These can all be true things. But could you imagine if we spoke about corporations in this manner? "I've worked for corporations and they are a mixed bag. In practice, they often abuse their employees. I've personally witnessed bosses who contributed nothing for years and just played politics." For some reason we hold unions to an incredibly high standard of "no problems, ever" but this is never used to discourage al…
I am very pro-union, but I feel like a part of situation you are describing is because we needs businesses. We don’t necessarily need unions. Without unions, businesses would still be here. Without businesses, where would the unions be? Edit: I would like to reiterate that I am pro-union. I am just saying that unions are optional, but businesses (or the government as some have pointed out) are more necessary from the…
So you need to separate the more conceptual parts of unions - that maybe we should value sustainable and secure employment over shareholder value, that laborers should be able to negotiate collectively and not individually, that you can do good work that is beneficial to the public by prioritizing happy laborers - from the very specific implementation of unions that we happen to have. Without our current model of for-profit businesses, the implementation of unions would not be a coherent concept (and admittedly they are a bit less coherent now and when applied to e.g. tech companies than they were in the past for the businesses for which they were designed - which isn't to say they're the wrong answer, just that they're an awkward fit). But the values are still valid.
As a sibling comment said, worker-owned cooperatives are one model here. Another similar option is very small companies: the concept of a solo founder unionizing makes no sense, but the solo founder of a bootstrapped "lifestyle business" has most of the benefits one generally wants from unions, and communities of such businesses can choose to federate for a better voice in the market. There are certainly a lot of other options besides the idea of a large business owned by its founders or publicly traded.
