The settlement of the University of California strike is a really big deal. [LA Times article].
In the short term the pay raises are huge: a 46% increase in starting pay for graduate student assistantships. And UC Postdocs will be among the highest paid in the world, making more than starting faculty at many colleges.
In the medium term, academics at every other US university are paying attention. Many will doubtless unionize soon, and some will strike.
But I suspect the biggest impact will be long term. UC has 26,000 graduate students and 6,600 postdocs, all of whom have now seen first-hand what a strike can do. Ten years from now many of them will be faculty across the country, or taking industry positions. This strike could signal a generational change to unionization in academia.
Update 2023-01-25: Rebuttals have been posted by JVB, argent-ions, and Ty-Foxface. And I suspect @UCAccessNow also disagrees with me. (I don't work for UC and wasn't on strike.)
the UAW does not really know how to run an academic strike and made a real pig's ear of it. most of the pay increases are after 2.5 years, which for a 3 year contract ahem 'sucks shit' if i may use a technical term. very little remains of the diversity or access parts of the striker's platform. importantly there is no cost-of-living-adjustment so we're back to square 1 in three years. most pressingly there was no return to work agreement, so now the university that fundamentally doesn't know who struck paid everyone, uaw paid everyone out of the strike fund, and some people who got paid twice paid rent with that money, so its gone. now legally someone has to get paid back(because there's no return to work agreement!) and it's a real shitshow. so. fuck uaw, but it beats not having a union!
