I need some unbiased opinions please. For context I have been in this job for 5 years including 1 year maternity. I have never felt like this before, even with similar classes etc. I have a good work ethic and I'm not one to slack off.
I've returned from maternity leave having been made redundant from my HOD job whilst off (loophole legality, I've checked with unions).
We have a new SLT (almost all are new, including exec principal, principal and VP) who are awful. A few weeks back I took a day off as my daughter was rushed to hospital by ambulance. When I called to say I wouldn't be in the next day they told me to arrange other childcare. Not once did they ask if she or I were ok.
My timetable is fully loaded with a third of my hours consisting of age groups and subjects I am not qualified to teach (think not even having a GCSE in these subjects).
I have a new job waiting for January, they wanted me to start sooner but my SLT won't release me from my contract. I will be leaving at Christmas but the job is making me physically and mentally ill. I've had 2 asthma attacks since returning when I've not had an attack in years. I spend every Sunday in tears, terrified of returning. I can't keep up with my exam classes because of the other groups that need so much more. I had PND whilst off and CBT really helped but applying those principles isn't scratching the surface of how this is making me feel.
Would I be unreasonable to get signed off for stress in a couple of weeks? I have signed a contract at my new school so I don't think it would impact that but could it have other long term effects on my career?
