For all their faults my smaller company is very forward thinking on this. They have banned all non-essential visits to sites by clients or contractors, and travel between offices by staff - even within the same metro area. So you can't just pop into the other office on Friday if you feel like it.

You're also asked to work from home for a while if any travelling family member from overseas visits, and if you have no reason to be in the office they won't say no if you just want to work at home and avoid public transport.

Hoping it doesn't cause a big hit to productivity because it's the right thing to do.
