How to send resignation information to the boss

Situation 1, you have submitted your resignation application to your boss: since you resigned, the salary these days is not bad. Be a man of backbone.

Situation 2: You submitted your resignation to the HR manager, but the boss didn't know it yet. Then you sent a short message to the boss according to your wishes, with the general content that you will leave at the end of the month. Life needs new goals. I don't think it is suitable to continue working in this position, and I need a change of environment. Thank the company and the boss for your cultivation. At that time, all you have to do is throw the end of the month to the boss. The boss will not bargain with you in those days.
