sandy from a primary point of view, this is what I do:
Maths I try and mark as much as possible within the lesson. Our school encourages this as things can be addressed within the lesson. If I have ticked a fair amount in lesson, I can normally add a comment and a next step for 30 books in my 20 min break. Yes I work through my break but I'd rather have 20 mins more at home. I print my next steps prior to the lesson and stick them in or if I'm being really organised I print onto stickers. Sometimes I just write '1' '2' or '3' in their book as a next step and then display questions numbered 1/2/3 on the board at the start of the lesson.
English - I don't mark English every single day. It depends what they've done - if it's something that doesn't need to be addressed straight away e.g. A grammar task then I will leave it until I mark something else. I find this saves me time as I can do a quick scan and comment in 20 seconds.
I have a 'seen by miss skeleton' stamp to stamp peer/self assessed work so I'm not double marking it.
Sometimes I mark English in lunch, sometimes after school. Afternoon lessons I try and mark within the lesson again, even if you don't get a full mark done, correcting spellings and ticking good things as you see them really helps when you come to do the final mark.
I mark homework before school.
Get the kids to leave their books open on the page they did their work on. Saves time.
When it comes to planning, don't spend ages considering different options and ideas for activities. Pick one that will do the job and just get it done. I always consider whether the extra time I'm spending on a lesson will be matched by extra learning and if not I don't bother making that laminated cut out flash card jigsaw. Life's too short.
Create displays you can keep up for as long as possible. If you're required to have working walls, staple a wad of flip chart paper to the display and get some magic whiteboards of amazon. Teach directly onto this - display is done.
On days where you have a meeting after school plan things with self marking or minimal/no marking. When you're doing a long writing task plan an easy mark maths.
NQT is hard as you can't reuse planning but it does get easier. And there are schools out there who care about workload. Good luck x
