Some people don’t get paid based on the number of hours they work.
Piece rate employees (or pieceworkers) are paid for the amount they produce or for each task they finish. For example, they could be paid for each bucket of fruit they pick, or for each piece of clothing they make.
Commission-based employees normally get a fee or percentage based on how much they sell. This is common in the car sales and real estate industries. A commission can either make up their whole wage, or be paid as an extra incentive on top of a base wage.
Awards, agreements and the National Employment Standards have minimum pay rates and conditions for pieceworkers and commission-based employees.
