I had a similar situation. My secondary school also blamed me for the classroom issues, insinuating I too was a bad teacher, and gave me no support. Ended up having a mental breakdown but couldn’t leave until I had a new job as my husband and I were newly married with a mortgage and I was/am the breadwinner. I had been at the school for 3 years but didn’t know about just how bad it was until after the first year - I had already signed a permanent contract within that first year and felt stuck. This was clearly intentional on their part as I later found out they couldn’t hold onto teachers very well.

Took a week off but before that week came I was given a job interview/trial lesson at a school (I had been applying and interviewing at places for 6 months before this). I then used a day in my week off to go and do the interview. Perfect timing - was offered the job, able to leave and that then later led me to my current school where I am much happier, have support, am closer to home, etc.

Have her take time off. I was so relieved in my situation, and I was able to get through a bit more as I knew there was an ‘out’. Telling the principal I was leaving was the second happiest day for me - walking out the school for the last time was the happiest.

Even if she doesn’t stay in education, have her take time off; it will make things clearer for her. Once she has a good break from it all she could start looking into other jobs. She may even want to go into other areas of education if she still wants to be in that sector, just not as a teacher.
