I have been teaching full time for over 6 years now and for all of that time I have mainly been employed (with some self employment / private teaching, too). This week I have found out that my local authority is to cease ono-to-one and small group tuition in favour of whole class teaching in the new academic year and unfortunately that means as of September I will no longer be working for them; I will probably continue teaching on a self-employed basis. It seems apparent to me that I should become a member of a union which can offer the support of public liability and much more. But which one? Any thoughts on the matter would be most appreciated, thank you.
