The boss instructed you to change your boss, what would you choose?
This phenomenon should not be uncommon in the workplace. You have made great progress, and your boss has been standing still. Of course, the boss will be impatient. Doing business is not charity. From the boss's standpoint, you will definitely try to replace your boss. You don't have to pay two salaries for what you can do by yourself. As you, maybe you have been with your boss for several years and have some feelings for your colleagues. If your boss is narrow-minded, you may not be able to do it long ago. As your boss, you may not be trained, but you have been allowed to play in your own department, and now you have to be replaced, which will be a little unwilling.
