The boys who are likely to behave in a reprehensible manner are those who come from a background rife with misogyny.
Before any more assumptions are made, in most cases in my teaching career, they were white and had male figures (sometimes present, sometimes absent) who were abusive towards their mothers. The boys in turn were abusive towards their mothers and their female teachers.
Some were Scottish, a few were English. A handful did come from minority backgrounds, but most did not.
I gave up my permanent post in my late 50s and returned when my husband died. I did my last supply stint over a year ago.
I was supposedly covering two days a week to help out until two new teachers arrived. The behavioural problems in the school had made the local press.
I was hit twice in one week. The first time, a boy ran into my class screaming for help at the end of a lesson. (He wasn't one of mine.) Short version - I had to get his attacker in a bear hug and walk him out the door whilst his victim cowered in a corner. I stood guard over the victim until back-up finally arrived.
It turned out that this wasn't the first time the victim had been attacked: the school simply hadn't dealt with it.
The other time, a quiet boy who had been subjected to bullying exploded. I'd put in referrals about the matter. Nothing had been done.
I could see that things were about to kick off and motioned the bully away. Unfortunately for me, the punch intended for the bully landed on my hand. (Could have been much worse.)
When the two new teachers arrived, one of them was super. Immediately engaged with one of the 'difficult' classes that I'd been working with. The kids were obviously relieved to get their 'own' teacher again.
The other permanent teacher arrived, making much of her experience and - in conversation with me was patronising, to say the least. (Of course, she wasn't to know how long I'd been teaching and managing in 'tough' schools.)
One week later, she had convinced the acting Head of Department that her 'difficult' class should be moved back onto my timetable the two days that I was in. The kids informed me.
When I complained about the lack of professionalism, the HoD blamed the class teacher; the class teacher blamed the HoD.
I declined and quit.
I figured that if the only folk willing to set a standard was one of the new teachers and a lowly supply teacher, then there was every chance of being hurt again - and I don't like being taken advantage of. (This 'difficult' department had been getting hold of my timetable and - without the cover manager's permission - had allocated my non-contacts to them, I found out.)
There were two departments in the school where discipline was pretty good, and they were both led by women who backed their teachers and whose teachers backed them. Unfortunately, I hardly got to work in those departments because the one where they had problems kept asking for me.
Yes, the SLT was weak.
I'm sick of the assumption that supply teachers having difficulty must be lacking in skill.
