What experiences have you had in hiding for many years and finally succeeding in revenge?

Two years ago, as a rookie, I entered a company and was responsible for business. Like other rookies, relying on their academic qualifications, they always feel that their status is a little higher than others. So in the first four months, I was basically ignored. I did the most work, had the worst reputation, received the most small reports from my boss, and had the worst performance. I didn’t even have lunch with me. Until one thing happened, I was doing business comparisons. In fact, customers are willing to believe me. One day, a big customer quietly told me: In fact, you don’t know, your colleagues have already taken your plan many times, and pointed out many flaws in it, and asked me if I want to try them. Yes, it’s just that I want to trust you and pick you up. That's right, the old employees are poaching your customers with your ready-made information. Well, how to fight back? One person must not act wisely against a group of people. There is a saying in "Those Things in the Ming Dynasty" that "Small people have no vision, and arrogance tends to cause trouble." Therefore, when defeating them one by one, you should defeat the strongest ones first, and the weak ones will naturally fall behind. Be honest. If you pick the weak one, the strong one will definitely help. The cause still lies with the secretary, and the exclusion is reflected in all aspects, including salary settlement, performance appraisal, attendance appraisal, customer return visits, and complaint acceptance. I found some employees who were also treated differently by secretaries and talked about some things. I am like a newbie who likes to gossip, so I will naturally start to add jealousy to the description of the old bird in order to show his status. Then the boss held a meeting, some old employees were fired, secretaries were interviewed, and the old employees got rid of each other's responsibilities, but somehow they let the boss know, yes, I said it, through the router and hard drive. The secretary resigned soon after.
