The former managing director of the ABC Michelle Guthrie has filed an unfair dismissal claim against her former employer with the Fair Work Commission.

The ABC board sacked Ms. Guthrie on 24 September, and two and a half years still to go on her $900,000 contract.  By the end of the week, the ABC had also let go chairman Justin Milne after reports surfaced alleging he had urged the then-managing director to sack two prominent reporters because the Government "hated" them.

Guthrie will argue that the board had no grounds to do this.

"While my contract permits the board to terminate my appointment without cause and with immediate effect, I believe there is no justification for the board to trigger that termination clause," Ms. Guthrie said at the time of her dismissal.  "At no point have any issues been raised with me about the transformation being undertaken, the Investing in Audiences strategy, and my effectiveness in delivering against that strategy."
