I wholeheartedly support the teachers' cause, but do think you are woefully let down by your unions. I've suggested to DH that he starts a new union for informed teachers who understand what the issues in education are.
Unfortunately the teaching unions seem incapable of recognising the profession has an image problem and doing something about it. They provide soundbites that Gove must dream about and trot out the weakest press releases known to man. What was that nonsense a few months' ago about the unions calling out to reduce the time teachers spent teaching? Why has no-one asked their union how they completely managed to lose the point about it being about too much PPA and challenge them on the fact that all it did was add to the perception that teachers are lazy? 
When membership is £200 a year per teacher, I'd like to know why they can't employ a press officer who can match the shite the government churns out and put together a coherent argument about why they're striking. 
And for every Daily Fail reader who bleats about 13 weeks holiday and gold-plated pensions, I think there's a teacher who's blindly following the herd and not completely understanding what they're going on strike for. I think most teachers, when sat down and really thinking about what's at stake and what they have a problem with, would be surprised at how much they've taken what the unions have told them as read without looking into it themselves.
The pensions is a good point. The changes are not great but it's clear from some of the posts on here that some people don't understand them and if that's your basis for striking, you need to understand them. Likewise the performance related pay terms. I agree it's concerning and anyone who thinks that this is a ploy to reward good teachers is misguided. But when people argue that it'll mean no-one wants to teach the bottom sets or under-achievers, I just think people have just read the headlines from the unions.
I think it's important to question both side's agenda. The government's is obvious; put less money into state education, systematically erode how much a school needs to run and provide a semi-decent education for the proles. But don't forget the teaching unions have an agenda too, and I don't believe they have DH's best interests at heart either. To support the unions you must believe they are acting for you and what you believe and I do think that involves more than just reading what they send you.
And too many people unilaterally hold Gove responsible for all that is wrong with mankind. His name's a dirty word in our house, and he's an odious little man, but it was OFQAL who did away with the English controlled assessment results. And OFQAL who has also delayed the roll-out of the new GCSEs for a year as they weren't prepared to implement something Gove had dreamt up overnight.
