It was our LA secretary Mistress.
The EIS isn't why teachers come in for criticism- it's society's view of teachers that can't stand our union advocating for us 
And that he is in an environment with his peers that enables and encourages learning - even if that is making Christmas decorations and watching the muppets. They are still learning, discussing, interacting with people not in his nuclear family, practising motor skills, learning from random stuff the teacher is chatting about while they are busy... It's not childcare to me, it's education, and it is really, really important.
This is a lovely sentiment, but who do you think pays for all those Christmas decorations? All that lovely thick paper, pom poms, glittery bits (enough for 35, because someone always mucks theirs up and someone else has to make two because mum and dad are separated)? Who bought the DVD? Who buys cakes, icing, sprinkles, juice, hot chocolate?
Teachers. We buy 70-80% of that, and it all adds up. There's always pressure to do nice things and this year there's even more, because the children have had a crap year and they're not getting to go ice skating or to see a pantomime.
If you, as parents, want this sort of activity and value it, then value your teachers.
