I think the length of holidays teachers get is a perk, I think it's churlish to consider it anything else.
However, that has to be counterbalanced against the hours they do in term time. And further, what do you want them to do when the kids are off? Turn up and teach an empty classroom?
I often wonder if a teacher could do more of their lesson prep in the summer holiday so they don't have to do as much in term time, but given that I've never worked as a teacher I can't know for sure.
