Former executive assistant Amber Harrison's social media campaign against Seven West Media is designed to put the company under maximum pressure at its annual results briefing to investors, analysts and journalists this week.
Ms Harrison posed questions for the company and posted letters and documents on Twitter all last week, including a document that alleges she personally negotiated a severance package in 2014 with Kerry Stokes, the controlling shareholder.
The 39-year-old, who was made redundant after having an affair with married chief executive Tim Worner, wants to expose "the truth" about what she says is a cover up of a plot to get rid of her because her presence was uncomfortable for the CEO, a source familiar with her thinking said.
She wants Seven shareholders to know how much was spent on her legal and public relations dispute with the company and highlight institutionalised sexism, the source said.
Personal spending
An audit ordered by Seven found that Ms Harrison's corporate credit card had racked up tens of thousands of dollars in bills for international flights, hotels and flowers for relatives and friends.
Ms Harrison has told friends that Pacific Magazines, where she was the CEO's executive assistant, had a "fast and loose credit card environment" and that she was the only person of 4000 employees at Seven West Media investigated over use of her credit card.
Seven hasn't granted the media access to the two executives at the centre of the dispute, Mr Worner and commercial director Bruce McWilliam, since the story broke in December, when Ms Harrison emailed media outlets around the country about her 18-month affair.
The story of day-time illicit rendezvous and alleged drug use by the CEO and the attractive secretary became an instant public relations nightmare for Mr Worner and Seven West Media, which owns the Seven Network, the West Australian newspaper, Pacific Magazines and Yahoo7.
The pair weren't in a relationship and their only face-to-face contact outside of work was to have sex, Ms Harrison has said.
Legal strategy
Ms Harrison feels Seven was responsible for a legal strategy that was designed to exhaust her financially, the source said.
Releasing information each day on Twitter is designed to encourage or pressure the Seven board into acting, the source said, although what specific action Ms Harrison wants hasn't been specified. She signed up to Twitter to respond to comments by Seven director Jeff Kennett, who has been the company's prime public defender.
Last week she mentioned the only woman remaining on the Seven board following the resignation of Sheila McGregor, who stepped down for unexplained reasons after an external legal investigation effectively cleared Mr Worner.
"When Dr. Michelle Deaker & 2 others (maybe @jeff_kennett) are up for SWM Board re-elect this year – will they answer shareholders questions?" Ms Harrison tweeted.
Dr Deaker is chief executive of OneVentures, a venture capital firm based in Sydney. She founded a leading online gift voucher company, E Com Industries, and sold it in 2005.
Profit presentation
Mr Worner will have to lead the presentation of the company's results on Wednesday and will presumably be asked about the scandal by journalists, although it is unclear if analysts or investors believe the ongoing publicity will have any impact on profits.
"It will be business as normal," said a spokesman for Seven. "He will take questions from the media and will participate in the roadshow afterwards."
Seven's director of corporate affairs, Simon Francis, has been an assiduous briefer of journalists for years, although last week he referred questions about Ms Harrison to Tim Allerton, the managing director of City Pubic Relations.
Ms Harrison has shown skill at using the media too, talking to journalists off the record and requiring quotes for publication to be approved in writing.
