My eldest daughter worked in her London based office right through the peak of the epidemic there. She did put in place quite strict distancing procedures. Some of her staff members caught the virus - were off work for a couple of weeks. Fortunately, all returned safely to work.
Therefore she was astonished and not at all happy suddenly to receive a letter a few weeks back telling her she needed to be shielded for 13 weeks. She has continued working from home throughout this, but is not a very happy bunny (to put it mildly)
The reason - thirty years ago, due to an autoimmune illness she had her spleen removed. A couple of weeks ago, she had a telephone discussion with her GP, asking if she could go to work for a couple of days a week with some strict [procedures put in place there The answer was a very firm NO.
As her employers are the NHS, there is no way they will permit her back without a GP saying it is okay.
Throughout these weeks she has continued going out early in the morning for a run, sits in her garden after work each day, did manage to get supermarket deliveries, etc.
She lives with her 17 year old daughter and does have some contact with her occasionally - but has largely spent her time by herself. She still works five days a week, long hours, but at her desk at home.
There does seem to be some sort of general assumption that all those shielding are (A) elderly and (B) not in employment.
I am certain that my daughter is not the only person who is younger (50 years old later this year) and in employment.
