I worked at my previous UK secondary school for 11 years. During this time, I managed to get my (pretty work-shy, primary trained) friend a regular stint as a supply teacher. In 2017, I went abroad to teach. My friend was still called in from time to time. She is paid on MPS. Since returning home (my father has cancer and my sister is going through a breakdown), I have been in touch with my old school. They will only go through an agency (that pays £94/day before tax and holiday fund) to employ me. They still pay my friend through the county. I spoke to the Assistant Head in charge of employment/cover/whatever you want to call it, and she said that she feels bad for my friend because she has 3 children. I am lost for words. The AH is my previous HoD who I had a lot of respect for and we were actually really good friends before she was promoted about four years ago. I don't think there is anything I can do about this, but I wanted to get it off my chest and moan about it.
