I’m a unionized tech worker going on 15 years and many of my close friends from college have similar career paths minus the unionized position. There are a couple who are now in senior leadership management level and make more, but those wouldn’t be unionized positions anyway. Everything considered I make more and have better benefits and conditions as a result of collective bargaining, and all the downsides people bring up I’ve likely had personal experience with, but when I talk about these things with my private-employer friends it usually leads to, “if you think that’s bad…” Like I’ve seen ineffective people be fired and all that. I’ve moved around a bit, had promotions to different salary bands, all within the union.
Overall I think given the amount of capital thrown in to tech industry vs how people work and are compensated, it’s one of the fertile grounds for organization and worker actions. Especially when it comes to outsourcing work to countries where workers can be more easily exploited because the labor laws are so much worse.
