Hey and welcome to DWD.
You have my every sympathy. I used to teach until my husband had a breakdown and I had to quit to look after him, then my own health decreased massively. Now I'm dealing with teachers as a parent and I am shocked and disgusted by the hours they are meant to work. I may send in an email on a Friday night, but I don't expect a reply until Monday, but frequently get replies on a Sunday evening. It's bonkers. We spoke to one of my children's teachers at parent teacher who said that she is expected to work 6/7 days a week. No one can work like that... Sorry, ranting..

Have you spoken to your union?
