How to send a message to the boss when you suddenly take a leave of absence?

I have a cold and a fever, so I hereby apply for X days off. Please ask the leader/supervisor for approval. Thank you. Hereby, pay tribute! XXX .

Hello, boss! Who am I? You haven't answered many calls before, so I can only send messages. Please forgive me. I don't feel well in the morning, so I can't go to work. I need to take half a day off to go to the hospital to see a doctor. And this half-day work arrangement will be temporarily handed over to another colleague, and I have already made an appointment with her. Please approve, thank you!

Precautions for vacation:

1, sincere attitude. Be sincere when asking for leave from the leader. If you don't ask for leave in person, you'd better call the leader for leave, or you can send a text message for leave. It is best not to send WeChat or QQ on leave, which seems to be ignored.

2. Work handover is good. Before you ask for leave, you should do your own work well. If you haven't finished it yet, you should tell the leader in person or send a text message to tell which comrade you have handed over the work you are responsible for, and report the progress of the work to the leader in time when you come.
