Some employers (completely non-maliciously, I should add!) simply don't know all the relevant labor law either, like summertime vacation entitlements, how the employee is allowed to search for other work during the notice period, unemployment insurance stuff, etc. It made a stressful situation much better for me knowing I have someone who knows this checking everything and advocating for me.
I keep seeing people say "unions won't work" in other countries. Who knows, maybe they're right. I'm just glad I don't live in one of those, I guess.
Tech workers have thought of themselves as the geniuses, the exceptions, not as part of the general labor pool. And they have been! They have received very high salaries, good benefits, sometimes stock options. There have been a lot of tech workers who have become millionaires - not 50%, but enough that it felt like they had a realistic chance to do so.
It's really hard to persuade people like that that they need a union. Unions are for people who can't take care of themselves, who need a union to protect them from big evil management. Tech workers don't see themselves that way.
Also, unions often have bureaucracy of their own. Tech people generally hate bureaucracy. Having the company's version is bad enough; adding a second one on top is a really hard sell.
So you have a really big headwind for trying to persuade your target members that they should want such a thing.
But you have an opening now, with AI and concerns for jobs. People may be more open to the idea than they historically have been. The problem is, the people that you need to get, the ones who are deciding to implement AI, are typically the ones who still think they're the special ones, the ones who will always have jobs, so they still won't see the need, not for themselves. You have an opening with some people, but I'm not sure it's enough for you to be able to make real change.
Prospect is my union (although I'm a member of a BECTU branch rather than the Tech Workers branch as I work in the broadcasting industry) and it's well worth the dues I pay.
Maybe when I hit peak earnings and no longer get a sizeable raise when hopping jobs every 3-4 years and the personal progression is no longer satisfying, I'd be interested in a union.
Notably, I have never been laid off and I have enough savings/investments to keep my family fed and housed for years if I am without work.
When I stop caring about career progression, about learning and growing, and just want to receive a paycheck for minimal effort until I can't be bothered showing up at work anymore, I'd be more than happy to join a union to ride it out. Until then, for purely selfish and individualistic reasons, I'd rather be solo.
Likely what would happen is by the time I want to join a union, it's no longer feasible for one reason or another, but I'll have enough savings by then (or we're all screwed anyway) to be fine.
