The company informed the training, and the ems informed that it was rejected. Is the notice valid?

Effective. China's "Several Provisions on the Courier Service of Civil Litigation Documents by the Court" stipulates that the letter of refusal to inform is deemed to be served according to law, so it is still valid. Therefore, the company informed the training, and the ems notice was rejected, so the notice was valid.

The company can send training notices through internal mail, corporate WeChat and internal website. Choosing the appropriate delivery method can effectively improve the participation of employees.
