Here’s how I think about it —

There’s a value X that’s the absolute minimum you would work for, any less and you quit today.

There’s a value Y that’s the absolute maximum I would pay you, any penny more and I fire you immediately.

Y - X is up for grabs, and there are zero moral proscriptions I would give to any allocation of this between employee and employer. Each and every aspect of the employee-employer relationship is advantaged already in favor of the employer (resource disparity, implicit solidarity from company structure, regulations). Unions tend to reduce my share of Y-X. If I was a laborer, I’d prefer a union.

E: I’ve seen unions that are counter examples to each of your complaints so not really interesting to me to think too much about your own personal experience with unions.

I've seen counter examples of the unions as well. However overall what I've seen has left me with a bad taste.
