What if they don't? They will simply take the aircraft (or the two aircraft by that time) elsewhere. Too much bases too far from each other, thousands of crew members never meeting each other in person, anyone suspected to form a union fired immediately (like in Romania or Ukraine), no chance to reach the critical mass. Even if the Norwegian flights will ever be done by local crew (instead of the Gdansk-based ones they plan to start with) and they get more benefits/money, the people at the rest of the bases will still get zilch. Huge difference in compensation even between people doing the same job at the same base. Work contract says you need to keep your salary a secret and you can't share it with any of your colleagues. The farce called People's Council is a joke, its members are appointed by the company, "yes men" without exception, remote controlled by the management. Masters of divide and conquer.
