FSU national secretary Julia Angrisano has consolidated her power base within the union after beating off a challenge for her position from Victorian-based NAB employee, Nick Perna.While the Australian Electoral Commission is yet to make an official declaration of the election outcome, scrutineer reports from counting conducted last Friday indicate that Angrisano won around 80 per cent support from FSU members who voted.Angrisano supporters have also claimed a string of other key leadership positions in the union, including the national presidency, which saw the incumbent Louise Arnfield lose her post.The union's new national president is Bank SA staff member, Johanna Tran, who openly tied her campaign to Angrisano's re-election.Arnfield's departure will remove a source of tension within the union's leadership, which has been riven by conflict since the resignation in 2016 of the previous national secretary, Fiona Jordan.Perna made no secret of his support for Jordan and promised to "continue the work" she started.Perna-backed candidates lost most of the state leadership ballots, including vigorous contests for local secretary positions in Queensland and South Australia.However the trend was broken in Perna's home state of Victoria where ANZ technology worker David Scanlon was elected state secretary.Scanlon has deep experience in information technology at ANZ and in a previous job at NAB.He also has a long resume of voluntary community service that included running for the Senate on behalf of the Voluntary Euthanasia Party at the 2016 federal election.In the union election, Scanlon ran as a reform candidate under the slogan of "Let's build a better union!"In a phone conversation with Banking Day on Monday Scanlon declined to comment on the aspects of the union's operation he wanted to see change.?"I'm looking forward to working with all officers of the FSU," he said."I see my election win as a win for members - it's going to be a steep learning curve for me."On his campaign website Scanlon says he was giving the union "one last chance" to improve the way it communicates with members."I am still very disgruntled and believe that the union can improve significantly in the way it operates, communicates and consults," he says on the website. "And that is why I am giving the union one last chance…"In a press release issued on Monday, Angrisano congratulated Scanlon on his win and highlighted the importance of restoring public trust in the finance sector."As a union leader, my first priority will always be to secure better wages and conditions for our members," she said."However, consumers also deserve a finance sector that is reliable and trustworthy. "As a part of restoring trust in the sector, I will support finance sector CEO's who are doing the right thing by their employees and their customers."Former NSW premier and Angrisano supporter Nathan Rees was re-elected unopposed as deputy national secretary of the union.
