"presumably the family are paying for their elderly relative's care.
It's not U in the slightest of them to want to employ someone who's actually going to do the job."
So people have to run the risk of getting lung cancer and all the other illnesses that come with passive smoking? Not to mention the stink that'll be on their clothes and hair. If you pay, does that give you the right to endanger someone's health like that?
I realise it's the ill person's home, but workers should not have to be exposed to smoke like that.
