> The beauty of a union is there doesn't have to be an objective definition. A union gives you a democratic voice to advocate for what you think is fair. Without organized labor power, your voice is completely ignorable.
This is silly; non-union employees have a democratic voice and the ability to advocate for "what they think is fair", and their voices aren't completely ignorable or else everyone would make minimum wage.
Perhaps there is some gross advantage to collective bargaining, but unions (in the U.S. at least) seem to discourage productivity, competition, and common sense while fostering corruption. These costs drive employers toward automation or outsourcing, thereby eliminating the very jobs they purport to protect. In my view, the cost of unionizing is too high for all but the most extreme circumstances.
> This is a completely naive understanding of what finding a job is like. Leaving a job can be a strike against a person in the hiring process, not to mention it consumes a lot of time, leaves someone uncompensated and without benefits during the process, etc. This also assumes engineer competency is something we can effectively gauge in the hiring process or otherwise (just search "hiring" on hacker news to get the general sentiment among engineers about how good we are at this).
You're conflating efficiency with fairness. Also, there's no need for an employee to quit before beginning to look for another job.
> Imagine if this was the suggestion given to factory workers and coal miners and the early 20th century (not that I think the worker conditions are comparable, but its illustrative of how naive it is to believe that market forces are sufficient for providing fair compensation). This is a marginalist's definition of "fair" that doesn't jive with any real human person's.
See my previous statement about exceptional circumstances, and take care not to confuse a depressed economy with unfair allocation of resources (although both a shrunken economy and anti-competitive practices contributed to poor conditions during the Great Depression). Maybe market forces alone aren't enough to guarantee fair distribution, but your analogy doesn't demonstrate as much.
> The real question is why you are so fervantly against having a democratic voice in the workplace.
This isn't my position, so I'm not sure how to answer your question... It sounds like you're conflating unionization with "having a democratic voice in the workplace"?
