I think it's the exact opposite problem the tech industry has.
The film industry has way more talent supply than the employment demands, which naturally suppresses pay. The guilds/unions are a way to increase scarcity to maintain pay and ease hiring.
The tech industry has much less talent supply and much much much more employment demand. Tech might be better modeled after high skilled trade unions (which have a labor shortage) than the comparatively lower skilled film/auto/factory unions (which have a labor surplus).
I disagree with this point to some extent. Look at video game devs, who have similar problems where there’s a lot of labor supply enabling abuses. Also look at the abuse capable of h1b visa holders.
Companies are exploiting because united states want them to. There is a reason why a group of people(mostly Indians) are kept into the state of limbo. The fake fraternity angle is BS. Even the immigrant communities(demonstrated from Iranian immigrants protest against S386) want to keep it this way, so few can get bigger pie at the expanse of other. Everyone needs to know and understand the truth behind the so called fraternity. Would an Asian/Indian/Chinese would get same kind of protection as compared to their white/black counterparts. I doubt it.
It's an example that is fundamentally different from tech work, specifically google. It's a gig based industry with massively high income inequality. Not to mention it's an industry level/dominate union vs a company level union.
Yes, the idea for health benefits was great. But now we see that the SAG is just like corporation - cutting benefits because the highly paid big wigs don't want to pay for them.
