I think it depends on the stance of your employer. I am working from home and have been since 10th March since my employer considers that diabetes makes me more vulnerable - ie. I get the flu vaccine, which was all the advice available back then. Almost the entire workforce is currently WFH, and we have already been told that a mass return to work is unlikely before the end of August, whatever the govt says.
What my status will be then I don’t know, but given that my employer seems to be quite cautious I am not expecting to be in the first wave to return.
Of course, things are still very dynamic and all plans are subject to change along the way!
