Strangely I don't have a problem with teachers ( or anyone else who is striking ) spending the day in the pub on a strike day. They are withdrawing their labour and won't get paid so their time is exactly that - their time.
With the second point I was suggesting things such as no out of school...
In short :
Gove IS a bellend
Teachers shouldn't strike - it amazes me that parents can get fined for taking their children out of school for a short period and teachers are up in arms when they do yet it's OK for teachers to strike for a day or so.
If the teachers want to hit back then refuse...
Having worked on a farm ( admittedly not as a farmer ) I can assure you that most farmers earn their ( normally pittance ) money many times over many professions including teaching.
My ex-wife and my sister are both teachers and both are agreed that inset days should be during school holidays. Barring report time neither think they're overworked or under paid.
