Over here (austria) the unions, which are pretty powerful, argue on behalf of ALL employees in that field. They basically set the minimum pay/benefits across the country for the kinds of jobs they represent by negotiating with the industrial association. By law, the result of those negotiations are the baseline for everyone. And everyone can still negotiate for better terms with their employer.

One benefit the union members have over the non-union ones, though, is that you get insurance for legal counsel, for example. Other than that, union members don't have that many benefits, tbh. I still chose to be a member, because IMO it's the right thing to do.
