I wonder if you have ever wondered why the second person has become so arrogant? Is it because he is an arrogant person? In your opinion, he is arrogant when he has skills, but can his skills be higher than yours? The reason why he dares to be arrogant to you is because you are too dependent on him! To tell the truth, in fact, the problems of these two people are the same, and they are also on you (don't blame them if they are wrong ~ hehe). After you teach them the technology, you want to liberate yourself from management, which is not wrong. But for small businesses, technical things are not very high-tech, so some technical things still need the boss to do it himself. People who work will work until your enterprise has a scale, not to mention their quality is not very high. Even if you can teach them, it is difficult for them to be one with you. Therefore, since you decide to be a boss, you should be prepared to endure hardships and participate (it is worthwhile to be tired for yourself).
I don't know the actual situation about how to deal with it, so I can't give you a very exact solution. In short, it is indispensable to harm civil air defense. Also, pay less attention to the concept of management and think more about practical solutions to problems. If you think my answer is ok, please add me to chat on qq ~ I have encountered all your questions in my family, hehe ~ I have some experience, and we can learn from each other ~
