Earlier quoted context omitted.
What examples do you think of where unions do not/did not lead to more formalized, static, equalized systems, which somebody that likes having impact, being paid and promoted based on his work and not his time with the company etc does not want?
Bewildering syntax aside, that sounds like every big company, ever. Unions don't change the core nature of large organizations, just the power dynamics.
That's not necessarily desirable for somebody that currently has a compensation package that's far above the average.
I've never seen or heard of a union that handles this differently, even if they are "democratic institutions", so I wonder if there are any examples where you bargain collectively, but you don't get the negative side-effects of equal pay for unequal work, promotions based on time spent instead of contributions, essentially tenure for underperformers etc.
