What is happening, or failing to happen, that is causing the trouble?

The supervisee is not aware of the hierarchy of communication methods.

The supervisee does not know the rules for communicating with the supervisor and the supervisor is not providing direct feedback.
How might the supervisor go about improving this situation?

The supervisor should review the hierarchy of communication methods and give examples and non examples for each mode of communication.

Provide clear rules for communicating and include many examples, then provide immediate feedback that is direct when an unnecessary text is sent in the future.
