Here's a run-down on my teaching career, in case it helps:
I'm a chemistry specialist and did a PGCE in my 30s, with a baby. I did try to get on a 'learn on the job' route, but there weren't as many around then & ended up on the PGCE.
I really enjoyed it for the first 5 years, but needed to move schools due to relocating, ended up being the victim of horrendous work-place bullying which caused PTSD & I left teaching for a couple of years. Work place bullying is rife in teaching. I wasn't going to go back, but couldn't get a job back in my old field (pharmaceuticals) & anything else would have meant retraining AGAIN, & I couldn't face it.
So, in the end I started doing supply, mainly to test out schools, so I didn't end up in a bullying school again, and I eventually settled on the one I'm currently in, the other 3 I tried were awful in one way or another.
Although I'm settled & I'll stay at my current school, I can't say I'm particularly happy. I'm now 16 years down the line from retraining, and I bitterly regret it. I find the workloads too high & I find the teaching itself a bit boring TBH. I think I'm a bit weird because my favourite part of the job is exam marking - if I could get a job doing that all year round, or something similar, I would!
Also, when I was in my 20s/30s I was never interested in money, but now I'm in my late forties, all my friends & family seem to have overtaken us, & we're stuck really, so I really wish I'd opted for a higher paying career (like pharmaceuticals!). The other thing I detest is the lack of status - most of my in-laws are doctors & I'm definitely perceived as being of lower status, & I obviously earn a lot less money. This didn't happen when I was a research scientist in pharmaceuticals, even though I'm just the same person.
I wish I could get promoted - I'd love to do timetabling/data analysis within an education environment, but it seems to always be a deputy head job, and I had to step right back to classroom teacher after the bullying & I daren't ever move schools again.
Also for me, the workloads were doable when my kids were in nursery because I dropped them off at 7.30am, picked them up at 6pm, they'd been fed & just needed putting to bed BUT I found it a massive struggle when they got older & started wanting to do loads of after school activities. My older DD especially (now 16) still does a sport to quite a high level, so in non-COVID times we are still running her around all over the place. I can't wait for her to pass her driving test.
Sorry, I've rambled on for far too long!
