Ahh I see. I'm not aware of that having been a trend here but could be outside the circles involved. The majority of focus I hear on schools at the moment is teacher's strikes, particularly because they're probably the strongest union and most damaging strikes to do in the UK. Schools act as childcare allowing people to work, without schools people also stop working so a teachers strike effectively causes a knock-on general strike of sorts. Could be that this organising is overshadowing these kinds of trends being talked about.
