Answer:
The correct option is lack of personal ethics
Explanation:
Fear of failure could be cogent reason behind employees' resistance to change since most employees would have gotten used to existing arrangement and any attempt to change it might be perceived a leaving one's comfort zone for unknown destination point.
The way individual perceive change can also be a rationale for opposing changes,some employees see changes as an opportunity to record new achievement while some might see as a way to expose their inefficiencies.
Another reason for opposing views to changes could lack of trust, in the sense that management might not keep to their promises made prior to implementing the changes,hence lack personal is the odd option and the correct option.
