals. This stage is not primarily about making employees dissatisfied with the present situation nor about reinforcing the change—that comes later in the 'refreeze' stage.
