I didn't know that about the Ph.D. students in UCU. It figures. Must have been on another thread I mentioned I used to belong to UCU for a brief period many years ago when I had a university admin job just senior enough to get in as academic-related. I found them useless. My employer made a pig's ear of the regrading (Pay and Modernisation) exercise. UCU utterly failed to intervene to get them to do it in a timely or sensible way, and then when the results came back and some people faced huge pay cuts UCU was as much use as a chocolate fireguard representing them as they tried to sort it out.
Meanwhile, every time there was an election for UCU main Executive or whatever it was called, half the candidates would talk at length about international issues, e.g. Palestine. This is not what I was paying my dues for, so eventually I left.
Surely if membership drops enough, the employer will eventually be able to say involving UCU in pension discussions is not appropriate, as most people affected are not members?
I believe Prof Stock left UCU last year. Can't blame her. They have utterly failed her.
