Maintenance and trades staff who work in the bowels of Parliament House to keep the huge building operating will enter a period of protected industrial action from Thursday in a move which could disrupt future sitting days.
Both Houses will be sitting for three weeks from February 26 and in the absence of maintenance staff in the building either as a result of a planned stoppage or rolling industrial action, any failures with equipment would need to be fixed by emergency "outside" contractors which are not always readily available, nor know the building's eccentricities.
