"The class action claim against WorkPac, filed in the Federal Court yesterday on behalf of CFMMEU members, demonstrates the need for legislative change to define a 'casual employee' in the Fair Work Act. It is blatantly unfair for an employee who has been engaged as a casual and paid as a casual to claim years of backpay for annual leave entitlements. Everyone knows that casual loadings are paid in lieu of annual leave," Australian Industry Group Chief Executive, Innes Willox, said today.
