"I promise you no one at the school gives a shit how often your child has been off, or why, but we are told to do these things, so we do them."
I'm sorry, but certainly in primary, we care.
We care about the child who is always off on a Monday morning, especially when it turns out that they have had to get themselves up, dressed into last Friday's clothes, and grabbed a slice of plain bread for lunch, because their parents are too hung over / coming down from the weekend to get out of bed.
We care about the child who gets every bug going round, particularly because we can also see that they are uncared for and underfed.
We care about the child who is 'ill' every Friday, because their parent has a F-Sun job so they are required to stay at home to look after their 3 younger siblings.
We care about the child who is 'ill' after every visit to their non-resident parent, until such time as their bruises have faded.
We care about the 9 year old young carer who is late every day because they get the rest of the family up and dressed before catching the public bus across town to school.
We care about the child who is kept off for every sniffle, especially because they are already behind and every lesson missed they fall even further behind, and we know that their parent does not value education at all. We also care about the child who is there every day, from 45 minutes before the school opens and whatever state of health they are in, because their mum can't afford to lose their job by asking for a day off to care for a sick child.
Oh yes, we care (I have made none of the above up. I have left out the ones - fabricated illness / injury, children kept home to work) that sound as if they could have been made up but are also true....
