Will they or won't they? Will the NASUWT and the NUT - the two biggest classroom unions - call their members out on strike this spring or not? Angry though they are about any number of perceived attacks on teachers, it is far from certain that either believe they have the support from their members for a full blown walk-out.
Certainly, the NUT has voted not to strike in early March, while it remains unclear whether the NASUWT is in favour of any strike action at all. TES's Big Ed Blog has taken a good look at the situation.
This indecision came against the back drop of a gathering of the world's teacher union leaders in London, which grappled with the globalisation of education policy. It even managed a warm reception for the Andreas Schleicher, widely considered the brains behind the PISA international league tables - and something of a hero for Michael Gove.
Other pesky issues tacked on the blog this week included the imminent scrap over the new National Curriculum, due to be published any day, and the chief inspector Sir Michael Wilshaw's stringent views on the state sector failing its brightest pupils.
