Nobody wants to spread this illness but also nobody wants to face losing their job/home and leaving their children hungry. It is a solvable issue but the government/large companies aren’t willing to do anything to solve it right now.
Honestly I think you just need to inform yourself better about how viruses spread and how to manage risks.
A) A few weeks self isolation is not going to mean your children starve! Almost all jobs can be flexible if it comes down to it, and almost everyone has annual leave and sick leave, or benefits, or whatever.
B) if you those most at risk of spreading the virus do not self isolate if necessary, then many many more people, think one person = 400+ will then have to self isolate. Like in Tenerife for example.
C) Companies are being responsible. They are sending people home and allowing people to work from home if necessary, as in that London company, can’t remember the name, with pay.
D) if your primary aim is just your own safety, then not isolating is putting yourself at increased risk. Ignoring symptoms and carrying on working, and possibly giving yourself a higher viral load, when you do know that >10% need critical care in hospital don’t you? That is no picnic, you want to put your own family through that?
E) it is your own family that will be most at risk if you do not act responsibly and will be more likely to catch it from you.
