I don't know about you but this year I got a 1.summat pay increase. Inflation is way over that. Last year, and the year before, and the year before etc I also got below-inflation pay rises.
Thinking about it, I've worked in academia for well over a decade. In that time I'm struggling to remember a single year where I got a pay rise that kept pace with inflation. Contrast that to the previous decades I spent working in private industry where pay rises to at least match inflation were de rigueur and then we got performance-related pay rises on top.
Is that not a big enough deal for you to justify a union balloting its members for a strike? If not, what would be? Demanding that universities follow existing agreements about redundancies? Making a stand against the catastrophic funding of higher education? Or do you think that uni staff should just meekly say "Um, I'm not particularly happy about this" as their pay, conditions and the sector as a whole gets eroded?
FFS, I'm not even a member of a union right now but this thread has made me want to be.
