Teachers do have different workloads, you know.
I'm an English teacher. My marking load is much higher than my colleagues in other subjects. My subject is compulsory to the age of 16, which means I always have full classes except at sixth form, but even then, it's still a popular subject. Marking a full class of essays takes about 3 hours. It's not possible to do it faster - you have to read about 6 pages per student. 6 x 30 pages = 180 pages. And on top of actually reading it all, you've got to annotate the issues with it, provide feedback against the marking criteria, etc. You can't make that task shorter. And that's just one class. Most state school teachers of core subjects have 7 classes.
If I have two lots of homework to mark per week, that's 6 hours of work, and I can't do it during the day because I'm teaching, so that gets pushed to after school or the weekend.
I also direct two school plays every year - so that's hours of admin and rehearsals that get added to my workload.
Then I'm also a form tutor, so that's more admin.
And then the lesson planning. I don't just reuse the same lessons again and again every year because my classes change and need things adapting for them, maybe I don't want to teach the same text again, maybe I want to incorporate something new I just learned about or saw or whatever - so that's another few hours' of work.
And then of course there are all the emails, from students and parents and colleagues and SLT. And the data inputting. And the admin of school trips and events and so on. And if there's been a concerning conversation with a student, the admin of that needs to be dealt with. That's usually a daily occurrence.
And I forgot to mention the interminable after school meetings! Two a week at my school, both until 5pm.
I do have free periods, but they're never actually free periods - sixth formers come for extra support, colleagues need help with stuff, you get called for cover - etc.
So when do you do all the work that being in a classroom all day generates?
I genuinely don't know how anyone can work just a 45 hour week and not take any work home.
Perhaps if I weren't an English teacher...
