They are quite the reverse. It is very, very difficult to stick to a principled stance when you are coming under completely unreasonable (some would say illegal) pressure and bullying from management. This descends from all angles: to declare forthcoming action (strike breaking, which you don't have to do), undermining the action you're paying dearly for taking (100% reduction for 1.9% of your total work plan) by informing them and allowing them to create contingencies, and the horrible, divisive atmosphere caused by management from their bullying other colleagues to undermine the action by marking their work.
I've never known this sector so toxic.
The MAB is not singling out any specific cohort. They are not only refusing to make finalists' work: it applies across the board. That it affects one cohort adversely is singularly unfortunate given earlier circumstances but it is, given the present state of things, inevitable.
I did not take the ultimate decision to call a MAB. My union did that. But yes, I did vote yes in the ballot, I did vote for the continuation of action when this was put to the members, and I did take the individual decision to participate in the action. I don't want it. I've lost thousands out of my pay in what's increasingly looking like sunk costs fallacy and am currently working in an appalling climate. UKHE is in free fall and simply cannot continue like this.
Mumsnet's members can 'condemn' it all they want, especially as they are doing so from a position that clearly lacks understanding. I completely own it. I'll continue in the action for as long as we have a mandate. People are exhausted and on the point of despair - we are not doing this for some sort of jolly.
