I feel as though you're imagining the Big Bad Union that big companies love to describe. A union can be in whatever form you wish it to be. If software engineers wish to band together to form a union solely to improve their health insurance then they could just do that.
I don't get to pick unions. I get to pick my community support structures. Who I marry, which church,friend group,local community group I join? Those are all voluntary. Unions are not voluntary so they can't really be a community support group in the sense I mean.
You are correct! But we are discussing why I personally would vote against one at an employer. It would take an otherwise reasonable and enjoyable employer and turn them into a place I no longer want to work.
...what do you think a union is?
