It's all about balance. I became a science teacher at 37, with two young children, one of which is send. if you find a school that appreciates staff wellbeing and work/life balance it absolutely can be done. I can drop my kids at school, I can leave most days to pick them up if I want to, I have time to get them to after school clubs and actually see them. I mark when they're in bed on the odd occasion I have to mark, I managed to do all my lesson planning during my free periods so don't really have to plan at home. As a trainee teacher and then two years as an ect you won't be on a full time table either- you get extra time to get used to planning, marking, prep. There is also a teaching staffing crisis so you'd be able to find a job pretty easily. You'd get a bursary of £15k this year to train to teach English too, the amount changes every year, then the starting wage is £29k after that. Most school accept part time applicants too. I'm not saying it will always be easy because it's not, mock exam marking and exam run up I get utterly exhausted, but that isn't reflective of the whole school year. I love having weekends and holidays off too.
