That's not correct.

When you are in a firefighting role, your job is to fix the fire, not appease Jack and build relationship with him, the person whose practices created the situation to begin with. Unfortunately, even in those cases the highest level of stakeholder who engaged your firefighting service may not be willing to tell Jack's manager or Jack that he will do what he is told or he will be removed.

Jack's gatekeeping is what keeps Jack employed. The company's ultimate bosses will need to make decision if they want to remove Jack and solve a problem or if they do not care that much that the problem is quickly solved. In the vast majority of cases no one in the company who can fire Jack wants to be seen as a bad guy.
