See Fair Work Act ss.725‒733
When a person is dismissed, it may be necessary to choose one of several available options for challenging the dismissal (apart from a general protections application there could for example, be a right to make an unfair dismissal application or a claim under anti-discrimination laws).
The Fair Work Act 2009 contains provisions which allow only one application to be made (a single action) in relation to a dismissal. Multiple actions for the same conduct are not permitted.[1]
