Biscuit0110, public services have a duty of care to Staff, so they scaled things back. Only justice work that can't be put on hold, is going ahead. You know this.
Many people decided that they would better off financially by shutting up shop. If you are declaring everything you earn, then most decided that they could manage on 80% of wages. The children were off, so they decided to do the same for a variety of reasons, including childcare/public transport issues.
Around me, essential shops are open. The hand car wash is, the florist who also sells bedding plants and now fruit and veg. The print shop is open. Until the forlough scheme was up and running restaurants were doing take out and delivery.
My gardeners and window cleaners are working, probably because they work mainly cash in hand and will get very little, if anything from the forlough scheme. Cleaning firms are still going, they are still advertising on FB. I've hired single item removal vans.
Any business that could practice social distancing was allowed to continue until we knew more about transmission. Now they are allowing two people to travel in a van together.
It was repeated over and over that if you could work from home do so, but if you couldn't then you had to consider if you could work safely. If you could, then you could work.
We have vasts amounts of people who have no recourse to public funds and are on zero hour contracts etc who needed to keep working and the government recognised this. It was either let people work or struggle with the crime rate.
