This is very good advice.
As teachers, we all know of pupils who are bullied and end up being shuttled from school to school for a fresh start.
It's often a disaster because the bullying continues because the person being bullied has no strategies to cope.
Hard as it may be to analyse it, if someone is being bullied, doesn't get on with their colleagues and can't stand them, this requires some self-analysis so they don't just swap one set of issues for the same in another job.
Maybe some counselling would help?
The valid questions are why am I being bullied, what should I do to stop this, how can I not allow it to happen again?
Extracting yourself from the situation may be a short term measure.
There is always friction in all workplaces. But how you deal with that is the key.
What isn't clear @thequickbrowndog is if this is the only school you've been in and how previous schools compare.
If this experience is unique to this school, then you should think again about chucking in teaching.
You also need to consider references from your current employer and leaving under a cloud may impact on that as would a medical record of stress/ sickness for MH reasons.
Just tread carefully and consider all your options.
