Is it illegal to tape someone without their knowledge in Tennessee?

Yes, it is illegal, and not just in Mississippi, either ... same is true for most states.

could someone expound on this scenario, I had a private conversation with an adult student, in my office and she recorded the conversation without my consent. THEN my supervisors said they deemed it legal for them to listen to it. ALL of this without my knowledge until after the fact. I felt raped. Even though they "determined" nothing incrimination or letigenous, It is the fact that students now feel they can record our private conversations and others hear them without my knowledge nor the knowldege of the issue surrounding that case,, Are they scamming me? is this illegal?
