School Detention - Fair?

[WhiteLily1]

My DS age 11 (y7) was in a lesson last week where one pupil was answering the teacher back and two other boys were chatting. The teacher gave the whole class a break time detention for Monday of the following week. DS had not done anything - he said he had been totally silent during the lesson but everyone had the detention.
My DS forgot to go to the detention- it wasn’t on his mind 4 days later, he just totally forgot. He went to apologise to the teacher In question and she gave him a hall lunch time detention for the next day. That involves being escorted to the hall at the start of lunch and sitting on a chair staring at nothing - not allowed to do anything except eat a packed lunch until the end of lunch break.
Unfortunately this was also the day of lunchtime football club which is pretty much all DS looks forward to at school.
For background, DS doesn’t get in trouble at school - his parents evening was good, behaves in class, participates etc. He has had 1 lunch detention before as he forgot his school diary. But that’s it.
I just feel it’s really unfair to give the whole class a collective punishment. Then to double down on that and for DS to miss a whole lunch doing nothing except stare at a wall when the one thing he is passionate about is on. He is really down about it.
AIBU?

No - my kids don’t have anxiety because I’ve taught them to take things in their stride. Sure, it’s a mad system, but it’s not a big deal. They both kicked off about it - and then got on with their lives.

@WhiteLily1 Have you spoken to the teacher yet?

I'm 100% with the school

When I was at school many blue moons ago - we had class detention twice - the teacher was right as most of us were stupidly silly - it was also a lesson for those that followed the two leading class clowns if they misbehaved and you lol at their clowning, you all get it. It did not work so a few weeks later the whole class was linned up for canning - the 2/3 clowns were the first in and two cried like babies and trust me it drover the crap back up me as we waited in-line outside the dep heads office - it did the trick class was much better behaved and the 2/3 clowns, one got expelled, one took to missing lessons and the others mellowed

Blimey - sounds awful 😭

I haven’t, my son seemed to go in to school ok this morning so I think I am not going to blow it up this time, hope it’s a one off. However, if any more class detentions are given out, I will be emailing in and finding out the policy on this.
Thank you for all the replies- really useful and have given me pause for thought and words to use should I need to write in

It did the trick

Collective punishments are a wonderful idea if the goal is to lose the respect of the previously well behaved students and encourage them to be defiant. It has the added bonus of alienating parents, making it much harder to get their support if you need it later on.

My DDs went to pretty strict school and none of these would have earned then a detention. The school should have their behaviour policy on their website which should ideally have some sort of chart of the sanctionable behaviour and the corresponding sanctions. It might be worth looking at that. If it’s not on the website, email the school to ask for a copy.
