France varies by region
Germany reintroduced mask mandates late summer for public transport
Austria has a mask mandate for Vienna
Spain requires masks on public transport, as does Greece (where also required in pharmacies)
Other countries which still have mask mandates include Egypt, Brazil, Hong Kong, Indonesia, South Korea (and a few more) some with fines for non-compliance.
Testing regimes vary, as do requirements on those known to have covid.
Yes, we all know that sick leave is a burden, and that being off work is harder for some than others. But look at what is going on right now - people are getting bug after bug, needing time off work because they are ill, not feeling thoroughly recovered for weeks. We really should not be complacent about the mass spreading of any of the four in high circulation already.
But the government is. Despite what is going on in NHS, and that we're only at the start of the winter virus season.
And before I get shouted at (again) low covid (and everything else) is not the same as aiming for zero. And if it's low, then the need for sick leave drops, which is in everyone's interests (and that of the economy)
