We have a young tt attached to the department (I am HOD.)
There have been a few problems since she began. I met with her today to discuss them. I was honestly lovely and gentle and positive but it all went wrong.
She just lost it, crying and interrupting me like a teenager would! Lots of 'yeah but ' and 'I need to give you my side's and claiming I had done the things she had 
I honestly have real concerns about her now where I didn't previously. I have never known an adult have a tantrum like if!
