I think that whole thing is just a huge misunderstanding of elmu thinking that whole world works like USA. And even in USA, union members in average earn 18% more than others.
On the other side, strike and unionizing is one of basic workers rights here and you just don't fight unions in EU. As you will be losing more money than if you get to an agreement with them.
When elmu started his crusade against unions, I was laughing: "another USA manager that doesn't understand that he is no longer in states". But I never thought that he will be stupid enough to continue.

I think also that most of young in USA and EU are in misunderstanding what Musk did and what he is fighting against. But I think they should and they SHOULD understand what solidarity means and what it can do. And why employers are trying to discredit unions, prevent them etc. - here you can check the Last Week Tonight on union busting in states: https://www.youtube.com/watch?v=Gk8dUXRpoy8
(the numbers are just for illustration, google them, they are public)
Musk fights against one union. With 100.000 members. That union is in federation with 10 other unions with 100.000 members and federations are joining into confederations.
Even first federations presents a formidable force, from political perspective (number of votes on state elections), to pure money and people power.
You cant win, this is now, for unions and federations of unions, cultural fight. Initial union is no longer important and even if they would want to stop, they cant. If he will be poking long enough whole EU will fight him, from politicians that cant afford to lose votes from unions members and on top of that, do you think that German car industry is happy about him on EU soil? They would gladly cover wages for anyone striking.
If ETUC joins (largest EU trade union), he will be against 45 million workers and 41 EU states, and additional 10 union federations, probably bringing together numbers of 100 million workers, 1/5 of EU population without counting smaller unions. There is no politician that would want to lose their member votes and absolutely no EU capitalist that would be stupid enough to fight them even in worse nightmare. The backlash will be so huge all over EU that he wont sell even a free sample of Tesla car except to the greatest "individualists/fanboys" and they will have car windows broken on daily basis as quislings.
That's why never before something like this happened. As no one would be stupid enough to tease them.
If I would be him, I would pull back when second union was in play and reach silent agreement that wouldn't come to the news. Now, with 20 unions in protest? With two countries involved and potential for whole EU?
That's why I am saying, that he just didn't understand what is he fighting against. My honest advice. Stop. Now. Dont wait.
