> Why the rudeness?

You said I since I didn't agree with you I must not be politically astute so I returned the favour!

> I'd also note that you appear to demand 100% alignment with your ethics from unions in return for your support ("think of any situation"), but are fine with being somewhat aligned with your employer.

But my employer pays me. And they're an essential part of the agreement. The union wants me to pay them, and they're optional, so yes I expect them to do a better job aligning to me otherwise why bother with them? What is the point joining a union, lending them what little power you have, as well as actually giving them money, if they aren't very aligned?

My current work negotiation is me and my employer. I have what I want and my employer has what they want. Why involve a third party, who may want something completely different, possibly morally offensive to me? Why do that?

I guess you're going to say 'because the union acts in your interest'. Well, let me tell you - there's a whole world of people out there offering to 'act in my interest' in return for something. Most of them are charlatans. Beware.

No, I did not. If you can't be bothered to keep track of whom you're talking to, I'm done with you.

> No, I did not.

The person I was replying to said it. You asked why I was rude to them.

You can leave a company and get a new job. That’s a good time to renegotiate your terms of employment. You can even use the impending threat of your departure as a negotiating tactic.

Unions complicate an otherwise cut and dry relationship of your employer trying to extract value from you and you trying to extract value from your employer until you reach an equilibrium.

As a worker, you want "complications" in that relationship, because in its natural form, the balance of power is extremely lopsided toward the employer.

It’s a bad habit to tell people what they want.
