US ports longshoremen’s strike (East and Gulf coasts)

A union is required to act in the best interest of every dues paying member. They could be brought up on charges with the department of labor for failing to act in the best interest of every member. We don't/can't/won't trade away jobs.
I get that, but at the same time there are situations where what might be right for one group of members is not right for another group of members. It's unavoidable when they are dealing with people in different life situations that are in the same group. There are inevitable conflicts when you are talking about the interest of a guy who is say 60 and a guy who is say 24.

In other situations, those conflicts often mean that each group gets separate representation, but I get that that might not be possible under U.S. labor laws.

And I didn't suggest that the Union should, would, or could trade away jobs. But it's unfortunately inevitable that there will be job losses in that industry no matter what the Union does.
