How to query the resignation progress?

Hello, friend, the progress of resignation. Under normal circumstances, if we leave, we will directly submit the application for resignation, and we can go through the handover procedures after 30 days. As for whether the leadership approves or not? In fact, there are not many labor laws. As long as the enterprise is notified of the expiration of the resignation information 30 days in advance, it can go through the resignation handover procedures, and the enterprise must pay the salary in full.
