I fully support the strikes, being the child of a academic I've seen first hand the impact of absolutely ridiculous work loads on even full time contracted senior staff. My parents work full time monday to friday, most evenings and weekends, and big chunks of the year I rarely get a phone call or get rushed off the phone due to insane workloads they are having to manage.
Secondly to every 2 hours contact time really at least 10 hours own learning should be done, lectures are meant to provide a ground basis but own learning should be used to make up to top grades and provide solid understanding. Realistically, what the lecturers teach will come from research papers and textbooks that are available to read and learn from, even more so as almost all universities now have online databases where journals are easily accessible. So even as a student myself i dont think strikes mean everyone will fail if people put the work in. I'm a mature student and do a majority of my work from home as unless I've got contact time I'd rather not deal with costs and logistics of travelling in. (Although I hugely support individuals on practical courses with labs which unfortunately the physical side cannot be self taught).
Attendance again, theres very little they will do over attendance, so I personally wouldn't be worrying about attending if it's a definate that there are no contact hours going to be happening. If all the students who are missing lectures due to strike stay home and work from home instead then the university dosent have the resources to chase up 100s of students and they certainly wont remove from the course.
Instead of being angry at the lecturers, instead aim your anger at the institutions which have forced the hand of the academic staff. The decision to strike wont have been taken lightly and many academics are upset at the impact it has on students, but dont deserve to work ridiculous hours at under minimum wage and have no pension security, specially when many are making huge research contributions and changes to policy through research.
Complain at the uni and DEMAND compensation for lost hours, theres a entitlement to it and hit the institutions where it hurts most, their chancellors pockets, dont humour them by attending and spending money on the campus, as then ultimately the university is making no loss, and the impact of the strike is being lost on the university, and it will continue.
Actually makes me angry to see how commercialised academic has become, at the detriment of the people who allow it to exist (There is no university without acadmeics) while they happily spend money on million pound buildings, while there staff are struggling to afford to live, have any home/work balance, and a rising prevalence in mental health issues. Academics should be there because they love their research and they have passion, and passionate people who have the real possibly of making valuable contribution to their fields of interest should not be having to consider if it's a feasible long time career option due to financial limitations. It's a job many academics have dedicated their lives too, research is incredibly demanding and consuming, and this should be reflected in pay, contracts and pensions. And work loads will only increase for the few staff trying to keep it going as younger researchers and lecturers shy away from the difficult and exhausting working conditions they are expected to work under.
