Although I'm a member of both the NASUWT & ATL unions, I technically can't strike as I don't have a job at present, and although I have been invited by both unions to join in the demonstrations, I won't be rallying/protesting either as I have my 2 small children to look after. However I am fully behind the strikes.
Here's some info for those of you who aren't UK based and would like an overview of the situation...
