The only thing that would make my teaching job easier would be a reduction in workload. Having PPA time at home wouldn't be that useful for lots of people imo.
As it says in the article:
About 10% of teachers’ non-contact time, when they aren’t teaching, is supposed to be ring fenced so they can do marking and lesson preparation in school and not late at night or over weekends. But many report this is taken up with other work demands.
PPA is very little time. Lots of people don't live that near their school. Almost all teachers do hours and hours of work outside of their hours in school anyway. I don't see how it would be that much help really.
