This situation is fluid and ever-changing, and I am sure everyone is receiving multiple emails about the changes in their constituencies. My right hon. Friend makes a point about the need to self-isolate. That is an essential part of any infection-control programme, and this is a public health emergency. Constituents have contacted me today to say that their employer, Amazon, is refusing to pay members of staff who have self-isolated unless they can prove that they have had a positive covid-19 test. That is forcing people to make the choice to go into work and not self-isolate. Does he agree that that is reckless behaviour on the part of Amazon?
