General leaders should not take the initiative to talk to leaders about their work after work. However, if it is an emergency, it must be handled on the same day and can only disturb the leadership.
After the leader arranges all the work, he signs the note. Whether to ask for leave or not depends on whether the workload is relatively heavy. If the workload is heavy and you are too busy to take time off, it is not looking for training. You can ask for leave during the break after lunch.
