Hi, I'm a secondary maths teacher, a DSS who is 7, who I pick up/ drop off at before/ after school club a couple of days each week and a DS aged 2 who is in nursery. I work full time.
I probably do on average about 50 hours a week. Sometimes more - at the min with the lead up to exams I am working more, but I know next half term when I have gained time from year 11 and year 13 leaving that I will be able to do a few less hours at home, due to more free time in school. I work through every break and lunch to get as much done at school as possible. I have been teaching 6 years and do find that I am much quicker at planning, and as EmberRose said I do sometimes just turn up and teach if I'm dead happy on the topic/ class. It is the marking which is very time consuming.
The main thing is getting good childcare, the earlier the childcare opens the easier things will be. I can drop off at nursery at 7.15 and breakfast club at 7.30. I do then have a 45 commute which is hard. I'm starting a new job closer to home in Sept and look forward to being able to be in work at 7.45 instead of rushing in at 8.20. I also leave work earlier than most (around 3.45/4) to miss the traffic and spend some time with my DS before he goes to bed. I then tend to work 7 til 9 most evenings, I like to try and get my work done on a Friday night (rock and roll!) if I have stuff to do at the weekend. Though there are times when I work a few hours on sat or sun afternoon.
When I did my pgce and nqt year I was single and childless. I could work all weekend if I needed to and often did. To be honest I would have found it very tough to start my career with children.
The main thing that I find very difficult when it comes to work life balance is switching off from school. I find it very difficult to not be planning lessons in my head, or thinking about what I'm going to do about the child who failed there mock, or when I'm going to fit in phoning that parent.
I do really enjoying the teaching, working with the pupils and the holidays are a massive bonus - but it's tough.
