I can't. Should I call or send a text message when I ask for leave from my leader?

For example, make a phone call: the communication content is as follows. The leader is sorry for what I have done (describe the reasons and explain the reasons for leave, and if there is any work in progress, make clear the specific work arrangement and handover person), and finally ask the leader if he agrees!

If no one answers the phone: send a WeChat to explain the above content at the first time and ask if you agree!

Precautions for vacation:

If you expect to ask for leave early, ask for leave in advance and try not to delay the normal work of the leader.

If you expect to ask for leave a week ago, and you happen to have an important project at hand, ask the leader for instructions early so as not to delay the operation of the unit. In addition, if you know that you are going to ask for leave later and there are any important and urgent projects, you should also make it clear to the leader so that the leader can arrange others to do better from the beginning.
