As expected, a lot said but not very much detail. But with a population (and to a large extent government) which is becoming increasingly jumpy and is only just realising that life is not as certain as we all thought it was, I don't see how they could have given any more detail. So I think the adaptive/reactive approach they seem to be taking is quite sensible.
Regarding returning to work if you can't work from home, I think this is quite sensible. If we can't reopen factories/labs/garages etc. without a rise in cases, there is no hope for any of the other changes - workplaces need to open first, both as a test, and as the means to provide our livelihoods. We need to get these places open, and if there is a rise in cases then the government will have to make the choice between the short term view (lockdown again, short term saving lives, long term obliteration of the economy), or the long term view (try and minimise deaths as far as possible without worsening our catastrophic economic decline).
