[Notice] Email, Instant-messenger integration.

We understand that some problems have arisen at work due to missed or delayed communication.

We continue to recommend using offical internal email as your default for records and smooth communication.

In addition, based on discussions on usability in various aspects of the in-house messenger integration, we recommend using it as a messenger applied to the in-house system.

The use of in-house Slack is no longer recommended.

Also, please refrain from sharing company documents and data through personal email, personal txt, or messenger.

Although sharing of data and documents is prohibited, we would like to remind you that you are still free to use it for contact and emergency communication, so please refer to it in your work.
