occur[1] had not been completed at the time of the outsourcing decision. It was relevantly alleged, and found by the primary judge, that the reasons for the adverse action – the outsourcing decision – included to prevent the exercise by employees of their workplace rights in 2021, following the nominal expiry of their enterprise agreements, to: (i) organise and engage in protected industrial action[2] or a protected action ballot[3] for the purpose of supporting or advancing claims in relation to a proposed enterprise agreement; and (ii) participate in enterprise bargaining[4] under the Act.

Section 361 of the Act establishes a rebuttable presumption that the adverse action was taken for the reason alleged, or with the intent alleged, if taking action for that reason or with that intent would constitute a contravention of Pt 3-1 of the Act (which includes s 340). A person takes action for a particular reason if the reasons for the action include that reason[5]. The presumption in s 361 recognises that the decision-maker is uniquely placed to know the reasons for their action and should thus be made to prove them[6]. An employer can discharge that onus by proving that none of its substantial and operative reasons for the adverse action was to prevent the exercise of workplace rights[7].
