Australia Post’s former boss Christine Holgate has threatened to sue the Australian Government over her departure from the company unless it agrees to mediation talks by Wednesday night. Tick tock… She says she was unlawfully stood down over the purchase of Cartier watches as a reward for senior execs and claims she was bullied by both chairman Lucio Di Bartolomeo and PM Scott Morrison. Di Bartolomeo yesterday said he was willing to enter talks but described Holgate’s deadline as “unreasonable”. As for the ministers with responsibility for AusPost, neither Paul Fletcher and Simon Birmingham are putting their hand up to attend any talks.
