Not only in Europe, but in Canada too. Think of the union as a corpo offering bargaining and administrative services. Unions compete with each other for workforces. The typical case would be for a newly unionizing workforce needing to choose which union to join.

It is rare, but a workforce can even choose to move to a different union.

But without a monopsony how do these choose your own adventure unions have any real bargaining power?

In countries where meta-strikes are legal, the unions cooperate on basic rights, and strike together when needed. Such coordination is explicitly illegal in the US, and has been since the '30s (IIRC).

It sounds like they'd at least have more power than a single-employer union, by virtue of being larger and having more resources.

I'd much rather run a factory where only 10% of my workers may strike than one where 90% may strike.
