Admittedly most realistic for gc(s)e cohorts, but the dream scenario of a whole day being allocated for marks and associated administration, would be a nice reality if the teacher union(s) were really interested in teacher workload.
Yes, there was a strike. Yet, a good opportunity to use "withdrawal of labour" to in fact re-deploy that labour for far-too-often-free-labour-normally(!) to mark students' exams scripts.
The usual "mixed-bag" some have listened to advice given and changed their behaviour with the concomitant improvement. Some have regressed because "the game is up" and the realisation has arrived (should do something else). Some have been complacent and temporarily underperformed; better to receive the "short sharp shock" now than twelve months from now...
It is a "messy business", to teach. Progress is not linear. Students have good, bad days. Teachers too.
