It was declared illegal in the EU in 2006: https://www.internationallawoffice.com/Newsletters/Employmen...
This was recently ruled illegal in the public sector (Janus v. AFSCME), because of first amendment concerns (the state is forcing you to pay money for union lobbying).
This hasn't resulted in a drop in membership, in no small part due to many unions adopting freakishly Byzantine opt-out measures, e.g. the ones where there's a certain window of 10 days a year that you can leave (computed relative to when you signed your union card, never advertised by the union — and if the employer even mentions these rights the union might attempt legal action under California law which forbids their employer from doing anything to "deter or discourage public employees from becoming or remaining members").
As French taxpayer I am forced to (indirectly) pay for all French political parties, including extreme right. This money gives political parties some freedom to act, to nourish the political debate... seen as a way to straighten the political debate and the democracy ; good for the general interest.
Still the number of members of a given political movement and the share of people voting for it is giving it the real power. And as someone only forced to give (indirectly) some money to a given movement is then entirely different than being force to join such a movement. And that is the same here for union.
Please note that as a worker, you are forced to "pay" for the stockholder. If you are not happy with it you can pick another oragnisation. Same goes for union, you are always free to join a union free company...
"Congratulations you're hired. We can either hire you with an official job title of an X at wage V or a Y and wage W, Y is a union position, here's the paperwork"
It's not a "closed shop" but in practice if you want to get paid at a level befitting the work you're doing it is. Since unions are
But the important part is: they need to balance the needs of all three parties: the country, the companies, and the workers. It would be stupid to sacrifice one of these for the benefit of one of the other stakeholders, as that would ultimately hurt everybody.
And indeed, the force people to join bit was outlawed in EU in 2006, but it was never particularly popular outside UK anyway.
Perhaps am I ill informed (never been in USA, and my friend living there are not in unions), could you give us some sources saying that what you say is the main form of union in USA today ?
> In the end, employees voted 46-to-37 in favor of unionizing
> As of February 2020, the union was made up of 85 engineers, directors, analysts, designers, coordinators, and customer support specialists

If 40% of the workers are not part of the union, seems that you are free to be part or not of the union. And that the union makes sense to the worker, as more than half of the workforce choose to join.
Money helps, but union main strength comes from number of member and support. So paying for it or being member is in all case 2 very different things. And it seems workers are free to join or not, and most of them decided to join.
I don't know the situation of all European countries, but in France, unions gets some money from their member, but they also get some money from the state (ie taxppayers), and some elected union/worker representatives have some work time paid by the company to work on workers representation and union stuff
EU unions are bigger and more general but aren't allowed to force workers to join, ie EU is a "right to work" area. This avoids most of the problems with US style unions and also gives workers more political power since EU style unions are bigger and can therefore more easily influence national politics.
