Why does the former preclude the latter?
> Besides, if I do something so bad my boss wants to fire me, fine then I'll go work somewhere where people want me.
What if you didn't do _anything_ and your boss wants to fire you so badly? What if your boss fired you over Zoom randomly without any recourse?
> The only time unions make sense is when you're doing labor that could be done by anyone and your bus factor is basically infinite.
I disagree with this point. A union makes sense for anyone that is working for a wage. It makes sense to me to work together for all of our benefit rather than me to try to go up against those that pay my wage alone.
Put it another way, I do not think that I can argue well enough to get the actual value that I produce back in my pocket and would love if we all banded together and said "We deserve this much of the value we produce" instead.
