Demand for staff in the financial and insurance services industry has recovered after a period of weakness last year that coincided with the Hayne royal commission.According to the latest Sunsuper Australian Job Index, job advertisements in the industry rose by 10.1 per cent for permanent positions during the March quarter, and by 19.3 per cent for "contingent" positions (temporary, contract and casual).Sunsuper chief economist Brian Parker says the big increase in advertisements for contingent jobs will be contract roles in large business transformation projects.The index is created by tracking job advertisements on digital job boards, employer career portals and recruitment company websites, using 4000 sources. It is a measure of employment demand.Job advertisements in the financial sector slumped in the June quarter last year and were flat in September quarter. Demand picked up in the December quarter and has continued this year.The industry is currently one of the strongest sectors for employment demand, according to the survey.The overall job index was down 0.4 per cent in the March quarter but up 0.3 per cent for the 12 months to the end of March.The weakest sector during the March quarter was retail and wholesale, with job ads down 4.4 per cent.
