I think you should make it clear with your own subjectivity when you leave your job. Needless to say, it is so straightforward. After all, you were poached, and you didn't resign on your own initiative, so I think it's necessary to save face for each other.

Many people will face being poached after working in the company for a period of time. This is normal, but it is a big problem whether being poached can truly reflect your own value. On the one hand, being poached proves that you are very good. On the other hand, I think being poached also proves that you have strong communication skills. In this case, you should have a good talk with your boss when you resign. It's best not to mention poaching, because it will embarrass both of them. After all, there are many people who have been poached but have never chosen to change jobs. Their existence will make many people feel embarrassed.

Besides, I think you should keep in touch with your former boss after being poached. After all, it takes a long time to see the benefits of personal relationships. If you have good connections, you can get to know a big boss, so that you can provide financial support when you want to change jobs in the future.

To sum up, when you resign from your boss, I still hope everyone can talk to your boss with a humble attitude. Modesty is not a bad thing, it can make others think that you are a very sensible person, and it is also a good thing to leave room between two people. No one knows whether the boss will dig you back with better treatment in the future.
