How to urge leaders to reply in the middle of resignation

1. Send a friendly reminder email: You can politely send an email to ask the leaders if they have received your previous email and remind them to reply as soon as possible. In the email, express your understanding of the other person's busy mood and explain the importance of your timely reply.

2. Determine the right time: If you have the opportunity to communicate face to face, you can make an appointment in advance or arrange a time period to explain to the leaders what you need them to reply and ask them to reply as soon as possible.

3. Seek other channels: If your email or verbal reminder doesn't get a response, try to contact the leader through other channels, such as telephone, SMS or instant messaging tools. But please choose the right way and respect each other's personal preferences and privacy.

4. Communicate with the Human Resources Department: If the above methods are still not answered, you can consider communicating with the Human Resources Department to seek their assistance and advice. They may be able to help you contact your leader or provide a solution.
