We were told to WFH (since 13th March). The business has continued uninterrupted. Only a very small part, say 50 out of 20,000 employees are 'key' workers but we have all kept working.
We would have paid our long term cleaner whether she came or not, we have been her only client for some time. She has visited us throughout. We go out for a walk / into the garden / keep out of her way while she is here, but we do that regardless of any new virus.
As PP have said, people have been 'allowed' to go to work if they have not been able to WFH.
Lots of businesses which you might think of as closed, such as airlines are still doing cargo flights and processing people's refunds.
If everything had closed, life would have been a lot harder, no deliveries or utilities.
Funny how people understand things differently, even after only a couple of weeks.
