It makes me think people might be a bit daft when they talk about pupils and teachers as if they are the same.
When I was a child, if my parents took me out of school without the permission of the Head, the absence would be unauthorised. Nowadays if you do this and they know it is for a holiday or similar, they can fine you £60.
As a teacher, I have a contract of employment setting out my working time and holidays. But the Head, my employer, can use his/her discretion to grant me unpaid leave for occasions like funerals and weddings. But if I don't get that leave and if I decide to go anyway, staying that I am entitled to 'family time', I won't be fined £60, I'll be fired.
Teachers and pupils aren't the same.
