Dd's science teacher went off sick before the summer holidays last year. So they had supply teachers that last term as well.
She's had four supply teachers since Sept all have left for various reasons. One to work in a childrens home, one for another job, one decided they didn't want to do supply any more.
I'm a bit worried that they're getting no continuity. Is it worth contacting the school and asking what's going on? Part of me thinks there's no point as they're just going to say something along the lines of "yes, we're sorry, we hope the next one stays. But we can't make them and as we don't know if/when the teachers coming back there's nothing we can do".
