IMO Jollymum, teachers know very little about children as a whole. Unfortunately there is little control at schools now. I believe that some teachers fear the lack of power to some less respectful children and they tend to aim their power that they are allowed to hold, at others who can give them the reaction they need to uphold the respect they think they deserve.
I am sorry this has happened to your boys. This is not what being at school is all about. This is teaching the children fear and miscomprehension of being part of a safe and secure institution.
We all need a little reminding of respect and sometimes we get it wrong with some people. I would have thought that these teachers would be grown up enough to apologise when they knew they were wrong but it seems to be that they are so embarrassed that they cannot. You getting angry will add fuel to their fire. They can then use that as their justification.
I would be angry, believe me... I would.
I truly think that teachers have lost the respect for pupils (not all, I am sure) and how can that teach any child how to respect others? Your son's right to explain has been taken away. There is no respect for him from these teachers. Surely this is not right?
Power is a dangerous thing if abused. I think that is what is happening here with your son. This fear that is being used against him is not right and I reckn that this should be dealt with sensitively.
Is there a governing body you can speak to - or the educational authority?
{{{Hugs to you all}}} this is not a nice time for any of you. Keep your dignity with the school tho otherwise it will be used against you and your family... (BM has a trait of doing this - and has reputation).
Have you tried talking on a level with your son as to how this came about?
Good luck hun, I am sure that it will soon sort itself out and blow over. I have a few stories of schools that will make your hair curl, but that's for another time. {{Hugs}}
