I noticed your two links mention different unions striking; some further research might be important here. One of your links is not graduate students striking, but the union for skilled workers at UCSC. The other is a union-sanctioned strike during (I think) a contract negotiation year. Neither is representative of the assertion that graduate students strike every year.

Sure, not all strikes are officially in the name of the grad students, but (a) the unions act together, and (b) the grad students specifically have gone on strike 3 times since 2013.

Here's the strike from 2013, with grad students and service workers going on strike together: https://afscme3299.org/media/news/ucsc-service-workers-grad-...

The comments on this UCSC reddit thread discuss how the unions have been coordinating their strikes over the last 3 years: https://old.reddit.com/r/UCSC/comments/ese6sz/to_everyone_wh...
