More than 80 parents have complained to a school in Lancashire after cameras were installed in the toilets there.
Staff at Westhoughton High near Bolton say they need to be able to see what's going on to help them stop vandalism and smoking in the toilets.
The parents have taken their complaints right to the top and have asked the education secretary to step in.
They think the cameras are an invasion of their children's privacy and want them taken out of the toilets.
But Bolton council, who run the school, don't want to get rid of them.
Instead they want to talk to the parents to explain why they need the cameras.
