That unions work in tech companies. Naver/Kakao/Nexon almost simultaneously unionized in 2018, and now some time has passed it is possible to evaluate. It worked great so far.
By what metrics has this worked great? Genuinely curious as I hadn’t heard this before.
But you're not telling us how it's great. You're just repeating that it's great.
Compensation increased rapidly and more importantly compensation became more transparent. Unions collect compensation data and share analysis and anonymized statistics. All unions succeeded at the initial goal of striking down no overtime pay clause in contract. In pandemic, unions represented workers' concern about safety well. Etc.
