This varies significantly depending on where you are. In Norway, for example, there are 3 main IT unions (and some specialty ones - I think there's one main union for IT workers in finance, for example). Depending on the employer, one or more of the unions may engage in collective bargaining for things like pay structures, yearly raises, and such. My employer doesn't do yearly bargaining with the union - in part, probably, because employees haven't demanded it. The last time the unions had major discussions was when our employer wanted us to sign new contracts, and the unions negotiated to make sure we weren't going to be prevented from doing things outside of work. Generally speaking, the only reason union members bring in the union these days is if they're being terminated, and the union helps make sure it was done properly and works to get the worker the best package possible.
