I am an ex teacher who now works freelance in a related industry.
A million pounds would not make me want to go on supply teaching right now. Teachers are treated abysmally. Supply teachers are treated even worse, by agencies and by the schools they teach in.
I stopped doing supply teaching alongside my freelance work when the first lockdown happened and it was clear that schools were unsafe and nothing was being done to rectify this.
Why on earth would I go into school (into a classroom where the teacher is probably off having caught COVID from the students) for less than I was paid as a contracted teacher and risk getting Covid, only to then be off work (completely unpaid) for the time it took me to get better? I would also probably have to take unpaid time off my freelance work if I was ill.
The government are completely out of touch with the reality in schools and genuinely do not care about the safety of staff.
