I understand the time off work thing but if you get a positive test you are spreading to your fellow co-workers and clients anyway so are just creating more problems.
But not everyone has co-workers and clients, and works inside.
I'm a dog walker. I work alone. I go into empty houses, collect the dogs and spend all day in the open air with them.
If I had symptoms and tested positive then of course I would isolate, but I'm not about to take 10 days off work (completely unpaid) when I feel absolutely fine and have zero symptoms. Sorry, but I'm not. I need to keep my business running.
