Most of the issue with teachers being defensive appears, to me, to come from parents whose main point of complaint appears to revolve around their own convenience - they are working people (apparently teachers are not real working people like them, so don’t understand working people), and school hours and terms do not suit working people. Working people need more free childcare - unless they are teachers, of course, because they are the ones needed to take up the slack (and aren’t really working people). The whole thing about loss of learning over the summer is interesting as an excuse, given the fact privately educated children have longer holidays and yet appear not to become so dimwitted over their vacations that they suffer in any discernible way as a result. And what is an increasing amount of time in school for, especially over a time of year getting increasingly hot due to climate change, in poorly designed, inadequately maintained buildings? Apparently it’s mainly to take up the slack in parenting and failed public services elsewhere, not in academic learning: growing numbers of children who aren’t potty trained, can’t speak clearly, have limited fine motor skills, poor nutrition, rotten teeth, obesity, low emotional intelligence, limited social skills, mental health issues, antisocial behaviour, addictions, chronic illnesses.
Teachers, it appears, are expected to get increasingly involved in the minutiae of families’ lives - to safeguard and protect, to be an alarm system for other services that are too stretched to fulfil their own functions. It is, really, a ridiculous ask. Schools should not be expected to take on the consequences of all of society’s failures elsewhere. If people want longer academic terms and shorter holidays, then they need other services to function better, first, so that schools can do what schools were originally designed to do, rather than having to devote so much time and attention to problems that should never have been left to schools to deal with in the first place. Until then, it’s really not surprising if teachers really don’t want to be confronted with all of society’s failings for even more of the year, or to have a shorter summer break to recover, and teaching no longer appears to be a particularly popular profession.
