1. 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. Pay attention to your words when you ask for leave. In the tone of asking for instructions, you can say: Leader, I have something at home and I want to ask you for a day off. I hope you can approve it. I am very grateful! Instead of saying that there is something at home, I have to take a day off.
3. It is better to have a good reason for asking for leave. If your leader doesn't take those small holidays, such as traveling and playing, don't say that you need to take time off because of something at home, or you need to go to the hospital for examination if you are sick. This is a convincing reason.
