When asking your manager to have a conversation via instant messaging (IM), it's essential to be polite and professional. Here's a formal way to make the request:
Subject: Request for an Instant Messaging Conversation
Dear [Manager's Name],
I hope this email finds you well. I am writing to request a brief conversation to discuss [mention the topic or reason you want to talk about]. Considering your busy schedule and to ensure effective communication, I was wondering if we could have this conversation via instant messaging (IM) at a mutually convenient time.
IM would allow us to have a real-time exchange without the need for a dedicated meeting, and I believe it would help in addressing the matter efficiently.
Please let me know if this arrangement would be acceptable to you, and if so, please suggest a suitable time for the IM conversation. I'm open to adjusting my schedule to accommodate your availability.
Thank you for considering my request, and I'm looking forward to speaking with you.
Sincerely, [Your Name]
Note: In some organizations, the use of instant messaging may already be a common practice, and managers might prefer it for quick discussions. However, if your workplace typically relies on email or formal meetings, it's essential to make a respectful request to use instant messaging as an alternative means of communication.
