25. The host thus forming a single united body, it is impossible either for the brave to advance alone, or for the cowardly to retreat alone. This is the art of handling large masses of men.

民既專一則勇者不得獨進怯者不得獨退此用衆之法也

Sun Tzu

In this quote, Sun Tzu is talking about the importance of unity and cooperation among members of an army. He is saying that if the members of an army are united and work together as a single body, it will be impossible for individual soldiers, whether they are brave or cowardly, to act on their own. Instead, they will be forced to act as part of the group and follow the orders of their leaders. This is the key to effectively managing and leading large numbers of soldiers in battle.

When a company's employees are united, individual employees will not act on their own. Effective leadership of a business requires teamwork and following direction.

When a company’s employees are united, they work together towards common goals and objectives. This means that individual employees cannot act independently on projects that are not aligned with the company’s priorities. By working together, employees can ensure that the company’s resources are used efficiently and effectively to achieve its goals. By acting alone, employees may waste the company’s time and resources on projects that do not contribute to its success.
