Questions & Answers about Fagforeningen hjelper oss å forhandle om en ny tariffavtale.
Norwegian normally marks definiteness on the noun itself, using an ending:
- fagforening = a (or any) trade union
- fagforeningen = the trade union
So fagforeningen hjelper oss ... means the union (a specific, known one) is helping us.
If you said:
- En fagforening hjelper oss å forhandle ...
that would mean a trade union (not a specific one) helps us negotiate …
Both are grammatically correct, but they say slightly different things about how specific the union is.
Yes, that is grammatically fine:
- En fagforening hjelper oss å forhandle om en ny tariffavtale.
This would be used if you are speaking more generally, e.g. in a textbook or a description of what unions do in general:
- A trade union helps us negotiate a new collective agreement.
The original fagforeningen suggests that both speaker and listener know which union is being talked about (for example, your own union at work).
