Not in UK first of all, but would love to know how many interruptions your teachers cause during the school year.
We have on average 1 strike a year and then a dozen little leaflets threatening strike action handed out throughout the school year. And once a term they have a teachers' meeting, which means school starts at 10.15 and they only do half-day school anyway.
If you have a problem or want to speak to a teacher you have to wait 6 weeks (!) for an appointment because they are "too busy".
AIBU to think it's not the same in England?
