I guess my home does not count as public place (despite the comings and goings at the moment!) but it is a workplace atm owing to the fact that we are having an extension built.
Before the roof went on, I had no objections to the builders smoking. When they were indoors but in the extension, I was somewhat miffed when their smoke permeated through walls and doors into the main part of the house. But today, the wall between the main house and the extension was knocked down and now the whole of my house is slowly filling with the smell of cigarette smoke.
I am too much of a wuss to complain and tell them not to smoke, but I wondered what the legal position was since the smoking in workplaces ban came into effect.
