Good answer, sherrardk. Many people misunderstand how inset days are treated. The school year is no shorter - it's the teachers who get 5 fewer holiday days (although i realise that most will have no sympathy!)
The teachers will not be paid for the strike day and many schools will close.
I don't support the strike but I can see why teachers should be allowed to strike.
For those who think teachers have an easy life, I've spent 4 hours (unpaid) today marking work from when I did three days supply cover at a school last week. And I've just spent another hour planning work for the supply teacher who'll be covering tomorrow at that school. Right- I'm now going to plan my own lessons for tomorrow including an after-school revision class.
