Actually, that would make it even easier, in theory. You'd meet more of your coworkers and would be able to more easily spread the word and discuss pros/cons, etc.
No my guy, the hero doesn't always win in the real world. This is where you get placed on PIP or start having performance issues, or get a promotion to a different team where there is a clash with your new manager.
Given any opportunity I will always be for a union but good damn if the cards aren't stacked against unions.
That's the difference between us. I've always found a way to get by and any work place or so called boss that wasn't worthy of my time or energy, didn't get that investment.
Maybe I was just raised different but I am more than willing to tell someone to fuck off if/when its needed, it of course starts more diplomatically than a literal middle finger but I was never afraid to escalate to an actual "fuck off, I'm out of here" when it was needed. It's one reason why I work for myself, I only have myself and my bills to answer to.
There is a growing movement towards unions and other forms of collective bargaining. If you want to keep being afraid of your own shadow, that's fine but don't you dare do others the disservice of pushing them away from taking control of their own destinies.
