For pity's sake, stop being such a martyr and giving the rest of us teachers a bad name. No wonder society get fed up of "teachers" moaning.
FWIW. I love my job. I've loved my job since 1999. It's the best job in the world as far as I'm concerned. Teaching children aged 4-11 is such a rewarding thing in life and there is a new story every day to tell my family. My now adult children can still quote and recall some of the more endearing stories from the years past.
I have only had 10 minutes for lunch when I've been determined to finish some marking/planning/printing to save me doing it later.
I accept that I have set toilet breaks. As an adult without a disability, I can cope with up to 2 hours without using a loo. As do so many other professionals in their spheres of work.
I've never bled through, despite having extremely heavy periods. When I've felt a flood, I call a member of SLT to have my class if a TA can't be found. I've taken ownership.
I've only gone without food from breakfast until 3pm if I've been fasting. I've prioritised me. I've taken ownership.
I've worked in 4 schools over my 20 year career. The 1 school I worked in which didn't have a culture of looking after staff wellbeing had my resignation letter after 6 weeks. I've taken ownership.
Because I've taken ownership, I've been to my own children's sports days, assemblies, plays, leavers events etc that have been during the school day. I plough through the paperwork during my PPA and before and after school. I leave by 5pm most days and never do anything at home, except during report writing season and classroom prep in the summer holidays. I skip into work most mornings and come home with a smile.
Expectations of teachers are not way above and beyond other so many other job choices. I appreciate you're jaded, but try telling that to someone on a zero hours contract who gets a 5 min loo break every 4 hours, 30 mins for lunch, working a 12 hour shift.
Good luck with your exit strategy.
