My local baker's who have been open throughout, who after lockdown was announced started local deliveries each day for those shielding, sold eggs, flour, sugar, butter when the supermarkets we're stripped bare, sells utterly delicious cakes and scones and always has a smile and a kind word for everyone coming into the shop (one at once only!).
Care home workers. Yes, I know NHS staff have had to deal with similar illness/death rates but care home workers are losing people they know, not just patients. It's their community that is grieving. And they're paid a fraction of what nurses and doctors are paid.
School staff (ooh, controversial!). I cannot praise highly enough the staff in my children's schools and how they have made a difference to our family. It's not just what they have done in this crisis (which has been above and beyond), but also about what they did before that enabled my children to be confident and take charge of their own learning, to be disciplined and keep to their routines, and allow me and DH to wfh full time.
