ok, dd's school: the junior teachers went on strike, the nursery teachers went on strike, the infant teachers..... No strike.
Ok, I thought, fine.
They had big posters up saying 'PLEASE ENSURE YOUR CHILD ATTENDS SCHOOL ON THURSDAY, THE INFANT SCHOOL TEACHERS WILL NOT BE STRIKING AND IF YOUR CHILD DOES NOT ATTEND YADA YADA YADA'
On picking dd up from school I asked her (as I do every day) what she had learned. She told me she hadn't learnt anything, they'd played all day 
I said 'what, no read write ink?' she said no, I said 'no maths?' she said 'no, we had all the playgrounds to ourselves though' 
Aibu in thinking that they may as well have went on strike? Or if they didn't want to then they should have at least been teaching?
I just think she could have stayed home and played, especially as they made such a big deal out of them coming in and not missing out on education.
