I've seen a couple of jobs recently asking for a mixture of maths, chemistry and physics, but only teaching up to IGCSE or MYP. The schools in question seem to be reputable, but previous experience has shown me that when this happens it's often a case of HODs and established teachers shafting the new boy with all the classes they don't want to take. Even worse, part of the reason is these people have such poor social skills that only the older students (who are more focused on their exams) will put up with them. And I mean it when I say put up, because the people I'm thinking of were disliked by both students and their colleagues. Maybe my experiences are atypical, but as I've seen this situation a few times I'm wondering is this usually the case?
