I love the fact that it takes only about 3 posts for someone to basically remind teachers that they aren't special, and everyone has to blah blah. OP was specific about teachers, to be helpful/to direct readers. But nooo, always opportunity for a dig.
OP - both me and partner were full time as soon as our child started school (having both been part time before that). My child started breakfast club and after school club right from her first day in reception. She went in at 7.45 (dropped off by partner who went straight to the station and was at work by 9.30), picked up by me at the latest I could possibly do, which was 5.30. Since covid partner now works from home, so does drop off at normal time. I still screech into the carpark at 5.29 for pick up. I'm part time now, and on the one day I do normal school pick up, we go to the park with a load of other kids - if she did that every day, she'd be bored. I actually think after school club is great. Breakfast club is functional.
If your children have been in nursery, they are probably used to a 'long' day of 8 - 6 anyway. Mind definitely didn't mind it. No issues at all.
I've got teaching friends right now who are trying to move to a school closer to home for drop off reasons (especially where both parents are teachers), so you do have to manage things a bit.
Teaching is my second career, when I first started I couldn't believe that anyone was around in the middle of the day to collect children, 3pm was 'lunchbreak' in my old job. School hours are bonkers really and don't suit the modern world where we need two salaries for a mortgage/rent.
