It's OK to think that this is a good thing but this is not the same as a collaborative relationship, like you would have with coworkers or another team at a (non-dysfunctional) company.
Of course, it would be preposterous for workers to be elevating the needs of management over their own needs. After all, no one is looking out for them but them.

And what, precisely, do you think companies are doing?
In Europe it is often the case that companies and unions have a genuinely collaborative relationship where the unions will take the company's needs into consideration, and the company will take the worker's needs into consideration. It doesn't always work out, and each party has their own priorities of course. But it is often not nearly so adversarial as it is in the US. That it is like this is to a large extent a cultural peculiarity of the US rather than an immutable truth.
IF people (incl. those representing companies) were economically rational beings out to maximise their own short-term gain then that would be what would happen. But real people are not, and are often able to see that it creates a poorer, lower-trust society overall if they try to push for their immediate material needs too strongly.
This is of course all backed up by the legal and political systems (which will step in if either side oversteps the mark too far), and a long history in which these norms were established.
US unions can extract short-term benefits if the workers can hop to a comparable employer easily when the employer collapses. If workers in the EU are bound to an employer for 20 years, you need a long time-view.
Meanwhile you read about "All transit workers in <EU Country>" going on strike and causing widespread chaos (because no one else can get to work either) every 6 months or so. Usually, but not always, France.
