I wrote that my resignation date was May 1 day, while the real resignation date was May 13. When should it be counted?

Resignation refers to the labor legal system in which employees leave their original jobs and work units.

There are two situations: one is to take a break from work, to leave for further study, to stay without pay, and not to terminate the labor legal relationship; The other is that the employee resigns and is approved by the unit, dismissed by the unit, voluntarily resigns, and the labor legal relationship is terminated. Resigned employees enjoy different treatment according to different situations.
