Although this is often administered by a union, you don't have to be a union member to be a part of an A-kassa.
Essentially, it's an unemployment insurance.
You can go through an union, because they managed to take over parts of the government system that distributes the subsidies, but you are just adding one intermediary to whom you pay a fee and encouraging that (which can be a good thing too, in case they are actively supportive and more efficient; someone local may know better).
Though, what I originally wanted to express, is that in some companies, if you are not member of a specific union, then you do not get access to promotions, to the most interesting jobs, or even getting the risk to getting fired because you suddenly do mistakes and be replaced with someone more union-friendly, etc.
This is the type of protection I meant. Protecting you from their own harm.
Actually I don’t know if they’re on top of or a total replacement, but even as a replacement I’m happy! I work as a consultant so it’s always a little risky finding clients, but my annual take home from the previous year covers the downtime
And honestly I’d argue this fairly liberal approach encourages entrepreneurship because you have so many safety nets
It’s on top of, as the maximum you can get from public unemployment funds are capped fairly low nowadays and rarely reaches the intended 80%, hence why the unions steps in and offers extra insurance
Unions typically offer collectively bargained felt insurance and such here as well
