My guess is that the ERG are so desperate to get the Retained EU laws bill through first (to move the UK as far away from Europe as possible) that they will cling on until the end of the year. They'll push through incomprehensible/inconsistent legislation with minimal scrutiny in a rush before Christmas.
They dont care about the strikes. I assume Peston was being sarcastic when he wondered whether they reflect at all with what is happening with public sector workers. I am sure parts of the Governement believe the strikes work in their favour (maybe it does with their core base).
I really hope the teaching unions have some cracking spokespeople to get their message across. Parents are bound to grumble but appreciating how and why this has all come about will be key. I suppose they will also be reliant on how much of the media approach it (insert screaming emoji here!).
