Westpac calls up new operating model 04 November 2013 5:37PM Ian Rogers Many jobs at Westpac's contact centres will have their job descriptions updated over the next 14 months as the bank adopts a new "national operating model".The Finance Sector Union sketched out the model in a briefing for members last week.The changes affect staff working at Westpac, St George, BankSA and Bank of Melbourne customer call centres.The proposed operating model "includes a career framework, with new job families and job descriptions", the FSU wrote, based on advice from Westpac.A new career framework will be established for every employee, while each role will have a "learning plan" for the first time.The proposed operating model will be implemented over "a five-wave transition process, which will take place over approximately 14 months", the FSU said.
