I think the link to domestic abuse is interesting. If a woman was goaded and abused by her husband for years, then snapped and clobbered him around the head with a dumbell I think the verdict and the public reaction would be the same. Which seems fair to me.
It isn't a question of him choosing to be there and he souldn't have been if he couldn't do the job...the system doesn't work that way. By the sounds of things (and interpreting through my knowledge of the system) he was signed off for however long. Occupational health get involved after a certain period, and depending on the school and how long the person has been off for a phased return is arranged. If the teacher doesn't agree to this, they can be effectivel sacked. From what we know, he told them that he thought he might hurt someone if sent back in.
As much as I hate to say it as a teacher, there geniunely are some kids who are pretty much uncontrollable. In my first year at my current school I have had the following happen:
Told to fuck off (multiple on a daily basis)
- Called a c*1t
- Pushed
- Fronted up to
- Pinned against a wall
- Chairs thrown at me
- Physically threatened
- Disgusting sexual references made to me
- Told I am bang up for it and that if we weren't in the classroom I wouldn't have a choice in the matter.
- Tried to explain to an 11 yr old why kicking in the door of the local 'paki' shop at 1130pm on a school night whilst shouting abuse will get you arrested, justifiably... to no avail.
And many more. I am a calm person and don't really get wound up by much. But even I have felt the red mist and had to walk away...imagine having a 6 foot odd teenager getting so close to your face you can feel his breath telling you to fuck off while smirking and all his mates laughing...on a regular basis. And knowing, as he does that there is diddly you can do about it. You can make permanent notes on his record, call 'behaviour mentors' (basically bouncers with VHFs) to remove him, send him the The Unit for a week, perhaps call his parents (who will either not be there or not care) and hope that they will let you have him for an after school detention. Chances are they won't, and in fact they'll swear at you too. Or you try going to the senior leadership team, who tell you that perhaps you need to work on your 'behaviour management' and that it is your job to deal with it. He'll still be in your class, and will carry on as normal, doing whatever he wants.
I'm not saying I think violence is ever the solution, but I do have sympathy for him absolutely. And I think until any of us have been in that postion and seen what some of these children can be like (and trust me, I am as bleeding heart as they get pretty much and try to see the best in/have sympathy for most of the children I come across regardless of their behaviour as there are reasons) we can't just say that he deserved to be locked up and shouldn't have been doing the job if he couldn't handle it. With all due respect, until you have tried it you really can't judge.
