I'm currently working as a receptionist at a small gym. When I first started out (July 2014) my boss told me I needed to get an abn and to submit invoices in order to get paid. At that point in time I was working 12 hours a week and only getting paid for 7. For those 7 hours I was paid $20/hr which I believe is below minimum wage for a casual worker. My boss said he only paid me for those hours because I could earn a commission as well. He made it very hard to earn the sales commission and coming up with reasons why I hadn't earned it. Is this legal? My friend pointed out the other day that it seems that he is sham contracting - hiring me as a contractor instead of as an employee. I am working the same hours every week and have set tasks to complete using equipment provided by the gym. When I first started, he said that I had to get an ABN because he didn't like doing payroll and if I insisted on doing it that way instead of getting an abn then payroll tax would come out of my wages. I'm not sure what to do now as I feel that if I bring this up with him I am likely to lose my job. What steps should I be looking at taking now?
