Final answer:
A manager who "leads with an iron fist" is an authoritarian leader, focused on achieving goals with minimal group input, which can be necessary in some situations but risks alienating team members.
Step-by-step explanation:
A manager who is said to "lead with an iron fist" typically adopts an authoritarian leadership style. This style is characterized by a leader who issues orders and assigns tasks with minimal input or feedback from group members. Such a leader is primarily focused on achieving goals and can be effective in situations where decisions must be made rapidly or where specialized expertise is required. However, this approach can also risk alienating employees or team members because of its top-down nature.
Authoritarian leaders are exemplified by some notable entrepreneurs, such as Mark Zuckerberg, who adopt this style to drive their organizations toward rapid and focused goal attainment. On the other hand, leaders like Joseph Stalin or Adolf Hitler have shown the extremes of authoritarian leadership, where power is exercised through fear and intimidation. Despite its potential downsides, there are scenarios where authoritarian leadership is necessary and can lead to clear, decisive action.
