In emotional testimony on Thursday, the public servant — whose identity is suppressed — detailed a pattern of intimidation she says she endured from Construction, Forestry, Maritime, Mining and Energy Union (CFMEU) officials while working in a senior role.
She told the inquiry that union representatives repeatedly made comments that suggested they were monitoring her movements outside of work. On one occasion, officials referenced where her daughter attended school, leaving the mother deeply shaken.
"It was disturbing, creepy, and inexcusable," she said. "They knew where my child went to school. They made comments about it in front of me."
The woman, who served as a former transport boss, said the harassment extended beyond professional boundaries and into her personal life, with comments about her children becoming a regular feature of interactions with union figures.
Her evidence comes as the inquiry investigates allegations of misconduct, intimidation and undue influence by the CFMEU within Queensland's infrastructure and transport sectors. The union has previously denied any systemic wrongdoing, though individual cases of aggressive behaviour have been aired during the hearings.
A CFMEU spokesperson declined to comment on the specific allegations while the inquiry is ongoing but reiterated the union's position that it operates within the bounds of industrial law and rejects unlawful intimidation.
Opposition politicians seized on the testimony, with Shadow Transport Minister Steve Minnikin calling the revelations "deeply concerning" and demanding stronger protections for public servants. "No worker should be followed or have their children targeted simply for doing their job," he said.
The inquiry continues to hear evidence from current and former officials, with further witnesses expected in the coming weeks.
