The waitress who had her ponytail pulled repeatedly by Prime Minister John Key is considering legal action.
Unite Union said this afternoon that it had agreed to represent Amanda Bailey.
The 26 year-old waitress approached the union after she was named as the author of an anonymous post on the Daily Blog last week, in which she detailed harassment by Mr Key.
"Unite will be advising Amanda on employment issues and assisting to resolve concerns about how her identity was revealed by the New Zealand Herald," the union said in a statement.
Asked whether the discussions could lead to a formal complaint or legal action, Unite Union member Shanna Reeder said: "Potentially. There are a lot of options that people have put out there. So what we're trying to do is help her decide what is the best course of action."
