01 William is a delivery van driver for Deliman. William uses his own van and usually gets paid $900 per week net. He usually works 38 hours each week, largely made up of 8am - 4pm shifts. He gets no annual leave or sick pay. On commencing work with Deliman, William signed a pre-printed form headed 'Conditions of Contract'. It stated that van drivers agreed to be contractors and not employees. It also stated that they must observe the standard of client service outlined in the "Deliman Workers' Manual\". Recently, William's boss told him that Deliman no longer required his services. The boss added that he did not need to give William any notice since he was \"just a contractor\". Is William's boss right about him being a contractor rather than an employee? Why or why not? (27 marks)
