I was putting out our Household rubbish and recycling last night and thought thank goodness they are still working and we don't have rubbish building up in our streets. They must have staff off self-isolating too and worry the same as we do but have to work in fairly close proximity to each other.
I decided to sellotape a note of thanks on each bin and asked them to keep safe because, although they aren't saving lives, their roles are so important. We only notice when there are strikes.
My DH saw them arrive and the operative showed the note to everyone on the vehicle including the driver and they all gave the thumbs up sign towards our house, clearly chuffed.
I think a lot of people feel unappreciated and maybe we could all show our gratitude more often.
