Earlier quoted context omitted.
It depends on the specific industry in tech. Do programmers in general tech startups have enough power? I’d say yes too. Do programmers in the gaming industry have enough power? Definitely not.
The gaming industry has an interesting problem: a lot of fresh college grads that want to work on games because they are passionate about games. In that case, I'm unsure of how unionizing would help much, as publishers could simply invest in games from non-union shops, and happily abandon the studios that are unionized.
and game development work is probably the most trivial software development to move to foreign jurisdictions. unless the union promoters would like video game tariffs.
