Resistance to change is a common reaction that occurs when people perceive a threat or loss from the change. Resistance can be shown in different ways, such as denial, avoidance, passive-aggressive behavior, or sabotage. Sabotage is a deliberate attempt to undermine or obstruct the change. To deal with sabotage, change leaders should try to understand the reasons behind it and address them constructively. One possible action is to allocate important change tasks to the saboteurs, as this can increase their involvement, ownership, and accountability for the change. The other options are not suitable responses, as they either ignore, isolate, or accept the sabotage, which can worsen the situation and damage the change.References: https://apmg-international.com/sites/default/files/Change%20Management%20Foundation%20Sample%20Paper%2028%20-%20v1.0.pdf (page 11)
