I'm a teacher and I agree that incompetent teachers should be sacked - who wants a crap teacher/colleague? However, as other people have said there are some schools where the senior management bully their underlings (I'm in one now) and you have to be extremely careful - if you publicly disagree with one of their diktats they will make your life so miserable that you are forced out.
The question is, where do these terrible teachers come from? Why aren't they weeded out before they get a job? The answer is the training establishments. I used to be a mentor for trainee teachers and my goodness some of the students I had to mentor were awful. Two in particular stood out - they were on a course that enabled them to do a foundation course, get a degree AND a teaching qualification in only 3 years. I was
! Neither of them had a relevant A-level (and I'm a secondary science teacher, it's not like you can bluff it - you either understand it or you don't) and you only had to talk to them for 5 minutes to realise that they shouldn't really have been accepted onto the course. After 9 weeks of being patient, coping with their total lack of subject knowledge, inadequate social skills, poor personal hygiene and snooping, I failed them on their placement. I didn't enjoy doing this but they failed my inner test of 'Would I want this person let lose on my own children?' I wasn't personally prejudiced btw, they had two other teachers observe them who concurred with my assessment.
Next thing I know they're doing another placement, have somehow passed and are now looking for jobs. Scary stuff. I suspect that like everyone else in education, the training colleges can't be seen to fail and so pass terrible candidates.
I love the idea of Gove being forced to do a PGCE! He genuinely seems to despise all teachers so it would be interesting to see him try to cope with 30 arsey, lazy, low ability pupils. Would he manage good or outstanding every lesson? When he's had no break because he's had to supervise detention, hasn't been to the loo in 4 hours, has had a child give them some horrible verbal abuse yet not been backed up by senior management and just broken up a fist fight? I rather suspect he'd run away and hide instead...
