I'm an a level (relevant as my subject isn't a gcse subject, I'm only with the older students) teacher in secondary and obviously some of us are concerned about going back in three weeks.
Leaving aside the whole issue of child to adult transmission, I'm worried about transmission from colleagues. I've seen lots of photos on social media of colleagues visiting multiple other people's houses, weekend visits to stay with friends and now a picture of a colleague and their family at the airport flying to a country which is not on the list of ones for exemption from self isolation on return.
