There's clearly a concerted attack on teachers coming from RW circles. If you are a teacher, I'm sorry and try to ignore it. Most parents know you're doing your best. My son's teacher must have spent a good few hours yesterday explaining a certain element of maths, not only to

kids, but to confused parents, many of whom haven't done maths for decades, and who certainly aren't used to the methods currently in use.
It's incredibly hard to switch from teaching irl to solely online learning (I know because I have an MA in online education).

The teaching unions are simply protecting their members. It's outrageous to impugn teacher's courage or good will.
I'm not going to RT the people responsible for it, but I think we all know who we are.
