Hi Izzi, So sorry you're having to go through this as I know what a pain it is. I quoted from the NEU to my agency and they gave me a number similar to 232 which like you, was below my current daily rate. They told me this number was because they offered tutoring and nursery work (even though they'd never told me this or offered me any!!) during the holidays so technically I could work in the school holidays! This bugged me because I think legally the pay should be for the school placement only and nothing else but I had already finished at the school and I'd only worked a few days over the 12 weeks and they ended up paying me the 100 odd they owed me in the end. The union actually weren't much help with me and they might say that because you've already agreed a rate and carried on, you aren't entitled. I'd still push for it with them and if you want to continue in September I'd agree a higher rate asap. It really is naughty of the agencies because I don't think they tell the schools that a supply teacher will be more expensive after 12 weeks and they ask the school to pay more and often don't take the cut themselves. Good luck with it!
