Detention after school. We weren't informed.

[OrmIrian]

Is that worth making a fuss about? DS#1 was trying to insist they don't have the right to give him a detention when they didn't inform us . I told him that may well be true but he was still going to do it! He 'forgot' some hw so I have no sympathy.

Should I contact the school or will I be a neurotic over-protective parent?

Yes, I believe parents must be given 24 hours notice for any detention after school (if longer than 10 mins). Break and lunchtime detentions or internal isolation can be given without notice to parents.
