Secondly, gradually adjust the distribution of personnel, try to make the employees of new and old companies cross, and avoid forming a large group, which has hidden dangers to the stability of the company.
Furthermore, the idea gradually penetrates into the boss's resources, and you can take over some of his resources, so that he can alert his position and put an end to his broken jar or arrogant mentality.
Then, find an opportunity to clean up once, remove one or two people from the middle level and replace them with their people to achieve the purpose of vigilance and avoid confrontation between the two sides. The new middle class, although originally a minority shareholder, will gradually rely on the major shareholder after this incident, and everyone will plan for themselves. As long as these middle-level cadres have a tendency to move closer to major shareholders, they should quickly win over and give sweetness. In this way, the boss can only compromise in order to avoid being overhead. And the people below are even less likely to make trouble. The focus is on the middle level, so the middle level is cut and the bonus is also the middle level.
Finally, wait until the minority shareholders are more attached, and then find another time or opportunity. Carry out comprehensive reform and end the privatization of company property, but try to let bygones be bygones. I believe there is pain, but the future is still beautiful.
