Acting Health Services Union (HSU) National President Chris Brown is studying the filing of 10 charges in a bid to oust whistleblower and HSU National Secretary Kathy Jackson.

Among the charges to be filed in the coming weeks are gross misconduct, neglect of duty and breach of rules. Victoria HSU member Daniel Govan has filed separate charges against Ms Jackson in April.

Other charges include lack of HSU authorisation to spend $40,000 used as legal fees in the Fair Work Australia probe into the union, failure to fulfill duties as national secretary and the employment of Rob Elliot, a friend, despite the lack of HSU executive approval.

Mr Elliot was supposed to be paid between $650,000 and $950,000, and his contract was allegedly kept secret from the HSU national executive and national council. Mr Brown added there was no application process involved in the hiring of Mr Elliot.

Mr Brown said on Monday that it is necessary to oust Ms Jackson from her post to restore members' confidence in HSU and its officials. She was instrumental in the filing of charges against former HSU official and current independent MP Craig Thomson whom she alleged spent union funds for personal use, including services of sex workers.

The charges against Mr Thompson, still undergoing investigation, led to a deeper probe into HSU and the eventual replacement of top union officials.

"We need someone who will put the interest of all members of the HSU ahead of their own interest and ambitions," The Australian quoted Mr Brown.

Mr Thomson, who blamed Ms Jackson for railroading charges against him which led to his ouster from the Labor Party, denied the accusation. Ms Jackson made similar claims and insisted those are fabrications. She said she will defend herself against the accusations.

"He's been sitting on those charges since April. He's done nothing about it," Ms Jackson told ANC and accused the acting national president of using the filing of charges for his personal purposes.
