Leo Varadkar (Dublin West, Fine Gael) | Oireachtas source

It is a matter of opinion but my opinion is that nobody should be shouted at, shouted down or shouted over in their workplace. It constitutes workplace bullying in pretty much any other scenario and when the Deputy does it, he should apologise for it. Perhaps he does not think so and perhaps the Leas-Cheann Comhairle does not think so but I do. The standards we uphold in this House are what people follow and if the Deputy behaves in the way he does in a workplace, he sends a signal to other people that it is okay for them to behave in that way. I do not think he should do that and we will come back to this another time.
