I know this question has been asked a million times and I'm sure in my mind I know the answer to my own question, but I work from home in high pressured job. Single mum to one child, for 8 weeks we have seen grandparents through window and at a distance, now work is getting busier finding my patience very thin(as everyone else is) as I can't do it all, all day. Her GM has continuously asked to have her few hours once a week while I'm working for the day, now for all this time I've said no, but now considering it as we have recently had a meal with them in their garden, just not in the house. No parties have had any symptoms etc I've been tested for my job purposes in case I need to go into work and negative results.
GF is still working full time in stockroom in a warehouse, but is following guidelines daily etc. When dd goes to their house he wouldn't be there just GM who doesn't work and doesn't have contact with anyone else. I'm seriously considering it but I understand you are not allowed but for MH reasons I feel it's good for us all over other risks.
