Google has almost 50,000 employees. Not all of them are intelligent, well-adjusted people.
For example, you casually mention here how you must be black listed because you have seen career problems since.
I don't think I'm "blacklisted". I've definitely caught inappropriate communications behind my back, to the point that I've had to pursue litigation and have collected a couple of (small) tortious interference settlements. "Blacklisted" implies inability to get jobs, and it hasn't been nearly that bad for me because I'm ostensibly good at what I do. I've just had to deal with annoyances, like inappropriate questions on job interviews.
Yet this is nothing to do with unions, and all about anti poaching agreements.
The original purpose of shared blacklists was to shut out union risks ("troublemakers"). No-poach agreements are a similar, illegal, collusion among employers who are supposed to be competing. There are also HR departments in tech companies who share salary and performance reviews down to the level of the individual, and that's also (if not illegal) extremely immoral. Three heads of the same beast (no-poach lists, blacklists, salary databases) but the infrastructure of collusion is the same.
I just find it extremely hard to believe anything you say isn't delivered with an agenda.
I'd like to fix technology. That's an agenda. What's wrong with having "an agenda"? The alternative would be not having one. I wouldn't post on this forum if I didn't care about the future of this industry.
