Professions returning to work.

In anticipation of the eventual easing of the lockdown, has any analysis been completed to decide on which professions can safely return to work and when ?

Clearly any that involve direct contact with the public, even on a small scale, involves risk.

Even now you could argue (for example) surveyors could work now? Minimal contact with a homeowner (similar to plumbers etc...) and even after lockdown ends they would need to take the same precautions.

I am sure there are very similar examples.

Boost the economy and help businesses prepare in advance.
