What you seem to want to discuss is a totally different case. One where the authorities don't think there's sufficient risk to isolate anyone, but the company shuts down the office anyway. Correct? Correct. I'm surprised there was any confusion. Google is well placed to shut down an office with little cost, if it were a manufacturing plant it may be a different situation since telling everyone to work from home means that no work gets done. But Google is well equipped to support teleworkers, so there's little cost to them. The authorities are still learning about the disease so even if something is deemed low risk today, it may be determined to have been a much higher risk tomorrow.
