Australian casino operator Crown Resorts faces a lawsuit from a former first aid manager concerning her alleged unlawful dismissal and the company’s failure to adhere to health and safety regulations.

Ms Gatt was fired after five months of working for the operator, as she claims her persistent occupational Health and safety (OHS) complaints, of which there had been more than 20, were the real reason for her dismissal.

The worse alleged OHS offences included being told to “ignore” a domestic violence case at the hotel and a chef being unable to receive first aid for a burn until the end of his shift.

Australian news outlet The Australian Financial Review reported that her employment at Crown was terminated in April, a week before a WorkSafe audit. She says she was told she was being dismissed for unsatisfactory performance. Ms Gatt's lawyer, Trent Hancock at employment law firm McDonald Murholme, argues she was unlawfully dismissed because of the volume of her complaints. Ms Gatt wants compensation for losing her job and a maximum pecuniary penalty, which is currently set at $63,000.

Crown Resorts have failed to yet comment on the case as it is still going through the court proceeding.
