Can there be smoke without fire...
"Today NUT and NASUWT members in London and the south-east will be striking in defence of their pensions, pay and conditions. Members at Christ's Hospital school fully support the demands of their colleagues in day and state schools. Ours is a boarding school, thus we will not be taking strike action. We will be contributing to a hardship fund for striking colleagues. All teachers in the Teachers' Pension Scheme, including those in independent schools, are affected by the decision of the coalition government to impose changes to our pension arrangements. The most worrying is the greatly increased length of service - up to 68 before teachers can retire on a full pension. We are fortunate to enjoy smaller class sizes and better pupil behaviour than in many state schools; however, even with these benefits, being able to teach groups of teenagers effectively in one's sixties will be challenging. Pupils stay the same age, teachers only get older (much older!).
