Imagine a scenario like this: In a large, competitive company, there are two middle-level managers at a similar stage of career development. A is recognized as a capable and upright person in the company, while B has always been regarded as mediocre and even a little opportunistic. When an internal promotion opportunity arises, B feels that the number of promotion places is limited, and A, as a competitor, will undoubtedly become the strongest competitor. In order to monopolize the promotion and further control the department's resources, B planned an elaborate conspiracy. B began to create false internal emails and documents, forging evidence to show that A had used his position to seek personal gain during key decision-making processes and was even suspected of violating the company's financial regulations. B also deliberately contacted some colleagues who were not aware of the situation, and by selectively spreading incomplete "inside information", the news quickly spread within the department. These fabricated news were passed to the senior management, and then the company launched a preliminary investigation process. With the help of these false evidences, B acted extremely "honest and brave" in front of the senior management, as if he had discovered a series of misconduct by A, but in fact all the accusations were carefully planned and unfounded rumors by B. As the investigation deepened, A's name gradually became associated with the misconduct, and his previously good professional reputation was severely hit. At the same time, B used this opportunity to become famous in the eyes of management, not only successfully depriving A of his promotion opportunities, but also occupying more resources and influence in the subsequent department reorganization. In this situation, in order to gain greater professional benefits and power, B did not hesitate to fabricate events, forge evidence, and deliberately destroy A's professional image, ultimately gaining a more advantageous position within the group. The whole incident also reflects that when people are in a competitive environment, personal ambition may drive them to take extreme measures, violate professional ethics, and ultimately bring heavy blows to innocent people.
