NSW health has two lists, one for “isolate and get tested immediately”, and one for “monitor symptoms”. I know some people working casually in aged care, if they visit ANYWHERE that has had a Covid case, they have to isolate for 14 days, and because they are casual that’s two weeks unpaid.
Say you have a household reliant on a single casual wage. What percentage of workers are going to do the right thing after they’ve lost a few weeks pay?
