DS is 17 and has been working for a large retail firm for 4 months.
Recently he has been made to do 9-10 hours shifts to stay behind and tidy.
His contract is for 8 hours a week.
I was under the impression he was only able work 8 hour shifts due to his age.
He won't ask his boss for some reason, he's worried about losing his job. Would I be unreasonable to contact Acas/head office on his behalf? He's getting very stressed by this as he is doing A-levels as well.
