Under the award and our EBA, you should never and legally do not have to work in the rain. However, you must make the work area safe before you cease work. If a concrete pour has commenced prior to it raining, the pour can continue until finished, but all affected workers must be provided with wet weather gear and shall be paid double time until they have completed their work. They are then allowed to go home for the remainder of the day without any loss of pay.
If it rains at/before starting time and there are no covered walkways from the amenities to the workplace, workers do not have to go to work unless the rain stops or a covered walkway is provided.
Further information can be found in the Construction and General Award (Clause 23)
