I've worked in 4 universities (non-academic roles - who, by the way, are also striking if in UCU - it's not just lecturers) and what @OntarioBagnet describes is pretty standard.
Research is relegated to weekends and spare time. Student numbers go up and up (and if they don't, courses are cut at the drop of a hat).
The strike is not just about pay, although that's part of it.
Pension is a large part of it. If any of your children go into academia or related work the pension will have been eroded hugely.
The strikes are also about equality and precarious work contracts and work load which is a huge problem for all of us.
All staff I've ever talked to care about the students education but we are also humans who want a reasonable standard of living and a secure old age.
We're not just machines available to teach / look after your children.
A lot of staff will have made alternative arrangements for their students (sometimes under the radar so they can still be seen to be striking). E.g. making recordings available, fitting in extra lectures, making themselves available on non-strike days.
My job involves 1-1 sessions with students. I am cramming in as many as physically possible on non-strike days to try to mitigate the situation.
I shouldn't do that, but I have no desire to make their life more difficult than it will be.
But I am striking and proud to be doing so. I'm doing it for future generations as much as myself.
Solidarity to all UCU strikers & those from
other areas who are striking (train drivers today ✊).
