Final answer:
A personnel decision of line management can be reversed by higher executive management for the good of the organization, highlighting the hierarchy in decision-making.
Step-by-step explanation:
When a personnel decision of line management must be reversed for the good of the organization, the overruling is done by higher executive management. This is an example of the hierarchical nature of organizational decision-making. Line managers are responsible for direct management of employees and the daily operations of a business, while executive managers, such as CEOs or VPs, have the authority to override decisions when they believe it serves the broader goals and health of the company.
