The pay raises are largely nothing burgers. Same with having a proper writers’ room and the like.
The two main sticking points of the WGA/SAG strike are:
Royalties/residuals. Currently, even if talent IS eligible for them, the streaming services are set up in a way that they will never get them. This comes up near constantly with stuff like “This person wrote Stranger Witcher Tiger King and lives in a cardboard box” style stories. THIS actually would impact (some of) the companies and studios to a very large degree. Like, it wasn’t Band of Brothers or Run Fatboy Run that made The Schwim rich as all hell. Same with most of the sitcom royalty who basically buy a new house every time TBS does a marathon.
AI generated content. I’ve said it many times before, but the only outcome that is likely will be “All past performances are not eligible to be part of training data. Talent will have the option to allow their performance/work to be added to a training data set no less than N years after the first public release”… with a lot of coercion regarding how optional that is (if you thought “Agree to show your tits or we find someone else” was a problem…). This has no real impact currently but will be MASSIVE amounts of money in N years and studios likely expect to be valued based on how much training data they will have.
