Dilemma. I spent hours and hours helping someone prep for interview to a post at my grade and provided vast amounts of information to them. She would almost certainly not gave been offered the post without my help as she really hadn't got a clue. They came back from interview and (happily) told me they'd presented a piece of work I'd done a year ago as their own work - got major interview brownie points due to it. Do I tell? If I tell - I am stuck working with her indefinitely and she will know i told. If not, she takes up position due to a lie.
