I wasn't actually talking about secondary school teachers growstuff, my post opened with the words "primary school teachers" and I was alluding to these teachers throughout.
Primary school teachers aren't trained to be babysitters either, and I think many would take offence at that suggestion. Primary school teachers do those extra caring acts mentioned in addition to teaching, just as GagoJo spends additional hours consoling or cajoling her teenage charges. It is called going above and beyond. It might be once a month in a primary school there is a toilet accident, once a term a child pukes in the classroom, once a year there is a broken bone, once every 5 years an anaphylactic shock, but primary teachers are usually ready to deal with it when it happens because they have good practical skills.
