Unions don't work the same way in all european countries.
In France, the union I belong to is organized by local company and public service, with a spawling system of dual cascading federations by geographic sector and economic sector.
And there are several competing national union organizations which overlap. I don't know exactly how the other ones are organized
This is the difference between a trade union and an industrial union. You can join an industrial union elsewhere in Europe or even in the US, such as the IWW.
*Devs working in Poland. Unions in Europe are per profession or economic sector not per company.

Austria has basically one big union (ÖGB), in which there are specific unions for different industries.
So, yeah. Every country has their own history and different approaches to unionization.
