I also work in a profession with such families- yes it is seeming more common but personally though, i agree that you can't force an older child to be somewhere they don't want to be....all you can do is try and encourage them to stick with it to get the grades they need to go on to do something more exciting (not that everyone is successful through that route) Ultimately, all kids are different....some who love academic learning will fly, others just aren't academic and school is not set up enough for practical hands on learning (especially high school)
I was a teenager at school in the early 2000's....I was generally a passive and compliant kid on the surface, scared of authority, from well educated privelidged background, but by year 10 I realised school was not teaching me anything I could use in the sort of career I wanted, got bored and bunked off lessons often until I was able to be shot of the place a year later.I think probably now kids are less scared of their parents and teachers (thank goodness) so the ones who would have turned up at school but then played up in class/bunked off/sat there miserably hating every day know that they don't have to put themselves in that environment in the first place.
That said,there are some kids who sadly would like to do well and be in school more, but family problems and traumas prevent it being possible.
When I work with families, if school is affecting their mental health significantly and they are genuinely unhappy there, and nothing can be done to change that, I will always advocate them being moved to another school or taken out, even for a short time, of the school environment, to recover and re-group before then ideally moving to a different school.I know I would do the same for my daughter's when they are older.
That's not to say they should be sitting at home gaming or whatever all day- they shouldn't- they need stimulation, learning, socialising boundsries and structure still, but school is often a 'one size fits all' box, and when you add in things such as bullying aswell, why should a distressed kid have to put up with it all.If someone hates a job they get to leave, so why should children and young people be imprisoned in a place they are unhappy...
