Elseforum, I've debated this. I consider it to be more of an inside company lobbying group than a union. In particular, they have no ability to collectively bargain for a contract. None of their wins are things that have been able to be put into a contract.
Furthermore, some of the issues they've brought up have been things that are... not contractural and rather political. For example https://www.alphabetworkersunion.org/press/ceasefire-demand ... while it is ok for an organization to have opinions, things that are not about the contract that the worker has with the company gets into... well... political issues and that can hinder the ability for the group to get a majority representation and be able to do the things with contracts.
