Final answer:
People may resist a change or decision in their organization if leaders fail to obtain 'buy-in' from employees, if the change does not align with employees' personal goals, or if the leaders do not communicate the change effectively.
Step-by-step explanation:
When people resist a change or a decision in their organization, it can be due to several reasons. One possible explanation is that the leaders failed to obtain 'buy-in' from their employees. This means that the employees do not feel involved or included in the decision-making process and therefore, are more likely to resist the change. Another reason could be that the change does not align with the personal goals of the employees. If the change is perceived as threatening their own interests or objectives, they may resist it. Effective communication by leaders is also important in gaining acceptance and minimizing resistance to change.
