I wonder how this should help while people still need to go to work in factories or large space offices. A friend of mine posted a pic of a sign in the lunchroom at Siemens that demands people to keep their distance to eachother while eating. In the meantime two or more people work together at a workbench, sharing tools, etc. But I guess every small bit helps somewhat. I am glad that the client I currently work for closed all offices and sent all people to ull remote work two weeks ago.
