While I appreciate how difficult dealing with this situation is, the government have been frustratingly inconsistent at times:
People who are not in essential services should stay at home.
Let's cut public transport to encourage people to stay at home.
Only essential workers who can't work from home should use public transport.
Wait a minute - why are people still packing out the tubes? They should be running a full service to prevent this from happening.
People who can't work from home and are not essential workers can still go to work if their office can practice social distancing.
WTF?!
I am a field technician involved in customer facing services. We have been given the green light by Department of Homeland Security (fwiw) to provide communication services as essential. I suppose there is some additional risk involved but an $8 per hour pay bump above my hourly for a few pay periods convinced me. Just follow CDC guidelines and minimize your social contacts and you should be fine. But sadly, no live concerts or large gatherings until further notice! Carry on.
