After 19 years teaching i have left my job and moved out of london. I am setting up my own business with my husband. However i decided to take a part time job teaching a mixed class of Y1 & 2. The head offered me the job straight away and we have just got down to the nitty gritty of pay. He says the salary is M2. I was on U3. Do i have any room to negotiate here? Would it be crazy to take such a drop in pay? Any advice gratefully received.
