Am I missing something here? If you are in a primary school then surely you can expect to be placed anywhere across the school? If there are certain year groups you 'hate' then you need to ask yourself if you're in the right phase of teaching. Also, in today's climate, I can't believe you'd just look to jump schools to avoid a year group when the same thing could happen there. What would you do, keep shipping out until you got guarantees about the year group you wanted? For the record I am the head of a large primary and I told my staff they were staying put in February because we have inspection in the Autumn but I have also told them I will be making changes, in consultation with them, at the end of the next academic year and I will tell them as soon as I have finalised the budget and other organisational matters which will probably be early May and no later. It's not good for the children either to have their teacher with one eye on next year before this one is over.
