Like I said - unions are good in some areas and bad in others. And communism just shows how bad things are when every area covered by unions and everyone equalized
Unions are good for standardized jobs with relatively easily replaced personnel - so called massive professions.
Unions are usually bad for specialized/complex job as they often work on selection basis and for most of career path you are expected not only to perform your job, but also to grow and reach required skills/professionalism to be able do a really complex tasks associated with this job. And if you can't - you better go work in B/C grade companies or even change field.
It's like education works - there is a mandatory curriculum but everyone gets selected in the process, usually in school and then when going to university/doctorate and people graded by their abilities and determination/focus. And no one gives power to students to unionize and than equalize result of this grading as there is no point in scientist who struggle with school curriculum.
And besides - company can only fuck you if you need it more than company needs you. For up-or-out jobs those who remain cost company a lot of efforts to raise and it's a huge loss if they leave, so companies tends to not be too aggressive in people exploitation.
And people are not equal, mother nature made it sure - people have vastly different abilities.
I am pro for equality where everyone can get the same opportunities and whether can you grab them or not is up to you.
I am not a fan of equity where no winners and everyone gets same participation trophy - it kills motivation to struggle and achieve.
People not being equal doesn't imply a hierarchy as your sheeps and wolves analogy does. Where one is weak prey and another is strong predator.
These so called sheep are people with different outlooks and capabilities in areas you simply don't value, either because you were taught not to or because you've fallen to the good old trap of assuming your qualities make you superior to others.
Religious people think they're better because they're holier. Rich people think they're better because they have money. Intelligent people think they're better because they know more. Strong people think they're better because they can muscle others around and round 'n round it goes.
People endure lives where there's no comfort, no improvement and they keep on keeping on. That shows resilience, which is a quality all its own.
So, yeah, mother nature made everyone different. But that's far from meaning better or worse.
Unions are good for every sector, because stakeholder value is always more important than the employee. Since the pandemic executives are more than willing to lay off chunks of an organization to pad profits and beat labor into submission.
Sticking together is the only way to mitigate the advantages those with money have over those without money. 1 billion in the bank is only useful if there's someone willing to do whatever you tell them to for 1 hundred. Which is also why capital is always so obsessed with preventing birth rates from plummeting. God forbid the narrative of "there's not enough to go around" goes away and now people can actually start saying no to capital.
